South African Shark Conservancy Posts Archives

Thank you SASC!

It is my last week with the South African Shark Conservancy. I’ve spent the last 70 days doing what I love with those that I love and now it’s come to an end. I was quite nervous on my day of arrival to South Africa, but I think I am even more nervous to go back home! I feel as if I have a completely different life out here than the life I lived in the States. This is my opportunity to continue living how I would like to, no matter where the location is. As per my previous post, I have learned a ton about myself and what I would like to pursue personally, professionally, and educationally. I am leaving SASC with a better idea of who I am and what I want to do in the future.

Once I get home I plan to finish my schooling, work, and participate in conservation efforts in Washington State. OSU places a heavy emphasis on getting involved in the community or field of interest and now I understand why! I want to stay active and engaged in the scientific community as I finish my degree. After graduation I plan on taking a gap year to gain more experience and complete other internships before applying to graduate school and hopefully coming back to SASC to conduct more research.

I can’t express how grateful I am to have had the opportunity to work with the SASC team and the amazing volunteers and interns. I have never met a group of people more willing to educate early career scientists with such passion and drive. Thank you for the blood, sweat, and tears and challenging me to be the best that I possibly can in all aspects of life. I will always look at the SASC team as family. I highly recommend the internship or volunteer experience with SASC to anyone who is interested in marine conservation with an emphasis on Catsharks.

A review of my internship experince with SASC

As the internship starts to wind down, I found myself reflecting on the last 9 weeks. In the two months I’ve spent as SASC I’ve endured personal and professional growth that has aided me in my educational development.

2019 has been my year of progression. Throwing myself into an international program working with sharks has been the best decision I made. Through SASC I believe I’ve matured more in the past two months then ever before. The internship with SASC placed me in a position to meet like minded individuals from across the globe converging on conservation efforts. I’ve learned to truly accept and understand different ways of thinking and find coping mechanisms for ideals I don’t agree with. I have a better patience for others with differing work ethics and levels of knowledge. Overall I’ve become a more tolerable person with a better outlook on how the world functions. Outside of personal development, I have learned a menagerie of field techniques that I wouldn’t have gained otherwise.

A few of the people that have made my experience with SASC the absolute best!

The SASC internship is often referred to as a “field work school” meaning that field techniques are emphasized more than other aspects of science. This is exactly what I came to SASC for and I wasn’t let down! Within the first couple of days with SASC I learned how to handline and deploy BRUVs. Thereafter I learned how to snorkel and free dive to catch sharks by hand and went on one longlining trip. As I continued to complete these tasks my confidence and self-competence levels grew. I believe that field work boosted my confidence and allowed me to better present myself proficiently.

To continue, I’ve gained a better understanding of catshark physiology and life history. Thus allowing me to create a study design and construct a research proposal focused on capture and handling stress of the endemic catsharks of South Africa. By attending the South African Shark and Ray Symposium I was faced with the opportunity to meet professionals in conservation and fisheries management across South Africa. I was also able to make contacts that helped me strengthen my study design. Finally, and what I find to be most important, I have an appreciation for fisheries management that I lacked before. I realized how tricky it can be to manage fisheries in nonurbanized areas where the only source of income is what comes in by net that day. Without this experience at SASC I would be lacking a perspective that is vital for any type of management decision.

Cape Town Culture

As you know from my previous post Collaborative Conservation, I have been in Cape Town for the past week at the Shark and Ray Symposium. I wanted to highlight the conference in its own post due to its value in my learning, experiences, and development as an intern; however while attending the conference the other interns and I stayed at a hostel that brought to light global cultural differences.

Upon arrival to Cape Town, we found housing at the Atlantic Backpackers Hostel. I was not familiar with hostels before this experience, but it was a pleasant surprise. The hostel was more or less a dormitory. We were lucky to get our own room, but most other rooms had a residency of up to 6 people. An outdoor area connected various halls and was the “hangout spot” for those that were staying an extended period of time.

Being the social butterflies that we are, we quickly made friends and met people with backgrounds from around the globe. This was my first time meeting individuals from countries like Germany, Saudi Arabia, Switzerland, and the Netherlands. Almost every night ended with a conversation in the outdoor area regarding educational, social, and cultural differences between our home countries and South Africa. Although everyone had varying perspectives, we all agreed that we could learn something from one another.

From this experience I discovered how others think outside of the mindset held by those I am surrounded by daily in Washington State. It was a humbling event that made me realize how much I take for granted back home, such as clean water or the freedom to express myself. I thought I would share my encounter with the individuals at the hostel in this post because it changed my perspective for the better and shaped a new way of thinking.

Outside of the hostel, I found that individuals in Cape Town were more open to tourists than those that reside in Hermanus. Cape Town reminds me of a smaller and slower New York, but the people are extremely friendly and inviting. For example, on our off time an intern and I went shopping (a big mistake by the way…my wallet is hurting) and came across a thrift shop where the workers were dancing and invited us to join in! When you walk down the touristy streets of Cape Town people smile, wave, and spark a conversation. The same cannot be said for Hermanus. Most people will smile, but they go about their day or ignore you all together. I think some of the differences between people in Cape Town and Hermanus come from the amount of tourism interaction that takes place as well as factors like academics, businesses, and wealth.

I would love to explore Cape Town more before I leave the country as I believe it has more to offer than what I was able to experience in my short stay there.

Collaborative Conservation

Recently I attended the 5^th Southern African Shark & Ray Symposium (SASRS). SASRS is concerned with elasmobranchs: sharks, skates, rays, and chimera. This year SASRS focused on the “blue economy” or the sustainable utilization of oceanic resources. Emphasis was made on the necessity to not only conserve marine ecosystems, but to improve alternative livelihoods that depend on the “blue economy”.

One of the keynote speakers, Dr. Alison Kock, initiated the conference with a powerful presentation on the importance of collaboration in conservation. Research efforts greatly improve when backed by various collaborators such as NGO’s, independent researchers, governments, and locals. Scientific collaboration allows for an increase in impact and a maximization of funding, time, and resources. Dr. Kock provided an example of a study published in Nature that drew from more than 150 individuals on the movements of nearly 2,000 pelagic sharks. This study emphasized the necessity of monitoring and improvement of longline fisheries that interact with these pelagic species. Without the help of several individuals in academia, industry, government, and NGO’s this study would be lacking vital factors that ultimately contributed to the CITES Cop 18 Summit.

The presentation by Dr. Kock set the tone for the rest of the symposium. Several talks thereafter mentioned the pivotal role of collaboration in their successes. A personal favorite of mine was a presentation by Dr. Ruth Leeney that utilized local knowledge to determine the distribution and current status of sawfishes (Pristidae) in Madagascar. To do so Dr. Leeney conversed with fisherman and those with knowledge of the local fisheries totaling 173 interviews. From these discussions she determined that sawfish abundance is declining rapidly. A decline in biodiversity is always of concern, but for the inhabitants of Madagascar dwindling sawfish populations meant a decline in the fin and meat trade economy and consumables. At this point of the presentation Dr. Leeney mentioned that her research was successful and relevant but begged the question as to what could be done for the artisanal fisheries that rely on sawfish landings to survive. In this case, where “small scale” fisheries are the prominent source of income, conservation is the last factor in consideration. Dr. Leeney declared that a compensation scheme or supplemented alternative livelihoods need to be established to save the sawfish populations while granting coastal communities the ability to thrive.

Overall, the Southern African Shark and Ray Symposium left me open minded to alternative livelihoods and the complications that come with fisheries management on a global scale. I’ve learned the importance of collaboration and the vital role it plays in successful research and management. I look forward to applying what I’ve absorbed from the symposium to future tasks, decisions, and perceptions.

About my Research Project: Contributions to my Personal and Professional Development

When I first started with SASC, I was presented with the opportunity to work on an independent research project. At first, the idea of having my own research project was intimidating. I had very little experience creating study designs outside of a Field Sampling class through Oregon State University. With reassurance that I would not be alone in my struggles Lauren, a fellow intern, and I created a research project that compares the effects of capture and handling stress induced by different capture methods on Dark shysharks (Haploblepharus pictus).

Our target species: Dark Shyshark (Haploblepharus pictus)

Anthropogenic stress from capture and release (C&R) may cause a decreased survival rate of individuals. It’s important to understand the physiological responses of elasmobranchs captured during hand lining and snorkeling to utilize the most sustainable methods in research and gauge our contribution to post release mortality. As Catsharks have not been heavily studied, Lauren and I, supported by SASC, are able to contribute to further knowledge of the endemic species.

There has not been a vast amount of research done on the capture stress of elasmobranchs as most C&R studies have focused on teleost. A study by Gallagher et al. (2014) on the C&R stress responses of hammerheads, bull, blacktip, lemon, and tiger sharks, found that some species are more vulnerable to capture stress and mortality. In addition, Marshall et al. (2012) found species-specific differences in blood parameters post stress. They also deduced that high accumulations of lactate may lead to irreversible physiological disruptions that can negatively impact survivability. However, we have not found any studies focused on the smaller endemic Catshark species of South Africa.

There is a lack of understanding of the physiological C&R response of Catsharks followed by a lack in understanding of how physiological data should be interpreted to the population level to inform management decisions. Addressing this research allows us to inform managers and stakeholders to better understand the true effects of C&R on Catshark physiology while filling in data gaps. By doing so we will be able to describe the connection between metabolic stress responses and post release survival.

Through SASC I have expanded my understanding of the integral factors that make a sound scientific study. Creating a viable design with several contingency plans has provided me with a taste of what real science looks like. I now have faith in my abilities to formulate a research project and exclude confounding factors.

We also had to present our study design in the form of a research proposal to the staff and interns at SASC, allowing us to receive and digest constructive criticism. These tasks are setting me up for greater professional success and have grown my personal communication skills.

I have about three weeks left with SASC and look forward to hopefully collecting enough data samples for statistical analysis.

Future Professional Learning Opportunities with SASC

I have approximately five weeks left working with SASC, time has flown by. I’ve learned SO much since becoming an intern. I have a firm grasp on how tasks are completed at the facility, but there are several opportunities coming up that will allow me to improve my professional learning in the latter part of my internship.

I believe I’ve mentioned that a fellow intern and I have created a study design to investigate capture and handling stress of snorkeling and angling on dark shysharks (Haploblepharus pictus). We are responsible for producing the objectives, aims, research question, hypothesis, methods, contingency and budget plan for the entire study. By doing so I’ve exercised some of the ideals taught at Oregon State University (OSU). However, we are now in the process of implementing the pilot study that may change our experimental design all together (we are already back at the drawing board..). Creating this study has broaden my professional learning because it has shown me firsthand that science is fluid and ever-changing. I expect that my professional learning will improve as we collect experimental data, trench through statistical analysis, and create a presentation of the findings. These are valuable skills that I am glad I am test driving at the conservancy where there is plenty of guidance and room for mistakes.

In addition, the entirety of SASC will be attending the Southern African Shark and Ray Symposium. I have attended one other professional conference that focused on fisheries management in the Pacific Northwest, thus I am excited to see what is currently taking place across South Africa. The conference will provide me with the opportunity to explore my professional persona, including my mastered elevator speech, and connect with international professionals.

I am looking forward to elevating my professional learning in the coming months and portraying my skills to OSU, SASC, family, and friends by the end of my internship.

A Washingtonian in South Africa: Observed Cultural Differences

It has been about a month since I started my internship with SASC. Within the last 30 days I have noticed various cultural differences and challenges with rewards and surprises along the way.

Aspects of life in South Africa revolve around racial issues that exist due to apartheid. Although apartheid ended in the 1990’s, political unrest is common. I have noticed some petty racism, but not at the level that tabloids depict them to be. Although that doesn’t mean the level of racism portrayed in the media does not take place.

One of the major surprises that I am experiencing while out here is the gap in socioeconomic status in Hermanus; A common intern house-hold topic. There is the upper-class, which seems to be a very well off older crowd or the lower-class that may reside in townships. From what I have observed there is very few middle-class individuals.

I can only compare my experiences and perceptions to that of Washington state, where I originate. Back home there is a plethora of individuals in each class, with plenty of roaming in between. The opportunity of those residing in Hermanus to travel between socioeconomic classes does not nearly match that of Washington. Talking with locals and the staff at SASC, it seems that it is difficult for people of color to obtain jobs and afford proper housing. The ideology that skin color can depict how you are able to live your life is not a new concept to me but is one that I’ve never seen with my own eyes.

An example of what a township looks like

Due to South Africa’s history and the prominent political unrest, I have also observed a fear of those that live in townships, even among South Africans that grew up in Hermanus. Locals have described that townships are to be avoided as best as possible during the day and to be avoided at all costs at night. I could compare this to being fearful of certain neighborhoods in Tacoma or Seattle, WA, but the fear is a step further in Hermanus. The attitudes I have observed while out here are much different than that of home, but that is to be expected with a violent history.

I am hoping that in the following month I will gain a better understanding of South Africa’s social dynamics through a township tour. These tours are led by individuals that live in the townships. Providing people with ample opportunity to get to know the locals, their ideals, and differing perspectives.

These are a few examples of the most prominent cultural differences that I have noticed in my short time here at Hermanus. I look forward to facing new cultural challenges in my remaining time here.

Personal and Professional Development

As an intern with the South Africa Shark Conservancy I am learning a ton about myself on a personal and professional level. My personal development has skyrocketed in the three short weeks I have been here and my professional development is finally starting to take shape.

This internship brings people from around the world to one central location where we have to eat, sleep, and work together 24/7. There is a mash up of cultures, perspectives, and backgrounds that are shared at the dinner table and enrich the lives of others. The interns are compiled of world travelers, students, scholars, and citizen scientists with a common passion for marine conservation and fishes with cartilaginous skeletons, dermal denticles, and large livers. Through these people I have learned to be confident in my abilities and outgoing. I have grown to understand other cultures and viewpoints that some may not be able to wrap their heads around. Most importantly, I have learned to communicate across language and knowledge barriers. For example, some volunteers or interns do not come with a scientific background but have an interest in marine conservation. When talking about ecological or physiological processes, I learned to break down the scientific language so that I can communicate effectively with others. Not only do I take that as personal development, but as a professional development as well.

The first group of interns that quickly became my family

In terms of professional development, my communication skills have graduated. I can communicate with colleagues, managers, recreational fisherman, and tourist to portray my role as an intern with SASC. Scientific interpretation is a factor that is heavily discussed in the field of fisheries and wildlife. Within my time here I feel that I am better suited to interpret data and information in a way that stakeholders and the public can understand. In addition, social media plays a large role in professional development at SASC. I am tasked with creating a “brand” across several social media platforms to stay in contact with people in my field of interest. Finally, I have recently discovered what I would like to do with the Fisheries and Wildlife Sciences degree in the future. I look forward to working in the field of fish physiology thus SASC has catered my scientific project towards physiology. As of this week, another intern and I are creating a study design that investigates the physiological metabolic response of the endemic catshark species of South Africa when captured via snorkeling or hand-lining. This project has solidified my interest in physiology and sparks my interest for the future!

In the end, I have only been at SASC for about 3 weeks and have gained more personal and professional development than I could have ever imagined.

SASC’s Role in Sustainability

The South African Shark Conservancy (SASC) is settled in the Cape Whale Coast Hope Spot (CWCHS). An area on the tip of South Africa that is abundant with marine life and showcases the marine Big 5: whales, dolphins, sharks, seals, and African penguins. This positioning allows the conservancy to focus on marine life that is not widely understood. Instead of targeting larger pelagic predators such as the White shark (Carcharodon carcharias), the conservancy focuses on endemic and commercially valuable species. By focusing on these species, the conservancy guides managers on effective policy making and management plans.

An overview of the Cape Whale Coast Hope Spot

There are several shark and teleost fisheries surrounding the CWCHS that are unsustainable in practice. Fisheries are prone to bycatch, the accidental collection of non-target species. About 49% of chondrichthyans in South Africa are subject to bycatch or are targeted for commercial use (Silva et al. 2015). Previous records of bycatch are inadequate due to data gaps and generalization in species identification. SASC is filling in the data gaps by tagging any shark specimen encountered through long lining, hand lining, or snorkeling.

Some of the largest commercial uses of South African sharks include finning and harvest of the vitamin rich liver. The fins of sharks are commonly exported to Hong Kong, Uruaguy, and Australia for consumption and medicinal purposes. Shark livers also have a substance called squalene that is used in a variety of beauty products. If left unmanaged several shark species will end up like the commercially extinct soupfin shark (Galeorhinus galeus). As an intern I am contributing to reaching more sustainable practices in fisheries.

To have sustainable marine resources, local communities must understand what is taking place in their waters. Education on how sustainable fisheries function and the actions individuals should take when recreational fishing is just as vital to conservation. SASC offers tours of the facility, led by interns, that provide tourists, locals, and students an overview of shark conservation. During the tour we debunk myths and irrational fears by having positive human – species interactions with sharks in the lab.

Overall, the South African Shark Conservancy is focused on aiding managers and the government with policy decisions based on scientific data in hopes of inducing sustainability in fisheries. While educating the public about marine conservation and their role in ecosystem functions.

About Myself and The South African Shark Conservancy

My name is Nomi Samuel, I’m an E-campus Fisheries and Wildlife Sciences Student at Oregon State University (OSU). As an E-campus, or online, student I have found it extremely difficult to gain the field experience that is required by employers. I came across the South African Shark Conservancy (SASC) Internship position through the Internship Coordinator at OSU. I applied for the position with no faith that I would land it… but here I am 2 months later finished with my first week as an Intern!

To provide you with some background, SASC was founded in 2007 in Hermanus, Western Cape. The conservancy is located within Walker Bay, an area with over 60 species of sharks, rays, skates, and chimaera. The conservancy is working on multiple projects to include estuary monitoring and species diversity and abundance of endemic cat sharks. These studies help the government and local communities understand what is taking place in their waters and the actions that should be followed for sustainable fishing and conservation.

As an Intern with SASC, it is my responsibility to aid in the studies and tasks taking place. There will be time in the lab where I will provide tours for the public outreach, time devoted to creating my own brand and building a professional portfolio, and time in the field fishing or working on studies.

For example, this week we deployed BRUVs (Baited Remote Underwater Videos) to measure species diversity and abundance and how that is affected by bait types. The rig set up allows a GoPro to capture footage of any animals that come to check out the bait canister attached to the other end. Although the visibility underwater is quite poor, we captured footage of a Cow shark trying her hardest to get to the bait.

When underwater visibility was too poor, we utilized hand-lining. Hand-lining is basically fishing without a rod. The other Interns and I spent six hours in Walker Bay trying to catch sharks. This was my first experience fishing so I did not expect to catch anything, but surprisingly I caught about 4 sharks (and gained the nickname Shark Whisperer). My proudest catch was a meter long female Pyjama shark (Poroderma africanum) that was carrying an unfertilized egg.

The Pyjama shark I caught demonstrating the characteristic donut-shaped defense mechanism that cat sharks take on.

The Internship position at SASC will allow me to gain the hands on experience I have been looking for as an E-campus student while contributing to the conservation of endemic cat sharks and other elasmobranchs in one of the worlds most important biodiversity hotspots!
