Aquaculture producers in Africa experience similar challenges to practitioners around the world but often more acutely, particularly in rural areas. Limited access to capital, quality fish feed and fingerlings, and inadequate training and technical knowledge are but a few. Despite these challenges they press forward and do their best with what is available. Numerous NGOs and other cooperative agency programs contributed to the meeting, demonstrating their commitment to developing resources and empowering the people in up-and-coming aquaculture areas. There is no question that with all of Africa’s natural resources and dedicated people it can become not just a participant in global aquaculture growth but a potential leader. I look forward to seeing many of you at our next meeting, Aquaculture 2025, to be held in New Orleans, LA, USA. This meeting, with the theme “Innovation Through Technology” promises to be one of our biggest as it combines the annual meetings of the United States Chapter of WAS, the National Shellfisheries Association, the Fish Culture section of the American Fisheries Society, the National Aquaculture Association, the World Aquaculture Society and a host of other professional aquaculture and species-focused groups. — David Cline, President, World Aquaculture Society Africa: A Potential Leader in Global Aquaculture Growth I have just returned from AFRAQ 2024 in Hammamet Tunisia. What an outstanding meeting. I was inspired by the number of participants and all the different countries represented. There were over 1200 attendees representing more than 70 countries. Fifty-five quality exhibitors provided information on the latest products and technology. Other booths highlighted great projects involving numerous countries. The program committee pulled together an interesting program representing farms, research institutions, NGO’s, government agencies and more. We owe special thanks to all of the sponsors and organizers including conference chair Nadia Cherif, the entire steering and national organizing committee, program chairs, Peter Britz, Judith Makumbo and Nevine Abou Shabana, the African Chapter Executive Officer, Blessing Mapfumo, and the entire African Chapter Board. It goes without saying (but we should thank them more often) that the conference management team did a stellar job organizing the event. The student workers (and presenters) showed great enthusiasm and competence and should give us confidence in the next generation of aquaculture professionals. I have been a WAS member for over 30 years, and it has been exciting to see the growth and enthusiasm present at this meeting. In just 5 short years the African chapter has rapidly matured, and I am sure there are many more great meetings in

WWW.WAS.ORG • WORLD AQUACULTURE • DECEMBER 2024 3 Editor’s Note From an aquaculture producer’s standpoint, animal health and welfare are the most important components of biological performance. And, accordingly, economic sustainability. Few would argue the fact that stress plays a crucial role in the health status of aquaculture stocks, and most successful operations have learned to minimize stress throughout the production cycle. However, recent concerns over welfare of cultured fishes and crustaceans have resulted in regulatory updates and public awareness campaigns that often portray aquaculture in a less than flattering light. For many consumers, perception is reality, and we as a diverse and often fragmented global food-producing sector continue to struggle with misperceptions on many fronts. Equally concerning, however, is the precedent being set by recent events related to aquatic animal welfare in Europe and elsewhere: these regulatory and corporate policy changes affect food security in spite of often being based on inadequate scientific evidence. This follows a general trend in society wherein many individuals increasingly embrace only those scientific findings that align with their world (and political) views, whether the topic is vaccine efficacy, climate change, the utility of GMO crops and animals, or in this case the question of sentience in various aquatic organisms. Consider the impact of one particular document that was published in 2021 and included a number of aquatic animal welfare recommendations that shaped subsequent legislation. The study incorporated eight arbitrary criteria to attribute sentience to a number of aquatic invertebrates. Perhaps even more arbitrarily, the authors assigned categorical levels of confidence to their own conclusions. Recent arguments as to whether fish, crustaceans and now, even insects and fungi can 1) make “conscious” deliberated decisions, 2) exhibit the capability to learn and remember, and 3) experience pain and suffering all conveniently sidestep the question of whether these organisms are “conscious of” or simply “responsive to” stimuli associated with potential injury or benefit. Clearly, there is a profound difference. And, the available science is generally unconvincing when research results are interpreted through the critical lens of assigning sentience. In the case of decapod crustaceans a number of authors have made the decision (albeit subtly) to simply equate “responsive to” with “conscious of.” No studies to date have objectively and definitively described stressful pain in crustaceans, nor have any investigations confirmed the existence of such a phenomenon scientifically. Very few multicellular organisms would have evolved to their current form without some means of perceiving their immediate environment and avoiding negative outcomes in general. Yet when the proposed criteria for “some evidence of sentience” in aquatic organisms are critically evaluated, apparently everything from clams, to copepods, to jellyfish should qualify. This, however, has encouraged a number of pundits, philosophers and pseudo-scientists to disregard the traditional scientific approach while claiming that specific avoidance behaviors in a number of aquatic species are “suggestive of,” or “consistent with,” or “likely” associated with the “concept” of pain, without any definitive, repeatable proof. Those who insist on declaring that numerous aquatic organisms are sentient have generally dismissed or failed to entertain any discussion of flaws in their conclusions, ignoring more rigorous reviews that have demonstrated scientific evidence to the contrary. While aquaculture in general has made great strides in advancing animal welfare in recent years for both economic and ethical reasons, our focus now must, unfortunately, be two-fold: to continue our progress in welfare practices while discrediting the proliferating propaganda based on flawed “science” and biased agendas. Fortunately, there is an abundance of sound science available to answer some of the sensationalism. An excellent and quite thorough review exposing both the shabby and solid science behind arguments raised by some sentience advocates was published several months ago. I strongly recommend every aquaculture stakeholder (and critic) read it. It will take substantial time and effort to package and deliver objective information on animal welfare in aquaculture in a format that can effectively reach policy makers and the general public. We all must redouble our efforts to be familiar with these issues and the legitimate science behind the debate. — C. Greg Lutz, Editor-in-Chief Not All “Academics” Embrace Sound Science

4 DECEMBER 2024 • WORLD AQUACULTURE • WWW.WAS.ORG It is an honor to introduce myself as the new President of the Latin American and Caribbean Chapter of the World Aquaculture Society (WAS). I am excited to begin this new chapter with an exceptional team, which includes Dr. Marcelo Shei (Brazil), as president-elect, Dr. Jesaias Costa (Brazil), Laura Silva as Secretary and Dr. Juli-Anne Russo (Jamaica) and Adriana Muñoz as Directors. I deeply appreciate our outgoing president, Francisco Javier Cordero, for his invaluable leadership and commitment, who will continue to provide us with his support on the Board, sharing his experience to continue strengthening our community. Special recognition and thanks to Dr. Maria Celia Portella for her valuable support on Board duties. An Unforgettable Event in Medellín I want to extend my recognition to everyone who made the success of the recent event in Medellín (September 23 to 27) possible. Thanks to their efforts, we managed to bring together 2,211 attendees from 5 countries, with an outstanding participation of 246 students, the presentation of 584 abstracts, 193 posters, and 391 oral presentations distributed in 61 sessions, in addition to having 64 booths at the commercial exhibition. This event marked a milestone, especially for the space dedicated to new generations who are beginning to forge their path in the exciting world of aquaculture. Under the motto "Weaving networks: passions that connect, voices that inspire," the 64 participating students had the opportunity to develop interpersonal and professional skills through personalized mentoring, networking activities and workshops focused on key topics such as nutrition and feeding of aquatic organisms, sustainable aquaculture, and agribusiness. These initiatives reinforce our Society's commitment to professional growth and connection between generations. Opportunities to Participate Looking ahead, I want to inform you that at the beginning of 2025 we will open new calls to join the Board of this chapter. I invite you to reflect on possible candidates and prepare your proposals. The active participation of our community is key to continue promoting aquaculture in the region. A Call to Action Finally, I want to emphasize the importance of each of us, as part of this noble aquaculture activity, assuming the role of ambassadors in all possible forums. We must promote the relevance of aquaculture projects, which are not only sustainable, but in many cases are even regenerative, contributing to the well-being of our communities and ecosystems. Furthermore, I encourage you to invite your colleagues, aquaculturists and students to join our Society. Take advantage of the promotions available for registration and help strengthen our network, which continues to grow and evolve for the benefit of aquaculture in Latin America and the Caribbean. Together, we will continue to build a bright future for our industry. Thank you for your trust and commitment!

14 DECEMBER 2024 • WORLD AQUACULTURE • WWW.WAS.ORG • Stites, W., Weldon, A., Reis, J., Ito, P., Rhodes, M., & Davis, D. A. (2024). Evaluation of a carbohydrase (xylanase and glucanase) enzyme complex in diets for Florida pompano Trachinotus carolinus. Journal of the World Aquaculture Society, 55(5), e13095. https://doi.org/10.1111/jwas.1309512 Similar to other aquaculture species, Florida pompano, Trachinotus carolinus, can be reared on diets that utilize soy-based protein; however, carbohydrates and other anti-nutritional factors can affect digestibility. This study investigated the use of dietary carbohydrase enzymes to improve carbohydrate digestibility for Florida pompano. The authors utilized the carbohydrase enzyme complex (Natugrain® TS L, BASF Corporation, Ludwigshafen, Germany), which consisted of endo-1,4-ß-xylanase and endo-1,4-ßglucanase and was designated Xyl+Glu, in juvenile pompano diets and determined the effects on growth performance, feed utilization, and digestibility. A growth trial was conducted in a recirculating system using four iso-nitrogenous (40%) and iso-lipidic (8%) test diets consisting of 0, 0.015, 0.030, and 0.045% of Xyl+Glu. No significant differences (p>0.05) in growth and feed conversion were observed; however, there were significant differences in the thermal growth coefficient (TGC) between the 0.015 and 0.030% diets. All the diets containing the enzymatic treatments showed significant differences in apparent digestibility for crude protein compared to the basal diet. Based on the digestible protein improvements, the authors calculated a 3.37% improvement in available protein for Florida pompano when fed this enzyme complex. They suggest that further research is needed that evaluates different types of exogenous enzymes to improve plant-based diets for Florida pompano. • Wang, T., Wang, F., Sun, N., Cui, G., Chen, Y., Zhang, M., Sun, S., Ma, R., Sun, C., &Han, H. (2024). Effects of Bacillus cereus YB1 on growth, intestinal digestive enzyme activity, liver antioxidant enzyme activity, and intestinal structure of black rockfish, Sebastes schlegelii. Journal of the World Aquaculture Society, 55(5), e13078. https://doi.org/10.1111/jwas.13078 Probiotic use in aquaculture has increased and is viewed as a potential means of improving health and reducing the need for antibiotic treatments. The authors of this study investigated the effects of feeding Bacillus cereus YB1 to juvenile black rockfish (Sebastes schlegelii). They compared growth, intestinal digestive enzyme activity, liver antioxidant enzyme activity, and intestinal tissue structures following feeding of four diets: a control group with no YB1 supplement in the diet and three treatment groups E-L, E-M, and E-H containing 105, 106, and 107 CFU/g B. cereus YB1, respectively. Results from this study showed a significant increase in weight gain and specific growth rate and a reduction in feed conversion rate in fish fed the three diet treatment groups. Along with the observed growth enhancement in black rockfish following feeding of B. cereus YB1 strain, antioxidant enzyme activity in the liver and histological gut structure was enhanced. The authors therefore suggest that including B. cereus YB1 as a diet supplement during black rockfish farming could provide eco-friendly benefits associated with enhanced growth and health.

16 DECEMBER 2024 • WORLD AQUACULTURE • WWW.WAS.ORG Aquaculture Engineering Society Membership Opportunity Michael Timmons The Aquaculture Engineering Society (AES) was established 30 years ago by a small group of individuals passionate about bringing engineering to aquaculture. At the time, aquaculture was starting to supply an increasing percentage of our global seafood, helping to meet consumer demand. Back then, that number was less than 10%, and now aquacultureproduced products exceed 50% of the seafood supplying the global market. Seafood demand continues to increase, and wildcaught seafood supplies remain static, leaving aquaculture to meet the increasing demand. The AES is needed throughout the global aquaculture sector now more than ever. The Board of Directors seeks to increase membership and engagement by providing real value to our members, and as the newly elected President of the Society I am pleased to convey this opportunity. As the saying goes, Show Me the Money, or in this case, Show Me the Value before I invest any dollar/peso/yen/euro/dinar/ CHF/yuan, etc. So the AES is offering FREE membership for the remainder of 2024 and all of 2025. During this period, we intend to demonstrate the value of the AES through professional networking, educational webinars, special conference sessions, and discounted offerings to various goods and services, particularly from our commercial sponsors. Here is the link to join the AES for free: https://www.aesweb.org/members/join To provide maximum value and demonstrate that the AES is a dynamic organization whose purpose is to serve its members, please provide us with input on how to do that, and we will do our best to meet your needs. As a start, the AES is offering new members the following in 2025: • Access to all society webinars at no cost • Online subscriptions to Elsevier™’s Aquacultural Engineering Journal for $75 (previously $170) • Hardcopy subscriptions to our journal for only $100 (previously $195 ) • AES members will receive discounted registration at Aquaculture 2025 (March 6-10 2025, New Orleans, Louisiana, USA) for being members of an associate sponsor organization ($95 discount). The AES has organized special conference sessions for Aquaculture 2025, and these special sessions are FREE to all who attend Aquaculture 2025. The AES looks forward to welcoming back previous members and seeing many new members join with this new initiative.
