Copyright 2020 Bryce Risley All Rights Reserved SENDERS, RECEIVERS, AND SPILLOVER DYNAMICS: UNDERSTANDING TRANSFORMATIVE FORCES OF AQUACULTURE IN THE MARINE AQUARIUM TRADE By Bryce Risley Thesis Advisors: Dr. Joshua Stoll, Dr. Nishad Jayasundara An Abstract of the Thesis Presented in Partial Fulfillment of the Requirements for the Degree(s) of Master of Science (Marine Policy) Master of Science (Marine Biology) May 2020 Industry and academic conversations on aquaculture’s role in the marine aquarium trade are often centered on production advancements, biological and reproductive constraints of concerned species, and conservation deliverables and often overlook the possible socioeconomic consequences of aquaculture production. Due attention is yet to be spent on understanding broader stakeholder sentiment on aquaculture production and the toll it may have on specialized suppliers such as those in the Sri Lankan marine ornamental fishery. Utilizing a framework derived from Coupled Human and Natural Systems, research found suppling stakeholders predominantly unable to participate in aquaculture production due to various access limitations. When viewed alongside increases in aquaculture effort and production in the United States, these limitations indicated disproportions in vulnerability and the adaptive capacity of marine aquarium trade stakeholder groups, warranting concerns of stakeholder obsolescence. To better describe access limitations, a small-scale marine ornamental aquaculture lab was constructed and tested for efficiency using the yellowtail anemonefish. Literature on aquaculture methodologies and recirculating system construction often fall short of describing knowledge and resource barriers faced by practitioners, indicating blind spots in the industry’s approach to advancing production methods of marine ornamental species. Aquaculture efforts demonstrated barriers to educational, technological, and monetary resources necessary to successfully complete the life cycle of commonly aquacultured species. The resulting recirculating aquaculture system may serve as a model for use by practitioners seeking to culture a variety of demersal spawning fishes. This research indicates greater attention should be given to underrepresented stakeholder groups who are presently marginalized by current development trends in marine ornamental aquaculture. Additionally, negative feedback loops generated by environmental and socioeconomic relationships in the described systems suggest extreme caution and immediate action should be taken to preserve the roles and associated livelihoods of key stakeholder groups in the marine aquarium trade. DEDICATION This work has always been a personal dedication to my grandparents, Carolyn Darnell and Fredrick Stanley Wilson. Together, Carolyn and Stan cofounded the Albuquerque Aquarium Association (AAA), which was incorporated into the Albuquerque Biopark in 2006. Their influence on me during my childhood and years as a young adult have seemingly fated this thesis research. Were it not for their work at the Albuquerque Biopark throughout the 1980’s through the early 2000’s, I would not have discovered my love for marine life and the beautiful and complicated world of the marine aquarium industry. i ACKNOWLEDGMENTS First and foremost, I owe my gratitude to the many professionals in the marine aquarium industry in Sri Lanka, the United States and elsewhere in the world who have shared their time and experiences with me. Their knowledge has aided me in writing this thesis and has taught me that there is still so much I have to learn. I thank my advisor, Dr. Nishad Jayasundara, who provided me with the resources and independence to learn aquaculture and biology through practical applications; advisor Dr. Joshua Stoll for sharing his expertise in social science research which helped further the vision of this work; and my committee members, Dr. Aaron Strong, Dr. Christine Beitl, Dr. Douglas Rasher, and Dr. Heather Hamlin for their guidance, patience, enthusiasm, encouragement, and intellectual expertise as I’ve developed this work. I thank my grandparents Stanley and Carolyn Wilson and my parents Edward and Kristen Risley for instilling in me a love and appreciation of nature and wildlife. They privileged me with many opportunities to experience and explore the outdoors and interact with wildlife. I’d like to thank Dr. David Townsend and Dr. William Ellis of the School of Marine Sciences for supporting my research efforts by providing many of the tools and resources. which have contributed to the work in this thesis. Additionally, without the administrative work and the supportive and positive attitude of Carrie Love, it’s likely I’d still be trying to sort out financial and credit discrepancies of which there were many throughout my time in the program. I thank the many undergraduates, Dylan Lucero, Carly Rahl, Stella Moreno, Kelsey Davis, Kari Costopoulos, Brittany Torchia, Jessica Wibby, Josh White, Sophie Fitz, Syeira Clark, Anika Bartie, Abby Bernier, Jason Morrill, Logan Early, Gretchen Spencer, Ande ii Ramirez who expressed interest in my work and sought opportunities to help maintain the aquaculture system which was an integral part of this thesis. iii TABLE OF CONTENTS DEDICATION …………………………………………………………………………………….i ACKNOWLEDGMENTS …………………………………………………………………….….ii LIST OF TABLES …………………………………………………………………………...…..ix .

    Lysmata amboinensis (de Man, 1888) B. Santhosh, M. K. Anil and Biji Xavier IDENTIFICATION Order : Decapoda Family : Lysmatidae Common/FAO : Pacific cleaner Name (English) shrimp Local names:names Not available MORPHOLOGICAL DESCRIPTION The Pacific cleaner shrimp is easily identified by its colour patterns. The body is light brown with one white band dorsally and two red bands laterally running longitudinally. The tail has two white spots on either side. The antennae are white in colour and the first pair has red coloured base. It grows up to a maximum of 6 cm. Source of image : RC CMFRI, Vizhinjam 363 PROFILE GEOGRAPHICAL DISTRIBUTION Scarlet cleaner shrimp or Pacific cleaner shrimp is one of the most popular species of ornamental crustaceans distributed in the waters of the Indo-Pacific region in Indonesia and Sri Lanka. HABITAT AND BIOLOGY It is one of the popular marine shrimp, associated with coral reefs and compatible with smaller sized marine ornamental fishes. It hides in the near shore, shallow and protected areas within a temperature range of 25-30 °C. In the Indo-Pacific areas and the Red Sea, it is mostly found in caves and crevices of coral reefs. It especially needs shelter from predators when it is moulting. It is an omnivore and a scavenger and often feeds on the external parasites of fishes. As its name indicates, this species cleans fishes including moray eels and groupers feeding on their external parasites as well as on mucous and dead or injured tissue. The shrimp moults once every 3-8 weeks and spawns regularly every 2-3 weeks.

There are over 1,700 species of fish here — with a few dozens of them found nowhere else — swimming among what represents 76% of the world’s coral diversity. The park’s crystal waters protect an area stretching across 35,000 sq km (13,500 sq mi), where large gatherings of manta rays, sharks, whales, mollusks, fish and other aquatic organisms are attracted by the rich nutrients brought by strong oceanic currents. Among all this natural beauty there are roughly 50,000 residents living in villages, settlements and the small town of Waisai, surrounded by limestone cliffs shooting from the turquoise waters and by dense forests where the loud birdsong creates a perfect musical background for a tropical paradise. https://www.conservationatlas.org/blog/raja-ampat-marine-park-indonesia-the-heart-of-the-coral-triangle2018 Page 1 of 15 RAJA AMPAT MARINE PARK, INDONESIA: The Heart of the Coral Triangle — Conservation Atlas 12/26/18, 10:08 AM The Coral Triangle is located at the confluence of the Western Pacific and Indian Oceans, spread across the waters and coastlines of six countries: Indonesia, the Philippines, Papua New Guinea, Malaysia, Solomon Islands and Timor Leste.

Since the only previous Mediterranean record of this species was based on a single individual observed in the Tyrrhenian Sea, the present record likely represents an independent introduction that may have occurred through the aquarium trade or via shipping. Two other surgeonfish species, Acanthurus coeruleus Bloch and Schneider, 1801 and Acanthurus monroviae Steindachner, 1876, were previously recorded from the central Mediterranean. While A. coeruleus may have established a population in the Levantine Sea, like A. chirurgus it has only been reported once from Malta (and from the central Mediterranean in general); both A. coeruleus and A. chirurgus are, therefore, considered to be casual species in Maltese waters. In contrast, A. monroviae was reported from several Mediterranean countries including Tunisia and Malta in the central Mediterranean.

Several introduction pathways contribute to these introduction, including Lessepsian migration via the Suez Canal, accounting for approximately 100 fish species, and intentional or non-intentional aquarium releases, accounting for at least 18 species introductions. In the context of the citizen science project of iSea “Is it alien to you?… Share it”, several citizens are engaged and regularly report observations of alien, rare or unknown marine species. The project aims to monitor the establishment and expansion of alien species in Greece. In this study, we present the first records of two popular high-valued aquarium species, the scissortail sergeant, Abudefduf sexfasciatus and the sohal surgeonfish, Acanthurus sohal, in along the Mediterranean coastline of Greece. The aggressive behaviour of the two species when in captivity, and the absence of records from areas close to the Suez Canal suggest that both observations are the result of aquarium intentional releases, rather than a Lessepsian migration.

Justin Marshall 2, Kyle Michie 2, 3, Fabio Cortesi 2 1 School of Biological Sciences, The University of Queensland, Brisbane, QLD 4072, Australia 2 Queensland Brain Institute, The University of Queensland, Brisbane, QLD 4072, Australia 3 King’s College, Cambridge, CB2 1ST, UK *Corresponding authors: [email protected], [email protected] Keywords: Visual opsins, spectral tuning, reef fish vision, anemonefishes, ultraviolet, gene duplication Abstract Many animals can see short-wavelength or ultraviolet (UV) light (shorter than 400 nm) undetectable to human vision. UV vision may have functional importance in many taxa including for foraging and communication in birds, reptiles, insects and teleost fishes. Shallow coral reefs transmit a broad spectrum of light and are rich in UV; driving the evolution of diverse spectral sensitivities in teleost reef fishes, including UV-sensitivity. However, the identities and sites of the specific visual genes that underly vision in reef fishes remain elusive and are useful in determining how molecular evolution has tuned vision to meet the ecological demands of life on the reef.
