(Honours) University of Guelph M.Sc. University of Manitoba For the degree of Doctor of Philosophy Centre of Sustainable Tropical Fisheries and Aquaculture College of Science and Engineering James Cook University February 2017 Acknowledgements I am grateful to numerous people for assisting and encouraging me throughout my thesis. First, I thank all the administrative and support staff for helping me directly and indirectly throughout my time at JCU. They have assisted in the office, in the laboratory, at conferences, and in the field; without this network, my project would not have been possible. I am grateful to my friends and family back home for always being supportive while I am off adventuring. They are always hard to leave, but the same great people when I return. To my mates outside the lab, particularly Emma, Dean, Elien, Carlo, Molly, Mike, and Alexia, it has been wonderful to share our experiences. I thank you for giving me a reprieve from work and reminding me there is a world beyond my laptop. I have been incredibly fortunate to work with caring and bright colleagues who have contributed to my research in so many different ways. It has been an honour to work with you and share so many amazing memories. The list is long - Mario, Vinay, Leanne, John, Sam M, Sam S, Elodie, Stacy, Audrey, Merritt, Fernanda, Steve, Leontine, Richard, Karin, Renae, Nick, Ana, Andrew C, Peter, and Madi - I am glad I met you. Never have I been surrounded by so many people eager to work together to make science better. I am especially grateful to my office mate Elodie Lédée. You have suffered my company for over 3 years, always listening to my confused lamentations but tirelessly pointing me in the right direction with your seemingly infinite depository of knowledge – merci. Next, I would like to thank my advisors, Michelle Heupel, Colin Simpfendorfer, and Andrew Tobin. They have supported me throughout my thesis, always taking the time to discuss and take interest in the work I am doing (or aiming to do). It is because of their work ethic, knowledge, and general human decency that I have improved as a scientist and am prepared for the next step of my career. This modern triumvirate is the ideal advisory team, each contributing to different aspects of my gained knowledge, such as critical thinking, project design and organisation, writing, analysis, field work, fisheries, and animal behaviour. Thank you for putting up with yet another Canadian. Finally, a profound thank you to my parents, Don and Debbie. Half the time you have no idea what I am talking about, but you are twice as supportive because of it, and always have been. i Statement of contribution of others Supervision Prof. Colin Simpfendorfer – Centre for Sustainable Tropical Fisheries and Aquaculture & College of Science and Engineering, James Cook University, Townsville, Australia Dr. Michelle Heupel – Australian Institute of Marine Science, Centre for Sustainable Tropical Fisheries and Aquaculture & College of Science and Engineering, James Cook University, Townsville, Australia Dr. Andrew Tobin – Centre for Sustainable Tropical Fisheries and Aquaculture & College of Science and Engineering, James Cook University, Townsville, Australia Financial support Project funding National Environmental Research Program (awarded to Prof. Colin Simpfendorfer and Dr. Michelle Heupel) Australian Research Council (awarded to Dr Michelle Heupel) James Cook University Graduate Research School, School of Earth and Environmental Sciences, and College for Marine and Environmental Sciences (research grants) ii Project funding (continued) AIMS@JCU Pilot Research funding Australian Coral Reef Society Research Award Ph.D. stipends James Cook University International Research Scholar Natural Sciences and Engineering Research Council Postgraduate Scholarship Travel and conference funding James Cook University Graduate Research School, School of Earth and Environmental Sciences, and College for Marine and Environmental Sciences (travel grants) AIMS@JCU Travel Awards iii Travel and conference funding (continued) The Fisheries Society of the British Isles Travel Grant Australian Society for Fish Biology Congress Travel Awards Australian Coral Reef Society Travel Award Data Collection Orpheus Island: Orpheus Island Research Station and staff, IMOS Animal Tracking Facility, Steve Moore, Jacob Eurich, Jonathan Smart, Pasang Tenzing, Vanessa Messmer, Elodie Lédée, Vinay Udyawer, and Audrey Schlaff Townsville Reefs: RV James Kirby and crew, Steve Moore, Fernanda de Faria, Peter Yates, Catalina Aguilar Hurtado, Gemma Molinaro, Samantha Sherman, Franz Fingerlos, Cameron Murchie, Mario Espinoza, and Elodie Lédée Marine Aquaculture Research Facility Unit (MARFU): MARFU and staff, Merritt Adkins, Vanessa Messmer, Leanne Currey, Peter Yates, Nick Hill, Elodie Lédée, and Liana Houston iv Statistical, analytical, and editorial support Colin Simpfendorfer, Michelle Heupel, Andrew Tobin, Aaron Fisk, Elodie Lédée, Leanne Currey, Mario Espinoza, Vinay Udyawer, Murray Logan, Anna Hussey, Katelynn Johnson, Great Lakes Institute for Environmental Research (University of Windsor), and journal editors/reviewers for submitted chapters Administrative and IT support Beth Moore, Glen Connolly, Rebecca Steele, Melissa Crawford, Debbie Berry, Andrew Norton, Malcolm Goon Chew, Courtney MacSween, Glen Ewels, Phillip Osmond, and Jane Webb Cover image Photo credit: Alexia Graba-Landry Copyright and collaboration To the best of my knowledge and belief, the thesis contains no material previously published by any other person except where due acknowledgment has been made.

This fisheries sub-sector plays an important role in the livelihoods of fishing communities, especially those living on small islands. As a member of the Coral Triangle Initiative (CTI), in partnership with the Asian Development Bank (ADB) under RETA [7813], Indonesia (represented by a team from Hasanuddin University) has compiled this academic paper as a contribution towards sustainable management of live reef fish resources in Indonesia. Challenges faced in managing the live grouper fishery and trade in Indonesia include the ongoing activities and practices which damage grouper habitat; the lack of protection for grouper spawning sites; overfishing of groupers which have not yet reached sexual maturity/not reproduced; and the prevalence of illegal and unreported fishing for live groupers. These factors have resulted in declining wild grouper stocks. The Aquaculture sector is, at least as yet, unable to replace or enable a balanced wild caught fishery, and thus there is still a heavy reliance on wild-caught groupers.

  • Demography of a Large Grouper, Epinephelus Fuscoguttatus, from Australia’S Great Barrier Reef: Implications for Fishery Management
    MARINE ECOLOGY PROGRESS SERIES Vol. 307: 259–272, 2006 Published January 24 Mar Ecol Prog Ser Demography of a large grouper, Epinephelus fuscoguttatus, from Australia’s Great Barrier Reef: implications for fishery management Rachel J. Pears1, 2,*, J. Howard Choat1, Bruce D. Mapstone2, 3, Gavin A. Begg2 1School of Marine Biology, and 2CRC Reef Research Centre, James Cook University, Queensland 4811, Australia 3Antarctic Climate and Ecosystems CRC, University of Tasmania, Private Bag 80, Tasmania 7001, Australia ABSTRACT: Epinephelus fuscoguttatus is widespread throughout the Indo-Pacific and features strongly in regional fisheries, including the live reef fish trade. We investigated age-specific demo- graphic and reproductive characteristics of E. fuscoguttatus from the Great Barrier Reef, Australia, and examined implications for resource management. Age, growth, longevity, and the relationships between size or age and female sexual maturity and the recruitment of males into the study popula- tion were examined. Age validation using both oxytetracycline marking and edge-type analysis demonstrated that a single annulus formed each year. This grouper is long-lived (>40 yr) and relatively slow-growing. The size and age distributions of the sexes strongly suggested protogynous hermaphroditism. Histological data suggested infrequent spawning in small mature females. Females contribute very little to reproductive output until about 566 mm fork length and 9 yr of age. Larger females make important reproductive contributions during their 30+ yr reproductive lifespan. Their relatively long lifespan, restriction of males to large size groups, and the disproportionate contribution of large females to reproduction have important implications for the harvest of E. fuscoguttatus. For example, current Queensland size regulations are poorly matched to the spe- cies’ biology because they do not protect the reproductive elements of populations.

  • Phylogeny of the Epinephelinae (Teleostei: Serranidae)
    BULLETIN OF MARINE SCIENCE, 52(1): 240-283, 1993 PHYLOGENY OF THE EPINEPHELINAE (TELEOSTEI: SERRANIDAE) Carole C. Baldwin and G. David Johnson ABSTRACT Relationships among epinepheline genera are investigated based on cladistic analysis of larval and adult morphology. Five monophyletic tribes are delineated, and relationships among tribes and among genera of the tribe Grammistini are hypothesized. Generic com- position of tribes differs from Johnson's (1983) classification only in the allocation of Je- boehlkia to the tribe Grammistini rather than the Liopropomini. Despite the presence of the skin toxin grammistin in the Diploprionini and Grammistini, we consider the latter to be the sister group of the Liopropomini. This hypothesis is based, in part, on previously un- recognized larval features. Larval morphology also provides evidence of monophyly of the subfamily Epinephelinae, the clade comprising all epinepheline tribes except Niphonini, and the tribe Grammistini. Larval features provide the only evidence of a monophyletic Epine- phelini and a monophyletic clade comprising the Diploprionini, Liopropomini and Gram- mistini; identification of larvae of more epinephelines is needed to test those hypotheses. Within the tribe Grammistini, we propose that Jeboehlkia gladifer is the sister group of a natural assemblage comprising the former pseudogrammid genera (Aporops, Pseudogramma and Suttonia). The "soapfishes" (Grammistes, Grammistops, Pogonoperca and Rypticus) are not monophyletic, but form a series of sequential sister groups to Jeboehlkia, Aporops, Pseu- dogramma and Suttonia (the closest of these being Grammistops, followed by Rypticus, then Grammistes plus Pogonoperca). The absence in adult Jeboehlkia of several derived features shared by Grammistops, Aporops, Pseudogramma and Suttonia is incongruous with our hypothesis but may be attributable to paedomorphosis.

  • National Prioritization of Key Vulnerable Reef Fish Species for Fiji, for Targeted Research
    National prioritization of key vulnerable reef fish species for Fiji, for targeted research Coral reef fish and invertebrates sold at the Suva market. Photo by: Sangeeta Mangubhai/WCS Introduction The majority of Fiji’s population is coastal and therefore highly reliant on inshore fisheries for their subsistence and local economic needs (Hunt 1999). At least 33 percent of all animal protein consumed in Fiji comes from fish, and subsistence and artisanal fisheries contribute at least US$59.1 million to Fiji’s annual GDP (Gillett 2009). There is growing concerns for the impacts of present day harvesting rates and methods, especially for vulnerable fish and invertebrate species in Fiji. This is resulting in a progressive decline in fish belonging to higher trophic (feeding) groups, a pattern that is termed “fishing down food webs” (Pauly et al. 1998). Coral reef fish vary in their vulnerability to fishing pressure, and how well they can recover, if fishing is stopped or significantly reduced. Recovery potential relates to the rate at which a species can replace the individuals that are lost to natural mortality and to fishing. In general, the medium to larger carnivorous fish high in the food chain are thought to be more vulnerable to fishing (e.g. groupers) requiring in decades to recover, while smaller fish (e.g. herbivores such as rabbitfish) are thought be less vulnerable (Abesamis et al. 2014). Certain life history characteristics of fish species together can be good predictors of vulnerability at the population level to fishing pressure, including: (a) maximum size; (b) body growth rate; (c) lifespan; (d) natural mortality rates; (e) age at maturity; and (f) length at maturity (Abesamis et al.

Review known spawning areas for pelagic and invertebrate species, with the aim of evaluating these sites as candidate spawning refugia. 2. Evaluate each of the project’s habitat demonstration sites as potential juvenile/pre-recruit refugia for significant demersal species. Rationale for the Two-Track Approach to the Identification of Fisheries Refugia The two main life history events for fished species are reproduction and recruitment. It was noted by the RSTC that both of these events involve movement between areas, and some species, often pelagic fishes, migrate to particular spawning areas. It was also noted that many species also utilise specific coastal habitats such as coral reefs, seagrass, and mangroves as nursery areas. In terms of the effects of fishing, most populations of fished species are particularly vulnerable to the impacts of high levels of fishing effort in areas and at times where there are high abundances of (a) stock in spawning condition, (b) juveniles and pre-recruits, or (c) pre-recruits migrating to fishing grounds.
