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.

  • SOLOMON ISLANDS Can Dopretty Muchwhatever Youwant,Andwillbelimited Onlybyyourimagination
    © Lonely Planet Publications 246 Solomon Islands One of the last South Pacific frontiers, these islands are Melanesia at its most inspiring and secretive. Wanting to get off the beaten path? It’s easy: there is no beaten path. Just you, the ocean, dense rainforest and traditional villages; it feels like the world’s end. In this enigmatic archipelago, blessed with a compelling history, intriguing cultures and natural beauty, opportunities to create your own trail abound. It’s all about eco-travel: climb an extinct volcano, trek across a mountainous landscape as old as dinosaurs, slog through jungle paths to reach secluded waterfalls, and experience the leaf-hut villages where trad- itional culture is alive. Those looking for a bit less swashbuckling and more creature comforts will delight in soothing eco-lodges and the majestic scenery from a tranquil sundeck. This is only the beginning. Divers will be in seventh heaven, whether exploring Marovo Lagoon’s reefs or diving around the fleet of WWII ship and plane wrecks resting on the seafloor between Guadalcanal and Tulagi. Kayaking, surfing and fishing are also here. Above the surface, plenty of WWII relics scattered in the jungle will captivate history buffs. The question, though, is this: after a few years of civil strife, how safe is the country? Thanks to foreign aid, the Solomons is bouncing back and visitors will feel more than welkam. Yes, you can do pretty much whatever you want, and will be limited only by your imagination. SOLOMON ISLANDS The best part is, there’ll be no crowds to share in the experience.
