Toward a generic trawl survey database management system.

This Workshop, made possible by a grant from the Asian Development Bank (ADB) to the International Center for Living Aquatic Resources Management (ICLARM), brought together resource researchers and managers to examine the management of coastal fish stocks and existing resource databases in South and Southeast Asia. The results of the Workshop, documented in this volume, highlight the severe problems related to the management of coastal fish stocks throughout the region. All countries recognize that it is time to remedy these problems and that solutions require multiple action.

Small scale fisheries in the neotrophics: research and management issues

The lack of comprehensive regional treatments of small scale fisheries and the need for improved information for management purposes of this sector in the region are emphasized. Estimating total catches, mapping the seasonal deployment of fleets and quantifying their fishing effort as well as computing catch per unit effort and cost per unit catch for all major gears/species are crucial. In addition, the need to understand oftenly neglected issues, such as the mobility of fisherfolk in and out of the fishery and the role of women in production, distribution and trade are emphasized.

Simple broodstock management to control indirect selection and inbreeding: Indian carp example.

Following a survey of the important traits of Indian carp broodstock at some southern Indian hatcheries, it was found that the broodstock selection was size selective, exerting strong, negative selection of prematuration growth rate and positive selection on age at first maturation. This meant that the hatchery bred inadvertently slower growing and later maturing individuals. Details are given of approaches to avoid such negative selection and minimize inbreeding.

Marine ecosystem management: an ode to odum

Following a description of selected key features of marine ecosystems, simulations based on trophic ecosystems models of the Western Central Pacific Ocean and of the Northern Gulf of Mexico shelf are used to explore potential effects on food webs of major increases in top predator biomass. This results in changes in ecosystem structures that are in surprisingly close agreement with E.P. Odum's theory of ecosystem development towards mature ecosystems, particularly regarding features associated with retention and recycling of detritus.

Knowledgebase for lessons learned and best practices in the management of coral reefs [Thai version]

The GEF Lessons Learned and Best Practices Toolkit (GEF LL Toolkit) provides information on how to design and implement coral reef management strategies. As our knowledge of the issues surrounding coral reef management and how best to approach them improves, revisions of this information can be anticipated.

From sound economics to sound management: practical solutions to small-scale fisheries governance in the developing world

This is a commentary on Daniel Bromley's paper (The crisis in ocean governance: conceptual confusion, spurious economics, political indifference). Taking into consideration the varied context of small-scale fisheries in developing countries, the authors elaborate on three unstated assumptions: information on the fishery ecology; adequate administrative capacity; and sufficiently transparent governance mechanisms, with avenues of recourse to deter elite resource capture.

Escape gaps: an option for the management of Caribbean trap fisheries

The use of escape gaps set in the comers of Antillean fish traps is suggested as a management mechanism for the intensive trap fisheries of the Caribbean. Escape gaps could be rectangular or diamond-shaped. Rectangular apertures provide two dimensions (width and the diagonal) that can be adjusted to permit the escape of deep-bodied slender fishes while retaining round-bodied fishes and crustaceans. Diamond-shaped escape gaps provide height, width and, to a degree, body shape as controlling dimensions.
