These are the proceedings of the FAO/AAHRI Expert Workshop on Improving Biosecurity through Prudent and Responsible Use of Veterinary Medicines in Aquatic Food Production, held in Bangkok, Thailand, from 15 to 18 December 2009. The workshop discussed the current status of antimicrobial usage in aquaculture and the impacts of their irresponsible use on human health, the aquatic environment and trade. The outcomes are relevant to the development of guiding principles on the responsible use of antimicrobials in aquaculture.

A second trip to Hubei Province, central China. Sea cage growout of cobia Rachycentron canadum in the Gulf of Mannar. Culture of small indigenous fish species in polyculture with Indian major carps and high value crops along pond dykes. Study on sperm chilled storage of common carp Cyprinus carpio in Vietnam. Culture-based fisheries exchanges between Lao PDR and Cambodia. Culprit behind massive shrimp die-offs in Asia unmasked.

This manual provides practical guidelines for those engaged in the nursery culture of groupers in Indonesia as well as elsewhere in the tropics. It provides information on husbandry of groupers in the nursery phase, to reduce losses due to disease and cannibalism, and thus to increase the profitability of grouper nursing. The guidelines are derived from outcomes of ACIAR-funded research as well as other published information on grouper nursery management.

This manual provides guidelines for the production of tiger grouper fingerlings. It outlines best-practice methods for broodstock maintenance, spawning, egg incubation and rearing of larvae through to 2–3 cm, fully metamorphosed juveniles. The guidelines have been developed from the outcomes of ACIAR-funded research, as well as from the experience of Indonesian, Philippine and Australian scientists and commercial hatchery operators, and published information. It provides an aid for improving the availability of grouper seed stock.

This document presents a tool in the form of an audit table that can be used to broadly screen and identify gaps in the management systems of government agencies responsible for regulating aquaculture. These gaps, once identified, can be a first step toward building regulatory frameworks that can better deliver on jurisdictional ecologically sustainable development and ecosystems approach to aquaculture objectives. The end product of an assessment is a report for consideration by decision makers.
