Grouper Electronic Newsletter

Welcome to the grouper news - a Electronic Newsletter of NACA, in cooperation with ACIAR, APEC, Queensland DPI and SEAFDEC Aquaculture Department, bringing you the latest and best news on grouper aquaculture, coral reef fisheries and aquaculture research and development.

*** Grouper News Issue No. 4 - Jan-Feb 2000 ***



This is the Forth Issue of a "Grouper Electronic Newsletter" which is being circulated through email. The purposes and objectives are to keep members of the grouper discussion group and other related parties updated on the latest information on research and development of grouper and coral reef fish aquaculture. The information available through this monthly Newsletter is also available on the Grouper website.

Many of the articles and news featured in this newsletter will also be published in hard copy in Aquaculture Asia and the SEAFDEC Asian Aquaculture magazines.

To make this Grouper Electronic Newsletter more informative and useful to all of you, comments, suggestions, as well as contributions of articles, news and information on related topics and activities are very welcome. They are coming - slowly - but please send in your contributions regularly to:

If you have contributions to make, please send these regularly to:

Giant Grouper Seed Production in Thailand

The Department of Fisheries (DOF) Thailand, at the National Institute of Coastal Aquaculture (NICA) was able to successfully produce Giant Grouper (Epinephelus lanceolatus) in October 1998 by artificially stripping eggs and milt, then fertilized by dry method. However, the survival rate was very low, and mass mortality occurred after one month post-hatching.

In early September 1999, NICA has made a remarkable success in the production of Giant Grouper fry, by using preserved milt (chilled in refrigerator-2 days), artificially inseminated with fresh stripped eggs. It was observed that the physical developments of the fry are normal, the juvenile grew to about 2 inches in 52 days.

Epinephelus lanceolatus is one of high value grouper species with fast growth rate. Seed supply has been the major constraint for the development of grouper aquaculture. With the success of NICA in seed production, commercial culture of Giant Grouper, and possibly restocking, may become more promising.

The Hong Kong Trade In Live Reef Fish For Food

This is a report prepared by Mr Patrick P.F. Lau & Mr Rob Parry-Jones, which is published by TRAFFIC East Asia and World Wide Fund for Nature Hong Kong. The report provides useful data such as trading quantitative and prices in Hong Kong market, transport methods and countries of export. This report also provides numbers of grouper photos for various species. It also provides information on taxonomy, life history and ecology of several grouper species found in Hong Kong market.

Review of Grouper Hatchery Technology

Successful larviculture of groupers has been constrained by generally poor, and irregular, survival. The principal constraints to successful larviculture are: the small gape of the larvae and hence their requirement for small prey at first feed; and the occurrence of high mortality at various stages through the larval rearing phase. This document, prepared by Dr. Mike Rimmer of the Queensland Department of Primary Industry provides a nice review grouper larviculture technology, and summarises the current status of this technology.

Grouper Research at the Southeast Asian Fisheries Development Center Aquaculture Department

Research on breeding, seed production and culture of groupers at the Southeast Asian Fisheries Development Center Aquaculture Department (SEAFDEC AQD) was initiated following the recommendations of the 1987 Seminar-Workshop on Aquaculture Development in Southeast Asia (ADSEA) which prioritized the departmentís research and development activities. This paper reviews the progress of research and development in breeding, seed production, nursery, and grow out culture of E. coioides at the SEAFDEC Aquaculture Department, in the Philippines.
