Abstract

                From 1991 - 1993 Grouper (Epinephelus malabaricus) brood fish were transported from net cage to stock in 150 - ton out door tank at the NICA hatchery.  The fish were induced to spawn by both hormone induction and water manipuration.  The hormone puberogen was used to induce spawning at a dosage of 50 IU and 100 IU/kg for male and female respectively.  Brood fish induced to spawn by hormone injection produced more eggs and larvae than those spawning natually but the hatching rate was lower.

                Larval rearing was conducted in 25 ton cement tanks at the stocking density of 10 - 40 larvae per litre.  Feed used in this rearing experiment were (1) Brachionus + Artemia nauplii (2) Brachionus + enrich Artemia nauplii (3) Brachionus + enrich Artemia nauplii + copepod + Moina and adult Artemia  (4) Brachionus + both enrich Artemia nauplii and enriched adult Artemia. The results showed that the larvae fed by Brachionus + Artemia nauplii all died with in 24 - 37 days.  The remaining larvae had survival rates of 0.31, 3.99 and 5.33 percent respectively. The production of juveniles increased from 15,498 in 1991 to 123,194 in 1993.
