Summary:This paper presents the results obtained in Martinique (F.W.I.) since 1985, in rearing the palometa, Trachinotus goodei . The study on maturation conducted on fishes caught from the wild, showed the weight at first sexual maturity was about 350 g. In cages, a long spawning season was observed, including two periods of high sexual activity (February and August). 50 hormonal injections were tried and had induced 19 spawns. No eggs reached the hatching stage. In 1987, studies showed that feeding quality and the use of two different hormones (HCG or LHRH) did not improve the viability rate. Growth performances were recorded on fishes fed on trash fish. After seven months, average weight was about 400 g from 17 g fingerlings.
