Resumo: | 20 and 50 µg.kg·1 doses of [D Trp6] LH-RHa analogue proved to be effective in inducing and synchronising spawns in red drum, Sciaenops ocellatus, in the French West Indies tropical conditions. The study of oocyte development through steady ovarian biopsies allowed to carry out injections at different stages. The influence of female ovarian development state at stimulation time on further development is shown. Phase C of germinal vesicle migration stage was identified as an optimum for successful stimulations. An interesting potential of successive stimulations leading to good quality spawns is established and the factors of success identified. The present work shows the  nterest of combined use of multivariate analyses and one way analyse of variance for the search of  links within aquaculture experiments results involving a diversity of causes and effects.
