| Abstract |
Three shrimp species, Penaeus monodon, P. stylirostris (Panama and Mexican strains) and P. vannamei have matured and spawned in captivity at the Centre Océanologique du Pacifique (COP) laboratory. The shrimp, originally stocked as juveniles or postlarvae, were reared to adult size in tanks and ponds and have completed the cycle: F3 generation for P. monodon, F2 for P. stylirostris (Panama strain) and P. vannamei and F1 for P. stylirostris (Mexican strain). Maturation occurs naturally under our rearing conditions or is induced by unilateral eyestalk ablation. Details are given on mating behavior, ovarian development, number of spawnings, egg viability and maintenance of captive brood stock. Partial results so far obtained for P. monodon and P. stylirostris clearly show a reared brood stock could sustain a commercial hatchery. [NOT CONTROLLED OCR] |
