Abstract Share this page

Nine generations of breeders of Penaeus stylirostris were produced since the first post-larvae arrived in 1980. Breeders were raised in earthen ponds in a two-phase system: density was about 1/m2 until 20 g and less than 0.5/m2 afterwards. They were fed a compounded feed and squid was added once a week after one day of starvation. In such conditions, 60 g females and 50 g males were obtained within eight months. Maturation was induced in indoor tanks, with control of light and temperature, with a regular supplementation of fresh food and the use of unilateral eyestalk ablation. Density was 5 to 7/m2 with 1:1 sex ratio. Spawning indices were more than 3 spawns/female/month on a routine basis. Using artificial insemination, about 100 million nauplii were produced for the last three years from 2000 females. This technique has now allowed the start of commercial production of P. stylirostris, a non-indigenous species in New Caledonia.
