Abstract:
... Difficulties in controlling settlement densities of hatchery-produced Pecten fumatus larvae on mesh-filled collector bags prompted an evaluation of two alternative nursery-rearing protocols. In both cases, larvae were initially settled and on-grown on mesh downweller screens in the hatchery. In the first protocol, spat were retained on conventional downweller screens until it is large enough to be ...

GIFT had been selected for increased body weight. Nile tilapia began to die when the water temperature dropped to 11 degrees C, and 100% mortality had occurred by 7.4 degrees C. Low lethal temperature ranged from 11 to ...

Abstract:
... In New Caledonia, the "syndrome 93," which results in mass mortalities of farmed shrimp Penaeus stylirostris, occurs during the transitional and the cold seasons. The transitional season is characterized by an important fall in the average water temperature from 28 to 19 degrees C in 2 weeks. Besides this marked temperature fall, there are also nyctemeral temperature changes of up to 7 degrees C i ...
