Determining causes of osmotic stress in Pacific white shrimp postlarvae

This study evaluated the relationship between the molting stage, age and osmotic stress in Pacific white shrimp postlarvae. The results indicate that osmotic stress tests should be done only with at least PL12 at the intermolt stage and that were cultured at 35 ppt salinity and 29 degrees-C.

Salinity tolerance of Gulf corvina, prospective aquaculture species

After six weeks of experimental culture, comparable growth and survival were recorded in juvenile Gulf corvina raised at salinities of 5, 15, 25 or 35 ppt. Coupled with stable plasma osmolality values observed in fish at the varied salinities, these results confirmed the euryhaline nature of this species, a trait that could enhance its status as a candidate for aquaculture.
