Effect of some physico-chemical factors on the survival and growth of Penaeus monodon postlarvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Growth and survival rates of P. monodon postlarvae were examined at different temperatures, salinities, and nitrite and ammonia concentrations, using one feed level. Condition of postlarvae greatly affected the experimental ...
Effect of nitrite, ammonia, and temperature on P. monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
P. monodon larvae were studied for the effects of temperature, ammonia, and nitrite on survival. Toxicity levels of nitrite were found to vary with larval stage. Larvae could tolerate ammonia up to about 10 ppm, with the ...
Laboratory breeding of the mud crab Scylla serrata (Forskal) through the zoea and megalopa stages to the crab stage
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
A series of experiments is being conducted to establish breeding techniques to mass-produce seedlings of S. serrata for pond cultivation to meet the commercial demand for the crab. The objective is to culture the crab ...
Isolation and culture in artificial media of Lagenidium from Penaeus monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Fungal infection of P. monodon larvae is a problem in hatchery operations. The fungus, which attacks the nauplius to postlarval stages and causes up to 100% mortality, has been tentatively identified as belonging to the ...
