Induction to ovary maturation by ablation in the pink shrimp Penaeus notialis
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
A partial unilateral ablation was carried out on immature females of the pink shrimp Penaeus notialis. They were maintained in 1,600 ℓ asbestos-cement tanks together with apparently mature males, not submitted to ...
Effect of various levels of squid protein on growth and some biochemical parameters of Penaeus japonicus juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
An unknown growth factor previously suspected in squid meal was found in the protein fraction of squid (Loligo vulgaris). It is clearly different from hydro-alcohol-soluble feed attractants that are also present in squid ...
Variation in tissue lipid content and fatty acid composition during ovarian maturation of unablated and ablated Penaeus monodon broodstock
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The tissue lipid content and fatty acid composition in the hepatopancreas, tail muscle and gonad of unablated and ablated Penaeus monodon were determined. Females at various stages of maturity were collected from offshore ...
Observations on the nauplii production from wild, cultivated and mixed populations of the blue shrimp (Penaeus stylirostris)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Due to low nauplii production from cultivated broodstock and to minimize dependence on wild stock, an experiment was run in which four treatments, consisting of combinations of 400 adult blue shrimp (Penaeus stylirostris) ...
The response of Penaeus monodon juveniles to varying protein/energy ratios in test diets
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The response of Penaeus monodon juveniles (0.71±0.11 g) to varying protein/energy ratios in test diets was determined. Purified diets consisting of different levels of protein, lipid and carbohydrates were formulated. Two ...
Factors affecting maturation and spawning of Penaeus esculentus in the laboratory
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Adult tiger prawns Penaeus esculentus were held in laboratory tanks under varying conditions of tank size, density, temperature and photoperiod for assessment of ovarian maturation and spawning. Both eyestalk ablated and ...
Heterotrophic bacteria associated with eggs and larvae of Penaeus indicus in a hatchery system
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Total viable aerobic heterotrophic bacteria (THB) associated with egg, nauplius, zoea, mysis and postlarva of Penaeus indicus and seawater in a hatchery system were estimated for three years from 1981 to 1984. The bacterial ...
A new approach in intensive nursery rearing of penaeids
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The need for a nursery phase between the hatchery and the growing pond to avoid mortalities of young postlarvae, and provide a better assessment of stocked animals is general in crustacean aquaculture.
The Centre ...
Culture of blue shrimp, Penaeus stylirostris in Sonora, Mexico
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The Centro de Investigaciones Cientificas y Tecnologicas de la Universidad de Sonora has been conducting research on the culture of the blue shrimp Penaeus stylirostris since 1972. Most of the programs carried out are ...
Water quality criteria for farming the grass shrimp, Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Physiological and growth effects of pH, salinity, temperature, heavy metals, pesticides and others on juvenile grass shrimp Penaeus monodon have been investigated to
determine the biologically safe concentrations. Optimal ...
