Growth and survival of Penaeus monodon Fabricius zoeae on different diatom feeds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
A study was undertaken to determine the most suitable food for Penaeus monodon zoea out of mixed diatoms, Skeletonema costatum, Chaetoceros calcitrans and C. gracilis. Results indicate that mixed diatoms and C. gracilis ...
Growth phases of cultured algae used as larval food
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
A study was undertaken to determine the onset and duration of the growth phases of cultured algae commonly used as larval food (Skeletonema costatum, Chaetoceros calcitrans, Tetraselmis chuii, Chlorella vulgaris, Isochrysis ...
Developmental and ecological stages in the life history of milkfish Chanos chanos Forsskal
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Seven stages in the life history of the milkfish C. chanos , are recognized and suggested: A, embryonic; B, yolksac larval; C, larval; D, postlarval; E, juvenile; F, subadult; G. adult. An outline is presented of the life ...
A comparative study of various extenders of milkfish, Chanos chanos (Forsskal) sperm preservation
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Four chemical extenders in 7 different concentrations (potassium chloride, sodium chloride, glucose, sodium citrate, Ringer s solution, cow serum and milkfish (Chanos chanos) serum) were compared in the preservation of ...
Studies on the egg quality of Penaeus monodon Fabricius based on morphology and hatching rates
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Eggs of P. monodon are classified into 5 different types on the basis of morphological criteria and hatching rates: A<sub>1</sub> eggs, which undergo normal development with 58% hatching rate; A<sub>2</sub> eggs, which ...
A statistical index of growth condition in an aquaculture experiment
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
A simple statistical index, for evaluating the condition of growth in an aquaculture experiment and indicating the extent of effect of any plausible rival hypothesis, is presented.
Effect of substrate types on fecundity and nauplii production of ablated Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Experiments were undertaken to assess the survival, spawning, fecundity and nauplii production of ablated P. monodon females reared in flow-through broodstock tanks with white coralline and black sand substrate for 62 days. ...
Culture experiments on the copepod, Tisbintra elongata MORI, and evaluation of that species as food organism for milkfish larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
Five types of food were used to culture T. elongata: rice bran, cow dung, bread, cow dung, bread yeast, fermented fish solubles and Spirulina. Bread yeast was found to give the highest densities. An evaluation was also ...
Attractants in purified diets
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Juvenile Penaeus monodon were reared on purified diets containing different attractants used to gelatinize the cornstarch: plain water, shrimp, mussel, squid or trash fish extract. The highest survival rate was observed ...
Diel fluctuations in catch of the postlarval Penaeus japonicus group
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
Experiments were undertaken in order to measure the diel fluctuations in the catch of the post-larvae of P. japonicus in relation to the tidal cycles, light conditions and water temperature. The fluctuations are discussed ...
