Fundamental study on the behavior of milkfish fry for the evaluation of the efficiency of traditional fry collecting gears in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
The response of Chanos chanos fry to moving and stationary nets of different mesh size and colour, underwater visibility of the nets and water filtration were studied. Results indicate that milkfish fry may be driven by ...
Annual report 1979
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
The annual report for 1979 is presented. A summary of the centre's activities is given with particular emphasis on the milkfish, Chanos chanos, programme and the prawn programme. Administrative details are included.
Ipil-ipil (Leucaena leucocephala) leaves as a plant protein source in prawn diets
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Penaeus monodon juveniles were fed diets containing fish meal, shrimp head meal and ipil-ipil leaves soaked and unsoaked, local and peruvian varieties. Mean weight gain at the end of 8 wk was significantly highest among ...
Evaluation of milkfish (Chanos chanos Forskal) and prawn (Penaeus monodon Fabricius) in polyculture systems
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
The growth, survival and profitability of C. chanos and P. monodon grown in 5 different combinations for 100 days in 500m<sup>2</sup> brackish water ponds were assessed. Differences in the growth and production of prawns ...
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.
