Effect of varying crude protein levels on spawning frequency and growth of Sarotherodon niloticus breeders
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
Four-month-old S. niloticus breeders were fed with dry pellets containing 20-50% crude protein and the frequency of spawning involving removal of egg from the mouthbrooding females and growth were determined. When the diets ...
Relationship between diet composition and growth rate of the zoeal and mysis stages of Penaeus japonicus Bate
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Diets containing Chaetoceros gracilis plus Artemia nauplii artificially prepared diet, Diet-B, and two commercial feeds Tapes and mysid meals, were fed to larvae of P. japonicus. Highest survival rate was obtained when ...
A preliminary study on the protein requirement of Chanos chanos (Forskal) fry in a controlled environment
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Growth rate of fish appeared to be related to the levels of the protein in the diet up to 40%. Fish fed diets containing 50 and 60% grew slower than those fed 40%, and the optimum level appears to be 40% when fed to fry ...
A preliminary study on the use of the local variety of ipil-ipil Leucaena leucocephala as a protein source for prawn feed
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
A study was carried out to determine the effect of 10 or 20% leaves or seeds in the diet of Penaeus monodon , and the extent to which local ipil-ipil (Leucaena leucocephala ) could replace head shrimp meal. A brief description ...
Preliminary studies on growth and survival of Penaeus japonicus postlarvae fed with Tapes and commercial formula feeds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Growth and survival of P. japonicus postlarvae was studied using Tapes philippinarum and commercial formula feeds. After a 28-day feeding period, the highest survival rate of 100% was obtained in prawns receiving Diet-B, ...
A preliminary study on the evaluation of casein, shrimp meal, squid meal and spirulina as protein sources for Penaeus monodon (Fabricius) postlarvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
P. monodon postlarvae were fed with fresh brown mussel (Modiolus metcalfei) meat, and artificial diets containing casein, shrimp (Metapenaeus ensis) meal, squid (Loligo) meal, and Spirulina as protein sources at a rate of ...
Growth and survival of Penaeus monodon postlarvae fed shrimp head meal and fish meal as primary animal source of protein
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Although shrimp head meal alone does not provide for good growth and survival, fish meal can provide high survival rate. The addition of shrimp head improves this diet. It is suggested that cholesterol present in shrimp ...
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 ...
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.
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 ...
