Preliminary biological evaluation of some formulated feeds for P. monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Rice bran is widely used by fish farmers as supplementary feed while soybean cake is used both as feed and as fertilizer in fishponds. Both fish meal and shrimp head have been found acceptable as feed ingredients. However, ...
The effect of various protein levels on the growth and survival rates of Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Postlarvae of tiger prawns, P. monodon , were fed with various protein levels of 0; 30; 40 and 50%, fish meal and rice bran were combined and pelletized for 16 wks. Prawns used had an average mean length of 1.2 mm and an ...
The food and feeding habit of Penaeus monodon Fabricius collected from Makato River, Aklan, Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
The food of Penaeus monodon collected from Makato R., from Sept 1977 to Jan 1978 is described with preliminary observations on its feeding habit and rate of foregut clearance. Feeding behaviour appears to be associated ...
Changes in length and weight of milkfish fry preserved in formalin
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Fry shrank immediately after they were preserved in formalin, but from the second week onwards shrinkage was almost nil. Fry in freshwater formalin solutions shrunk less than those in seawater formalin solutions. It is ...
Notes on the construction of 12 cu m ferrocement maturation tank for prawn broodstock
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Amino acid analysis of P. monodon muscle
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Figures for the amino acid composition of Penaeus monodon, are tabulated, and compared to those for white tuna meat.
Survival rates of different postlarval stages of Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
The objective of this study is to determine survival rates of different postlarval stages upon stocking in the Leganes ponds. Twelve 3m x 2m x 2m suspension nets made of nylon cloth (mesh size = 0.1 mm) were set up in a ...
Land-based mass production of prawn (Penaeus monodon Fabricius) spawners
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
The first spawnings were obtained 12 days after ablation with 4 spawners yielding 784,000 eggs and a harvest of 250,000 P<sub>10</sub> fry. Survival of females after 1 month was approximately 30%. Mortalities were mostly ...
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 different light intensities on the growth of the diatom Chaetoceros calcitrans
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Batch cultures of C. calcitrans were maintained indoors at a temperature range of 21 to 25 C and continuously illuminated by 40-watt daylight fluorescent lights. Cultures were exposed to 5 different intensities from 200 ...
