Ferrocement buoys for mussel culture
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
A method is described for culturing mussels (Mytilus smaragdinus) using ferro-cement buoys, which may be used in the construction of a raft house or a flotation system for nets and cages.
Preserved algae as food for Penaeus monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Uni-algal cultures of C. calcitrans, S. costatum, T. chui and Isochrysis sp. obtained from the laboratory were harvested. The harvest, preserved by either freezing or sun-drying, was fed to the larvae of P. monodon . Among ...
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 ...
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 ...
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 ...
The effect of different binders on the water stability of feeds for prawn
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Corn starch, gelatin, sago palm starch, agar, and bread flour were tested for their binding capacity in pelleted diets for Penaeus monodon . Agar was found to be good binder, but it costs too much, while bread flour was ...
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)
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 ...
Courtship and mating behavior in Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
An illustrated description is given of the courtship and mating behaviour of P. monodon. Courtship and mating follow three distinct phases: (1) parallel swimming of male and female from the bottom to a height of 20-40 cm ...
