Methods of harvesting and preservation of the diatom Chaetoceros calcitrans
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Diatom culture and larval feeding experiments were conducted to test the viability and acceptability of preserved algal concentrates. C. calcitrans is characterised by the presence of setae which keep them suspended in ...
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 ...
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 ...
Laboratory breeding of the mud crab Scylla serrata (Forskal) through the zoea and megalopa stages to the crab stage
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
A series of experiments is being conducted to establish breeding techniques to mass-produce seedlings of S. serrata for pond cultivation to meet the commercial demand for the crab. The objective is to culture the crab ...
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 ...
The effect of various salinity levels and stocking density manipulation methods on the survival of milkfish fry (Chanos chanos Forsskal) during storage
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
Results of the study indicate that the survival rate and increase in body weight did not differ significantly at different salinity levels or at different stocking density manipulation methods. A significant interaction ...
Optomotor reaction of milkfish larvae and juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
A simple method of tagging prawns
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
The recognition of individual animals is crucial to many aspects of research. Prawns (Penaeus monodon) present unique difficulties in this respect since they molt regularly. Thus, almost all tagging and marking methods ...
Toxicity of malachite green to the larvae of Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
A study was undertaken examining the effect of malachite green on the development and survival of the zoeae, mysis and post-larvae of Penaeus monodon. Sensitivity varied with the different larval stages; the zoeae appeared ...
