Acute toxicity of un ionized ammonia to milkfish (Chanos chanos) fingerlings
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
The acute toxicity of un-ionized ammonia to milkfish (Chanos chanos) fingerlings was determined using a static bioassay system. Median lethal concentrations found show that milkfish fingerlings have a high tolerance to ...
Effects of 2-phenoxy ethanol and MS-222 on milkfish fingerlings (Chanos chanos) as anaesthetic agents
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
An experiment was undertaken in order to determine an adequate anaesthetic and optimum concentrations for use in the handling of fingerling milkfish (Chanos chanos). The compounds 2-phenoxy ethanol and MS-222 were investigated. ...
Preliminary trials in Artemia rearing and salt production in earthen salt ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
The authors report on the production of Artemia obtained on a 0.5 ha pilot project with combined trials in Artemia rearing with solar salt production during the dry seasons and with production of milkfish (Chanos chanos) ...
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 ...
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)
Effects of increased stocking density and supplemental feeding on the production of milkfish fingerlings
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
Experiments were conducted to determine the effects of increased stocking density and supplemental feeding on survival and growth of milkfish (Chanos chanos) fry to fingerling stage and also to evaluate the profitability ...
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 ...
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 ...
Polyculture of milkfish (Chanos chanos) and mud crab (Scylla serrata) at two stocking densities
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Mud crabs (Scylla serrata) were cultured singly and in combination with milkfish (Chanos chanos) to compare growth, survival and production rates. Net production of crab was higher in polyculture than monoculture, but the ...
