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. ...
Effects of exogenous hormone injections on milt consistency in newly caught, wild milkfish
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
A study was conducted to determine the effects of single injections of human chorionic gonadotropin (HCG) and Durandron Forte 250 on sperm motility, vitality and density and also on the consistency of milt in newly caught, ...
Fundamental study on the behavior of milkfish fry for the evaluation of the efficiency of traditional fry collecting gears in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
The response of Chanos chanos fry to moving and stationary nets of different mesh size and colour, underwater visibility of the nets and water filtration were studied. Results indicate that milkfish fry may be driven by ...
Effects of temperature on behavior, growth, development and survival of young milkfish, Chanos chanos Forsskal
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
The effects of 3 temperature treatments on activity, feeding, growth, development and survival of young milkfish (Chanos chanos) were investigated under laboratory conditions. It is believed that the results may be applied ...
Gill lesions associated with acute exposure to ammonia
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
Histopathological effects of ammonia on the gills of milkfish (Chanos chanos) fingerlings were examined qualitatively.
Evaluation of milkfish (Chanos chanos Forskal) and prawn (Penaeus monodon Fabricius) in polyculture systems
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
The growth, survival and profitability of C. chanos and P. monodon grown in 5 different combinations for 100 days in 500m<sup>2</sup> brackish water ponds were assessed. Differences in the growth and production of prawns ...
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 ...
A comparative study of various extenders of milkfish, Chanos chanos (Forsskal) sperm preservation
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Four chemical extenders in 7 different concentrations (potassium chloride, sodium chloride, glucose, sodium citrate, Ringer s solution, cow serum and milkfish (Chanos chanos) serum) were compared in the preservation of ...
Polyculture of milkfish (Chanos chanos) and tiger prawn (Penaeus monodon Fab.) with and without supplemental feeding
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Twelve 1,000 m<sup>2</sup> earthen ponds were used to compare the growth rates, survival and production of milkfish (Chanos chanos) and prawn (Penaeus monodon) in monoculture and polyculture systems in shallow brackishwater ...
