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 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 ...
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 ...
Growth and survival rates of hatchery-produced and wild milkfish fry grown to fingerling size in earthen nursery ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Growth and survival rates of hatchery-produced and wild milkfish (Chanos chanos) fry grown to fingerling size were compared. Data show no significant difference between the 2 fry. At a recommended stocking density of 30 ...
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, ...
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.
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 ...
