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, ...
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 ...
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 ...
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.
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) ...
Notes on the external sex characters of Chanos chanos Forskal spawners
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
In this study, the authors did not find any visible differences between the sexes with reference to external features such as coloration, shape of head, snout and operculum, presence of tubercles or nasal pores, length, ...
