Effect of varying crude protein levels on spawning frequency and growth of Sarotherodon niloticus breeders
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
Four-month-old S. niloticus breeders were fed with dry pellets containing 20-50% crude protein and the frequency of spawning involving removal of egg from the mouthbrooding females and growth were determined. When the diets ...
Survival and changes in the fine structure of selected tissues of Penaeus monodon Fabricius juveniles fed various carbohydrates
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
Penaeus monodon juveniles were reared on semipurified diets containing various carbohydrates (maltose, sucrose, dextrin, molasses, cassava starch, corn starch or sago palm starch). Significant differences were observed ...
Gum arabic, carrageenan of various types and sago palm starch as binders in prawn diets
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
An experiment was undertaken in order to investigate the use of sago palm starch, gum arabic and carrageenans as binders in prawn diets. Water stability data are presented; EPT-2 carrageenan was found to be the best binder ...
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 ...
Preliminary studies on predicting the setting season of oysters for the benefit of shellfish farmers
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
Preliminary findings from a spatfall forecasting programme initiated in April 1981 at Himamaylan River, Negros Occidental are presented. Two main activities are involved: 1) monitoring of daily counts of oyster larvae in ...
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. ...
Experiment on larval rearing of Penaeus monodon fed with cultured diatom Chaetoceros calcitran and fermented vegetable trash
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
A brief account is given of experiments undertaken rearing Penaeus monodon larvae fed on diatom (Chaetoceros calcitran) and fermented vegetable trash, which included fruits and their peels, vegetables and rice. The possible ...
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 ovarian rematuration of ablated sugpo (prawn) Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
To what extent spent P. monodon females can remature and spawn successive broods is an important question in terms of recycling spawners in a commercially viable operation. Corollary to this is the quantity and quality of ...
Successful inoculation of Artemia and production of cysts in man-made salterns in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
The authors report on inoculation experiments of Artemia nauplii and young adults of the San Francisco Bay strains in earthen fish ponds. The test inoculated proved successful where water salinity ranges from 20 to 32 ...
