A preliminary study on the use of the local variety of ipil-ipil Leucaena leucocephala as a protein source for prawn feed
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
A study was carried out to determine the effect of 10 or 20% leaves or seeds in the diet of Penaeus monodon , and the extent to which local ipil-ipil (Leucaena leucocephala ) could replace head shrimp meal. A brief description ...
Laboratory breeding of the mud crab Scylla serrata (Forskal) through the zoea and megalopa stages to the crab stage
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
A series of experiments is being conducted to establish breeding techniques to mass-produce seedlings of S. serrata for pond cultivation to meet the commercial demand for the crab. The objective is to culture the crab ...
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 ...
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 ...
Effect of furanace on the development of larval stages of Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Zoea 2 (Z<sub>2</sub>), Mysis 1 (M<sub>1</sub>) and Postlarva 1 (P<sub>1</sub>) of P. monodon artificially spawned in closed-system concrete hatchery tanks were bioassayed for their tolerance to the antibiotic furanace. ...
The water stability of shrimp diets with various polysaccharides as a binding agent
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
The water stability of shrimp (Penaeus monodon) diets with various polysaccharides as binding agents were tested without steaming. The diet with alginate showed the best water stability and did not completely disintegrate ...
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 ...
Dietary crude protein requirement of Tilapia nilotica fry
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
To determine growth and survival of Tilapia nilotica fry fed formulated practical dry diets with varying crude protein levels, fish were subjected to 3 seperate feeding trials. Isocaloric practical diets containing 20, 25, ...
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.
Fishwater and agar as binders in a prawn diet
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
The objectives of the study were to find out the proportion of water to fish fins, skin and bones that would give a good gel and to determine the effect of a combination of fish water and commercial crude agar on the water ...
