Survival rates of different postlarval stages of Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
The objective of this study is to determine survival rates of different postlarval stages upon stocking in the Leganes ponds. Twelve 3m x 2m x 2m suspension nets made of nylon cloth (mesh size = 0.1 mm) were set up in a ...
Effect of nitrite, ammonia, and temperature on P. monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
P. monodon larvae were studied for the effects of temperature, ammonia, and nitrite on survival. Toxicity levels of nitrite were found to vary with larval stage. Larvae could tolerate ammonia up to about 10 ppm, with the ...
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 ...
Mass production of Penaeus monodon Fabricius juveniles in earthen nursery ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
Different culture techniques were tried for rearing larvae of Penaeus monodon , in order to obtain preliminary data on stocking density, water management, fertilization versus feeding and effect of different types of ...
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 ...
Viability of Penaeus monodon eggs after simulated transport conditions
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
P. monodon spawners, transported from maturation pens suffer from stress which in turn may lead to lowered spawning rate or fertility. Spawning the females in the maturation site and transporting the eggs to the hatchery ...
Growth and survival of Penaeus monodon postlarvae fed shrimp head meal and fish meal as primary animal source of protein
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Although shrimp head meal alone does not provide for good growth and survival, fish meal can provide high survival rate. The addition of shrimp head improves this diet. It is suggested that cholesterol present in shrimp ...
Organic pollution in culture water resulting from excess feed and metabolite buildup
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Penaeus monodon postlarvae were subjected to increasing feed concentrations and their growth and survival rates were recorded. Measurements were made of dissolved organic matter, and ammonia and nitrite-nitrogen concentrations. ...
