In vitro effects of fungicides on the fungus Haliphthoros philippinensis
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
Pure cultures of Haliphthoros philippinensis, isolated from infected Penaeus monodon larvae, were exposed for 24 hours to varying concentrations of antifungal agents. The efficiency of each agent to inhibit sporulation and ...
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 ...
A simple method of tagging prawns
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
The recognition of individual animals is crucial to many aspects of research. Prawns (Penaeus monodon) present unique difficulties in this respect since they molt regularly. Thus, almost all tagging and marking methods ...
Toxicity of malachite green to the larvae of Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
A study was undertaken examining the effect of malachite green on the development and survival of the zoeae, mysis and post-larvae of Penaeus monodon. Sensitivity varied with the different larval stages; the zoeae appeared ...
Survival rate of Penaeus monodon Fabricius larvae fed Chaetoceros sp. and bread yeast
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
An evaluation was made of the effects of Chaetoceros species, bread yeast and their combination on the survival of Penaeus monodon larvae. In general it was found that feeding with a combination of the 2 resulted in higher ...
Effect of different sex ratios of ablated wild-stock Penaeus monodon Fabricius on maturation, fecundity and hatching rates
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
Observations on the artificial fertilization of eggs and larval rearing of the grey mullet, Mugil cephalus L.
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
The results are presented of attempts to artificially fertilize Mugil cephalus eggs in the Philippines. Embryonic development is outlined and rearing of the larvae described. Mass mortality occurred during week 3 of rearing.
Survival, maturation, fecundity and hatching rates of unablated and ablated Penaeus indicus H.M. Edwards from brackishwater ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
Penaeus indicus harvested after three months of rearing in brackishwater ponds and averaging 6.9 g for females and 5.6 g for males were stocked in two 12 cu m flowthrough ferrocement tanks at 240 females and 200 males per ...
Ipil-ipil (Leucaena leucocephala) leaves as a plant protein source in prawn diets
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Penaeus monodon juveniles were fed diets containing fish meal, shrimp head meal and ipil-ipil leaves soaked and unsoaked, local and peruvian varieties. Mean weight gain at the end of 8 wk was significantly highest among ...
