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)
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 ...
Studies on the egg quality of Penaeus monodon Fabricius based on morphology and hatching rates
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Eggs of P. monodon are classified into 5 different types on the basis of morphological criteria and hatching rates: A<sub>1</sub> eggs, which undergo normal development with 58% hatching rate; A<sub>2</sub> eggs, which ...
Effect of substrate types on fecundity and nauplii production of ablated Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Experiments were undertaken to assess the survival, spawning, fecundity and nauplii production of ablated P. monodon females reared in flow-through broodstock tanks with white coralline and black sand substrate for 62 days. ...
Attractants in purified diets
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Juvenile Penaeus monodon were reared on purified diets containing different attractants used to gelatinize the cornstarch: plain water, shrimp, mussel, squid or trash fish extract. The highest survival rate was observed ...
Preserved algae as food for Penaeus monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Uni-algal cultures of C. calcitrans, S. costatum, T. chui and Isochrysis sp. obtained from the laboratory were harvested. The harvest, preserved by either freezing or sun-drying, was fed to the larvae of P. monodon . Among ...
Transport of sugpo, Penaeus monodon juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
A suctorean parasite of Penaeus monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
A new disease caused by a suctorean has been observed in tank-spawned and reared P. monodon larvae. Identification of the etiologic agent pointed to Ephelota gemmipara R. Hertwig, a species commonly found to inhabit hydroid ...
