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 ...

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 ...

A statistical index of growth condition in an aquaculture experiment
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
A simple statistical index, for evaluating the condition of growth in an aquaculture experiment and indicating the extent of effect of any plausible rival hypothesis, is presented.

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 ...

Polyculture of milkfish (Chanos chanos) and mud crab (Scylla serrata) at two stocking densities
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Mud crabs (Scylla serrata) were cultured singly and in combination with milkfish (Chanos chanos) to compare growth, survival and production rates. Net production of crab was higher in polyculture than monoculture, but the ...
