Notes on ovarian rematuration of ablated sugpo (prawn) Penaeus monodon Fabricius
Primavera, Jurgenne 
; (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
; (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 ...

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 ...

The effect of different binders on the water stability of feeds for prawn
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Corn starch, gelatin, sago palm starch, agar, and bread flour were tested for their binding capacity in pelleted diets for Penaeus monodon . Agar was found to be good binder, but it costs too much, while bread flour was ...

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 ...

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 ...

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
Primavera, Jurgenne ; (Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
; (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
; Primavera, Jurgenne ; (Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
; (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. ...

Culture experiments on the copepod, Tisbintra elongata MORI, and evaluation of that species as food organism for milkfish larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
Five types of food were used to culture T. elongata: rice bran, cow dung, bread, cow dung, bread yeast, fermented fish solubles and Spirulina. Bread yeast was found to give the highest densities. An evaluation was also ...
