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. ...
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 ...
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 ...
Ferrocement buoys for mussel culture
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
A method is described for culturing mussels (Mytilus smaragdinus) using ferro-cement buoys, which may be used in the construction of a raft house or a flotation system for nets and cages.
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 ...
Growth and survival rates of hatchery-produced and wild milkfish fry grown to fingerling size in earthen nursery ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Growth and survival rates of hatchery-produced and wild milkfish (Chanos chanos) fry grown to fingerling size were compared. Data show no significant difference between the 2 fry. At a recommended stocking density of 30 ...
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)
