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 ...
Identification of the postlarval Penaeus (Crustacea, Decapoda, Penaeidae) appearing along shore waters
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Diagnostic characters for the identification of postlarval Penaeus appearing along the coastal waters of the Philippines are reviewed and categorized, based on materials from the wild and laboratory. Presently there are 7 ...
Effects of water movement and aeration system on the survival and growth of hatchery bred sugpo (Penaeus monodon Fabricius) in earthen nursery ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
An experiment was conducted to determine the effects of water movement and airlift aeration on the survival and growth of P. monodon fry reared from P<sub>4</sub>P<sub>5</sub> to P<sub>32</sub>P<sub>33</sub> in earthen ...
Polyculture of milkfish (Chanos chanos) and tiger prawn (Penaeus monodon Fab.) with and without supplemental feeding
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Twelve 1,000 m<sup>2</sup> earthen ponds were used to compare the growth rates, survival and production of milkfish (Chanos chanos) and prawn (Penaeus monodon) in monoculture and polyculture systems in shallow brackishwater ...
Feeding behavior and food preference of Penaeus monodon Fabricius with scrap tilapia
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
The time of day during which P. monodon feeds at different depth levels in earthen ponds, and its preference for three types of tilapia feeds (dry, fresh and fermented) were determined. It was observed that P. monodon ...
In-vitro effect of fungicides on hyphal growth and sporogenesis of Lagenidium sp. isolated from Penaeus monodon larvae and Scylla serrata eggs
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
The sensitivity of Lagenidium, isolated from Penaeus monodon, Scylla serrata , to 34 antimycotics was determined. Effects on the development of vesicles, zoospores and mycelial growth were evaluated. Although mycoidal ...
Survival, growth and production of Penaeus monodon at different stocking densities in earthen ponds with flow-through system and supplementary feeding
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
The survival, growth and production of Penaeus monodon in earthen ponds were observed. A significant effect of stocking density on the survival rate of prawns was observed. The final average weight obtained varied inversly ...
