Studies on the egg quality of Penaeus monodon Fabricius, based on morphology and hatching rates
(Elsevier, 1981)
Eggs of Penaeus monodon are classified into five different types on the basis of morphological criteria and hatching rates — A1 eggs undergo normal development with 58% hatching rate; A2 eggs show delayed and/or abnormal ...
Current fish disease problems in the Philippines and their economic impact
(1987)
An account is given of fish disease problems facing the aquaculture industry in the Philippines. The Laguna de Bay fish kills that occurred in December 1985 and February 1986, involving epizootic ulcerative syndrome of ...
Effects of different sex ratios on maturation, fecundity and hatching rates of ablated Penaeus monodon wild stock
(Fisheries Research Society of the Philippines, 1980)
The minimum number of males per female that would still ensure high maturation, fecundity and hatching rates in Penaeus monodon broodstock, is determined. Wild stock P. monodon were stocked in 4 m diameter circular tanks ...
Selection, transport and acclimation of prawn fry
(U.P. Aquaculture Society, 1988)
The most important criterion among many used by operators for choosing poostlarvae to stock in ponvds, is the stage of development. THe stages considered suitable for stocking (about PL<sub>20</sub>) can be identified by ...
Effect of substrate types on fecundity and nauplii production of ablated Penaeus monodon Fabricius
(Science and Technology Information Institute, Department of Science and Technology, 1980)
The survival, spawning, fecundity, and nauplii production of ablated Penaeus monodon females reared in flow-through broodstock tanks with white coralline and black sand substrates for 62 days, were assessed. Prawns exposed ...
Development of broodstock for small-scale shrimp hatchery (with particular reference to Penaeus monodon)
(South China Sea Fisheries Development and Coordinating Programme, 1982)
To be self-sufficient in spawner/larval supply, a small-scale Penaeus monodon hatchery should have the following: 1) broodstock tanks or pens depending on location and other factors; 2) pond sources of broodstock of ...
