Mortalities of pond-cultured juvenile shrimp, Penaeus monodon, associated with dominance of luminescent vibrios in the rearing environment
(Elsevier, 1998)
Severe mortalities due to luminescent vibrios occurred in pond-cultured Penaeus monodon juveniles particularly in the first 45 days of culture. Luminescent vibriosis epizootics led to reduced shrimp production due to ...
A survey of chemical and biological products used in intensive prawn farms in the Philippines
(Elsevier, 1993)
With attractive prawn export prices and the availability of hatchery fry and commercial feeds, Philippine aquaculture has experienced a shift from milkfish to prawn Penaeus monodon and an intensification from traditional ...
Effect of dietary astaxanthin and vitamin A on the reproductive performance of Penaeus monodon broodstock
(Cambridge University Press, 1998)
The reproductive performance of pond tiger shrimp given astaxanthin (100 mg·kg<sup>−1</sup>) and/or vitamin A (20 000 IU·kg<sup>−1</sup>) for 61 d in tanks was assessed in a 2 × 2 factorial experiment in a completely ...
Bacterial diseases in shrimp (Penaeus monodon) culture in the Philippines
(Japanese Society of Fish Pathology, 1998)
The hatchery system for Penaeus monodon evolved from the Japanese community culture system to the modified Galveston method and this shift in culture technique triggered the outbreak of diseases due to opportunistic bacteria. ...
Year-round sexual maturation of bighead carp Aristichthys nobilis (Richardson) reared in floating cages in Laguna de Bay (Philippines).
(Blackwell Publishing, 1990)
Sexual maturation in bighead carp Aristichthys nobilis reared without supplemental feeding in floating cages in Laguna de Bay was observed year-round. Percent maturation ranged from 3 to 94% in females and 0 to 82% in males ...
