Maturation, reproduction, and broodstock technology
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1988)
Following a review of first maturation in Penaeus monodon , details are given of endocrine, nutritional and environmental methods of induced maturation used in aquaculture. Broodstock constitution and maintenance operations ...
Induced spawning and larval rearing of grouper (Epinephelus salmoides Maxwell)
(Asian Fisheries Society, 1986)
Broodfish of grouper (Epinephelus salmoides ) were induced to spawn by hormonal induction. The hormones used for this experiment were HCG + pituitary gland (PG) and LRH-a. The results showed that at dosages of 500 IU HCG ...
Problems associated with hormonal induction of gonad development in milkfish (Chanos chanos)
(Hong Kong University Press, 1985)
Recent developments in milkfish breeeding include succesful induced spawning of wild<sup>1,2</sup> and captive<sup>3-5</sup> fish and spontaneous spawning of broodstock.<sup>6</sup> Gravid spawners, however, are available ...
Releasing hormones as an effective agent in the induction of spawning in captivity of sea bass (Lates calcarifer)
(Australian Centre for International Agricultural Research, 1987)
A study was conducted to evaluate the effectiveness of luteinising-hormone releasing hormones in the induction of spawning of Lates calcarifer using different administration techniques: pellet implantation, Chinese analogue ...
Studies on broodstock of sugpo Penaeus monodon Fabricius and other penaeids at the SEAFDEC Aquaculture Department
(Cochin, India: The Marine Biological Association of India, 1982)
For hatchery production of Penaeus monodon and other penaeid fry, the SEAFDEC Aquaculture Department is dependent mainly on captive broodstock in the form of ablated females, using up to 1,500 spawners in one year. The ...

Broodfish of grouper (Epinephelus salmoides ) were induced to spawn by hormonal induction. The hormones used for this experiment were HCG + pituitary gland (PG) and LRH-a. The results showed that at dosages of 500 IU HCG ...
Milkfish culture and artificial propagation
(Marine Science Research Laboratory, Memorial University of Newfoundland, 1987)
Milkfish (Chanos chanos Forsskal) is widely distributed in the Indo-Pacific region and one of the most extensively cultured fish in Southeast Asia. In the Philippines, Indonesia and Taiwan, over 400,000 hectares of ...
Survival, maturation, fecundity and hatching rates of unablated and ablated Penaeus indicus H.M. Edwards from brackishwater ponds
(The Marine Biological Association of India, 1982)
Penaeus indicus H. M. Edwards harvested after three months of rearing in brackishwater ponds and averaging 6.9 g for females and 5.6 g for males were stocked in two 12 cu m flowthrough ferrocement tanks at 240 females and ...
Induced maturation in ablated Penaeus notialis and Penaeus schmitti
(Asian Fisheries Society, 1986)
Wild Penaeus notialis and P. schmitti were induced to mature by unilateral eyestalk ablation of females in 0.5, 1.6 and 2.0-m super(3) tanks stocked at 9-12 shrimps/m super(3). A total of 71 spawns was obtained from 80 P. ...
Induced maturation and spawning of milkfish, Chanos chanos Forsskal, by hormone implantation
(Elsevier, 1986)
The milkfish, Chanos chanos Forsskal, does not reach gonadal maturity easily in captivity. In an attempt to induce maturation, exogenous hormones, LHRH-A and 17α-methyl-testosterone, were implanted into adult milkfish ...
