Endocrine changes associated with overripening of ovulated eggs in goldfish, Carassius auratus L.
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Changes in steroid hormone levels in the serum and ovarian fluid were studied during overripening in goldfish. Ovulated eggs retained in the ovarian cavity become overripe at around 12 h after ovulation and completely ...
A review of grouper (Epinephelus suillus) fry production research in Malaysia

Research on grouper (Epinephelus suillus) fry production in captivity has been carried out in Malaysia since 1986 at Tanjung Demong Marine Finfish Production and Research Centre (TDMFPRC) but the breakthrough was only ...
LHRHa and pimozide-induced breeding in the catfish, Clarias macrocephalus (Gunther)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Clarias macrocephalus is endemic yet dwindling freshwater foodfish in the Philippines. Induced breeding protocol was developed by monitoring the size and maturation of eggs at 0-48 h after a simultaneous injection of ...
Effects of different fat sources on the egg quality of grouper, Epinephelus suillus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
The effect of different fat sources on the egg quality of grouper, Epinephelus suillus eggs was evaluated. Fish in three tanks, each containing 3 females and 1 male, were fed various types of feeds namely: trash fish ...

Control of gonad growth, maturation and spawning in teleost fish: A review
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Despite their great variety of reproductive strategies, a general characteristic of most teleosts is that (where known) natural reproduction shows a long-term periodicity, even in tropical habitats (e.g. see contributions ...
The role of cyclic amp in oocyte maturation of goldfish, Carassius auratus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
The role of cyclic AMP in oocyte maturation was investigated using denuded goldfish oocytes cultured in vitro. The oocytes were stimulated with a maturation-inducing steroid (MIS), 17α, 20ß dihydroxy-4-pregnen-3-one (17, ...
