(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
The effects of crude pituitary extract (CPE) and human chorionic gonadotropin (hCG) on germinal vesicle migration and ovulation in lampan sungai Puntius schwanenfeldii (Bleeker) were investigated. Sexually mature female ...
Artificial incubation for intensive fry production of Nile tilapia Oreochromis niloticus (L.)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Two experiments were conducted to evaluate and compare the production, quality, and survival of eggs and the subsequent growth and survival of fry in two small scale production systems: (i) natural incubation (NI), and ...

Wild-caught mangrove red snapper, Lutjanus argentimaculatus, reared for a year in 4.0 m diameter by 1.5 m deep circular concrete tank spontaneously matured and were used for induced spawning trials. On 19 August 1992, a ...
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 ...
Changes in lipid and fatty acid content during early larval development of milkfish (Chanos chanos): influence of broodstock diet
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
The influence of amount and type of lipid given to milkfish broodstock by developing larvae was investigated by feeding broodstock commercial diets that differed in lipid content and composition. The two commercial feeds ...
Impact of nickel poisoning on the histology of the ovaries of Oreochromis mossambicus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Ovaries of Oreochromis mossambicus exposed to sublethal concentrations of nickel sulphate (0.5 mg/1 and 1.0 mg/1) were histologically analyzed. Changes following exposure to 0.5 mg/1 nickel sulphate include irregularities ...
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, ...
Larviculture of milkfish (Chanos chanos) in outdoor tanks
