(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)The elongation and shortening of the flounder fin rays during its metamorphosis may be parallel to the appearance and resorption of the tadpole tail during amphibian metamorphosis. The dorsal fin rays of the Japanese ... -
Role of growth hormone in the adaptation to sea water of juveline brown trout, (Salmo trutta)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)The first part of the study investigates the ability of ovine growth hormone (oGH) to enhance the hypo-osmoregulatory and growth performance of juvenile brown trout after exposure to sea water (SW). Three groups of fish ... -
Resistance of two Nile tilapia, Oreochromis niloticus (L.) strains exposed to a mixture of zinc, cadmium and inorganic mercury
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)Two strains of one month-old Oreochromis niloticus namely CLSU (obtained from Central Luzon State University, Philippines) and NIFI (from National Inland Fisheries Institute, Thailand) were exposed to a sublethal mixture ... -
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 ... -
Larviculture of milkfish (Chanos chanos) in outdoor tanks
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)In the past, larviculture of milkfish depended entirely on the use of rotifers and brine shrimp nauplii and rearing trials were done under roofed facilities. Since the dietary value of live food varies according to culture ... -
Review of SEAFDEC/AQD finfish seed production research
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)Research on seed production of several foodfishes has been a continuing activity of SEAFDEC/AQD since 1976. Fry and juvenile production methods of these fish commodities are in various stages of advancement. For instance, ... -
A review of grouper (Epinephelus suillus) fry production research in Malaysia
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)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 ... -
