Effect of temperature and salinity on the hatching of eggs and larval development of sugpo, Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Incubation of Penaeus monodon eggs and rearing of different larval stages were undertaken at nine temperature-salinity combinations. The eggs, nauplii, zoea and mysis from one spawner kept as stock culture at ambient ... -
Effect of various levels of squid protein on growth and some biochemical parameters of Penaeus japonicus juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)An unknown growth factor previously suspected in squid meal was found in the protein fraction of squid (Loligo vulgaris). It is clearly different from hydro-alcohol-soluble feed attractants that are also present in squid ... -
Effects of CO2-induced ocean environmental changes on marine life: implications for aquaculture
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2011)The world's oceans are becoming warmer and acidic. The atmospheric carbon dioxide concentration has increased from 280 ppm at pre-industrial revolution to above 380 ppm today. The 4th IPCC report predicts that it will range ... -
Effects of diet on reproductive performance of ablated Penaeus monodon broodstock
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Four practical diets were compared for their effects upon ovarian maturation and spawning of ablated Penaeus monodon broodstock. Diets were formulated based upon the fatty acid profile of wild P. monodon. Diets 1 and 3 ... -
Effects of dietary carbohydrate, lipid and energy on the growth, feed efficiency, and tissue composition of bighead carp (Aristichthys nobilis) fry
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)The utilization of dietary carbohydrate and lipid as energy sources for bighead carp (Aristichthys nobilis) fry and various protein:energy ratios were investigated in a 2x3x3 factorial feeding experiment. Semi-purified ... -
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 ... -
The effects of manures and pelleted feeds on survival, growth and yield of Penaeus stylirostris and Penaeus vannamei in Panama
(Aquaculture Department, Southeast Asian Fisheries, Development Center, 1985)Brackishwater ponds (0.8 m deep and 600 m2) on the Pacific Coast of Panama were stocked at 5/m2 with post-larval shrimp (1 cm, 0.05 g) collected from the wild. Species composition at stocking was 56% Penaeus vannamei, 33% ... -
Effects of salinity on growth of young milkfish, Chanos chanos
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1976)Growth of young milkfish was studied at different levels of salinity over a period 68 days. Results suggested that young milkfish reared in freshwater or less saline sea water grew faster than in sea water. The increase ... -
Effects of single injection of carp pituitary extract and human chorionic gonadotropin on germinal vesicle migration and ovulation in lampan sungai, Puntius schwanenfeldii (Bleeker): A preliminary study
(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 ... -
Effects of some water-soluble vitamins on the growth of Penaeus monodon juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The response of Penaeus monodon juveniles (ave. wt.= 0.076 g) in terms of survival and growth rates to vitamin test diets was observed in a 35-day feeding experiment. The prawns were reared in 60-ℓ oval tanks containing ... -
The effects of stocking densities on growth and survival of Penaeus vannamei in cow manure-enriched ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Ecuadorian Penaeus vannamei were stocked in eight dirt ponds (approximately 163 m2) at four different types of density, i.e., 5 shrimp/m2, 10 shrimp/m2, 15 shrimp/m2, and 20 shrimp/m2. The initial body weight ranged between ... -
Efficacy of the inactivated nervous necrosis virus vaccine against viral nervous necrosis in pond-reared orange-spotted grouper Epinephelus coioides
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2021-12)The field efficacy of the formalin-inactivated nervous necrosis virus (NNV) against viral nervous necrosis (VNN) in orange-spotted grouper (Epinephelus coioides) reared in floating net cages in earthen pond was investigated. ... -
