Effects of increased stocking density and supplemental feeding on the production of milkfish fingerlings
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)Experiments were conducted to determine the effects of increased stocking density and supplemental feeding on survival and growth of milkfish (Chanos chanos) fry to fingerling stage and also to evaluate the profitability ... -
In vitro effects of fungicides on the fungus Haliphthoros philippinensis
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)Pure cultures of Haliphthoros philippinensis, isolated from infected Penaeus monodon larvae, were exposed for 24 hours to varying concentrations of antifungal agents. The efficiency of each agent to inhibit sporulation and ... -
Fry to fingerling production of Tilapia nilotica in aquaria using phytoplankton as natural feed
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)Overall results of the study indicate that the availability of high concentrations of phyloplankton in the rearing medium favoured growth of T. nilotica fry to fingerling. -
Culture of the mud crab, Scylla serrata (Forskal) at different stocking densities in brackishwater ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)The mean weight percentage survival, relative growth increment, net production and feed conversion value of S. serrata stocked in monoculture at different stocking densities are presented. -
Survival, growth and production of Penaeus monodon and P. indicus at different density combinations with milkfish
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)Penaeus monodon and P. indicus juveniles were stocked and reared for about 3 months in earthen ponds at different density combinations with Chanos chanos. The presence of either Penaeus species at any density ratio did not ... -
Improvement of diet attractability for Penaeus monodon by supplementing various attractants
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)An experiment was undertaken to test the effect of supplemental krill meal, earthworm meal, glycine, sucrose or mussel water on diet attractibility of Penaeus monodon. Only glycine or mussel water significantly improved ... -
Polyculture of milkfish (Chanos chanos) and mud crab (Scylla serrata) at two stocking densities
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)Mud crabs (Scylla serrata) were cultured singly and in combination with milkfish (Chanos chanos) to compare growth, survival and production rates. Net production of crab was higher in polyculture than monoculture, but the ... -
Survival, growth and production of Penaeus monodon at different stocking densities in earthen ponds with flow-through system and supplementary feeding
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)The survival, growth and production of Penaeus monodon in earthen ponds were observed. A significant effect of stocking density on the survival rate of prawns was observed. The final average weight obtained varied inversly ... -
Growth and survival rates of hatchery-produced and wild milkfish fry grown to fingerling size in earthen nursery ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)Growth and survival rates of hatchery-produced and wild milkfish (Chanos chanos) fry grown to fingerling size were compared. Data show no significant difference between the 2 fry. At a recommended stocking density of 30 ... -
A comparison between the catching efficiency of two milkfish fry collecting gears and their respective modifications
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)An experiment was conducted along the shore of Culasi, Antique in Panay to compare the milkfry (Chanos chanos) catching efficiency of the ordinary fry seine against its innovation and the ordinary sweeper against its 2 ... -
In-vitro effect of fungicides on hyphal growth and sporogenesis of Lagenidium sp. isolated from Penaeus monodon larvae and Scylla serrata eggs
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)The sensitivity of Lagenidium, isolated from Penaeus monodon, Scylla serrata , to 34 antimycotics was determined. Effects on the development of vesicles, zoospores and mycelial growth were evaluated. Although mycoidal ... -
Preliminary studies on the holding of live mussels after harvest
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)Green mussel (Perna viridis) were harvested to study the applicability of chilling to keep the mussels alive for a longer period of time and to review existing methods of packaging and transport. Data obtained from preliminary ... -
Feeding behavior and food preference of Penaeus monodon Fabricius with scrap tilapia
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)The time of day during which P. monodon feeds at different depth levels in earthen ponds, and its preference for three types of tilapia feeds (dry, fresh and fermented) were determined. It was observed that P. monodon ... -
Effects of water movement and aeration system on the survival and growth of hatchery bred sugpo (Penaeus monodon Fabricius) in earthen nursery ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)An experiment was conducted to determine the effects of water movement and airlift aeration on the survival and growth of P. monodon fry reared from P4P5 to P32P33 in earthen ... -
Polyculture of milkfish (Chanos chanos) and tiger prawn (Penaeus monodon Fab.) with and without supplemental feeding
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)Twelve 1,000 m2 earthen ponds were used to compare the growth rates, survival and production of milkfish (Chanos chanos) and prawn (Penaeus monodon) in monoculture and polyculture systems in shallow brackishwater ... -
Growth and survival of Penaeus monodon Fabricius zoeae on different diatom feeds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)A study was undertaken to determine the most suitable food for Penaeus monodon zoea out of mixed diatoms, Skeletonema costatum, Chaetoceros calcitrans and C. gracilis. Results indicate that mixed diatoms and C. gracilis ... -
