Evaluation of artificial feeds for shrimp (Penaeus monodon) production in brackishwater ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The experiment was conducted in fifteen 500-m2 brackishwater ponds to determine the response of Penaeus monodon juveniles fed with various artificial diets. Five treatments with three replicates each were: two commercial ... -
Growth and productivity of juvenile banana prawns, Penaeus merguiensis in natural and laboratory systems
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Growth and survival of Penaeus merguiensis juveniles were measured over four years in the Norman River estuary, south-eastern Gulf of Carpentaria. Growth in carapace length for the first 8-9 weeks after settlement was ... -
A preliminary economic analysis for extensive and semi-intensive shrimp culture in South Carolina, U.S.A.
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)South Carolina has some 28,500 ha of impounded coastal wetlands. These impoundments are remnants of the rice culture industry of the 19th century and are now of interest for waterflow management and possibly aquaculture. ... -
Recruitment of postlarval penaeid prawns in the Vellar estuary, South India
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The northern bank of Vellar estuary (Parangipettai, India) is ideal for postlarval penaeid prawn recruitment. The annual recruitment, distribution and the substratum preference of postlarval immigrants at three different ... -
Induction to ovary maturation by ablation in the pink shrimp Penaeus notialis
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)A partial unilateral ablation was carried out on immature females of the pink shrimp Penaeus notialis. They were maintained in 1,600 ℓ asbestos-cement tanks together with apparently mature males, not submitted to ... -
Larval growth and survival optima for four species of penaeids from Australia, as indicated by their distribution and abundance in the field
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Prawn catches from tropical northern Australia are dominated by four species of prawns: Penaeus merguiensis, P. semisulcatus, P. esculentus and P. latisulcatus. Three of the species (P. merguiensis, P. semisulcatus and P. ... -
Study on the larval rearing of Penaeus merguiensis
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Nursing postlarvae of Penaeus merguiensis in the same tank as rearing always results in low survival rates, around 30%. One reason is that stocking density for P1 is too high for postlarvae grown to P20 size. Another reason ... -
The use of microencapsulated feeds to replace live food organisms in shrimp hatcheries
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)An adequate supply of hatchery produced shrimp fry is the major constraint to the intensification and growth of shrimp culture practices. If even 20% of the more than 500,000 ha of the world's existing tropical and ... -
Induced ovarian maturation and rematuration by eyestalk ablation of Penaeus monodon collected from Indian ocean (Phuket province) and Songkhla lake
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Because of the difficulty involved in maintaining a supply of sexually mature female shrimp for larval production in hatcheries, experiments on induced ovarian maturation in tiger shrimp, Penaeus monodon by eyestalk ablation ... -
Culture of blue shrimp, Penaeus stylirostris in Sonora, Mexico
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The Centro de Investigaciones Cientificas y Tecnologicas de la Universidad de Sonora has been conducting research on the culture of the blue shrimp Penaeus stylirostris since 1972. Most of the programs carried out are ... -
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 ... -
Ruppia maritima and Najas graminea as natural foods for Penaeus monodon juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Ruppia maritima (kusay-kusay, Hiligaynon) and Najas graminea (digman, Hiligaynon) are macrophytes growing in local brackishwater ponds believed to provide food and shelter to prawns and fishes. Their effect on growth and ... -
Lecithin requirement of Penaeus monodon juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)An 8-week feeding experiment was carried out to determine the lecithin requirement of Penaeus monodon postlarvae. Six shrimps with initial mean weight of 0.11 g were stocked in oval fiberglass tanks in a flowthrough system ... -
Diseases, parasites, commensals and fouling of commercial Penaeid prawns of the Portonovo coast of South India
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)There are very few reports on the diseases, parasites, commensals and fouling in penaeid prawns. During the regular collection of marine and estuarine prawns in the east coast of India, a number were found to be infested ... -
The biology of Penaeus monodon in the capture fisheries off orissa coast, India in the context of occurrence of natural broodstock
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The tiger prawn of India, Penaeus monodon Fabricius has a differential distribution in the two coasts of India. Density is high in the northeastern part of the Bay of Bengal gradually declining towards the mid-east and ... -
The tolerance of Penaeus monodon eggs and larvae to fungicides against Lagenidium sp. and Haliphthoros philippinensis
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The in vivo effect of mycostatic levels of fungicides against the fungi Lagenidium sp. and Haliphthoros sp. were tested on Penaeus monodon eggs and larvae. Hatching rate and survival of nauplii, zoeae, myses and postlarvae ... -
Environmental physiology of the prawn Penaeus (melicertus) latisulcatus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)There are a number of intrinsic and extrinsic factors which affect the normal routine activity of the prawn. The present study attempts to elucidate the optimum levels of various environmental factors for the culture of ... -
Thermal tolerance of larval greentail prawn Metapenaeus bennettae (Raced and Dall) a comparison with school prawn Metapenaeus macleayi
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The thermal tolerance of four larval stages of Metapenaeus bennettae was studied in the laboratory. Critical Thermal Maximum (CTM), One hour Median Lethal Temperature (lhLT50), and Median Resistance Time (MRT) were measured. ... -
Earthworm, marine annelids and squid as feed ingredients in formulated diets for juvenile Penaeus monodon
