The use of haptophyceae in rearing experiments on larval Penaeus orientalis
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The food value of five clones of Haptophyceae, Coccolithus pelagicus, Dicrateria zhanjiangensis, Isochrysis galbana, Tahitian Isochrysis aff. galbana, and Pseudoisochrysis paradoxa were tested for larval Penaeus orientalis. ...
Earthworm, marine annelids and squid as feed ingredients in formulated diets for juvenile Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Earthworm and annelids were incorporated in diets for Penaeus monodon juveniles (mean weight 0.54 g) either in wet or dry form. These protein sources were added in amounts needed to replace 10% of the animal source of ...
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 ...
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 ...
Molt staging in adult Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Changes and formation of cuticular layers and setae bordering the uropods and endopodites of the pleopods of adult Penaeus monodon were examined under a light microscope. Observations and photographs were made at 0, 12 and ...
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 ...
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 ...
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 ...
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 ...
Characterization of ovarian maturation stages in wild unablated Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
At least five wild-caught Penaeus monodon from various maturation stages (initially classified in vivo as 0, I, II, III, IV, V) were measured, weighed and dissected for histological and histochemical studies. The anterior ...
