Staggered harvesting as a method of increasing prawn production with supplemental feeding
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Prawns, like any other animals, exhibit dissimilarities in growth rates. As they grow, a wide range of body weight distribution from the same population is observed. Staggered harvesting method is commonly practised in ...
Lipids and essential fatty acids in the nutrition of Penaeus monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Total lipid levels and fatty acid distribution during larval development of Penaeus monodon were determined. Larvae were cultured utilizing standard rearing procedures and feeding schemes adopted by the Crustacean Hatchery ...
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 ...
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 ...
Morphometric studies on three Penaeid shrimps, Penaeus japonicus, P. vannamei and P. marginatus in Hawaii
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Penaeus japonicus, P. vannamei and P. marginatus cultured at the Oceanic Institute in Hawaii, were sampled and measured. The shrimps sampled ranged from 1 to 15 g in body weight. The measurements included carapace length ...
Variation in tissue lipid content and fatty acid composition during ovarian maturation of unablated and ablated Penaeus monodon broodstock
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The tissue lipid content and fatty acid composition in the hepatopancreas, tail muscle and gonad of unablated and ablated Penaeus monodon were determined. Females at various stages of maturity were collected from offshore ...
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 ...
The influence of temperature and salinity on oxygen consumption of Penaeus monodon postlarvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The effect of salinity and temperature on oxygen consumption at different developmental ages of Penaeus monodon postlarvae (P5 to P60) was studied. The design was a 2 × 5 factorial, using two levels of temperature (15 and ...
Carbohydrate requirements of Penaeus monodon juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Penaeus monodon juveniles (initial mean weight=0.62 g) were fed semi-purified diets containing 10, 20 and 30% trehalose, sucrose or glucose for eight weeks. Results showed that shrimps fed 20% trehalose gave the highest ...
