Histopathology of the chronic soft-shell syndrome in the tiger prawn Penaeus monodon
(Inter Research, 1987)
One of the disease problems that affect the production of tiger prawn Penaeus monodon Fabricius in brackish-water ponds is the chronic soft-shell syndrome, a condition in which the prawn shell is persistently soft for ...
Transition from endogenous to exogenous nutrition sources in larval rabbitfish Siganus guttatus
(Japanese Society of Fisheries Science, 1988)
The early larval development of Siganus guttatus was studied with emphasis on the transition from endogenous to exogenous feeding. Three rearing trials were conducted as follows: 1) rearing in a 5 ton concrete tank at ...
Effect of different stocking combinations on growth, production and survival of milkfish (Chanos chanos Forskal) and prawn (Penaeus monodon Fabricius) in polyculture in brackishwater ponds
(Elsevier, 1981)
Milkfish (Chanos chanos) and prawn (Penaeus monodon) were stocked in 500 m2 earthen ponds from 12 November 1978 to 15 March 1979 at the following combinations: 2000 milkfish fingerlings per ha (treatment I); 2000 milkfish ...
Survival and some histological changes in Penaeus monodon Fabricius juveniles fed various carbohydrates
(Elsevier, 1983)
Juveniles of P. monodon Fabricius (initial mean weight 1.76 g) were reared on semipurified diets containing 10 or 40% maltose, sucrose, dextrin, molasses, cassava starch, corn starch or sago palm starch for 6 weeks. Highest ...
A comparison of two prawn (Penaeus monodon ) brood stock systems—land–based tanks and marine pens
(World Aquaculture Society, 1981)
The paper compares two prawn (Penaeus monodon) brood stock systems—land-based tanks and marine offshore pens. Construction costs and annual maintenance and operating costs total US\$1,430 and \$2,550 for the tank and \$1,500 ...
The mechanics of mass occurrence and recruitment strategy of milkfish Chanos chanos (Forsskal) fry in the Philippines
(Kagoshima University Research Center for the South Pacific, 1983)
The daily and hourly catch of milkfish Chanos chanos (Forsskal) fry in the coast of Hamtic, Panay Island in the Philippines was recorded over a period of 16 weeks, and correlated with time, location, types of gear, and ...
Ascorbic acid sulfate sulfohydrolase (C2 sulfatase): the modulator of cellular levels of L-ascorbic acid in rainbow trout.
(National Academy of Sciences of the United States of America, 1982)
The enzyme L-ascorbic acid 2-sulfate sulfohydrolase (C2 sulfatase) was purified from rainbow trout liver. The enzyme catalyzes the hydrolysis of L-ascorbic acid 2-sulfate and has a pH optimum at 6.0. It has a molecular ...
Vertical diurnal migration of Daphnia cucculata and Eudiaptomus graciloides in eutrophic Frederiksborg Castle Lake, Denmark
(University of the Philippines at Los Baños, 1982)
In euthrophic Frederiksborg Castle Lake, Berg & Nygaard were the first to study vertical migration. They obtained water samples at various time intervals over several days and concluded that the bulk of the population of ...
The effect of dietary protein-energy levels on growth and metabolism of milkfish (Chanos chanos Forsskal)
(Elsevier, 1988)
<ol><li>Groups of milkfish juveniles (mean weight, 2.8 g) were fed diets containing white fishmeal and gelatin with varying protein-energy to total metabolizable energy (PE:TME) ratios.</li><li>Amino acids were incorporated ...
Critical factors influencing survival and hatching of milkfish (Chanos chanos Forsskal) eggs during simulated transport
(Elsevier, 1988)
The effects of loading density, length of transit time, temperature and salinity on milkfish (Chanos chanos Forsskal) eggs during simulated transport were examined. Rocking motion approximating conditions of transport of ...
