The effects of dietary tryptophan levels on growth and metabolism of rainbow trout (Salmo gairdneri)
(Cambridge University Press, 1984)
1. Groups of rainbow trout (Salmo gairdneri) (mean weight 14 g) were given diets containing 0.8, 1.3, 2, 3, 4 or 6 g tryptophan/kg diet for 12 weeks.
2. By analysis of the growth results, the dietary requirement of ...
A histological study of the hypophysial-gonadal system during sexual maturation and spawning in the milkfish, Chanos chanos (Forskal)
(Wiley-Blackwell, 1985)
The pituitary gland of the milkfish, Chanos chanos, was studied at different stages of sexual maturation and spawning. Consecutive median sagittal sections were treated with a range of stains to demonstrate the different ...
The effects of temperature and starvation on the ultrastructure of the hepatocytes of seaperch fingerlings, Lates calcarifer (Bloch).
(Elsevier, 1987)
The hepatocytes of seaperch fingerlings reared on trashfish at constant water temperatures of 20 and 35°C were examined through electron microscopy and compared with those of controls fed identical diet or deprived of food ...
Studies on the causative organism of Sarotherodon niloticus (Linnaeus) fry mortalities - 2. Identification and characterization of the physiological properties of Pseudomonas fluorescens
(Japanese Society of Fish Pathology, 1985)
Identification and examination of the physiological characteristics of Pseudomonas sp. isolated from fry of Sarotherodon niloticus (L.) was conducted. Based on morphological and biochemical tests, the bacterium was identified ...
The economics of retarding milkfish growth for fingerling production in brackishwater ponds
(Elsevier, 1987)
Two experiments were conducted to measure the economic viability of retarding milkfish growth (stunting) in brackishwater ponds. In the first experiment, 2-month-old fish were reared for 6 months in ponds with initial ...
Water hardness determination using local laundry bar soaps for carp hatcheries
(Fisheries Research Society of the Philippines, 1988)
A simple method using local laundry soap is described for carp hatchery operation. A saturated soap solution was prepared and uses to titrate a 100-ml water sample of known hardness until a permanent lather appeared on the ...
Gum arabic, carrageenan of various types and sago palm starch as binders in prawn diets
(Fisheries Research Society of the Philippines, 1982)
Sago palm starch, gum arabic and three types of carrageenan (EPT-2, St-0008-29 & St-008-30A) were tried as binders in a practical diet. EPT-2 carrageenan gave consistently better water stability than the other binders in ...
Induced breeding and larval rearing experiments with milkfish Chanos chanos (Forskal) in the Philippines
(Elsevier, 1984)
Salmon pituitary homogenate was used alone or in combination with human chorionic gonadotropin, to induce spawing in captive and wild adult milkfish at ambient temperature (26–30°C) and salinity of 34%.. Healthy or slightly ...
Evaluation of milkfish (Chanos chanos Forskal) and prawn (Penaeus monodon Fabricus) in polyculture system
(Fisheries Research Society of the Philippines, 1982)
The growth, survival and profitability of milkfish (C. chanos ) and prawn (Penaeus monodon ) (averaging 3.1 g and 0.3 g, respectively) grown in five different combinations for 100 days in 500-m super(2) brackishwater ponds ...
