Amino acid and fatty acid profiles in aquaculture nutrition studies
(Asian Fisheries Society, 1989)
The amino acid profile is an important parameter in the evaluation of protein quality and in requirement studies. Amino acid profiles are usually determined in 2 steps: hydrolysis of the protein to constituent amino acids ...
Growth and survival of Nile tilapia fingerlings in net cages without supplemental feed in Laguna Lake, Philippines
(Asian Fisheries Society, 1986)
Oreochromis niloticus fingerlings were stocked at densities of 50, 100, 150 and 200 fish/m super(2) in fixed net cages in Laguna Lake, Philippines. These were reared without supplemental feed on 1 April-30 July 1980, 5 ...
Preliminary trials of combined Artemia rearing and salt production in earthen salt ponds in the Philippines
(Universa Press, 1980)
This paper describes trials at combining Artemia rearing with salt production during the dry season, in newly-constructed earthen salt ponds (reservoir, evaporation, concentration, and crystallization ponds, total area of ...
Induced spawning and larval rearing of grouper (Epinephelus salmoides Maxwell)
(1986)
Broodfish of grouper (Epinephelus salmoides ) were induced to spawn by hormonal induction. The hormones used for this experiment were HCG + pituitary gland (PG) and LRH-a. The results showed that at dosages of 500 IU HCG ...
The effect of various levels of protein, fat carbohydrates and energy on growth, survival and body composition of Chanos chanos fingerlings
(Center for Agricultural Publishing and Documentation, Pudoc Wageningen, 1989)
Rice and fish are staple foods in the Philipines as well as in other parts of Southeast Asia, where calorie/protin malnutrition is a serious probem. Milkfish, (Chanos chanos) is well-liked by the masses and, therefore, ti ...
Polyculture of the tiger shrimp (Penaeus monodon) with Nile tilapia (Oreochromis niloticus) in brackishwater fishponds
(1988)
A study was conducted in fifteen 500-m<sup>2</sup> ponds to determine the growth, survival and production of Penaeus monodon (Fabricius) in polyculture with Oreochromis niloticus (Linnaeus) and the extent of competition ...
Interaction of the midgut gland and the ovary in vitellogenesis and consequences for the breeding success: a comparison of unablated and ablated spawners of Penaeus monodon
(European Aquaculture Society, 1989)
The midgut glands and ovaries of unablated and ablated females of Penaeus monodon were examined before and after spawning by light and electron microscopy to elucidate the role of the midgut gland during vitellogenesis. ...
Effect of feeding regimes on growth and survival of bighead carp (Aristichthys nobilis Richardson) fry
(Asian Fisheries Society, 1989)
Two five-week feeding trials were undertaken to evaluate growth and survival of bighead carp (Aristichthys nobilis ) fry of 1.9-2.4 mg mean weight reared on various feeding regimes. In Treatment 1, the carp fry were fed ...
Growth, molting, food ingestion, and absorption in juvenile Macrobrachium rosebergii in relation to dissolved oxygen
(European Aquaculture Society, 1989)
Growth, molting, food ingestion, and absorption in juvenile Macrobrachium rosenbergii were evaluated at 2.5, 3.5, 5.0, and 7.7ppm dissolved oxygen (DO), 29°C, and 0.5°/oo salinity. DO levels were maintained by bubbling ...
Hematological and histopathological changes in Oreochromis mossambicus after exposure to the molluscicides Aquatic and Brestan
(Department of Fisheries; International Center for Living Aquatic Resources Management, 1988)
Duplicate static 96-hour bioassays were conducted to determine the median lethal concentration for Oreochromis mossambicus (LC<sub>50</sub>) of two organostannous molluscicides, commonly used in fishponds: Aquatin and ...
