A new device for recording the feeding activity of milkfish
(The Japanese Society of Scientific Fisheries, 1981)
Knowledge on the feeding activity is basic and very important for rearing fish. The information on the feeding activity rhythm of the animal suggests the proper time to feed it. Many devices have been designed to record ...
Identification and characterization of vitellin in a hermaphrodite shrimp, Pandalus kessleri
(Elsevier, 1989)
1. A female specific protein (FSP, vitellogenin) in hemolymph and its related ovarian protein (vitellin) of Pandalus kessleri were studied by means of electrophoretical and immunological procedures.
2. The vitellin was ...
Algal production in wastewater: Progress and problems.
(E. Schweizerbartsche Verlagsbuchhandlung, 1987)
Algal production in wastewater is reviewed in two major areas: (1) production of single-cell proteins, and (2) its integration with aquaculture for the production of natural feeds. Progress achieved so far in the various ...
Reproductive performance and growth of Nile tilapia (Oreochromis niloticus) broodstock fed diets containing Leucaena leucocephala leaf meal
(Elsevier, 1988)
The effects of dietary leucaena leaf meal on reproductive performance and growth of Nile tilapia were determined. In the preliminary trial, sexually mature Nile tilapia were fed with a control diet or a test diet which had ...
Effects of various diets on the nutritional value of Artemia sp. as food for the prawn Penaeus monodon
(Springer Verlag, 1988)
The nutritional value of Artemia sp. as food for marine fish and crustacean larvae has been linked to the level of its polyunsaturated fatty acid (PUFA) content. Experiments in August 1984 were conducted to determine the ...
Induced spawning of maturing milkfish (Chanos chanos Forsskal) with gonadotropin-releasing hormone (GnRH) analogues administered in various ways
(Elsevier, 1987)
The response of mature female captive milkfish to mammalian and salmon gonadotropin-releasing hormone analogues (mGnRH-A and sGnRH-A) was investigated. Prior to spawning, six groups of three females received (1) 10–16 μg ...
Fate and location of Vibrio anguillarum in tissues of artificially infected ayu (Plecoglossus altivelis)
(Japanese Society of Fish Pathology, 1987)
Ayu (Plecoglossus altivelis) were infected with Vibrio anguillarum by a water-born method. At 6, 12, 18, 36, 38-45 (moribund stage) and 48 h (dead) after infection, fish were sampled to determine the fate and location of ...
Dose-dependent spawning response of mature female sea bass, Lates calcarifer (Bloch), to pelleted luteinizing hormone-releasing hormone analogue (LHRHa)
(Elsevier, 1989)
The induction of sequential spawnings of mature female sea bass following intraperitoneal implantation of various doses of luteinizing hormone-releasing hormone analogue (LHRHa) in a 95% cholesterol pellet was investigated. ...
Ingestion saturation and growth responses of Penaeus monodon larvae to food density
(Elsevier, 1989)
Different larval stages of Penaeus monodon were fed with increasing densities of Tetraselmis sp. to evaluate the relationship between food density, ingestion rates, development and growth of Penaeus monodon larvae. Ingestion ...
Amino acid requirements for growth of Nile tilapia
(American Society for Nutrition, 1988)
A series of feeding experiments was conducted in aquaria to determine the quantitative requirements of the 10 essential amino acids for growth of young Nile tilapia (Oreochromis niloticus). The test diets contained casein ...
