The milkfish seed resources survey in Sri Lanka: Status, problems and recommendations
(Ministry of Fisheries and Aquatic Resources, Sri Lanka, 1986)
A summary is provided of information concerning the milkfish (Chanos chanos) seed resources of Sri Lanka, highlighting problems related to seed collection. Various recommendations are made to overcome these problems and ...
Spawning behavior and early life history of the rabbitfish, Siganus guttatus, in the laboratory
(Elsevier, 1986)
The spawning behavior and embryonic and larval development of Siganus guttatus are described from laboratory observations. Characteristic prespawning behavior began 4 h before actual spawning: the female touched the anal ...
Effect of stocking density and duration on stunting milkfish fingerlings in ponds
(Taylor & Francis, 1986)
The paper discusses the effect of stocking density and holding periods in stunting milkfish fingerlings in brackishwater ponds using twelve units of 144m<sup>2</sup> earthen ponds. With 15, 20, and 25 fingerlings/m<sup>2</sup> ...
Shift in steroidogenesis in the ovarian follicles of the goldfish (Carassius auratus) during gonadotropin-induced oocyte maturation
(Japanese Society of Developmental Biologists, 1986)
Both partially purified chum salmon gonadotropin and 17α-hydroxyprogesterone stimulated in vitro production of testosterone by postvitellogenic follicles of goldfish (Carassius auratus). Chum salmon gonadotropin further ...
Specific amino acid-free semi-purified diets for Penaeus monodon juveniles
(Kagoshima University Research Center for the South Pacific, 1986)
To determine the effects of deficiency of individual amino acids believed to be essential to Penaeus monodon juveniles, a 28-day feeding experiment was carried out with P. monodon postlarvae.
P. monodon postlarvae ...
Histopathological response of milkfish Chanos chanos Forsskal fingerlings to potassium permanganate
(Japanese Society of Fish Pathology, 1986)
Static 96 h bioassays were conducted on milkfish fingerlings at concentrations ranging from 1.00 to 1.80 mg/l KMnO<sub>4</sub>. Histopathological analyses of gills, liver, and kidney tissues revealed significant changes ...
Immuno-response in tilapia Sarotherodon niloticus vaccinated with Edwardsiella tarda by hyperosmotic infiltration method
(Elsevier, 1986)
Sarotherodon niloticus with average weight of 28.42 ± 1.87g were immunized with formalin-killed Edwardsiella tarda using the hyperosmotic infiltration method. Test fish maintained in 30 l aquaria were grouped into four ...
The ultrastructure of the hepatocytes of the giant seaperch, Lates calcarifer (Bloch) (Pisces: Centropomidae), during starvation and refeeding with different diets.
(The Marine Biological Association of Hongkong, 1986)
Three groups of immature seaperch acclimated in the laboratory on a mixed commercial pellet and minced trashfish diet were starved for 30 days. Thereafter, the first group was starved for 7 more days, the second was refed ...
Evaluation of practical diets in the culture of the rabbitfish, Siganus guttatus (Bloch) (Pisces: Siganidae) using liver ultrastructural methods
(Elsevier, 1986)
The starvation-induced ultrastructural modifications in the hepatocytes were reversed when Siganus guttatus resumed feeding on a suitable feed. The liver cells regained their structural integrity soonest when the fish was ...
Feed preference of milkfish (Chanos chanos Forsskal) fry given different algal species as natural feed
(Elsevier, 1986)
Acclimated milkfish fry (mean wet weight, 6.0 mg) were fed with unialgal cultures of five species of freshwater algae: Oscillatoria quadripunctulata, Chroococcus dispersus, Navicula notha, Euglena elongata and Chlorella ...
