Harvesting techniques for Nile tilapia fingerlings
(Fisheries Research Society of the Philippines, 1986)The experiment was conducted in nine-320m2 - freshwater ponds to evaluate various techniques of harvesting tilapia fry. Three treatments with three replicates each were used: harvesting by seining the fry ... -
Hatchery production of Oreochromis niloticus L. at different sex ratios and stocking densities
(Elsevier, 1988)The influence of various sex ratios and stocking densities on hatchery production of Nile tilapia, Oreochromis niloticus L., was studied in land-based (concrete tanks) and lake-based (hapa nets) systems. In both hatchery ... -
Hatchery rearing of sea bass Lates calcarifer Bloch
(Science and Technology Information Institute, 1991)A hatchery rearing scheme for sea bass (Lates calcarifer Bloch) is described. Survival rate from hatching (d0) to harvest (d30) was 34%. Feeding sea bass fry with Chlorella-fed or Selco-enriched instar II Artemia from d19 ... -
Hatchery-produced milkfish (Chanos chanos) fry should be fed docosahexaenoic acid-enriched live food: A case of the difficulty in the transfer of improved aquaculture technology in the Philippines
(Ministry of Tropical Agricultural Research Centre, 2006)Levels of highly-unsaturated fatty acids, the most important nutritional factors in fry production of marine fish, were compared between hatchery-produced and wild-caught milkfish Chanos chanos fry. The most striking ... -

(San Carlos Publications, University of San Carlos, 1989)Hormone-induction of spawning in bighead carp Aristichthys nobilis Rich. by single or double intraperitoneal injection with varying combined dosages of HCG and LHRH-A was conducted. Fish were spawned successfully following ... -
High amorphous poly-beta-hydroxybutyrate (PHB) content in a probiotic Bacillus strain displays better protective effects in Vibrio-challenged gnotobiotic Artemia
(Elsevier, 2018)In this study, the Bacillus sp. JL47, a superior PHB-accumulating Bacillus strain identified from the previous work, was tested for its protective effects in gnotobiotic Artemia franciscana during a pathogenic Vibrio ... -
Histidine requirement of snubnose silver pompano Trachinotus blochii
(Elsevier, 2023-05-25)Histidine is necessary for the formation and repair of tissues to mitigate the effects of cataract on some fish species. Although the requirements for dietary amino acids of several Trachinotus species have been reported, ... -
Histological observations on the rearing of milkfish, Chanos chanos, fry using different diets
(Blackwell Publishing, 1986)Six different diets, commonly used in the Philippines for rearing milkfish, Chanos chanos, try, were tested by means of growth, survival and histology. These diets included: a) live food (Artemia nauplii); b) two different ... -
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 ... -
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 KMnO4. Histopathological analyses of gills, liver, and kidney tissues revealed significant changes ... -
Histopathology of microsporidian infection in white prawn, Penaeus merguiensis de Man, 1888.
(University of the Philippines, 1982)Different stages of the white prawn, Penaeus merguiensis de Man, were examined for microsporidian infection. The parasite was found only in adult female prawns exhibiting white instead of the normal olive-green ovaries. ... -
