Quantitative and qualitative analyses of the bacterial microbiota of tilapia (Oreochromis niloticus) cultured in earthen ponds in the Philippines
(Springer Verlag, 2015)
The quantity and composition of the bacterial microbiota in the rearing water, sediment, gills and intestines of tilapia Oreochromis niloticus collected every 2 weeks from Day 30 to Day 120 after stocking for grow-out ...
Surveillance of emerging fish viral pathogens in some Southeast Asian countries
(Society of Israeli Aquaculture and Marine Biotechnology, 2009)
Preventing the transboundary movement of fish viral pathogens in a global environment requires active surveillance. This study examined the presence of three emerging viral pathogens among koi, common, grass, and silver ...
Gill lesions associated with acute exposure to ammonia.
(University of the Philippines, 1982)
The histopathological effects of the 96 hr LC<sub>50</sub> at 20.65 ppm NH<sub>3</sub>-N on the gills of milkfish fingerlings were examined qualitatively. Lesions observed were hypertrophy, hyperplasia, fusion of the ...
Seabream GnRH: partial cDNA cloning, localization and stage-dependent expression in the ovary of snake head murrel, Channa striatus
(Springer Verlag, 2005)
Vertebrate reproduction is under the neuroendocrine control of the hypothalamic decapeptide GnRH which synchronizes various reproductive events and influences other reproduction related aspects like spawning behavior and ...
Gill structure, anatomy and habitat of Anodontia edentula: Evidence of endosymbiosis
(National Shellfisheries Association, 2001)
Surveys and interviews were conducted to determine sources and habitat of Anodontia edentula. Results showed that they inhabit muddy substrate of mangrove areas or the adjacent mudflats, burying at 20-60 cm deep in the ...
Prevalence of white spot syndrome virus (WSSV) in wild shrimp Penaeus monodon in the Philippines
(Inter Research, 2007)
Prevalence of white spot syndrome virus (WSSV) was determined using polymerase chain reaction (PCR) methodology on DNA extracted from the gills of wild black tiger shrimp Penaeus monodon collected from 7 sampling sites in ...
Air breathing of aquatic burrow-dwelling eel goby, Odontamblyopus lacepedii (Gobiidae: Amblyopinae)
(Company of Biologists, 2006)
Odontamblyopus lacepedii is an eel goby that inhabits both coastal waters and intertidal zones in East Asia, including Japan. The fish excavates burrows in mudflats but, unlike the sympatric amphibious mudskippers, it does ...
Salinity tolerance of larvae of the mangrove red snapper (Lutjanus argentimaculatus) during ontogeny
(Elsevier, 2000)
Salinity tolerance and the effects of salinity on growth, condition factor and chloride cell (CC) densities were evaluated for Lutjanus argentimaculatus larvae during ontogeny. Tolerance of L. argentimaculatus larvae to ...
Changes in Na+, K+-ATPase activity and gill chloride cell morphology in the grouper Epinephelus coioides larvae and juveniles in response to salinity and temperature
(Springer Verlag, 2000)
The activity of the enzyme Na<sup>+</sup>, K<sup>+</sup>-ATPase and morphological changes of gill chloride cells in grouper, Epinephelus coioides larvae and juveniles were determined 6–48 h after abrupt transfer from ambient ...
Effects of Gusathion A on the survival and shell quality of juvenile Penaeus monodon
(Elsevier, 1991)
Juvenile Penaeus monodon (body weight=10–20 g) were exposed to a commonly used organophosphate pesticide, Gusathion A, in ponds for 96 h. Prawns exposed to 1.5–150 ppb Gusathion A had 27–53% shell softening, with a 96 h ...
