histopathology on the olfactory organ of a snakehead fish, channa punctatus (bloch, 1793) were assessed after exposing the fish to 2.5 mg/l and 5mg/l of cdcl 2 for 15 days, 30 days and 45 days. cellular organization of the epithelium was affected severely with degeneration of sensory and supporting cells and hyperplasia of basal cells and mucous cells. mucous cell proliferation indicates the up...

Collectively known as eucheumatoids, Eucheuma denticulatum, Kappaphycus alvarezii, K. malesianus, and striatus are the main farmed seaweed species in Philippines. The success of farming for over five decades country is due, part, to high diversity cultivars maintained by Filipino farmers. Notwithstanding fact that many eucheumatoid presently (and consistently) recognized farmers, there has been...

Blood pyruvate level in the fingerlings of Channa punctatus when subjected upto 48 hours to 5.6 mg/l (a sublethal concentration) of hexavalent chromium exposure, revealed statistically no significant increase. However, a progressive significant increase in the blood pyruvate level was noticed upto 96 hours of exposure. The result may prove useful parameters to assess the hexavalent chromium tox...

Study on bioconversion of ω-fatty acids extracted from giant snakehead (Channa micropeltes) fish oil was carried out using guinea pig lung homogenate. The fish oil, after hydrolysis to their fatty acids, was incubated aerobically at 37oC in phosphate buffer solution with the addition of guinea pig lung homogenate. After incubation and chemoreduction, it was found that ca. 76% arachidonic acid h...
