Item Antiviral genes in fish and their potential use in aquaculture: Emphasis on Japanese flounder, Paralichthys olivaceusCaipang, Christopher Marlowe (University of the Philippines Visayas, 2008)Viral diseases pose serious threat in aquaculture systems because they affect fish throughout their life stages. The identification and functional characterization of interferons, interferon-inducible genes and transcriptional factors in some species of fish showed the potential use of these antiviral genes for biotechnological applications to combat viral infections. This paper summarizes the studies conducted on an interferon-inducible gene, the Myxovirus resistance (Mx) protein and a transcriptional factor, the interferon regulatory factor-1 (IRF-1) in a flatfish, Paralichthys olivaceus. These genes possessed antiviral activity and mediate immune response during virus infections. Hence these genes and other putative antiviral genes in other species of fish, particularly warm-water aquaculture species should be characterized of their antiviral functions.Item The fishlore of Western VisayasDe Castro, Lourdes V. (University of the Philippines in the Visayas, 1992-08)Item Some aspects of the population biology of the reef coral, Pocillopora damicornis (Linnaeus), in Taklong Island, GuimarasNievales, Marie Frances (University of the Philippines Visayas, 1996)Demographic parameters that included growth rate, reproduction, recruitment and mortality ofthe branching reef coral, Pocillopora damicornis Linneaus, in Kalirohan reefflat, Taklong Island, Guimaras were investigated from 1991 to 1992. Radial colony growth averaged 20 mm per year regardless of initial size. Planulation was the predominant mode of reproduction. This occurred monthly throughout the year with peak larvae release between the new moon and first quarter. There was regular recruitment event of larval origin that corroborated monthly spawning. Size class specific mortality rates did not vary much but the largest size cohort had the least. Net larvae-derived recruitmentsurpassed depletion rate (natural mortality) of established colonies at the end of the study period. The observed demographic rates resulted in increased population size where more than half are recruits and maintained the left-skewed population size structure.Item Working wives in Philippine coastal fisheries(U.P. in the Visayas, 2000-12)
