    Identification of intertidal fungi from mangroves in Iloilo River
    Bonifacio, Jo F. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2002-04)
    This study aims to describe, identify and classify intertidal fungi through direct examination of the collected mangrove wood samples in Iloilo River, Iloilo City, Philippines. This will provide additional information about the occurrence of fungi in estuarine environments. One hundred samples of decayed but attached roots and stems of unidentified mangroves were collected in each of the intertidal zone of the three study sites (Study Site I: Sooc, Oton, Iloilo; Study Site II: Dulonan, Arevalo, Iloilo City; Study Site III: Diversion River, near Marina Restaurant) in Iloilo River. In Study Site 1, The total number of species collected was 11, 4 of which belong to Phylum Ascomycota, 2 belong to Phylum Deuteromycota and 5 belong to Phylum Basidiomycota. In Study Site II, there were 10, 6 belong to Phylum Ascomycota, 3 to Phylum Deuteromycota and 1 to Phylum Basidiomycota and in Study Site III, total number of species was 14, 7 belong to Phylum Ascomycota, 4 to Phylum Deuteromycota and 3 to Phylum Basidiomycota. The total number of species of fungi collected in the three study sites were 20 (8 ascomycetes, 7 basidiomycetes, and 5 deuteromycetes). The frequently occurring fungi (10-29 % fiequency of occurrence) are Eutypa sp. (15.3%), followed by Periconia prolifica (13 %) and Verruculina enalia (10.3%). The remaining 17 species were collected infrequently (<10 % fiequency of occurrence). The ascomycetes were the most dominant group of fungi collected in this study.

    The effect of seaweed (Kappaphycus alvarezii) as a partial substitute for commercial feed on the growth of chicken
    Bedia, Alma Mae S. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1994-08)
    The study determined whether the use of seaweed (Kappaphycus aIvarezii) in different amounts as a partial substitute to commercial feeds would enhance the growth of chickens, reduce feed consumption, increase feed efficiency, and increase profit. The chickens were first fed with commercial broiler starter mash feeds for 15 days. Then, on the 16th day to the 35th day, the chickens were fed with different combinations in 1:1, 1:2, and 1:3 ratios of commercial broiler finisher feeds to K. alvarezii. Chickens fed with purely commercial broiler finisher feeds served as the control. Feed consumption, liveweight gain, and feed efficiency were computed every three days, while Profitability was determined at the end of the experimental period. Results showed that the use of K. alvarezii as a partial substitute to commercial broiler finisher feeds in a 1: 1 ratio increased the profit as well as the growth of the chickens, and it is comparable to that in the control (fed with purely commercial broiler finisher feeds). When the amount of K. alvarezii in the feed ration is more than 50% (1:1 ratio), it was observed that it would hamper the growth of the broilers.
