    Survival and growth of the sea cucumber Holothuria scabra (Jaeger) juveniles reared at different diets
    Baylon, Basil C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2009-03)
    Sea cucumbers are economically important species, with high demand in local and international markets. Overharvesting due to this high demand causes depletion of wild populations of sea cucumbers. Stock enhancement has been resorted to improve the status of natural populations. This will need the development of rearing technology which includes studies on the effects of different diets on sea cucumber juveniles. In this study, the effects of five diets on growth and survival of sea cucumber Holothuria scabra juveniles were compared. The five treatments used were benthic diatoms (Navicula sp.) alone, combination of benthic diatoms and seaweed (Sargassum sp.) extract, seagrass extract alone, combination of benthic diatoms and seagrass (Thalassia sp.) extract, and commercial shrimp feed. Three replicates were used for each treatment. For every replicate. 10 juveniles with body length 1-2 mm were reared in a 3-L culture container with seawater and no sand substrate. Salinity ranged from 32-35 ppt and the temperature from 26-29°C. It was observed that there was a trend of increasing body weight, body length, and body width of juveniles as weeks of culture progressed. After 7 weeks of culture, best weight gain, increase in body length and body width was achieved in juveniles fed with either benthic diatoms alone or combination diet of benthic diatoms and seaweed extract. There was high survival in all feeding treatments except in H. scabra juveniles fed with commercial shrimp feed. The lowest body weight, length and width and lowest survival were consistently obtained from juveniles given commercial shrimp feed.

    Indigenous knowledge, beliefs, and practices in rice farming of people in Cuyo Island, Palawan
    Acero, Agnes B.; Prado, Edelyn A. (Division of Social Scviences, College of Arts and Sciences, University of the Philippines Visayas, 2005-03)
    This study was conducted to determine the indigenous knowledge, beliefs, and practices in rice farming of people in Cuyo Island, Palawan. It also aims to find out the indigenous knowledge, beliefs and practices in planting, harvesting, storing, processing, and selling rice products. Both primary and secondary data are used in this study. Data collection was done using interview schedule. Two sets of respondents were interviewed to collect data - the farmers and some key informants such as the barangay captains, and the oldest people of the two (2) barangays. The study was conducted in the barangays of the Municipality of Magsaysay, Cuyo Island, Palawan. These barangays are Igabas, Emilod, and Balaguen. Data were analyzed using descriptive statistics. Results of the study show that Cuyunon farmers have many existing traditional practices related to planting, harvesting, storing, processing, and selling rice products. It also shows that Cuyunons practice traditional farming in the same way that upland rice farmers in some parts of the Philippines do. Based on the results the researchers recommend that the following aspects about the Cuyunon farmers should also be studied: (1) existing development programs implemented by the Government Agencies, and NGOs related to rice farming in the locality; (2) assessments of farmers attitude towards these programs; (3) accessibility of the technology introduced by these agencies; and (4) feasibility of establishment of a people’s organization among the farmers.
