    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.

    Project HALTapresyon

    The World Health Organization has deemed hypertension to be a global public health issue. In the Philippines, 25% of the adults who are 21 years and above have high blood pressure (2014). HALTapresyon is a project that aimed to prevent and manage hypertension in Barangay Igtalongon, Igbaras, by (1) increasing the knowledge, awareness, and practices (KAP) regarding hypertension by 15%, (2) increasing the KAP regarding physical activity by 15%, (3) increasing the KAP regarding nutrition by 20%, and (4) manage the blood pressure of hypertensive patients. The establishment of a core group and the passing of a resolution were done in order to ensure the sustainability of the project. HyperTEAMsion was also able to donate 6 blood pressure apparatuses for the continuation of the weekly blood pressure monitoring. The project implemented a series of lectures that focused on three aspects: basic knowledge, physical activity, and nutrition, which were identified as factors that greatly affect the development and progression of the disease. This was done to educate the community and promote a healthy diet and active lifestyle as a means of preventing the occurrence and aggravation of hypertension. Activities, such as DASH TAH!, Blood Pressure Moni-training, and the use of a journal, offered a more hands-on approach on educating and improving the practices of the residents. Information, education, and communication materials were also distributed to hypertensives and non-hypertensives alike. Post assessment mean scores for KAP on General Information, Physical Activity, and Nutrition, improved by 16.81%, 15.96%, and 29.70% respectively, all showing a statistical difference. For the non-hypertensives, there was a 36.94% increase in KAP. Weekly monitoring was done in relation to the management of blood pressure and it showed that 77.03% of the hypertensive individuals decreased or maintained their blood pressure. Therefore, Project HALTapresyon could be used on the prevention and management of hypertension.
