Results revealed that only four of the eleven species, C. racemosa, C. lentillifera, C. chemnitzia var. peltata, and C. cylindracea, have massive populations;The four Caulerpa sites are the municipalities of Arteche, Guiuan, Salcedo (Matarinao Bay) and Quinapondan, and species C. racemosa, C. lentillifera, and C. chemnitzia var. peltata are most preferred edible species which are considered in the local diet. The study concludes that the distribution of Caulerpa in Eastern Samar is area-specific and should therefore be considered in resource planning and management, particularly in relation to aquaculture.展开更多

Highlights of the profile are river width, depth, water velocity and water flow rate, potential source, river stretch, flood height and flood plain as inputs to development and disaster planning. Data presented here were based on field surveys supported and guided by reference maps. Based on the survey, a potential source of Oras and Ulot-Can-avid Rivers is San Jose de Buan, Samar while Suribao River flows from the closed-canopy forest from Borongan-Maydolong-Llorente (Eastern Samar). Flooding and erosion were observed in the three rivers, but the highest silt deposits and the widest flood plain were in Oras River, with the highest water flow rate in the upstream. Erosion and quarrying were observed in all rivers. Bamboo reforestation is conducted in Suribao River as river bank erosion control measures. Results of the survey revealed the high risk to our rivers and river villagers due to flooding and erosion, in addition to the loss of properties and livelihood, and the ecological conservation of the landscape. Collective rehabilitation measures should be crafted for a unified action to address environmental issues parallel to development plans to promote but sustainably manage our resources and protect our villagers.展开更多

Identification of species with natural populations, species with massive natural populations and the edible species favoured by the local residents were the specific objectives of this study. The observed massive population with 85% cover in 100 sqm was a combination of the nine Caulerpa species, which are C. racemosa, C. lentillifera, C. chemnitzia var. peltata, C. cylindracea, C. brachypus, C. macrophysa, C. microphysa, C. serrulata and C. sertularioides. The majority, 98%, was composed of C. racemosa and C. lentillifera, while other species were observed in one to two feet of stolon length underneath the two species. C. racemosa and C. lentillifera were identified as the most locally consumed species by 100% of the respondents, but C. lentillifera was most preferred by 98% due to its thinner ramuli over C. racemosa. Results revealed that Sulangan is a potential area for Caulerpa aquaculture with reference to the specific location and specifically to C. racemosa and C. lentillifera. Preliminary trials on Caulerpa aquaculture can be initially introduced;however, seasonality should be validated.展开更多
