showed that as to the efficiency of each culture medium based on the water level it was found out that on the surface level the C. lentillifera placed in plastic screen cage has the highest growth rate in Site 1 (muddy site) and tubular nets ranked first in site 2 (rocky) and site 3 (sandy).For the middle layer based on the mean weight of the plant showed that tubular nets has the highest in site 1 (muddy) and plastic screen cage got the highest in site 2 (rocky) and 3 (sandy). For the bottom layer the tubular plastic screen dominates the highest growth rate of all the culture media used from site 1, 2 and 3. Middle layer is the best layer for the off bottom culture of lato using the plastic screen cage based on the highest mean growth of the plant. Analysis of Variance (ANOVA) revealed that there is no significant difference on the growth rate of Caulerpa lentillifera placed in plastic screen cage, tubular nets with the different water levels in the three culture sites.
Camotes Islands is noted of its Camotes Sea as one of the fishing grounds in the Philippines. Extraction of the marine resources including holothurians in this fishing ground has been felt by the fishermen; hence, this study was conducted in order to find out its gleaning methods used, species gleaned, extraction rate and perception on the distribution of holothurians in the four municipalities of Camotes Islands which are San Francisco, Poro, Tudela and Pilar. Interview guide and actual field visits in the areas were used to gather the data. Results show that gleaning methods of gathering holothurians in Camotes Islands were handpicking, using bolo, water goggles, pointed wood, iron bars and by spears both in day and night operations. Frequently gleaned sea cucumber spe cies are Stichopus hermanni, Bohadschia paradoxa, Bohadschia marmorata, Stichopus horrens, Holothuria nobilis, Stichopus variegatus and Holothuria pulla which are also the species that were caught throughout the year.The size of the Holothurians gathered measures from 5-10 cm and the perceived distribution distance of gleaned holothuria in the site is 1-5 m. The amount of catch is 1/2 kilo per 1-2 hours gleaning time followed by "no catch" and the third is 0.51 to 1.0 kg and the gleaning frequency of holothurians in the entire Camotes Islands is 2-4 times a week.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
