Abstract

Generally, this study was intended to examine the problems or implementation of turtle conservation in Talise, Gangga and Bangka Islands and specifically with a number of objectives to: know the introduction of sea turtle, to know sea turtle fishing and turtle exploitation, to know the knowledge of the people about turtle as a protected animal. Survey results on Talise Island, Gangga and Bangka showed that people who had seen turtles directly: Talise Island 94%, Gangga 58%, and Bangka 92%. Local residents of Talise, Gangga and Bangka Islands know well the turtles even see directly in their habitat and spawning time. In Talise, Gangga and Bangka Islands,  turtles are still commonly caught, traded and consumed by local people.  People's awareness about turtles as protected animals is lacking.  Keywords: Turtle, Talise Island, Gangga and Bangka

Abstract

Abstract Nearly 30 years since an assessment on the local harvest of Caulerpa racemosa at Solong-on, Siquijor, we conducted a similar study in November 2013. Present CPUE of Caulerpa is significantly lower than it was in the 1980s. Probable factors attributing to this decline are briefly enumerated and discussed. Keywords: seaweed, lato, harvest, Siquijor, Philippines

Abstract

The importance of seagrasses in terms of ecological and economic benefits are well-known. This paper describes the status of research on seagrasses conducted so far, with relevance to the North Sulawesi region. Most of the studies done in Indonesia, especially in North Sulawesi, have focused on species richness and biodiversity as well as basic biological questions such as biomass and morphometric differences of certain seagrass species between sampling localities. While several studies have been conducted, there is a general need for Indonesian marine scientists to expand research areas related to food-web dynamics and inter-connectivity of major fishery and nursery habitats (mangroves-seagrass-coral reefs) with the aid of modern tools (e.g. molecular approach).   Keywords: benefits, biology, ecology, economic, seagrass

Abstract

This study aimed to evaluate the benefits of Terminalia catappa L. leaf extract on the growth of Kappaphycus alvarezii seaweed. Treatment A (control /without soaking into ketapang leaf extract), treatment B (soaking into ketapang leaf extract at the beginning of maintenance), C (soaking ketapang leaf extract every 1 week) and D (soaking into ketapang leaf extract every 2 weeks). Differences in growth of K. alvarezii seaweed for 42 days were not significantly affected by differences in the frequency of immersion of ketapang leaf extract. Absolute growth of Fcount (3.9521977 tn) <Ftable value of 5% (4.06), relative growth of Fcount (2.957545 tn) <Ftable value of 5% (4.06) and daily growth rate of Fcount (3.237068tn) <Ftable value of 5% (4.06). Even so the results of absolute growth measurements, relative growth and the best daily growth rate on soaking ketapang leaf extract every two weeks, followed by soaking ketapang leaf extract at the beginning of cultivation, soaking ketapang leaf extract every one week and without soaking into leaf extract.

Abstract

We briefly describe the localized abalone (Haliotis asinina) fishery in Siquijor Island, central Philippines and discussed the possible reasons of the sudden collapse in local trade and fishery. The lack of management system may have contributed to over-exploitation of abalone leading to closure in 2012. Prior to the collapse in 2012, abalone gatherers spent an average of 4.18±0.15 hours/day/site with catch-per-unit-effort (CPUE) of H. asinina ranged from 0.1 to 0.6 kg/person/hr with mean value of 0.25±0.03 (SE) kg/person/hr. Recommendations to revive and sustain the abalone fishery of Siquijor Island are also provided.   Keywords: abalone, fishery, overharvesting, Siquijor
