The sustainable management of small-scale fisheries in coral reef ecosystems constitutes a difficult objective not least because these fisheries usually face several worsening pressures, including demographic growth and climate change. The implications are crucial in terms of food security as fish represents the major protein source for local populations in many regions reliant on small-scale fisheries. The case of the Solomon Islands’ fishery presented in this paper represents an illustrative example of these issues.
Periodically-harvested fisheries closures are emerging as a socially acceptable and locally implementable way to balance concerns about conserving ecosystem function and sustaining livelihoods. Across the Indo-Pacific periodically-harvested closures are commonly employed, yet their contribution towards more sustainable fisheries remains largely untested in the social and ecological context of tropical small-scale fisheries.
Details are given of a project undertaken in the central Philippines concerning various factors affecting coral reefsand the protective management of the coral reefs.
The main purpose of the study is to determine whether non-use values exist among residents of Quezon City, hundreds of kilometers away from Tubbataha Reefs. The dichotomous choice contingent valuation method (CVM) was employed across 800 randomly selected respondents, 400 of which were personally interviewed (PI) and 400 were asked to accomplish self-administered (SA) questionnaires, 198 of the latter were found useable for the study.
In analyzing the structure of small scale fisheries in West Sumatra waters the need was found for diversification of current fishing gear. Trials were conducted using a coral reef longline as an alternative gear; using different kinds of baits and operating in different depths, the coral reef longline can be adjusted to select mainly mature fish, but proper identification of species is of importance in determining size at maturity.
The potential productivity of coral reefs is discussed, considering problems involved in the different types of the reefsituations. The overall result is that coral reef fish on a world-wide basis are under-exploited.
The importance of coral reef systems to coastal fishery resources in the Philippines has become a focal point in certain government planning and research activities. Estimates of the contribution of reefs to the total fisheries production are based on 3 factors: reef area, maximum sustainable yield and total fisheries production. A method forthe gauging of coral reef production is presented.
This guide was developed to document the process and activities that WorldFish staff have used and adapted as facilitators working with communities interested in marine resource management in Solomon Islands. It draws on the experiences from work conducted with FSPI and MFMR through ACIAR funded projects, with communities that had a primary interest in the management of coral reef fisheries. Since 2011 the process has been trialed and adapted further with communities interested in mangrove ecosystem management (through the MESCAL project).
A literature review indicated that artificial reefs seemed promising as refuges for fauna and to increase fish productivity. The author studied this alternative and after several months of preparatory arrangements a small reef was built between June and April 1984 at a depth of 10 m using approximately 400 scrap tires on the eastern shore of the Gulf of Nicoya, Costa Rica.
