Fishing cooperatives’ participation in managing nearshore resources: the case in Capiz, central Philippines -
Fisheries Research, 2004 - ElsevierThis study documents the resource management initiatives undertaken by fishing cooperatives in Capiz, central Philippines and examines the conditions and the socioeconomic determinants that persuade members to assume responsibility for managing nearshore resources. The results show that in the absence of formal resource management schemes, cooperative members adopt self-management strategies to protect their resource base only if the sustainability of their livelihood is seriously threatened. There is no impediment to female cooperative members (62%) participating in resource management. The factors that positively influenced members’ participation were the number of children, perceived fishery conditions, awareness of mangrove conservation and rehabilitation, and assessment of enforcement of the ban on dynamite and cyanide fishing. Fishing cooperatives, however, fail as a source of information on regulation and conservation education of members. But if they were to undertake more education and training programs on nearshore management, cooperatives may become an effective social force in changing the present fisheries management system.

- Small-scale fisheries are an important element of the ecosystem goods and services that mangrove habitats provide, especially to poorer coastal communities that rely most on natural resources, and have similar values to payments for ecosystem services (PES) under carbon-trading schemes.
- In advance of fishery-enhancement trials for the mud crab Scylla olivacea, a mark–recapture study was conducted to estimate population size and turnover in 50 ha of isolated mangrove on Panay Island, Philippines. A total of 811 crabs were released in six sessions with an overall recapture rate of 41.5 ± 3.6%. Population size ranged from 607–1637 individuals.
- There was a high degree of site-fidelity, with 45.5% of recaptures in the same sampling areas as releases. Total mortality was 0.79 month-1, with fishing mortality accounting for 95% of overall mortality.
- Von Bertalanffy and Gompertz growth models yielded estimates for L∞ (carapace width) of 117.3 ± 14.7 and 110.6 ± 2.1 mm and for k of 2.16 ± 0.74 and 3.25 ± 0.81, respectively. Crab densities of 12–33 individuals ha-1 in the study area were lower than in other mangrove systems owing to intermittent recruitment, while growth rates indicated no limitation in terms of food supply.
- The study demonstrates that in specific mangrove habitats that are below carrying capacity, there is potential for fisheries enhancement to sustain or increase direct economic benefits from mangrove ecosystems and hence promote community engagement in broader conservation and PES initiatives.
