Abstract

The blue swimming crab (BSC) fishery is a vital source of livelihood for coastal communities throughout Bohol. This study aims to determine the status of blue swimming crab fishery, analyze the market flow, and identify the problems or challenges impacting the BSC industry. A descriptive survey method of research was used in the study with the aid of survey-questionnaires validated with personal interviews and focus group discussion. The study was conducted in Mantatao Island, Calape, Bohol for two months from November to December 2022. A total of 12 crab fishers and 1 crab trader were surveyed. Results revealed that the crab fishers in Mantatao Island employed two types of fishing methods; the traditional handpicking and spearfishing. Results also indicated that there was a decline in BSC catch coupled with a low average daily catch of 0.91 kg on November and 0.82 kg on December. The BSC products of the crab fishers are primarily distributed locally to different channels, including crab trader, local and nearby wet markets, and end consumers. Challenges identified include declining catch rates attributed to a lack of awareness among industry players regarding existing BSC fishery regulations. Despite the stability of BSC fishery in Mantatao Island, the industry faces sustainability threats. Addressing these challenges is crucial for ensuring the long term viability of the BSC fishery and supporting the livelihoods of local fishers.
