Mangrove crab aquaculture practices and challenges: The case of Capalonga, Camarines Norte, Philippines
Abstract
Mangrove crabs (Scylla spp.) are economically important aquaculture commodities and a source of livelihood, particularly in impoverished coastal communities. However, the aquaculture practices and challenges of small-scale mangrove crab farmers in poor coastal areas are often overlooked and poorly understood, exposing them to a higher risk of economic loss. This study assessed the current mangrove aquaculture practices and challenges in Capalonga, Camarines Norte. A mixed-method research approach combining descriptive surveys and focus group discussions was employed to gather data from all crab farmers (n=42) in the study area. Results showed that most participants, ages 30 to 70, were dominated by males (76%) and practiced only grow-out culture, with Scylla serrata as the preferred culture due to higher economic returns. Despite its economic potential, it is confronted with numerous challenges, including changes in weather conditions and natural disasters, disease outbreaks, limited technical knowledge, a lack of government intervention, and quality seed scarcity. These problems underscore the imperative need for targeted interventions such as the provision of training and technical support for the crab farmers, the establishment of a local hatchery, disease management, and the inclusion of the study’s findings in local management plans to enhance the sustainability and profitability of mangrove crab aquaculture in Capalonga.
