Stock Assessment of Octopus in Four Regions of the Philippines and Nationally

Abstract:

Scientific stock assessment is a key bio-mathematical tool in the understanding of the population dynamics of fished stocks, estimation of their productivity and establishment of management programs aimed at their sustainable exploitation. Octopus fisheries are a special case because octopus stocks are short-lived, with fast dynamics, and their exploitation is usually conducted by small-scale fisheries. Thus data collection tends to be deficient, making them data-poor or data-limited fisheries that require specialized tools for their assessment. This scientific report collect data from the four Philippine’s selected regions and the national total were analyzed to determine the abundance and exploitation status of the octopus stock.
