Applied interpolation methodology with GIS used for artisanal fishing zoning in Bahía Magdalena, Mexico

Abstract

Objective: To limit the artisanal fishing zones in the water mirror of Magdalena Bay, by means of interpolation.

Design/methodology/approach: Through surveys, social, economic and biological production data, wich are collected from a sample of 56 artisanal fishing cooperatives. The data is integrated into a relational database with geospatial reference and geostatistically processed with interpolation methods using a geographic information system.

Results: Four zoning maps based on the interpolation of the variables target species, fishing effort, extraction volume and sale value.

Limitations on study/implications: The remoteness and difficult access to the study area.

Findings/conclusions: The methodology can be used at the national level and generate a limitation of the priority zones for artisanal fishing in Mexico, contributing to decision making and management plans that can consider the variables of the fishermen's social life.
