Effect of Climatic Change on the Harvest of the Kelp Macrocystis pyrifera on the Mexican Pacific Coast
Abstract:The effect of sea temperature, sea level, upwelling, and wind speed on the Macrocystis pyrifera harvest was evaluated using historical harvest data for the western coast of the Baja California Peninsula, Mexico. The relationship between the environmental variables and harvest per unit effort (CPUE) was determined through correlation analysis for the period from 1956–1998. The effects of temperature, upwelling, and sea level were inverse, whereas the effect of wind speed was not significant. Multiple regression analysis showed that, of the variables studied, temperature best explained variations in Macrocystis harvest.
