Summary

The primary goal of this project was to collect up-to-date information on current socioeconomic conditions, and the spatial distribution and relative economic value of key commercial fisheries and the commercial passenger fishing vessel fleet in the North Central Coast Region.

Description

These data were developed as part of the California North Central Coast Marine Protected Area Baseline Monitoring Project that is designed to characterize the ecological and socioeconomic conditions and changes within the North Central Coast Region since MPA implementation. The North Central Coast study region extends from the south at Pigeon Point to the north at Alder Creek. These data depict the spatial change in the stated relative value of commercial fishing grounds. The data were created by calculating the difference between data collected in the summer of 2007 (pre-MPAs) and in the spring of 2010 (post-MPAs). Specifically, the data were produced by subtracting the post-MPA relative value surface data from the pre-MPA relative value surface data (x = pre-MPA - post-MPA). It is important to emphasize that only the relative value surfaces (also known as a 'heat map') were used in this analysis. In other words, ex-vessel revenue was not applied to the 'heat map' value surfaces, however ex-vessel revenue was used to weight the aggregated individual fishing grounds. This was done to reduce the number of variables which would influence analysis results. Thus, results are simply an examination of changes in the stated values/importance of fishing areas to a fishery and not spatial changes in revenue across the two datasets. The data ranges from negative to positive values on a relative scale. In this dataset the areas with negative values are areas where the post-MPA fishing relative values are greater than the pre-MPA relative values, thus an increase in relative importance and value between the 2007 survey to the 2010 survey. This dataset represents the spatial change in relative value for Urchin--dive commercial fishing grounds for the North Central Coast Region.
