Bermuda Ocean Prosperity Programme: Ocean Use Survey

Commercial Fishing Heatmaps


Commercial Fishing

  • This page summarizes the demographic data collected for the commercial fishing sector and presents the heatmaps that were created using the survey responses.
  • Note that demographic data do not reflect group responses, as those details were not collected for each person represented in a group response, just the individual interacting with the survey.

Overview

Of the respondents that drew shapes valued for commercial fishing, 23 indicated their age, with a median of 51 and a range from 19 to 73, where 19 is the minimum age and 73 is the maximum age. 96.7 % of commercial fishing respondents that indicated their gender were male, and 3.3 % were female.

To gauge the geographic reach of the survey to commercial fishers, data collected on respondents’ parish of residence was compared to lists of licensed fishing vessels in each parish. Results are shown below:

For commercial fishing, the survey also included an option to indicate what gear a respondent used in the shape drawn. The table below summarizes the number of shapes drawn for each gear type (many respondents indicated more than one gear type per each shape drawn, especially for larger areas). Different gear options were included on the two platforms, so responses have been separated into those collected on SeaSketch and those collected on Maptionnaire.

Heatmaps

This section contains the heatmaps produced from the commercial fishing responses. Heatmaps are a representation of data (in this case, data presented as a series of maps) where values are represented as colors: Hot or High Values are on the red end of the scale, while cold or Low Values are on the Blue color scale. All heatmaps in this section are sector based calculations of Use and Value produced directly from OUS responses for Commercial Fishing. Readers should be able to use these maps to learn how commercial fishers value ocean space in Bermuda.

Two online platforms were used to collect OUS responses: SeaSketch and Maptionnaire. Respondents could submit responses individually or as a group. Responses could also be given a spatial weight.

All Responses, Weighted

All Responses: Maps labeled as “all” were created using all the responses collected for the given sector from both SeaSketch and Maptionnaire

Weighted: Maps labeled “weighted” were created by dividing the value assigned to a shape by its area in km2, and then summing the total value per pixel across all respondents for a given sector. High value areas (red) therefore reflect areas chosen by many respondents as well as areas that respondents value particularly highly.
