Demersal Fish Community - spatial variation in size, species richness and diversity
What is it:
The three layers show the spatial variation of demersal fish (generally living on or near the seabed) in waters around Scotland (averaged over the period 1999 to 2008) for:
- Size Composition (Large Fish Indicator) (defined as the proportion of fish (by weight) in the community that is greater than 40 cm in length). The higher the value (varying between 0 and 1), the greater the proportion of large fish in the community.
- Species Richness (a count of the number of demersal fish species recorded in any survey sample).
- Species Diversity (indices that also take account of the relative abundance of each species in the sample).
Date of Data: 1999-2008.
