Title

2013 - 2015 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Scores representing Magallana gigas (Pacific oyster) environmental suitability and introduction / spread risk for UK waters based on data from 2013 to 2015.

Abstract

Data are scores calculated in 2020 to indicate the environmental suitability and risk of introduction into, and secondary spread of *Magallana gigas** in UK waters. Scores are calculated for each **cell of a grid based on ICES statistical rectangles split into *sixteenths for the geospatial extent of UK waters.

Lineage

The grid was based on ICES statistical rectangles split into sixteenths. Grid cells were attributed a ‘larval settlement’ score for four scenarios by summing maximum (across years 2013, 2014 and 2015) particle tracking settlement scores falling within the cell. Similarly, grid cells were attributed a ‘suitability’ score by summing environmental suitability scores falling within the cell. For each grid cell, the larval dispersal connectivity score was multiplied by the suitability score to provide an estimated risk score of introduction or spread score. Risk scores were scaled between 0-100 and divided into very low, low, moderate, high and very high categories based on the scaled score thresholds; <1, 1-4.99, 5-24.99, 25-49.99, >50 .
