MMO1044 predicted life stages and habitat distribution of fish species in the south marine plan area
This data represents the presence and absence of various life stages of fish species and the relative confidence of the probability based on the outputs of statistical modelling. Confidence is rated as High - 3 - 25 percent misclassified overall, Moderate - 2 - 50 percent misclassified overall Low - 1 - more than 50 percent misclassified overall.

This data was created as part of the MMO1044 report "Spatial models of essential fish habitat (South Inshore and Offshore marine plan areas)" it should be used within the context of the report. The aim of the project was to improve the spatial resolution of data on essential fish habitats for key fish species (both of commercial and ecological relevance) in the South Inshore and South Offshore marine plan areas, and to assess the relative value of these fish habitats to the regional commercial fisheries productivity and the ecosystem function. The report's recommendations were formulated on how to address the limitations in future studies to allow improvement of the methodology and its application. For the complete methodology and the report findings please refer to the report and technical annexes: http://webarchive.nationalarchives.gov.uk/20140108121958/http:/www.marinemanagement.org.uk/evidence/1044.htm Habitat categories are: 1. Absence, 2. Adults, 3. Adults and Juveniles and 4. Outside Model Range. Probability of juvenile or spawning presence is catagorised as: 0-25% - Absence 25-50% - Absence 50-75% - Presence 75-100% - Presence -9999 - Outside Model Range. Caveats: • A total confidence value (see Final Report) and a relative confidence layer are associated to these data. These should be always considered when using these data. These data should not be used in isolation when the total confidence is low or where the relative confidence shown in the confidence layer is lowest. • Their validity of the EFH outputs is related to a specific season depending on the data used to calibrate the models (summer for the adult foraging and nursery habitats; winter for the spawning habitats). This temporal aspect should be taken into account when interpreting or validating the data. Also, the EFH distribution is predicted based on average environmental conditions referred to the years between 2000 and 2012. Therefore a certain variability in the species habitat distribution is to be expected compared to the maps when considering other seasons or specific years. • As no pressures or impact data data were included in the models, the EFH maps should be interpreted as potential distribution of species EFH.
