It helps identify high conservation value areas for essential fish habitat (EFH). Additionally, it allows users to incorporate stakeholder input and expert knowledge into the study area while continuously monitoring & updating GIS data to improve model accuracy.
3. Habitat Suitability Modeling With GIS
Habitat suitability modelling with GIS involves using statistical techniques to predict the likelihood of a particular area being suitable for fish habitat by creating maps of important factors like water depth, temperature, and substrate type.
This process helps to identify areas that require restoration or conservation efforts. Accurate data collection and appropriate modelling techniques are essential when using GIS for fish habitat analysis. The generated models can provide insight into the distribution patterns of species present in the study area.
GIS is essential for fisheries management and ecology studies, enabling researchers to explore different scenarios and make informed decisions about nature conservation and biodiversity. Combining remote sensing satellite imagery with biological data makes it possible to accurately assess essential fish habitats (EFH).
Spatial analysis is another useful technique that helps researchers identify areas suitable for specific fish species. Overlay analysis combines different data layers to identify areas most conducive to a particular species.
