Ichthyology and GIS critical to streamlining data collection in field endeavors and generating more accurate data sets. Ichthyology requires an understanding species geographic requirements. Fish require different abiotic environments or sediments for successful completion of biological life cycle based on species. Serious examinations of species should always include habitat because habitat differences create changes in population. Sediment could thereby be mapped and changes in sediment could easily be verified using previous records while simultaneously showing changes in resident fish populations. Various factors relating to the fish life cycle, such as food sources, migration patterns, changes in spawning grounds, could all be more accurately
Ichthyology and GIS the biggest advantages in using GIS is assimilating information and using it to highlight significance or irrelevant data. Use of GIS increases the possible integration of many different types of data into a single usable resource making analysis and interpretation easier as well as increasing management of the data involved. Ichthyology is a field of study that requires active examination of a multitude of areas at the same time for accurate study. GIS programs improve spatial data aspects frequently to accurately represent substrate, habitat, quality or other various factors. This tool enables scientists to access information and share results quickly
