Researchers are aware of the connection between the GIS tools and the identification of fish species. With the help of remote sensing technology, people have been able to identify different species of fish in the oceans. One such technology that has been gaining immense attention lately is the fish habitat model. As you might have guessed from the name, it enables researchers to identify the fish habitat in different flow conditions.
The concept includes mainly three aspects, which tell you about the availability of fish habitat in the river. It involves biological sampling, hydraulic modeling, and surveying. The sampling is used to link the fish species with the flow and river conditions. It helps scientists identify the habitat condition in terms of velocity, as well as, the depth of the river. Basically, the hydraulic modeling and biological sampling are conducted and the outcome of each is used in conjunction in order to calculate the hydraulic habitat for individual fish species. This is done at different flow streams.
How to Use GIS for Identifying Fish Habitat?
GIS tools are also used for identifying the habitat for fish, which is later used for making decisions. Note that the tool can only help you detect the fish habitat in places where velocity and depth criteria are used for conducting in-depth research on the fish habitats. As the concern around the environment and sustainability is growing at a rapid pace, people have become more conscious about the environment.
Researchers have implemented a wide range of techniques and tools to identify the causes of water pollution in remote and inaccessible areas. With the help of the GIS tools, it has become possible to not only identify different species of fish in the river but figure out habitat for them. This is called the instream flow. Maintaining a sound environment has become a top priority of environmentalists. It is important to maintain the diversity of aquatic species. As mentioned above, three main techniques implemented for the identification of habitat for fish species are hydraulic modeling, biological sampling, and habitat modeling.
The main purpose of this research is to identify the condition and environment in which the different species of fish live. This is done to ensure whether aquatic life is healthy, which species are close to extinction, and what factors affect their life in the water. This mainly includes the description of the depth, velocity, and temperature of the area. As mentioned above, the results of the two methods—sampling and hydraulic modeling—are combined to identify the living conditions of the fish species under different flow streams.
GIS tools have become a prominent technology in the identification of the habitat for fish species. The primary goal of the technology is to help researchers access the areas that can’t be reached manually. Besides, locating the inflow streams, as well as, fish habitats is not possible if you execute the research work on your own, especially in the hard-to-reach areas. That is where the satellite-based images showing you a clear and detailed picture of marine life come into play.
