With a large number of fish species becoming extinct due to climate changes and human exploitation, scientists and researchers are now more concerned about ecology conservation. Using GIS (geographic information system), people have been able to identify different species of fish in the oceans and come up with ways to protect them. Scientists’ efforts are on developing techniques for the protection of biodiversity. GIS does a lot more than enable researchers to collect in-depth information about the fish species and their movements. The technology has made it possible to identify the leading causes of fish eradication and develop plans for conserving these marine animals.
The biggest issue that researchers were facing was the lack of labor, time, and budget for the biodiversity protection project. It wasn’t possible to conduct research on marine life over the vast oceans, which is why they came up with the GIS tools. These tools have become quite popular in managing marine resources and conducting biodiversity conservation planning. Thanks to these tools, it could have never been possible to predict aquatic communities.
Role of GIS in Fish Conservation
The GIS networks allow research communities to understand aquatic life and detect fish species' presence. In addition to that, these techniques should give reliable information about the connection between different species of fish, aquatic life, the impact of weather, and most importantly, the changes in sea level. All these factors affect the habitat of fish and their population significantly. In fact, one of the reasons for the decreasing population of sharks and whales in the oceans is the extreme fluctuations in climate. It is believed that changes in the climate and temperature play a pivotal role in establishing the environment for these aquatic species.
Another important factor causing the eradication of certain fish species is the growing level of marine pollution. There are multiple reasons that can be blamed for sea contamination, including but not limited to, inappropriate land use and exploitation of fish species by humans. Even though most states have made fish hunting illegal, especially for certain species, it is still conducted on a large scale in many nations. In addition to that, sharks and other aquatic species remain exposed to other wild marine animals. Pollution, exploitation, and climate changes can have a detrimental impact on fish habitats. It also explains how the population of fish has reduced to a few thousand species left in the vast oceans.
With the help of satellite imagery and other remote sensing tools, scientists have been able to track the movements of fish effortlessly. The best part is that some tools are implemented on the fish, helping scientists get a clear picture of their movements and the factors affecting their habitat and survival in the ocean. Based on this data, they can make accurate predictions regarding the factors that might influence the population of aquatic animals in the future and what can be done to conserve these species.
