Catching fish from the oceans is not considered illegal, so long as it doesn’t lead to overfishing—i.e., the use of vehicles that catch fish at a much faster rate than the stocks could be replenished. Overfishing can put the life of certain aquatic species in danger. It also explains the growing cases of extinction. Overfishing is also related to bycatch, in which people capture aquatic animals unintentionally. Basically, they aim to catch certain species but end up catching unwanted animals.
This is quite common when large vehicles that catch hundreds of fish at once are used for fishing. It is one of the most common overfishing problems that has led to the loss of billions of fish species. Not only fish, but people end up killing sea turtles and other animals that are of no use to them. With the overfishing problem causing severe destruction to marine life, it is important that the government and scientists take important steps for the preservation of fish. The question is how is overfishing discovered and what can be done to prevent it.
GIS in Overfishing
Global Fishing Watch has become a popular tool of the GIS, allowing people to watch out for the fishing activities taking place in the ocean. Anyone who has access to the internet can use this tool for monitoring fishing activities across the world. It is most commonly used for disclosing marine areas. The data is available for companies exploring the fishing sector. Basically, these tools show whether or not the fishing sector is following the latest government regulations concerning fishing. It tells whether the fishing companies are relying on the latest government rules for conducting fishing activities.
The main purpose of the tool is not only to give people a detailed insight into how fishing is conducted but show how overfishing problems can be resolved. Another goal of using GIS for monitoring fishing activities is to ensure sustainable practices. The biggest problem with overfishing is that the recovery of the species is pretty difficult once the fishing company ends up collecting a large number of these aquatic animals from the oceans.
Destruction Due to Bycatch
Not only do they destruct the marine environment, but they cause extinction and lead to a large number of endangered fish species. In Bycatch, even if people drop the unwanted aquatic animals back into the water, there is a very slim chance they will return uninjured and healthy. Most aquatic animals end up dying during the process. In fact, a quarter of the marine animals caught during fishing represent a bycatch. It clarifies that hundreds of thousands of fish species die because of the inappropriate fishing process. This is especially true for the shrimps. When capturing shrimps, people catch a large number of other species in the process.
There is no denying that overfishing leads to the sudden depletion of fish. And, recovery from that is quite hard since a considerable volume of fish and other aquatic animals are destroyed during the process.
