What's the harm of scavenger fish?

Scavenger fish, also known as bighead carp and lobster fish, is a large carnivorous fish. Although it tastes delicious, its existence has caused some potential harm to the environment and human health.

1, which is harmful to marine ecology

Scavenger fish is a carnivorous fish, eating many small fish, shrimps and crabs in the ocean. Excessive predation will lead to the disorder of marine ecology and the collapse of ecological chain. In addition, scavenger fish will take the initiative to look for carrion and waste on the seabed and clean it up, which should have been decomposed by other marine organisms, thus promoting the operation of marine circulation.

2. Potential harm to human health.

Because scavenger fish's living environment is polluted, the content of harmful substances in his body is relatively high. If people eat too much scavenger fish, they may ingest too many harmful substances, which may cause potential harm to human health. In addition, scavenger fish may ingest viruses, bacteria and other harmful substances in the process of searching for carrion, which increases the risk of human infection.

3. This has a negative impact on fishery resources.

Scavenger fish's meat is delicious, so it is sought after by commercial value. However, its number is not abundant, and overfishing will reduce its number and even be on the verge of extinction. At the same time, the fishing of scavenger fish may affect the development of other fishery resources and the whole marine fishery.

4. It has a negative impact on tourism resources.

Some tourist areas in tropical seas will suffer environmental damage due to scavenger fish. If scavenger fish is overfished, it will break the local ecological balance and make the whole tourism environment desolate. People who come to these places for sightseeing or diving will be disappointed with the destruction of scavenger fish, thus reducing the income of tourism.
