5 Worst Invasive Fish Part 4

What are the worst invasive fish species? In this video I will be trying to that question and many others you may have about invasive fish species. An invasive species is any plant or animal that has be introduced into an ecosystem where it doesn't belong, normally having negative impacts on native animal and plant species. Invasive fish don't only endanger native fish species but they can also cause millions of dollars worth of damage.

Our first problem invasive fish species the largemouth bass. The largemouth bass is one of the most popular game fish in north America but when it is imported to countries outside of it's native range then it can become a problem invasive species.

Our next invasive fish species is the climbing perch. Although the climbing perch is a small fish, it is almost the perfect model for a successful invasive fish species as it is very adaptable and can travel short distances on land.

Our next Invasive fish species is the channel catfish. The channel catfish isn't the largest catfish in north America as the flathead catfish and the blue catfish are larger but it is the most numerous catfish in north America. This catfish has been imported to Europe where it feeds on the smaller native fish.

Our Forth invasive fish species is the pacu. There are a few species of pacu but they are all related to the piranha. Pacu have become invasive in the USA as they are often kept as pets and released into the wild.

Our last invasive fish species is the pink salmon. The pink salmon is a pacific species of salmon but has been introduced into Russia and has since spread into other European countries. This salmon invasion puts pressure on the native salmon.

What do you think is the worst invasive fish species?
