Native fish populations will decline and possibly become extinct as they compete for food and space.

Explanation:

The invasive species is the one which compete for resources with the native species. Such species may be introduced accidentally or due to human intention to a new habitat.

The long term consequence can be define as the impact of a biotic or abiotic factor on the environment which leads to the extinction of species and makes the environment unsuitable for survival of new organisms for long time.

Due to introduction of catfish which is an invasive species, the native species population will decline and extinct due to competition with native species. Hence, it can be considered as a long term consequence of introduction of catfish.
