What are the negative impacts on round goby?

The round goby has several negative impacts on the environment and native species. These impacts include:

Competition with native species: Round gobies compete with native species for food and habitat, including benthic invertebrates and small fish. This competition can lead to a decrease in the abundance of native species, which can disrupt the ecosystem.

Predation on native species: Round gobies prey on native species, including eggs, larvae, and juveniles. This predation can have a significant impact on the recruitment and survival of native fish populations.

Alteration of habitat: Round gobies can alter their habitat by creating nests in the substrate and by disturbing the benthic community. This can have a negative impact on native species that rely on specific habitat conditions.

Disease transmission: Round gobies can carry diseases and parasites that can be transmitted to native species. This can lead to disease outbreaks and further declines in native species populations.

Overall, the round goby has several negative impacts on the environment and native species, which can disrupt the ecosystem and lead to declines in native species populations.
