4. Give an example of an invasive species that came from commercial shipping.
5. Describe how aquaculture can promote fish diseases.
6. Describe how aquaculture can promote antibiotic resistance.
7. Describe one problem caused by use of hormones in aquaculture.
8. Describe two ways aquaculture can cause eutrophication and dead zones in the ocean.
