Why is overfishing a problem in Australia?
Overfishing has already decreased part of Australia’s fish stocks to dangerously low levels. Two major factors account for this problem; the fact that some areas have low biological productivity (and hence fish stocks do not regenerate quickly), along intensive fishing efforts by commercial and recreational fisheries.
