The best estimates by scientists place the number of fish in the ocean at 3,500,000,000,000. Counting the number of fish is a daunting and near-impossible task. The number is also constantly changing due to factors such as predation, fishing, reproduction, and environmental state.

What happens if we stop fishing?
Corals would get some respite
Fishing affects the whole ecosystem and, as such, reef fishing has had a huge impact on some of the most vulnerable marine ecosystems – corals. Banning fishing could not only relieve pressure on some of the 4,000 fish species that live around coral reefs, but also on the corals themselves.
Will fish bite again after being caught?
But not all fish have the same ability to remember. Species such as northern pike and bluegill are known as poor learners and often will strike again only minutes after being caught and released. Other fish, such as largemouth bass, channel catfish, stripers and carp, have better memories.
