What is the ecological impact of overfishing?
- Extinction of some species of fish.
- Reduction of the population of adult reproductive fish, leaving a population of mainly young individuals because fish are caught as soon as they reach catchable size.
- It may lead to rapid increase in the numbers of fish prey organisms.
- May lead to reduction or even extinction of some aquatic fish predator organisms which may then encroach on terrestrial habitats near water bodies. For example, crocodiles may start hunting terrestrial animals that come close to the water bodies including man.
- Disruption of aquatic food webs.
