Is overfishing reversible?


The effects of overfishing are still reversible by implementing sustainable fisheries policies: Safe catch limits – a constantly reassessed and scientifically determined limit on the total number of fish caught and landed by a fishery; politics and short-term economic incentives should have no role in this.

How is overfishing solved?

Key factors include enforcement of regulations, up-to-date data collection, and monitoring of fish stocks. Fishermen and their communities benefit from well-managed fisheries too because they’re more lucrative and reliable.

What is systemic overfishing and how can we stop it?

Systemic overfishing is only made worse by illegal catches and trade. In fact, some of the worst ocean impacts are caused by pervasive illegal fishing, which is estimated at up to 30% of catch or more for high-value species. Experts estimate illegal, unreported, and unregulated (IUU) fishing nets criminals up to $36.4 billion each year.

What is the best way to solve the problem of overfishing?

However, overfishing may very well be the easiest problem to address. Many fish populations could be restored with aggressive fisheries management, more stringent enforcement of laws governing catches, the increased use of aquaculture or Ocean Seeding.
