What percentage of fishing is bycatch?
According to bycatch as defined in this report and elsewhere, the most recent analyses show a rate of approximately 10% (Zeller et al. 2017; FAO 2018). In the United States, despite strong management measures and conservation initiatives in some regions, bycatch remains a persistent problem for far too many fisheries.
What percentage of fish are being overfished?

2020, shows that on average, scientifically-assessed fish populations around the world are healthy or improving. 2020 counters the perception that fish populations around the world are declining and the only solution is closing vast swaths of ocean to fishing.
How much has the fish population decrease due to overfishing?
It seems that even their high reproductive rates can’t compete with the rate of overfishing. The greatest declines were found in the southern temperate and polar Indian Ocean and the southern polar Atlantic. Since 1950, fishery populations there has shrunk by over 50 percent.
What percent of the world’s fisheries are fully exploited?
Overall, 80 per cent of the world’s fish stocks for which assessment information is available are reported as fully exploited or overexploited and, thus, requiring effective and precautionary management.
