200 million people work in and around global fishing operations, and the outcome provides vital protein for over a billion people. The environmental impact of overfishing is severe as smaller fish, not yet able to breed are caught prior to them growing into a size large enough to produce substantial fish families. Because 77% of species are overfished now, and more on the way to extinction the economic impact for local and large economies will continue to bring big losses.
Managing Marine Protected Areas bring scenarios of 98% fish stocks being rebuilt by 2050 IF we quickly reform our protective actions.
71% of MPAs positively influenced fish populations. However, impacts were highly variable from lack of staff and budget capacity, brought far less growth. MPAs with adequate staff capacity had ecological effects 2.9 times greater than MPAs with inadequate capacity. Thus, continued global expansion of MPAs without adequate investment in human and financial capacity is likely to lead to sub-optimal conservation outcomes.
