Collected Evidence: Collected Evidence: Include fishers in management groups for marine protected areas We found no studies that evaluated the effects of including fishers in management fora for marine protected areas on marine fish populations.  ‘We found no studies’ means that we have not yet found any studies that have directly evaluated this intervention during our systematic journal and report searches. Therefore, we have no evidence to indicate whether or not the intervention has any desirable or harmful effects.Collected Evidencehttps%3A%2F%2Fconservationevidencejournal.com%2Factions%2F2809https%3A%2F%2Fconservationevidencejournal.com%2Factions%2F2809Fri, 05 Feb 2021 10:00:36 +0000Collected Evidence: Collected Evidence: Involve fishers in designing and trialling new gear types to encourage uptake of more selective fishing gear We found no studies that evaluated the effects of involving fishers in designing and trialling new gear types on marine fish populations.  ‘We found no studies’ means that we have not yet found any studies that have directly evaluated this intervention during our systematic journal and report searches.

One study was in each of the Indian Ocean, the South China Sea (Vietnam) and the Pacific Ocean (Tonga).  COMMUNITY RESPONSE (1 STUDIES) POPULATION RESPONSE (1 STUDY) Abundance (1 study): One before-and-after study the Indian Ocean found that involving fishers and stakeholders in co-management increased overall fish abundance, but abundance varied between species groups, nine years after implementation compared to before. BEHAVIOUR (0 STUDIES) OTHER (2 STUDIES) Reduction of fishing effort (1 study): One before-and-after study in the Pacific Ocean found that in the five years after implementation of a new co-management system there was no decrease in overall fishing effort in the managed area. Commercial catch abundance (1 study): One before-and-after study in the Pacific Ocean found no increase in total fish catch rates and a decrease in catch rates of half of the six species groups individually inside an area with a new co-management system after five years. Improved compliance/reduction of illegal fishing activity (1 study): One before-and-after study in the South China Sea reported that after co-management was established in an area there was a decrease in illegal fishing using destructive fishing gears.
