Action: Cease or prohibit the harvest of conch
Key messagesRead our guidance on Key messages before continuing
- We found no studies that evaluated the effects of ceasing or prohibiting the harvest of conch on their 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.
Conch populations have significantly declined due to overharvest, for commercial and recreational purposes (Theile 2001). Bylaws, legislation, or voluntary agreements could be established which prohibit the harvest of conch in an area, in order to reduce the pressure on conch populations and in theory allow the population to recovery naturally.
When this intervention occurs in a marine protected area, the evidence is summarised under “Habitat protection – Designate a Marine Protected Area and prohibit harvest of conch”.
