Abstract

Achieving an equilibrium within the harvest of keystone species is a delicate balance especially within highly competitive tropical reef environments where conditions fluctuate. Organisms that adopt slightly flexible life histories like Caribbean Parrotfish (Scaridae) can help us acknowledge how population dynamics shift in the face of selective fishing pressures. But as of presence there is little focus in the literature on quantifying the rate of harvesting and the correlative effects it has on the local population. Here, we systematically reviewed 164 studies to find consistent relationships between the level of fisheries harvest and fish abundance, terminal phase adults and sex ratios. Across the entire Caribbean region selective fishing has reported to make large individuals rare with the exception of MPA and characteristic species like Scarus Coelestinus locally extinct and exceptionally rare in selected locations. We anticipate that this work contributes to future discussions surrounding the ICUN classifications of the Scaridae family especially in conjunction with changing fishery regulations. As, understanding the current state of parrotfish populations can ensure both resilient stocks and ecosystem services for the future.
