Reef Fishes at All Trophic Levels Respond Positively to Effective Marine Protected Areas
Marine Protected Areas (MPAs) offer a unique opportunity to test the assumption that fishing pressure affects some trophic groups more than others. Removal of larger predators through fishing is often suggested to have positive flow-on effects for some lower trophic groups, in which case protection from fishing should result in suppression of lower trophic groups as predator populations recover...

متن کاملCoral reef fishes exhibit beneficial phenotypes inside marine protected areas
Human fishing effort is size-selective, preferentially removing the largest individuals from harvested stocks. Intensive, size-specific fishing mortality induces directional shifts in phenotypic frequencies towards the predominance of smaller and earlier-maturing individuals, which are among the primary causes of declining fish biomass. Fish that reproduce at smaller size and younger age produc...
متن کاملConservation Biology: Strict Marine Protected Areas Prevent Reef Shark Declines
Populations of two coral reef shark species are declining rapidly: the pattern of decline highlights both the substantial impact of poaching on closed areas and the success of strict no-entry marine protected areas in maintaining healthy shark populations.
متن کاملToward pristine biomass: reef fish recovery in coral reef marine protected areas in Kenya.
Identifying the rates of recovery of fish in no-take areas is fundamental to designing protected area networks, managing fisheries, estimating yields, identifying ecological interactions, and informing stakeholders about the outcomes of this management. Here we study the recovery of coral reef fishes through 37 years of protection using a space-for-time chronosequence of four marine national pa...
