The ecology of fish on marine sand: Implications for fisheries and marine protected area management

Play Video





1. Summary

Marine soft sediments make up vast areas of the sea floor and marine protected areas (MPAs) cover large areas of this soft sediment habitat. In contrast to other systems very little research has examined the ecology of demersal fishes (that is fish found on the sea floor) found on marine soft sediments within MPAs. Even fewer studies have investigated changes in marine soft sediment fish communities when fishing is removed in no-take zones. In addition, the movement of demersal soft sediment fish has rarely been investigated. This poses challenges for management and the evaluation of the efficacy of marine protected areas, in which soft sediments often make up more than 70% of habitats.
