A review of small-scale fisheries of marine crustacean is here presented, indicating the main biological traits of the target species, levels and methods of capture, prices and markets, as well as fishing regulations. Edible barnacles are exploited in Spain, Japan, and Chile with low levels of capture (<500 t per year) and can be sold at high prices in the Iberian market. Stomatopods (mantis shrimps) are captured in the vicinity of the river mouths through trawl fisheries in Mediterranean Sea and in the western Indo-Pacific. Their landings fluctuate between 4,000 and 7,000 t per year, with levels of overexploitation reported for some Asian fisheries. A recent harvesting of sandhoppers (amphipods) has been reported from sandy beaches of Chile for aquarium food, with annual yields of 10–15 t dry mass. Other amphipod species (lysianassoids) are exploited in Canada mainly for fish food. These fisheries are characterized by a lack of biological and fishing parameters, management measurements, and regulations of the exploitation of their natural populations. However, in the cases of the European fisheries (stalked barnacles and stomatopods), some regulations have been implemented, such as closing periods, extraction quotas, and minimum legal sizes. Ecological studies are necessary to evaluate the possible impacts on biological interactions and food webs on the populations of the commercial extraction in these fisheries.
