Popis: This fishery was examined utilizing public records,stakeholder interviews,and operational site visits to describe the fishery for the Puerto Rico Coral Reef Advisory Committee as a first step toward development of policies for the effective management of these natural resources.The fishery is not large,including fewer than 20 licensed fishers operating primarily on the west end of the island.Only three operators export product,with the remaining fishers providing specimens to the exporters based upon customer orders.Most collection of coral reef species occurs over hard rubble zones mixed with relic reef structures and rock,or on the sides and frontal areas of active reefs.Other species are collected from among mangrove prop root zones,tidal flats,and seagrass beds.Collections are made using simple barrier and dip nets for fish and motile invertebrates such as shrimp. Invertebrates such as crabs,starfish,and sea cucumbers are commonly collected by overturning small rocks, gathering the specimens,and then replacing the rocks in their original positions.Specimens are carried to the boat and transferred to individual cup holders to maximize survival.Although statements concerning former use of chemicals to assist capture were noted,no evidence of current chemical use was observed.Specimens are held in re-circulating seawater systems onshore until collections are aggregated and shipped.The fishery strives to operate with mortality of 3%are described as unacceptable to customers.More than 100 fish species are collected in this fishery,but the top ten species account for >70%of the total numbers and >60% of the total value of the fishery,with a single species,Gramma loreto (Royal Gramma),comprising >40%of the numbers. More than 100 species of invertebrates are collected,but this fishery is also dominated by a handful of species,including anemones,hermit crabs,turbo snails,serpent starfish,and feather duster polychaetes.Se estudió la pesquería de peces e invertebrados para acuarios,por comisión del Comité Consultor de Arrecifes Coralinos de Puerto Rico.Se usaron registros públicos, entrevistas con empresarios y pescadores,y visitas a los sitios de operación.La pesquería no es grande:menos de 20 pescadores con licencia que operan principalmente en el extremo occidental de la isla.Únicamente tres exportan el producto,el resto provee especímenes a los exportadores según la demanda.La captura de peces se da principalmente en zonas de escombros coralinos mezclados con restos arrecifales y roca,o en los lados y áreas frontales de arrecifes vivos.Otras especies son recolectadas entre las raíces aéreas de los manglares,zona intermareal y "pastizales " marinos.Se utilizan chinchorros y redes de mano para peces e invertebrados móviles como el camarón.Cangrejos,estrellas y pepinos de mar,así como otros invertebrados,son recogidos comúnmente volcando rocas pequeñas,sacando los individuos y después colocando las rocas en su lugar original.Los especímenes son llevados al bote y se transfieren a envases individuales para aumentar la supervivencia.Aunque existen informes previos de captura con sustancias químicas,no se observó ninguna evidencia en esta ocasión.Los especímenes se dejan en sistemas de recirculación de agua en la costa hasta el día del embarque.La pesquería se esfuerza en mantener índices de mortalidad
