dc.description.abstractSEA URCHIN (LOXECHINUS ALBUS) IS ONE OF THE MOST ECONOMICALLY IMPORTANT SPECIES IN THE NORTHEAST OF CHILEAN PATAGONIA, FORMING PART OF THE HIGHLY DIVERSE BENTHIC COMMUNITY. THIS RESOURCE IS BEING HARVESTED UNDER SELECTIVE FISHING PRESSURE, WHICH SUPPRESSES GROWTH RATES. IN RESPONSE, THE NATIONAL STANDARDS INSTITUTE ESTABLISHED REGULATION 44 AS A QUALITY CONTROL MEASURE, BASED ON A SAMPLING APPROACH CONSIDERING THE PERCENTAGE OF SEA URCHIN UNDER THE MINIMUM LEGAL SIZE (UMLS) THROUGH AN ACCEPTANCE SAMPLING PLAN. IN 2019, THE CHILEAN UNDERSECRETARY OF FISHERIES AND AQUACULTURE (SUBPESCA), UNDER EXEMPT RESOLUTION NO. 910, RULED THAT ANY VESSEL THAT LANDED 15% WITH SEA URCHIN OF 6.5 CM UMLS OF THE TOTAL CATCH WEIGHT WILL BE SANCTIONED. IN THIS PAPER, A SAMPLING DESIGN IS PRESENTED TO ESTABLISH CRITERIA REGARDING COMPLIANCE WITH THIS PROVISION. THE PLAN PROVIDES A STATISTICAL METHODOLOGY FOR THE EVALUATION OF THE PERCENTAGE OF UMLS SEA URCHIN, WHICH CORROBORATES AND CERTIFIES THE CURRENT LEGISLATION THAT SANCTIONS AND FINES THE CAPTURE OF SEA URCHIN THAT DOES NOT COMPLY WITH UMLS VALUES OUTLINED IN REGULATION 44. ASSUMING A SYSTEMATIC SAMPLING PLAN AND UNDER ASSUMED UMLS VALUES OF 6.0, 6.5, AND 7.0 CM, IT IS DETERMINED THAT 15% OF TOTAL LANDINGS (MARGIN OF TOLERANCE) OF SEA URCHIN UNDER 6.5 CM IS THE OPTIMAL LEVEL. THUS, A CORRECT SPECIFICATION OF THE UMLS ALLOWS PROTECTING THE MOST VULNERABLE FRACTION OF THE POPULATION FROM OVEREXPLOITATION FOR GROWTH.
