Using lessons learned from a multidecadal intercept survey of Puerto Rico spear fishers to improve data collection in the U.S. Caribbean

Abstract

AbstractObjectiveSpearfishing is a common activity used to harvest coastal marine species worldwide and can be a significant contributor to landings of ecologically and economically relevant species. As such, it is important to monitor spearfishing catch and effort. Spearfishing is commonly practiced throughout the Caribbean, yet characteristics of this gear's fishery remain understudied in the region. Thus, the objectives of this study were to provide a description of the Puerto Rico spearfishing fishery utilizing a long‐term MRIP APAIS data set, examine the data set quality of this survey, and provide suggestions to improve MRIP implementation in the U.S. Caribbean.MethodsWe described the Puerto Rico recreational spearfishing fishery using a multidecadal (2000–2015) Marine Recreational Information Program (MRIP) Access Point Angler Intercept Survey conducted along the coast of Puerto Rico and surrounding territories. Data issues were identified in the survey results, including possible errors in measurement and identification; therefore, we limited analyses to species composition, enumeration, and mean catch rates.ResultThere were 89 species identified, with snappers (family Lutjanidae) being the most encountered family. Other economically relevant finfish frequently reported were Hogfish Lachnolaimus maximus (n = 121), Queen Triggerfish Balistes vetula (n = 115), and Red Hind Epinephelus guttatus (n = 90). Multiple reef fishes were landed during their spawning season, while prohibited by seasonal closures. Further, spearfishing accounted for 25.8% of the total harvest throughout the study period.ConclusionOur results suggest that spearfishing could be a considerable contributor to finfish landings in Puerto Rico, warranting its continued and improved monitoring in the region. Further, modifications in the design of fisheries surveys are warranted. We suggest increasing the allocation of resources, training, data quality assurance and quality control, and funding for the MRIP to maximize the accuracy of data obtained and meet MRIP U.S. Caribbean priorities. Implementation of a recreational fishing license would assist by creating a registry to monitor total recreational fishing effort and by generating funds to supplement the MRIP. The use of electronic reporting can help mitigate discrepancies with species identification and size measurements and enhance overall recreational fisheries data collection.
