Long-term monitoring informs data-poor marine species in the northern Gulf of Mexico

Abstract

Fisheries monitoring programs around the world are often designed to provide information on a wide range of species that come into contact with the program gear(s). Such programs may provide untapped abundance and distribution data for species of greatest conservation need (SGCN) and other rare or data-deficient species. We examined >30 years of fish sampling data from coastal Louisiana and found that 13 of 18 SGCN marine fishes were represented in existing routine monitoring data. Although some species were rarely reported, >100 records were available for seven species, with some species being reported several thousand times. Using these records, we were able to provide species-specific information about gear, season, location and timing for several marine fishes that were considered largely unknown. Given the paucity of information available for these species and the rapidly changing Louisiana coast, these biogeographic data may be important in the development of future conservation and management programs.
