| Occurrence of Atlantic Sharpnose Shark (Rhizoprionodon terraenovae) from SEAMAP and
NMFS SEFSC Fishery-Independent Resource Surveys |
 |
Fisheries-independent catch and effort data from Southeast Area Monitoring and Assessment
Program (SEAMAP) Summer and Fall Groundfish Surveys (from 1987 to 2018) and National
Oceanic and Atmospheric Administration (NOAA) National Marine Fisheries Service (NMFS)
Southeast Fisheries Science Center (SEFSC) Bottom Longline Surveys (from 2001 to 2018)
are used to map the occurrence of Atlantic shaprnose shark (Rhizoprionodon terraenovae)
in the northern Gulf of Mexico. The final summary is represented as a point layer.
The layer attributes include the longitude (LON) and latitude (LAT) of each station,
the presence or absence (OCCURRENCE) of the species and the survey (SURVEY) during
which it was taken. Juvenile, and some adult Atlantic sharpnose shark are caught during
SEAMAP Summer and Fall Shrimp/Groundfish trawl surveys. Adult Atlantic sharpnose shark
are primarily observed/taken during NMFS SEFSC Bottom Longline surveys. |
