Southeast Fisheries-Independent Survey (SEFIS) NOAA ship PISCES cruise number PC-18-04 from 06/25/2018 to 07/23/2018

The NOAA Ship Pisces departed from Morehead City, NC, on 25 June 2018 for a Southeast Fishery-Independent Survey (SEFIS) research cruise in continental shelf and shelf-break waters off North and South Carolina. SEFIS was created by the National Marine Fisheries Service in 2010 and operates out of the NOAA Beaufort Laboratory. This survey was created to conduct applied fishery-independent sampling and related research focusing on the assessment of spatial variability in distribution and abundance of red snapper and other reef species within the snapper-grouper complex, via data collected from fish traps, video cameras, and acoustics. During this survey, chevron trap catches and associated underwater video recordings were collected from hardbottom habitats from Cape Hatteras, North Carolina, to Daytona Beach, Florida. A total of 494 stations were sampled with camera-trap arrays over 28 sea days between 17 and 114 m depths.

Cruise PC-18-04 Objectives

1. Fishery-independent sampling of randomly selected stations from North Carolina to Florida. Baited chevron traps, with two mounted high-definition video cameras, were utilized for (a) hardbottom reef fish community assessments, (b) collection of reef fish for biological samples (i.e., otoliths and gonads), and (c) comparative gear sampling (cameras versus traps).

2. Use video cameras on chevron traps to address trap selectivity issues, locate and describe hardbottom habitats, and provide an additional index of abundance for stock assessments.

3. Map bottom habitats using multibeam sonar to improve survey design and to expand knowledge of hardbottom habitats in the southeast US (leg 1 only).

4. Use a CTD instrument package to collect environmental data (temperature, salinity, dissolved oxygen, turbidity) at camera-trap sampling locations, and XBTs to sample water temperature during multibeam mapping operations.
