1 SEAMAP-SA (Southeast Area Monitoring and Assessment Program) (South Atlantic) Shallow Water Trawl Survey

2 SEAMAP Stations

3 Types of Data Annual / Seasonal/ Regional Species occurrence Species abundance Biomass Life History Age-growth Maturity Hydrographic Data Salinity Temperature Wave height.

4 Seasons Sampled Spring: April – May Summer: July – August Fall: October - November

5 Year Strata 51 Strata 53 1990-2000 8 4 2001 4 4 2002-2003 4 3 2004 4 4 Number of Trawl Samples/Season in Myrtle Beach Area

6 Catch from a 20 minute tow..

7 Most biological data is entered directly into a database as animals are counted or measured.

8 High Priority Decapod Crustaceans White Shrimp Brown Shrimp Pink ShrimpBlue Crab

9 High Priority Finfish Structure Surface Mid/Bottom Bottom

10 Marine Turtles Four species of marine turtle are encountered All data is reported to federal & state monitoring agencies LoggerheadLeatherback RidleyGreen (not pictured).

11 Age-Growth / Reproduction Otoliths are removed in the field and returned to the lab for processing Gonad tissue is removed in the field Age is determined from an otolith cross section Microscopic evaluation in the lab verifies field maturity assessment
