8. Thirty (0.1%) observed hauls targeting summer flounder took place between Cape Charles, VA and Oregon Inlet, NC during Jan 15-Mar 15, 1994 and 1995. During this time and area, TEDs were required; however, TEDs would not have been required here under the 1996 regulation which shifted the TED boundary south. Thus, using 1994/1995 data could cause the total bycatch estimates to be biased low in comparison to years with revised TED requirements. The small percentage of data (0.1%) involved, however, would make this bias negligible. Furthermore, the risk of interaction north of Oregon Inlet between Jan 15-Mar 15 is minimal due to cool water temperatures (FR 59:10584 March 7 1994).
12. To check whether this assumption was valid, a second method for estimating the amount of VTR effort using TEDs was calculated. In the second method, VTR vessels were assumed to use TEDs based on regulations for requiring excluders in the trawl fishery for summer flounder (see “The Use of a Turtle Excluder Device” under “Observer Data”). Under this method, approximately 2.7% of VTR effort would use TEDs if there was 100% compliance with the rule. Examination of the observer data revealed that there was not 100% compliance (compliance with the rule was roughly 73%). Therefore, the assumption that 1.9% of VTR effort used TEDs was considered reasonable.
