Ortiz et al : Estimates of bycatch from tfie shrimp trawl fishery in the Gulf of Mexico 



599 



to the same age class, usually the age-0 class. This may 

 not be true for some species. Thus, bycatch estimates 

 should take into account number of fish per age or size 

 class.

This research was supported by a grant provided by 

 MARFIN (NA57FF283-01); additional grants came from 

 the Florida Sea Grant College Project (R/LR-8-371. We 

 thank Victor Restrepo from the University of Miami 

 RSMAS for his scientific advice, Scott Nichols from the Pas- 

 cagoula laboratory of the NMFS for providing the bycatch 

 database and algorithms, and Nancy Cummings from the 

 NMFS Miami laboratory for her comments and sugges- 

 tions. Three anonymous reviewers provided valuable com- 

 ments on the final draft.
