tionships between day and night catches in a fishery 

 independent assessment program can increase sam- 

 pling frequency and decrease the cost of sampling 

 by reducing processing time, manpower require- 

 ments, and variability caused by subsampling large 

 catches. Samples from the small trawl could be pro- 

 cessed in approximately 25% of the time required 

 for sample processing from the large trawl. The 

 small trawl required no subsampling. Management 

 agencies should consider these findings when plan- 

 ning long-term programs. 



Acknowledgments 



We would like to express our appreciation to each 

 member of the Gulf Research Program who so 

 conscientiously collected scheduled samples. Thanks 

 are extended to the Texas Parks and Wildlife 

 Department review committee and an unknown 

 reviewer for their valuable comments. Nancy 

 Ziegler prepared the manuscript. This study was 

 conducted with partial funding from the U.S. 

 Department of Commerce; National Oceanic and At- 

 mospheric Administration, National Marine Fish- 

 eries Service, under P.L. 88-309 (Project 2-385- 

 R).
