of the species tested (Table 2). The combined regres- 

 sions had significant positive correlations (0.51-0.89) 

 explaining 26-79% of the variation. 



Catch per tow in the two trawls was positively cor- 

 related. Correlation coefficients (0.48-0.93) were 



significant for all species meeting the criteria for 

 analysis (Table 3). The percent of variation explained 

 (r 2 ) varied from 23 to 86%. 



There were no significant differences in the day- 

 night catch vs. catch relationships for total organ-
