TABLE 7. Matrix of Spearman's rank-order correlations for various Southern New England winter flounder 

 abundance indices from 1964 through 1987. 



National Marine Fisheries Service 'Red Book' commercial landings annual CPUE for Rhode Island 

 (lbs/50-ton unit). 



National Marine Fisheries Service annual CPUE for statistical area 539 (lbs/directed trip). 



Connecticut DEP-licensed commercial trawler CPUE (Ibs/lrawl-hr). 



University of Rhode Island annual 8-mean trawl CPUE (advanced 1 year for comparisons). 



NU trawl monitoring program annual 5-mean trawl CPUE for all winter flounder. 



Niantic River winter flounder survey median trawl CPUE for adult (> 15 cm) winter flounder. 



Shown for each Spearman rank-order correlation: 



correlation coefficient 



probability level, where NS - not significant, * - significant at p<0.05, ** - significant at p<0.01 



number of observations 



1 year. Similarly, the annual 5-means for the 

 trawl monitoring program were significantly cor- 

 related with the three Rhode Island indices. Since 



larger fish made up one-half to three-quaiters of 

 the catch in the Millstone trawl survey, no lags 

 were used for the comparisons.
