Comparison of abundance rankings with 

 other surveys 



The abundance rankings of the dominant taxa esti- 

 mated showed some similarities among the three sur- 

 veys (Table 5). The six most abundant taxa in the 

 bottom trawl surveys were represented in the 10 most 

 abundant taxa in both ichthyoplankton surveys, but 

 the coherence was stronger (top three species the 

 same) for the July Methot trawl survey than for the 



May bongo-net survey. The seventh most abundant 

 species in the trawl survey, Errex zachirus, was 

 ranked 14th in the Methot trawl collections but did 

 not appear in the bongo-net sampling. A comparison 

 of the ranks of only the taxa that were mutually 

 present in samples from each gear type showed that 

 the trawl survey was more similar in ranking to the 

 Methot trawl survey data (Spearman Rank Correla- 

 tion, r - 0.50) than to the bongo-net survey data 

 (r = 0.23).
