7.0 Scientific 2-metre Beam Trawl Results 7.1 Fish Catch Rates and Species Distribution The total number of individuals caught and the catch rate (number of individuals caught per hour) by fish species and sampling area are given in Table 0.17 and illustrated overleaf in Figure 0.31. The catch rates for fish species by sampling station are given in Figure 0.32.


A total of 28 species of fish were caught in the scientific beam trawl survey; 20 within East Anglia THREE, and 27 along the export cable. B. luteum was the most abundant species along the export cable whereas (P. minutus) was more abundant within East Anglia THREE, followed by E. vipera and (A. laterna). All other species were caught in relatively low numbers.


Station T12 within East Anglia THREE yielded the highest catch rate (1,222.6/hr), with B. luteum and P. minutus representing the majority of the catch (43.7% and 42.9% respectively).


The total catch rate within East Anglia THREE (785.5/hr) was approximately double that recorded along the export cable (358.8/hr).
