Survey 
Figure: Results from the stable isotope analysis. Mean 5”N differed significantly between cod from 
stations sampled in the German Bight (GB) with 15.37 %o (4 1.49) and cod sampled in the Offshore 
Wind Farm (OWF) during summer (OWF summer) with 19.36 %o (4 0.10; p < 0.05) and with 18.64 %o 
(+4 0.78; p < 0.05) during winter (OWF winter). Mean 5*C also differed significantly. Cod samples from 
the German Bight had with 18.67 %o (+ 0.59) a significantly lower mean $*C ratio than cod with — 
17.27 %o (+4 1.02; p < 0.05) from the OWF area during summer or with -17.18 %o (+ 0.65; p < 0.05) 
during winter (Table 1 and Figure 5).
