Assessment of the bycatch level for the Black Sea harbour porpoise in the light of new data on population abundance
Study Type
Field study in the wild
Location
Black Sea
Target catch
turbot (Scophthalmus spp)
Effect on bycatch species
Bycatch rates showed seasonal variation with marked increase in summer, compared to spring. Total annual bycatch of harbour seals in Black Sea estimated to be between 11,826 and 16 200 individuals.

Looming-eyes buoys fail to reduce seabird bycatch in the Icelandic lumpfish fishery: depth-based fishing restrictions are an alternative
Study Type
Field study in the wild
Location
Húnaflói Bay, northern Iceland
Target catch
Icelandic lumpfish
Effect on bycatch species
no effect
Effect on target catch
No effect, but a strong correlation between bycatch rates and net depth was observed, suggesting that fishing below 50m only would highly reduce seabird bycatch
