Feasibility of removal of dioxin and dioxin-like PCB's by intensive fishery of herring and sprat in the Baltic Sea

image of Feasibility of removal of dioxin and dioxin-like PCB's by intensive fishery of herring and sprat in the Baltic Sea

In this report it is discussed and assessed whether it is feasible to reduce dioxin content of herring and sprat in the Baltic Sea by a period of intensified fishery in the region and if intensified fishery causes adverse environmental effects or affects the stocks of other species like cod, salmon and other pelagic species. The background is the present problems complying with the European Commission limit values for dioxins and dioxin-like PCBs in Fish from the Baltic Sea. Also flame retardants and other hazardous substances present an increasing quality problem for the fisheries sector.

Potential effects of intensive fishery on other fish stocks, seals and the ecosystem in general

Herring and sprat are zooplanktivorous fish species which occupy an intermediate level in the trophic food web of the Baltic Sea. An intensive fishery for these species could potentially have impacts on other food web components and the ecosystem in general. In this section, we identify some of the impacts that a targeted fishery on herring and sprat could have for these components.
