Review of the Trans-border management plan for European eel, Anguilla anguilla, in the Polish-Russian zone of the Pregola River basin and Vistula Lagoon

This is a review of the Trans-border management plan for European eel, Anguilla anguilla, in the Polish-Russian zone of the Pregola River basin and Vistula Lagoon (2014) (TEMPP).

The Eel Management Unit (EMU) consists of the Pregola, Banówka and Świeża river systems that drain into the Russian part of the Vistula Lagoon, and the lagoon itself. The surface area of this brackish water lagoon is about 838 km2, with about 510 km2 in Russia and 328 km2 in Poland. Neither the total drainage nor the total wetted area of inland waters are provided. The rivers and lakes in Poland all drain through the Rus-sian zone.

The state of eel populations in inland waters of Poland is described in terms of the length, weight, sex ratio, condition factor, age, length at age and annual growth rates, of feeding or not-feeding (equivalent to yellow and silver) in eels caught by commercial fisheries and scientific surveys of select lakes. No information was presented for Rus-sian waters. The state of eel populations in the Vistula lagoon (Poland and Russia) is described in terms of length frequency, age structure, silvering index of commercial catches.
