Possible effects of climate warming on the timing of spawning, juvenile abundance and catches of pikeperch, Stizostedion lucioperca (L.)

The effects of climate warming on the population dynamics and exploitation of pikeperch (Stizostedion lucioperca (L.)) were studied in the Baltic Sea and its drainage area. In southern (61°N) and in central Finland (64°N) the average spawning period will be about one month earlier due to climate warming in the year 2050. In Pärnu Bay, Estonia (58°N, 24°E), the juvenile abundance of 0+ pikeperch will be higher, and higher abundances and warmer waters will also enhance fishermens catches.
