Effect of cyanobacterial blooms on the abundance of the flounder Platichthys flesus (L.) in the Gulf of Finland

Year: 2007

Type: article

Abstract: An extensive cyanobacterial bloom in the southern Gulf of Finland was observed from the end of June to the middle of July 2002 with a subsequent decaying phase of algae during 2–3 weeks after the bloom collapse. Aphanizomenon was thepredominating genus in offshore areas, reaching in abundance the absolute maximum of the period 1997–2004. Mainly dead mass of phytoplankton driven to the coastal waters by wind affected significantly the abundance of 1-year-old flounder. Catch per unit effort of commercial size flounder decreased at several national fishing rectangles that were exposed to strongest cyanobacterial blooms according to satellite images. Strong cyanobacterial blooms were followed by a decrease in the abundance indices of the flounder spawning stock in Estonian waters of the Gulf of Finland.
