Comments: | Spawning sites were mapped using artificial spawning nests built in the lake in order to determine the timing of spawning of pikeperch and locate the spawning areas to manage dredging activities around the lake. Additionaly, this study aimed to find the most frequently used spawning depths as well as temperature conditions at the onset and mode date of pikeperch spawning. |
