Deep spawning of perch (Perca fluviatilis, L.) in the newly created ChabaA (TM) ovice Lake, Czech Republic

The egg strands of perch were found at up to a depth of 20.2 m and, on average, 88% of perch spawning activity occurred at depths greater than 3 m....

The influence of the trawl mouth opening size and net colour on catch efficiency during sampling of early fish stages

The efficiency of different sized (0.5 m × 2 m, 1 m × 2 m, 2 m × 2 m, 4 m × 2 m) and coloured (black, white) ichthyoplankton trawl nets and the...
