Efficiencies of two types of seine net for 0+ fish sampling

Young of the year (YOY) fish assemblages are used as indicators of a river ecological state. Though, some aspects of YOY fish sampling methodics are still not definitely solved. Present study compared YOY sampling efficiency of 5 m beach seine net and 10 m beach seine net. Study took place in a regulated upstream weir stretch of Morava River near the Lanžhot town (83. r. km) in September 2002. Ten localities were sampled by both types of net. Simultaneously, comparative electrofishing survey was conducted in the same river stretch
