Comparison of trap and baited stick catch efficiency for noble crayfish (Astacus astacus L.) in course of the growing season.

Popis výsledku v původním jazyce

Noble crayfish (Astacus astacus) were caught using traps and baited sticks in Světlohorská reservoir, and the catch efficiency and size and sex composition in catches were compared during the growing season (May - September). One trapping period per month (1.5 hour from 6-7:30 pm) was applied. The highest number of crayfish was caught by traps and baited sticks in September, while the lowest number were caught by traps in July and August and by baited sticks in July. The greatest CPUE of traps and baited sticks was recorded in September. The least CPUE of traps and baited sticks was recorded in July. Baited sticks were found to be more effective than traps except in July. Males dominated in all catches, with the exception of trap catches in September.Females were totally absent in traps in June, July and August. Baited sticks caught females more successfully than traps, especially females with eggs. Traps did not catch any females with eggs. Males and females caught by baited sticks w
