Název v původním jazyce

Effects of egg bath and daily removal of dead eggs on the hatching success and production of stage 2 juveniles during artificial incubation in noble crayfish (Astacus astacus L.)

Popis výsledku v původním jazyce

The effects of egg bath (iodine-detergent preparation) and daily removal of dead eggs on hatching success and production of juveniles in stage 2 were investigated during a short (sixteen days) artificial incubation (AI) of noble crayfish eggs. At the beginning of AI, eggs were in phase XII (pulsating heart appearance) and were incubated in 18 polyethylene 1 liter jars (100 eggs/jar, egg density 4.5 eggs.cm(-2)). Six different treatments were tested during AI: C: control group without removal of dead eggs and egg bath; R: daily removal of dead eggs without egg bath; R-LB: daily removal of dead eggs, low frequency of egg bath (once every five days); R-FB: daily removal of dead eggs, frequent egg bath (once every three days); LB: without removal of dead eggs, with low frequency of egg bath; FB: without removal of dead eggs, with frequent egg bath. Egg bath was performed by iodine-detergent preparation Jodisol (dose 2 ml.l(-1) and exposition time 2 minutes). Results showed a better hatchin
