Özet:

 

The effect of pheromonal stimulation on the progress of maturation in wild Eurasian perch, Perca fluviatilis, females was determined. The females were kept in two separate tanks in a flow through system (12°C). Into one of the tanks (experimental group) males were placed together with females. A second tank was without males. The maturation stage of females was determined in vivo every 10 days up to day 30. The results obtained indicated that pheromonal stimulation induced uneven maturation and significant diversification of maturation stages (from I to V) in females that were kept with males. In females kept without males 90% of fish were still in stage I. The results suggest that spawners of both sexes should be kept together if it is necessary to stimulate reproduction, whereas they should be kept separately in order to synchronize or delay the spawning. 	 	 		 .
