The present paper describes the results of induction spermiation and ovulation of ide (Leuciscus idus L.) during and out of spawning season using CPE with addition of hCG, hCG and ovopel - GnRH containing pellets. Males from control group produced significantly smaller volume of milt (season) than those from hormonally treated groups. Significant differences in spermatozoa motility was noted between treated and control males. The percent of ovulated females from groups treated with CPE and ovopel was 100%. Fish from control groups and treated with hCG did not ovulate. The total spawners mortality was quite high, especially in fish treated with ovopel. Generally, all recorded parameters in out of spawning season were lower than those obtained during artificial propagation in natural spawning time.
Key words: ide, artificial propagation, hormonal treatment, spawners mortality..
