dc.description.abstract | The brooders of kutum fishes, bream and pike-perch are caught in their spawning grounds, at the commence of spring season in west and eastem parts of Gilan. After eggs stripping and larva-culture until fingerlings size in hatchery, the seedling fishes are released through their natal rivers for down stream migration into Caspian Sea In the mentioned year 127.2* 10 Rutilushisii kutum fingerlings with the average weight of I .29 g and length of 4.8 Cm are produced. Considering the mean weight of fingerlings released in Gilants rivers, nearly 16 % fingerlings were under I grand weight group of 1-1.5 g comprised 68 % , Transportation procedures of fingerlings releasing lasted 5 months and further than 79% of fingerlings released in june-Agust (Peak of warm weather), this coincide with reduced water discharge and low depth in rivers . These ecological extremity needs to be carefully checked by assessment recruitment of stocked fingerlings into fishery.
