Abstract: Within the project “Services for monitoring the conservation status of fish species from Romania” scientific fishing was conducted in a total of 21 stations on the Bistrita and Moldova rivers, on theirs upstream sectors and tributaries. Have been identified 16 fish species with a total of 537 individuals. All specimens were measured and weighed. The most common species were bleak, minnow, chub and trout.
