About problems on prognosis background on some inner water bodies of Western Siberia
The authors state the crisis in the field of prognosis background for inner water bodies. They discuss the problem on the example of the Lower Ob basin (Tomsk region) where the possibilities for primary data collection have been worsening in the last years for some valuable fishes (sterlet, inconnu, muksun). To restore normal work on prognosis background, fishermen, in the authors' opinion, should be obliged to facilitate scientists in researches and give statistical data on catches. In case of refusal, the license on fishing should be withdrawn. Besides, it is necessary to organize control fishing (for sterlet) or hand the function of TAC allocation to Gosrybcenter (for inconnu and muksun) which would collect the material on populations of semi-anadromous fishes. Assets from scientific quota realization may be transferred to accounts only on the assumption that prognosis researches would be financed sufficiently.
