Fishery use of herbivorous fish species commercial populations in the waters of the volga-caspian and north caspian fisheries subareas
The intensive forming of exploited population of herbivorous fishes, such as grass carp, silver carp and spotted silver carp in low water periods (2006, 2009-2012, 2014, 2015) in deltaic water reservoirs of the Volga River and internal watercourses of its flood-lands (such as Akhtuba, Kharabalyk, Enotaevka, Khurdun, Buzan, Vladimirovka, Gerasimovka, Borisovka, Vinokurovka, etc.) is shown. Such forming happens in the Volga- Caspian and Northern-Caspian fishery sub regions, especially in spring-summer fishing season. The work gives potentialities of theirs’ productiveness in the natural habitat and fishing harvesting.
