Аннотация: Generally, demersal fisheries in the North basin enjoy satisfactory commercial conditions. They correspond basically to the advanced country level and provide prerequisites to the fishing industry modernization and increase in its competitiveness in the global market. Application of some efforts to advancing the state management mechanism, improvement of efficiency in our struggle against illegal fisheries, regulation of domestic fish market, development of policy to promote the national fishing industry at the international level, etc. would provide conditions for achievement of significant progress in exploitation of the North basin demersal fish species in the nearest future.

Аннотация: A model of population and fisheries dynamics for the Northeast Arctic cod (Gadus morhua morhua) in the Barents Sea was developed. The model based assessments include: maximum sustainable yield (655,000 t) and corresponding fisheries mortality level (F) (0.48); maximum mean annual profit of cod fisheries (13.7 bln RUR) with F = 0.23; fisheries mortality level correspoding to maximum employment in fisheries F = 0.85. The existing cod exploitation level based on 0.4 target mortality level promotes for achieving the objectives to maximize catch and profit.

Аннотация: The setae of the mouthparts of juveniles and adults of the giant freshwater prawn Macrobrachium rosenbergii and the australian red claw crayfish Cherax quadricarinatus was examined. Prawn M. rosenbergii and crayfish C. quadricarinatus are important objects of world freshwater aquaculture. Main types of setae and its distribution on the mouthparts were determined. The interpretation of setae with relation to intensity and direction of mechanical impacts is given. The structures on the setae surface vary in dependence of mechanical load intensity. The following sequence of structures types as long thin setulas, short setulas, denticles, the absence of external elements combined with thick shorten setaes, have direct correlation with intensity of the mechanical impact. The presence of denticles and ordering short setulas indicates that only one side of setae is under the mechanical action. The fact of impact of significant body size transformation during ontogenesis on the setae distribution on the mouthparts was established. The tendency of length reduction and/or disappearance of setulas and denticles was observed. Lenth of setae decreases against the body size. The increase of number of setae takes place and tight grouping of main types of setae occurs. An assumption made that with increase of body size the efficiency of separate setulas decreases and, for adult individual, groups of setae should be considered as functional units.
