There is presented a brief review of research-and-production activities of the Institute of Fishe- ries of the National Academy of Agrarian Sciences of Ukraine for the year 2009. There have been defined priority tasks by the system of scientific provision and individual measurers directed at effective development of fisheries activities in inland water bodies in Ukraine.
The results of Institute of fisheries NAASU international scientific and technical cooperation on the problems of water bioresources and aquaculture are considered. Priority tasks, above the decision of which scientists in 2009 worked, their achievements and problems, are definite.
In the article the work of the Academic Senate IF NAASU is expounded, and also data on the scientific personnel training of Institute, pedagogical activity of research workers, the subject of scientific researches.
In the article the results of the scientific personnel training of higher qualification for 15 years of Institute of fisheries specialized scientific advice existence are considered, 50 thesis from prior- ity directions “fish-farming” and “ichthyology” are defended.
The article analyses biological state of spawning stock and conditions and efficiency of spaw- ning blue bream in the Kremenchuk reservoir during 2005–2007. There has been anayised effect of water-level and temperature regimes on reproduction of this specie. It was found that temperature of blue bream spawning start diminished by several degrees during last time.
There vahe been examined qualitative indicators, which characterized feeding particularities of perch of the Dniester reservoir — gut content composition and occurrence frequency of food objects. It was found the presence of cannibalism as an adaptative reaction on living conditions. There have been conducted a comparative analysis of feeding spectrum of perch in interseasonal and interannual aspects.
There has been considered special quantity and biomass plancton and zoobentos organisms at the ponds, they biological and food value for carps organism. It is shown necessity increase them quantity and biomass at the fishery ponds.
In the article light up the results of four-year-old researches of ecological system of ponds of agricultural enterprise “Branch “Antonov-Agro” ANTK of the name of O.K. Antonov at their complex fishcultural use in the not-drain mode. A production effect is shown from realization of suggestions of scientists on optimization of landing of fish in the ponds, fight against litter fish and fertilizer of ponds.
The data about pelagic zooplankton occurrence, its size and distribution in the middle part of the Oleksandrivsk’s reservoir in 2006 and 2008 is presented.
Maintenance of heavy metals is investigational in organs and fabrics of river shrines. Distribu- ting of heavy metals in the organisms of river shrines is characterized heterogeneity and depends on organs, fabrics and places of their dwelling.
The paper considers the diversity of algae in the river Irshava as autotrophic component, for- ming the energetic basis of forage resources for invertebrates and fish. The river has been divided into districts according to algal communities diversity.
Researches of variability of morphological attributes and attempt to reveal genetically deter- mined connections between a morphotype and attributes of viability of carps Teleneshtskiys are carried out at their selection for increasing resistance to infectious diseases. Correlated with vi- ability there were the most important selection morphological attributes which can be “signals”. The target standard of selection of selection-valuable genotypes is designed.
In the article are expounded the basic technological receptions of market grass carp growing by more compact density 1500–2000 ind./hа, allowing to multiply fish productivity of market grass carp till 442–1027 kg/ha due to feeding by the ground and water vegetation without feeding of carp by combined feed. The output of general fish productivity by the three-year growing made on ponds 3425–3995 kg/ha.
The material of three plant lines of the new Scaleless Subbreed Type of the Ukrainian Frame Breed of common carp has been investigated for mitochondrial variability. It is established, that genetic markers which have been used in investigations, can be effectively applied for detection of the hybrids in case of intraspecific hybridization or significant genetic divergences.
The were analysis of genetic structure of framed carp populations of Lyubin’ intrabreeding type, breeders forms of framed carp, of scaled and framed carps of Nesvickiy zonal type, and their hybrids Amur sazan with a carp by 4 genetic-biochemical systems of blood. The were found specific particularities of genetic structure by studied loci.
The results of researches of application influence on fish productivity in composition the mixed foods of moist tanning-scrapings preparation (TSP) by ongrowing of carp larvae are resulted. The com- parative food value of zooplankton and mixed foods with 10 and 20% maintenance TSP is given.
Studied particularities of gistological structures of branchial device Acipenser ruthenus, Anguilla anguilla and Salmo trutta labrax. Got given is offered use as material for study of the variety adaptive devil respiratory fish system.
In article the question concerning the properties of bacteria of species Aeromonas allocated from a carp depending of abiotic factors of a natural environment, in particular from temperature is considered.
There are presented data on economical advantages of using American paddlefish in poly- culture of fish farms of Ukraine. As a result of introduction of paddlefish in traditional cyprinid polyculture, the profitability of pond fish farming can rise by more than 2–3 times while achieving economic efficiency of the production by more than 70%.
