There is presented analysis of systemic approaches in planning and organization of scientific provision and industrial measures directed at development of paddlefish aquaculture in Ukraine. Priority trends of paddlefish introduction into aquaculture are defined. There are presented calculated data on necessary quantity of brood fish, scope of artificial reproduction and possible production of commodity paddlefish in freshwater aquaculture of Ukraine.
Among of consumer descriptions of carp a smell occupies one of ponderable places. He has the biological, biochemical, physical, domestic and agricultural origin. The sources of fish smells forming in liquid ponds, facilities of their origin, liquidation and prevention are considered.
There has been analyzed current quantitative and qualitative composition of fish juveniles on different spawning sites of the Kremechuk reservoir. We performed an analysis of fish juveniles distribution at different years of the reservoir existence. It was found that major places of the largest concentration are located in upper and lower sections of the reservoir.
The article examines the efficiency of using some fishing gears for catching fish in rivers of Transcarpathian region on the example of rivers Teresva and Irshava. It is proposed to adopt a standard method for fishing sampling in mountain rivers of Ukraine.
The structural characteristic (taxonomic structure, biodiversity, abundance and biomass para- meters, production of the dominant groups) of macrobenthos communites of the Sasyk reservoir were investigated. The parameters of fish capacity were calculated on base obtained results. Also data of the bioindication analysis of water quality are presented.
Character of influence of mineral nitrogen compounds on survival of embryos, larvae and uneven-age groups of a carp and a grass carp is investigated. It is marked, that the basic negative effect has ammonium in its molecular and ionic form, nitrites evince considerably smaller toxicity and are hemotoxic poison, and nitrates do not influence on fishes. It fixed, that on a measure of passing of an ontogenesis tolerance of fishes to action of ammonium nitrogen strengthens. Change of norms of reactions to action of toxic factors of environment essentially depends on a degree of development of organs and systems of respiration, a circulation of the blood and an excretion. An apparent role plays gradual and long adaptation of fishes to influence of toxins.
Influence allochthonous nitrogen on the contents of the total protein, lipids and glycogen in organs of a carp is investigated. It is marked, that the balance between synthesis and utilization high-energy compounds depends on temperature of water, force of action of toxic loading and efficiency of functioning adaptable and compensatory mechanisms in an organism.
Ranging of water quality of stations of Dnieprovske reservoir has been conducted on the basis of zoobenthos indexes, summarized by the combined index of the state of community. Estimation of the degree of inhibiting influence of sewages of different origin has been carried out concer- ning zoobenthos organisms and areas of the water-body part which is influenced by sewage. It has been found out that the cleanest areas of the reservoir are situated in the profundal and in influxes which are not undergone sewage action.
Species composition state of ichthyocenosis are determined and recommend-dations are de- veloped concerning the preservation of species diversity and conditions for natural reproduction for аborigine ichthyofauna of Styr, Horin, Ikva, Slych rivers.
It was shown that the introduction of the composition of fish feed holozernoho oats in a com- plex with rostostymulyuyuchymy additives and enzymes promotes weight of commodity fish the fishproduktyvity of the ponds and reduces feed costs and the cost of рroducts grown.
There are given the results of zooplankton research when feed the one-year carps by mixture of mixed fodder with adding distillery dreg (20%). It is revealed the influence of distillery dreg on zooplankton development.
It were analized the world problems of utilization of alcogol production waste material and the possibility of its effective using in the in a fish-farming. It was described our view on dreg as forrage additive and organic fertilizer in aqriculture.
There have been given an analysis of work efficiency of enterprises of the association “Ukrrybgosp” and efficiency assessment of economic-organizing mechanism of the JSC “Lviv fish combine” management.
