Abstract
The main cause of different quality of fish consists in changes in fish habitats including food supply. Variations in morphological quality of fish as well as in the age, size and sex composition show the population dynamics.
Our knowledge of the main causes and regularities of commercial fish stock variability allows more substantiated approach to the assessment of parameters of fishing regulation and forecast.

Abstract
The article presents the results of calculations of the emission of dioxins in ambient air from stationary sources, transport and combustion processes on the territory of the Chechen Republic in different periods of industrial development. The main sources are the processes of uncontrolled burning of solid waste, fires and transport.

Abstract
Comparative analysis of lipid parameters, lipid peroxidation processes and antioxidant system in liver and muscles of five-yearold sterlet raised at the sturgeon fish-breeding farm and from the wild population has not revealed any deviations from the physiological norm of the fish. Some minor differences in the parameters studied reflect, possibly, compensatory reactions of the organism to the specific conditions of breeding.

Abstract
As a result of acclimatization of Black Sea mullets of the kind of liza (L.auratus and L.saliens) ichtio industrial herds have been formed. At the same time the nature of migration and adaptive features have changed. Grey mullet sexual puberty in the Caspian Sea happens at the age of 3 or 4. The length and the rate of growth increases. The weight of the Caspian-sea grey mullet is bigger than that of the Black-sea grey mullet.

Abstract
Anoplotsefalyats (Moniezia expansa, M. benedeni, M.autumnalia, Avitellina centripunctata, Thyzaniezia giardi) are common in farm ruminants of Azerbaijan. There are no strict zoning in their distribution and no specificity for the hosts. It was established that in Azerbaijan there are 27 species of oribatid mites that are involved in the life cycle of monieziozis out of which 20 species recorded to be new to our fauna, as their intermediate hosts. Infection of the final (sheep, goats, cattle, buffalo) and intermediate hosts (oribatid mites) happens all the year round. Maximum infection occurs in early spring and late autumn.

Abstract
Revealed food items consumed by forest dormouse (Dryomys nitedula Pallas 1778) individuals in various forests in Daghestan; 18 in an oak forest and 19 in а hornbeam-beech forest. Diversity index of food items in the oak forest was 7.66 and in the hornbeambeech forest was 12.67. The food items diversity index distinction is not formed by quality of food items and caused by larger differences between shares of food items in diet of the species individuals in the oak forests. Seasonal dynamics of the main food types showed reducing of animal food type share from spring to autumn and growing of seed food type share in some period.

Abstract
In the last 15-20 years of the twentieth century in the Volga-Caspian region, the fishing has changed dramatically fishing conditions that have led to considerable changes of the fisheries in this region. Venterny fishing in the region has a high selectivity of fishing gear and the quality of fish caught. To improve fishing Venter is currently at the Department of Industrial Fisheries ASTU developed new designs. This significantly increases the catchability of fish venternymi plants.

Abstract
The study of fish population dynamics at system approach is most appropriate enabling consideration of processes affecting population abundance and structure and investigation of processes of stock composition and abundance regulation, fishery management. At that, it is reasonable to use some notions and ideas of the general theory of systems and cybernetics as an individual within the population and their aggregate represent compound dynamic systems studied by cybernetics.

Abstract
One of the main tasks of fisheries science and practice consists in maintaining commercial fish stocks on the level that ensures their sustainable utilization. Fishing intensity and selectivity are the basis of rational fishery and affect, on the one hand, commercial stock reproduction and, on the other hand, efficiency of stock utilization especially through combining selectivity regulation and fishery intensity. Commercial fish stocks may be maintained on the level close to the optimal one in different ways.
Fishery intensity control based on total allowable catch (TAC) has been widely distributed. According to this term an annual assignment of catch quotas is performed for every fish species and fish group in a certain fishing area in order to avoid the risk of overfishing or underfishing.

Abstract
When young sterlet is suffering from tympanism, biochemical and pathophysiological disorders are observed; the activity of malate dehydrogenase and succinate dehydrogenase lowers in the fish liver and muscles, while the activity of lactate dehydrogenase in-creases. Such disorders are accompanied by changes in the level and balance of ω-3 and ω-6 fatty acids towards decrease in ω-3 fatty acids.

Abstract
At the present time the lake Generalskiy completely went dry, water surface of the lake Maerskiy is a little more than 1 hectare. The bottom of the lake Generalskiy is completely overgrown by woody, shrubby and grassy vegetation. Was formed here biocenosis with their flora and fauna, which is a kind of «island of life» among the surrounding Sands. In the article the systematic list of the vegetation cover are given.

Abstract
In this article we studied the chemical particularities of ground water of the North Daghestan, using by population as drinking water. In particular we examined the problem of arsenic pollution.

Abstract
The impact on marine algae Thalassiosiraweisflogii, Pseudo-nitzshiadelicatissima of copper sulfate, chloride of mercury, methylmercury were studied. Found a sharp increase sensitivity FS 2 of microalgae cultures and natural phytoplankton to salts of heavy metals in the conditions of the light of the stress that is associated with inhibition of protein synthetic reactions. Conclusions are made about the prospects of the use of fluorescence of chlorophyll "a" for biotesting.

Abstract
Eutrophication of water bodies, especially small, has become a ubiquitous problem. In this connection the efforts of the experts is increasingly aimed at the search for the methods of monitoring, prediction and control of this undesirable and dangerous process. One of the methods to assess the level trophic status is based on the determination of the content of chlorophyll-a, which was used in integrated studies of the ecological status, and trophic status of the water bodies of the Coastal plain of Dagestan.
AGROCULTURAL ECOLOGY
103-109 764
Abstract
Pollution of the chernozem typical (mountain) Cr, Cu, Ni and Pb oxides leads to deterioration of its condition: activity of a catalase and dehydrogenase decreases, cellulolytic activity, an abundance of bacteria of the sort Azotobacter, worsen indicators of germination and initial growth of a garden radish. Extent of decrease depends by nature metal and its concentration in the soil. The studied TM oxides form the following row on extent of negative impact on biological properties of the chernozem of typical (mountain): CrO3> CuO> = PbO> = NiO.

Abstract
For the first time polychlorinated dibenzo-para-dioxins, dibenzofurans and toxic biphenyls were found in biological tissues of population in the Chechen Republic. The content in blood was determined within the range of 14.59-61.11 pg TEQ PCDD/F/g lipids and 2.23-48.86 pg TEQ PCB-WHO/g lipids. Dependence on the age of donors was found. The range of values of PCDD/Fs content in breast milk of Chechen women (3.9-14.7 pg/g lipids) corresponds to the data for Russia cities having no active emission sources of chemical production. The levels of PCB-WHO detected in breast milk of women in the Chechen Republic (1.04-3.56 pg/g) are by 5-10 times lower than in Russia at large. This testifies to effect that there have been no active sources of PCB emission for at least 5 recent years.

Abstract
This article describes the modern situation in environmental consciousness and base to assessment of biological diversity from anthropocentrism (the modern economic theory) and theocentrism (religious philosophy) points of view. On the basis of economic theory we derive scheme for calculating the total economic value of biodiversity and then show the limitations of this method and give the basic religious and moral principles to approach the problem.
