چکیده
Population-ecological analysis of Aral roach ( Rutilus rutilus aralensis ) was conducted in Tuzkan lake Aydar-Arnasay system Uzbekistan. In the system, it analyzed age structure, body weight, 19 morphometric and 5 meristematic indicators 158 fish specimens caught Lake January February 2020. The main selected as a result statistical are: arithmetic mean; error rate; variability morpho-physiological signs; variable asymmetry meristem indicators. Statistical evaluation to determine reliability survey results. Some features state studied population were identified, which explained by natural-climatic features, well anthropogenic impact on water basin.

Factors affecting between-lake variation in the occurrence of epidermal papillomatosis in roach, Rutilus rutilus (L.).
The theory of island biogeography predicts that the probability of a species occupying an island depends on a dynamic equilibrium between extinction and colonization. Epidermal papillomatosis is a disease manifesting as skin tumours on fish. We studied the factors affecting the occurrence of the disease in roach, Rutilus rutilus (L.), in 34 lakes. The results of discrimination analysis suggest ...

Females and eggs of Toxorhynchites r. rutilus were labeled with 32P by feeding fourth-stage larvae 32P labeled Aedes aegypti larvae. Eggs from females up to 3 weeks in age had detectable levels of radioactivity and individual eggs contained ca. 0.3% of the mother's total radioactivity.

متن کاملReciprocal interactions between roach, Rutilus rutilus, and zooplankton in a small lake: Prey dynamics and fish growth and recruitment’
Recruitment success of roach varied dramatically between 1979 and 1982 in Alderfen Broad, a small lake in eastern England. When fry were abundant (in 1979 and 198 1, but not in 1980 or 1982) the summer zooplankton became sparse and was dominated by copepods and rotifers. In years of good recruitment, as each of the preferred cladoceran prey species entered the diet of underyearling roach, its d...
