The article is devoted to the study of biological characteristics of the north Caspian roach of the Daghestan coast of the Caspian Sea. Discussed are size and weight, fatness, passing the stage of gonad maturity, the absolute individual fecundity and feeding habits. The degree of occurrence of organisms in the food lumps with identification of dominant groups is determined.

River Fish

The offshore zone of the western coast of the Caspian Sea is one of the most highly productive. Of the 63 species of fish that live in the Caspian Sea, 34 species are found on the Krainovsky coast, 42 % of which are carp. The most numerous is the roach Rutilus rutilus caspicus (Jakowlev, 1870), which makes up 50–86 % of the number of semi-passerine and river fish. The article presents the results of studies of the peculiarities of the biology of the roach Rutilus rutilus caspicus of the Krainovsky coast of the Caspian Sea. The roach is noted in the catches constantly. Her age in the networks ranges from 2 to 10 years. The share of 3-5-year-olds accounts for 81 %. Females in catches make up 66 %, males - 34 %. The parameters of the Bertalanfi equation are characterized by the following values: L =38.8 cm, K = 0.12, t° = -2.67. The fecundity of the roach on average is 30.2 thousand eggs and tends to increase with increasing length and weight of the fish. As the roach grows, the composition of its food changes significantly. The maximum fed roach length from 10 to 20 cm.

The work presents microstructural analysis of the oocytes of the common carp and the caspian roach that are on the stages of the protoplasmic and trophoplasmic (large) growth of the germ cells. Seasonal changes of quantitative and qualitative transformations of structural components of oocytes are also given. It is shown that from the early spring to the late autumn in the ovaries of the caspian roach and the common carp found are the oocytes of different generations, which are both at the generative and vegetative stages of growth of germ cells and along with this can occur, with varying intensity, resorption of whole oocytes and their individual structures. It has been established that spawning is common in the common carp, generative and regenerative processes occur simultaneously, while in the wobble spawning is simultaneous, the generative processes begin only after the regeneration of the sexual gland.

The article presents the results of studies of feeding characteristics of such cyprinid fish species as the roach Rutilus rutilus caspius (Jakowlev, 1870) and the bream Abramis brama (Linnaeus, 1758) in various parts of the Daghestan coast of the Caspian Sea. The material was sampled along the entire Daghestan coast of the Caspian Sea, from the Kizlyar Bay to the mouth of the Samur river, in different biological seasons in the period of 2017–2018.

Genetic Pools

Genetic analysis using restriction fragment length polymorphisms (RFLPs) of cytochrome b in mtDNA was made to clarify genetic variations among two Iranian Rutilus rutilus caspicus populations of commercial importance from the southern coast of the Caspian Sea. Polymorphism was detected using six restriction enzymes and a total of six composite haplotypes were identified. Four haplotypes were rare occurring only once in two regions (west and east of the southern Caspian Sea). Nucleotide and haplotype diversities were higher in the south-west region of the Caspian Sea (π=3.43%, h=23.3).The nucleotide divergence between the two populations was low (0.064%). The test for heterogeneity of composite haplotype frequencies gave no significant outcome for all samples (χ2=0.137, P≤0.05). The results indicate that significant attention should be paid to the genetic characterization of R. rutilus caspicus populations for conservation of their genetic pools and aquaculture policies at the coastlines of the Caspian Sea.
