“…In 2019 this figure was 53793 individuals. Despite the fact that anthropogenic factors [1,2], climatic factors [3][4][5], and the influence of predators [6] contribute to changes in the number of animals living in the wild fauna, abnormalities associated with the loss of reproductive qualities play a special role. Deviations in the organs of the genitals in males can lead to a violation of full-fledged fertilization of the female.…”

In the wild fauna of the Amur region there has been a decrease in the population of Siberian roe deer in recent years. Abnormalities associated with loss of reproductive quality affect the number of animals. When analyzing pathological abnormalities in the reproductive organs, it is important to take into account not only the morphology in the structure of the genitals, but also the defective development of spermatozoa. The aim of this research is to study the influence of morphological deviations in the testes and epididymides in male Siberian roe deer on the development of spermatozoa.The object of the study was 24 males of Siberian roe deer aged from 1 to 6 years old; they were divided into 2 groups of 12 individuals each, from which the testes with epididymides were selected, and visual morphometric and histological studies were performed using generally accepted methods. Morphological abnormalities in roe deer were observed at the age of up to 1 year old. The greatest number of pathologies was found in male roe deer aged from 2 to 3 years old and older than 6 years old. Histological analysis of the testes and epididymides showed violations in the composition of the structural elements of this organ; they contribute to the further development of deviations. The main reason for the violation of spermatogenesis in roe deer is oligospermia, deformation of the convoluted seminal tubules, which leads to a violation of the development of gonadocytes.

Production of ecological wild meat products in the hunting organizations of the Hokkaido island (Japan) and the Amur region (Russia)

With the growth of the population of our planet, the problem of food production is increasing. In this situation, the importance of hunting farms in providing people with environmentally friendly meat products is increasing. During the study period, about 380 elk, 350 red deer, 2800 roe deer, 240 reindeer, 400 musk deer and 125 bears were harvested annually in Amur region. In Japan, game meat products are obtained mainly from sika deer, wild boar and brown bear. Meat products are used in food by hunters, sold to restaurants within the country and exported. As a result of our research, we came to the following conclusions: the game products in Amur region are mainly used by the hunters themselves in their private consumption, and only a small part of them goes for sale in food stores and agricultural markets. Even smaller amounts of wild meat products go to restaurants. Hunting is unpopular in Japan, and young people in general are not ready to engage in it. In our opinion, "wild meat" is an attractive environmentally friendly product for people in Russia and Japan and can undoubtedly serve to attract tourists to places of recreation and into gastronomic tours in Japan and Russia.
