“…A promising ap-proach would be to obtain fish reproduction in winter and fingerlings raising by April. In this case, it is possible to grow commercial fish for 1 season in open systems [3,4].…”

In December 2022, 10 females and 2 males of common carp (Common carp) from ponds (water temperature 10°C) were placed in RAS pools and 2 females and 2 males (control group) were placed in an open pond in Uzbeki-stan. In January, the water temperature was increased by 1°C in two days in the RAS for two weeks. Since January 20, the water temperature was 22-24°C for two weeks. The fish had weigh 2950 – 3980 (average 3235) g. From February 3th, 4 females and 2 males were injected with the pituitary gland according to the routine methods and ripe eggs and milt were obtained, ripe eggs (920 g) were incubated in Zuger apparatus. Fertility was 90%, Feb-ruary 7th, the beginning of hatching of the larvae was determined. The yield of larvae from eggs was 64%. Injected at the same time, 2 females and 2 males from the control group of carp did not produce ripe eggs and milt at all.

“…River trout, a new object of fisheries in Uzbekistan, is a cold-water fish that can be bred in lowland and mountainous areas. In addition, the conditions in the mountainous and mountainous areas of Uzbekistan are favorable for the cultivation of river trout, which serves the successful development of river trout in Uzbekistan and the creation of a new promising product for the table of the people of Uzbekistan and for export [7,8].…”

Trout fishing means raising fish in water whose temperature does not exceed +18°C under completely or partially artificial conditions. Today, several fish belonging to the salmon family are bred in cold water fisheries in the world. These are river trout (Rainbow trout - Oncorhynchus mykiss), brook trout (Brown trout - Salmo trutta), and brown trout (Brook trout - Salvelinus fontinalis). Currently, river trout breeding dominates global production. Its cultivation has been mastered in almost all regions [8]. In the article, the water quality indicators were studied during high-density breeding of trout in the cage method at the “Golden Fish” fishery LLC, located in the Khojakent reservoir in the Tashkent region of Uzbekistan. This includes water temperature, dissolved oxygen content, and water hydrogen potential, as well as information on fish growth, development, nutrition, and reproduction.

The problem of anthropogenic impact of the Tudakul reservoir has not been spared. In the first years of the reservoir’s existence, its ichthyofauna was formed by the fish of the Zarafshan River, which were represented by both rheophiles and limnophiles, and initially it consisted of 11 aboriginal species and introduced fish. This paper gives a brief physical-geographical, hydrological, hydrochemical, hydrobiological characteristics of the Tudakul reservoir. An assessment of the ecological state of the reservoir, ichthyofauna and fish catch in it over the past decade is given. Recommendations for the rational use of the Tudakul reservoir are given.
