چکیده
The objective of changing the simple exploitation of fish stocks to highly efficient fish farms in lakes and reservoirs is to improve the productivity of inland freshwater fish. The small- and medium-sized lakes can be used to increase the production of farmed fish with lake management. Therefore, this study proposed to investigate the production and economic efficiency of carp in lake commercial fish farms. In this investigation, the results of carp farming experiments in fish farms in small lake commercial fish farms (LCFF) are evaluated using advanced methods and techniques.The research was carried out based on the Voroshilovsky reservoir, which operated in the LCFF mode. The farm had hatchery and carp fry ponds for expanding fingerlings based on the "Scientific and production center of fishery" LLP from 2019 to 2020. This study was performed on different types of common carp and herbivorous fish (grass and silver carp), and sexual products were collected in fried ponds and the Voroshilovsky reservoir.The absolute growth gain of common carp, silver carp, and grass carp were 301.00, 300.40, and 577.00 grams, respectively, and their mean daily weight gain values were 2.50, 2.50, and 4.80 grams. Common carp recorded the highest level of planned fish productivity (169.30 kg/ha), and the lowest level of this trait was grass carp (43.50 kg/ha). Data of mean weight and body length of common carp, grass carp, and silver carp fishes showed a variation of 4.55 kg and 56.25 cm, 6.06 kg and 75.50 cm, as well as 6.30 Kg and 75.05 cm, respectively. This difference can be justified according to the variance of fish length, which on average, 80 grams of weight is obtained per centimeter of fish length. The economic efficiency of carp was calculated, and the net profit was determined at more than 50% of total income.According to the net profit indicator, due to the implementation of a part of the fingerlings, the carp reared in the pond area; as a result, this method is profitable and accounts for 104% of the total planned economic profit. Therefore, fish production from aquaculture can rise to 10 times to maintain high-quality food security and other essential nutrients, provide job opportunities, and cash income to help job-seeking youth.
