Abstract
The fish production in the Republic of Macedonia is based on performing commercial fishing from natural and enlarged artificial lakes - reservoirs, as well as, in fish breeding
facilities, or aquaculture. The main purpose of research in this paper is establishing production of the rainbow trout (Oncorhynchus mykiss) in one of the biggest coldwater
fishponds, located in Pelagonia Region. Besides the main purpose of research, there are other purposes which are directly related to the production of the rainbow trout, such as determining food consumption to produce the appropriate amount of fish in a given period, the fish growth in a given period and conversion.
The coldwater fishpond Strezhevo is located near Bitola (Macedonia) and functions within the PC "Strezhevo"- Bitola.
In 2014, in the fishpond Strezhevo 12.588 kg or 85.252 pieces of pre consumable fish, as well as, 3874 kg or 14.761 pieces of consumable fish are produced. Also, 90.891 kg fish food is spent and 60.932 kg fish growth is gained. The conversion is 1.49. In 2015, 3.759 kg or 23.759 pieces of pre consumable fish, as well as, 18.508 kg or 63.072 pieces of consumable fish are produced. Also, 71.110 kg fish food is spent and 51.815 kg fish growth is gained. The conversion is 1.37. In 2016, 14.032 kg or 162.086 pieces of pre consumable fish, as well as, 6.812 kg or 33.408 pieces of consumable fish are produced. Also, 43.495 kg fish food is spent and 36.880 kg fish growth is gained. The conversion is 1.18.
It is noticed that high fish productivity is conditioned by a proper diet including all of the components that help for intensive growth and development while preventing the occurrence of fish diseases. With properly normalized food, the cultivation of maximum fish production per unit area, as well as, minimum consumption of food can be achieved.
