Abstract

The purpose of this research is to establish the differences between the production characteristics of the golden rainbow trout (Oncorhynchus mykiss Stevanovski, 1987) and the standard rainbow trout (Oncorhynchus mykiss Walbaum, 1792), that are bred in the fish farms “Banjica” and “Vrutok” – Gostivar, Repubilc of Macedonia.
The examinations have been done in the aforementioned fish farms “Banjica” and “Vrutok” – Gostivar, and the entire production cycle has been comprised:
-incubating of the fertilized fish roe and its placement in incubators for the process of incubation, the course of the incubation, the beginning of peeling and the perсiod of resorbing of bilious bag of the larva;
-first feeding of fish and the entire breeding period of the offspring in the fish farm “Banjica”, as a first breeding phase;
-second production period - the fish fattening in fish farm “Vrutok” reaching the final consuming weight of fish.
The nutrition of fish is performed with extruded food, a product of the company Skreting SpA, Mozzekane - Verona, Italy, with a granulation of the food depending of the individual weight of fish that is being fed.
The final period marked as a second phase i.e. the fattening period has provided the following production results:
-As of golden rainbow trout, it has been registered a total production of marketable size golden rainbow trout in amount of 4.365,43 kg with an individual weight of 258.60 kg, while as of standard rainbow trout it has been registered a total fish production in amount of 3.541,21 kg, which is less for 824.22 kg or 23.28 %.
-The individual weight per piece regarding golden rainbow trout measured in the same period results as 258.60 g, appearing as 40.80 g larger compared with the standard rainbow trout (217.8 g) or 18.73 %.
