The comparison of qualitative composition of the muscle tissue of brown trout, rainbow trout and brook trout
Journal Title: Біологія тварин - Year 2018, Vol 20, Issue 1
Abstract
Intensification and development potential of the aquaculture sector have created problems relating to the ecological purity and quality of the final fish product. In the conditions of Ukraine, there is extremely little information regarding the objects of trout fishing. Therefore, the purpose of our work was to investigate and analyse individual chemical and biochemical parameters of muscle tissue of commercially profitable and valuable indigenous species of salmon fish grown under the same conditions. As the materials for research the brown trout (Salmo trutta m. fario), rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis) in the age of a year and a half (1+) served. According to the results of the research, moisture composition in the muscular tissue of brown trout was higher compared to rainbow trout and brook trout (P<0.01). In brook and rainbow trout, the amount of the protein is significantly higher (P<0.01) than in brown trout. The content of ash in brook trout, brown and rainbow trout was 1.23 %, 1.16 %, 1.25 %, respectively. The percentage of total lipids in the muscle tissue of rainbow trout and brook trout was significantly higher than in brown trout (P<0.01). The higher content of free cholesterol and mono- and diacylglycerols in brook trout compared to the brown and rainbow trout (P<0.01) was noticed.
