Sažetak
Mediterranean scallop (Pecten jacobaeus L.) is commercially exploited in the Northern Adriatic. The aim of this study was to determine the biochemical properties of the tissues (muscle, gills, gonad and hepatopancreas) during yearly seasons defined by the sea temperature. Concentrations of Ca, Mg, cholesterol (CHOL), glucose (GLU) and triglycerides (TRIG) were analyzed. The concentration of measured properties varied between the investigated tissues and between seasons. Ca and Mg levels were the highest in summer and winter in gonad (Ca, Mg) and hepatopancreas (Ca). Tissue concentrations of CHOL, GLU and TRIG were not uniform in tissues or seasons: levels of GLU were elevated in gonadal tissue in the summer and in hepatopancreas in the fall. TRIG levels varied in gonad and hepatopancreas tissues in comparison to other tissues, while CHOL was significantly higher in gonad (autumn) and hepatopancreas (winter). Scallops under study have shown the maximum muscle energy reserves correlate with the maximum autumn gonadosomatic index. Although their nutritional reserves, according to the literature, are primarily stored in muscle and hepatopancreas, this study found that levels of CHOL, GLU and TRIG were the highest in hepatopancreas and gonad. The study thus confirmed the influence of seasons on the levels of biochemical properties which are relevant for ionic homeostasis, reproduction control, catabolism of protein and energy reserves.
