Abstract
The condition index is an important indicator of the physiological and health status, as well as the quality, of mussels. Standardised sampling and a suitable methodology for analysing the condition index of the Mediterranean mussel (Mytilus galloprovincialis) are the most important basis for longterm quality monitoring, enabling quality assessment of farmed mussels, sites and production areas, as well as comparison with other areas, regionally and beyond. Considering the growing need to highlight and define the quality of locally farmed mussels, a study was conducted to seasonally monitor the condition index (2008 – 2024) and determine the proximate composition (May 2023) of mussels in the Lim Bay - Navi mussel farm zone. For this purpose, the quality of the mussels was determined using a condition index based on the percentage of dried meat in the mass of the shells (CI), wet meat (MYw), cooked meat (MYc) and the shell incidence (SI) in the total mass of the mussels and the proximate composition of meat (proteins, fats, carbohydrates, water and ash). During the sampling of mussels, the basic oceanographic parameters (temperature and salinity) of the sea in the farming area were measured. A seasonal variation in condition index (CI) from 8.60% to 18.28%, wet meat percentage (MYw) from 16.54% to 29.30%, cooked meat percentage (MYc) from 14.92% to 23.32%, and shell incidence (SI) from 30.17% to 39.69% was observed, with the average annual values of these four condition index calculations being CI 10.96 ± 1.91; MYw, 23.82 ± 2..91; MYc 19.06 ± 2.33, and SI 37.03 ± 2.87. The analysis of fresh mussel meat revealed the following proximate composition: 9.37 ± 0.45% proteins, 2.54 ± 0.43% carbohydrates, 1.04 ± 0.22% fat, 2.58 ± 0.13% ash and 83.05 ± 1.52% water. The annual mean values of the applied condition index calculations and nutritional composition indicate a satisfactory quality of the mussels from the Lim Bay "Limska dagnja", which is comparable and similar to the values of mussels from other aquaculture areas of the Adriatic and the Mediterranean.
