With regard to mussel age in Mali Ston Bay, one-way ANOVA analysis indicated significant (p \(<\) 0.05) differences in tissue weight (p = 0.000 *), length (p = 0.000 *), and CI (p = 0.014 *) but no significant difference in EOM content (p = 0.970). Temporally, ANOVA analysis revealed significant differences only in EOM (p = 0.015 *; Table 1). Statistically, a positive relation was observed in 1-year-old mussels for biological parameters, revealing a significant relationship between tissue weight and CI (r = 0.949 *). Regarding the 2-year-old mussels, CI showed low negative relationship with length (r = \(-\)0.246) and a high negative relationship with EOM content (r = \(-\)0.746; Table 2) that may be primarily associated with the quality of environmental conditions in Mali Ston Bay and mussel reproductive status. In Kastela Bay, with regard to mussel age, one-way ANOVA analysis (Table 1) indicated significant (p \(<\) 0.05) differences in tissue weight (p = 0.016 *), length (p = 0.000 *), and CI (p = 0.000 *), but no significant difference in EOM content (p = 0.108). Nevertheless, tissue weight (p = 0.894), shell length (p = 0.680), and CI (p = 0.201) showed no significant temporal variations except EOM content (p = 0.000 *). Spatial variation of tissue weight showed significant differences in tissue weight (p = 0.023 *) between S1 and S4. Moreover, significant differences were observed as well for CI (p = 0.000 *) between S1_S4, S2_S4, and S3_S4. No significant variations were observed for the shell length (p = 0.894) and EOM content (p = 0.218) (Table 1). Statistically, shell length was significantly related to tissue weight (r = 0.509 *) and CI (r = 0.386 *) but not to EOM content (r = \(-\)0.026) regarding 1-year-old mussels (Table 2). Moreover, tissue weight was highly related to CI (r = 0.949 *) and moderately to EOM content (r = 0.489 *). Furthermore, CI and EOM were positively correlated (r = 0.465 *), which could be primarily attributed to mussel reproductive stages and quality of food sources and environmental conditions [17; 21; 22]. Regarding 2-year-old mussels, tissue weight was significantly related to shell length (r = 0.617 *) and CI (r = 0.816 *), while CI was related to EOM content (r = 0.552 *) (Table 2).
