Table 1 and Figures 3 and 4, regardless of the parasite microhabitat (viscera or flesh) and season of capture, show the prevalence, mean abundance, and intensity of infection of anisakid L3 type I larvae in 10 fish species. A total of 361 (33.58%) specimens were parasitized. Out of the 10 different fish species examined in this research, 9 of them showed contamination with _Anisakis_ larvae. Only one fish species, _Solea vulgaris_, returned a negative result (Table 1). _Sparus aurata_ showed the lowest prevalence and mean abundance, followed by _Dicentrarchus labrax_ and _Sardinella aurita_ (Figures 3 and 4). Conversely, the highest prevalence and mean abundance were recorded in _Scomber japonicus_ and _Scomber scombrus_, respectively (Figures 3 and 4), which also exhibited high intensities (20,330 and 24,982, respectively; Table 1). Quantitative descriptors of the parasite populations according to the microhabitat of parasitation are presented in Table 2. Both in the viscera and flesh, _Sparus aurata_ was the fish infested with _Anisakis_ the least, while _Scomber japonicus_ was the heaviest. Overall, both the prevalence and mean abundance were higher in the viscera (prevalence = 33.58 \(\pm\) 1.4%; abundance = 61.15 \(\pm\) 130.31 helminths/host) than the flesh (prevalence = 27.91 \(\pm\) 1.4%; abundance = 3.74 \(\pm\) 10.39 helminths/host; \(p\)!0.001). Regardless of the fish species, the season of capture affected the susceptibility to infection. The highest prevalence and mean abundance were recorded in the summer and spring, with the lowest being in the winter (\(p\)! 0.05; Tables 3 and 4). In particular, the differences in prevalence were statistically significant in _Sardinella aurita_, where one season (winter) returned a negative result (\(p\)! 0.05; Table 3). Differences in the mean abundance were found in several species; _Engraulis encrasicolus_, _Scomber japonicus_, and _Scomber scombrus_ had about half the number of larvae in winter than in summer and spring (\(p\)! 0.05; Table 4). \begin{table}
