Mussels (Mytilus spp.) are worldwide utilized in marine biomonitoring by a multi-biomarker approach. However, for a correct interpretation of different biomarker responses, information is needed on their natural seasonal variability due to environmental/physiological factors. In this work, the seasonal variations of different biomarkers were investigated in M. galloprovincialis from 4 different sites from the gulf of La Spezia (Ligurian sea, Italy), an intensive rearing area in the north-western Mediterranean near La Spezia harbor, an important commercial and touristic port. Lysosomal membrane stability-LMS, stress on stress-SoS, phagocytosis, tissue metallothionein-MT content, oxidative stress related enzyme activities (GST, catalase), and nitric oxide (NO) production were evaluated. The results underline the importance of LMS and SoS as core descriptors of the mussel health status in relation to seasonal variations in temperature and reproduction. These data represent the baseline information for ongoing biomonitoring studies related to dredging activities in this area.
贻贝（紫贻贝属）通过多生物标志物方法在全球范围内用于海洋生物监测。然而，为了正确解释不同生物标志物的反应，需要了解由于环境/生理因素导致的其自然季节性变化信息。在这项研究中，对来自意大利利古里亚海拉斯佩齐亚湾4个不同地点的加利福尼亚贻贝不同生物标志物的季节性变化进行了调查，该地区是地中海西北部靠近拉斯佩齐亚港的一个集约化养殖区，拉斯佩齐亚港是一个重要的商业和旅游港口。评估了溶酶体膜稳定性（LMS）、应激应激（SoS）、吞噬作用、组织金属硫蛋白（MT）含量、氧化应激相关酶活性（GST、过氧化氢酶）和一氧化氮（NO）产生。结果强调了LMS和SoS作为贻贝健康状况与温度和繁殖季节性变化相关的核心描述符的重要性。这些数据代表了该地区正在进行的与疏浚活动相关的生物监测研究的基线信息。
