The clam Chamelea gallina (L 1758) represents an important shellfish resource along Mediterranean coasts and its progressive depletion has been ascribed both to the overexploitation of stocks and to environmental or anthropic stressors. In this context, the investigation on immune parameters could represent a valid approach to measure the clam homeostasis condition and its possible influence on population dynamics. On this basis, the innate immune system, mainly represented by hemocyte phagocytosis, was investigated in organisms of different size. The results indicated a better phagocytic response in larger clams, strictly related to a greater concentration of granulocytes. A such variation in hemolymph composition appeared not dependent on environmental or endogenous factors, but rather on clam aging.
有重要贝类资源的斑节拟对虾（L 1758）沿地中海海岸，其渐进性枯竭已归因于股票的过度开发和环境或人为胁迫。在这种情况下，对免疫参数的调查可能代表了一种有效的方法来衡量蛤的动态平衡条件及其对种群的可能影响。在此基础上，研究了不同大小生物体的先天免疫系统，主要由血细胞吞噬作用表示。结果表明，较大的蛤蜊具有更好的吞噬反应，这与粒细胞浓度的增加密切相关。这种血液成分的变化似乎不依赖于环境或内源性因素，而是依赖于蛤蜊的老化。
