In the past few years, non-native blue crab has been expanding its range in the Adriatic and Mediterranean Seas. However, when non-indigenous species establish a lasting presence in a novel ecosystem and actively expand into other regions, posing potential risks to local biodiversity and economic harm, they are classified as invasive species. For this study, two different batches of blue crabs were collected: one from the Mediterranean Sea and the other from the Adriatic coast area. Considering the negative ecological impact that blue crab has had and continues to have on the Italian coasts, this work was aimed to evaluate the characteristics of the Adriatic Sea "variant"; another goal was to propose the potential use of blue crab as a commercially profitable source due to its organoleptic characteristics. Data obtained revealed a high protein content, a good lipid profile, a low number of plastic particles, and the absence of toxic metals and pathogenic microorganisms. A deep statistical analysis was conducted to compare different portions of blue crab from the Adriatic and Mediterranean Seas. The results suggest that is beneficial for human consumption and represents a valuable seafood, and its carapace could be used as compliant feed for aquaculture due to its metal composition and microbiological content.
在过去几年里，外来蓝蟹一直在亚得里亚海和地中海扩大其活动范围。然而，当非本地物种在新的生态系统中长久存在并积极扩散到其他地区，对当地生物多样性构成潜在风险并造成经济损害时，它们就被归类为入侵物种。在本研究中，收集了两批不同的蓝蟹：一批来自地中海，另一批来自亚得里亚海沿岸地区。鉴于蓝蟹对意大利海岸已经并仍在产生负面生态影响，这项工作旨在评估亚得里亚海“变种”的特征；另一个目标是鉴于蓝蟹的感官特性，提出将其作为商业盈利来源的潜在用途。获得的数据显示，蓝蟹蛋白质含量高、脂质分布良好、塑料颗粒数量少，且不含有毒金属和致病微生物。进行了深入的统计分析，以比较来自亚得里亚海和地中海的不同部位的蓝蟹。结果表明，蓝蟹有利于人类食用，是一种有价值的海产品，由于其金属成分和微生物含量，其甲壳可用作符合要求的水产养殖饲料。
