This study investigated the distribution and utilization of Mytella strigata in the Philippines thru site surveys, focus group discussions, and interviews. Initially reported in Manila Bay in 2014, results showed that this mussel species had spread to provinces mainly in the western and northern sections of Luzon Island. Interviews and focus groups revealed that Asian green mussel and oyster farming were affected by the non-indigenous species resulting in a reduction in harvest of farmed shellfish. As a result, local communities in traditional shellfish farming sites generally expressed negative perception towards the non-indigenous species as this was not regarded as a food item. In contrast, local fishers in non-traditional shellfish farming sites generally welcomed M. strigata as it provided food and livelihood opportunities. These results show that the emergence of M. strigata in the Philippines had both positive and negative consequences on the livelihoods of affected local communities. However, local and national agencies had been slow in recognizing the threat of M. strigata on Asian green mussel and oyster industries. These results, therefore, provide useful information to address issues related to the non-indigenous mytilid species and signify the need to review local and national policies in response to the emergence of potentially invasive species.

这项研究通过现场调查，焦点小组讨论和访谈，调查了菲律宾Mytella strigata的分布和利用情况。该贻贝物种最初于2014年在马尼拉湾报道，结果表明该贻贝物种已扩散到主要在吕宋岛西部和北部的省份。访谈和焦点小组透露，亚洲青口贻贝和牡蛎养殖受到非本土物种的影响，导致养殖贝类产量下降。结果，传统贝类养殖场的当地社区普遍对非本地物种表示消极看法，因为这不被视为食品。相比之下，非传统贝类养殖场的当地渔民通常都欢迎条藻因为它提供了食物和生计机会。这些结果表明，菲律宾条纹线虫的出现对受影响的当地社区的生计既有正面的影响，也有负面的影响。但是，地方和国家机构在认识到Strigata斑纹对亚洲青口贻贝和牡蛎产业的威胁方面反应迟钝。因此，这些结果提供了有用的信息，以解决与非本土类Mytilid物种有关的问题，并表明有必要针对潜在入侵物种的出现，审查地方和国家政策。
