The Philippines is an archipelago that relies on marine resources. Butuan Bay in the Philippines supports aquaculture, which can contribute to and can be impacted by plastic pollution. However, the microplastics (MP) in milkfish, an important aquaculture species in the area, are yet to be ascertained. This study determined the prevalence of microplastics in the surrounding seawater and in the gut of adult milkfish from cages in Butuan and Nasipit in Butuan Bay. Water samples in Nasipit and Butuan contain 0.20 items/L and 1.00 items/L, respectively. MPs in milkfish in Butuan (10.27 items/individual) were significantly higher than in Nasipit (5.40 items/individual). A total of 235 MPs in 29 out of 30 fish samples (97 %) from the two sites were detected. The dominant MP shape and color were fiber and blue, respectively. The presence of microplastics in the milkfish may indicate a possible risk to the fish species and human health.

菲律宾是一个依赖海洋资源的群岛国家。菲律宾的布端湾支持水产养殖，水产养殖可能导致塑料污染，也可能受到塑料污染的影响。然而，该地区重要的水产养殖品种遮目鱼体内的微塑料（MP）仍有待确定。这项研究确定了武端湾和纳西皮特周围海水和成年遮目鱼肠道中微塑料的流行情况。Nasipit 和 Butuan 的水样分别含有 0.20 个项目/L 和 1.00 个项目/L。武端市遮目鱼的 MP（10.27 项/个体）显着高于纳西皮特（5.40 项/个体）。两个地点的 30 个鱼类样本中有 29 个（97%）共检测到 235 个 MP。主要的 MP 形状和颜色分别是纤维和蓝色。遮目鱼中存在微塑料可能表明对鱼类和人类健康可能存在风险。
