在新西蘭南部水域，一項為期兩年的研究發現，75% 的商業捕撈魚類如紅擬褐鱈及石首䱵體內都含有微膠粒。在這些魚體內發現塑膠有98%小於 3 毫米。這些塑膠主要來自聚乙烯及聚丙烯，是常用於生產一次性器具、塑料袋、膠樽、漁網及繩索的塑膠。
A two years study in southern New Zealand waters discovered microplastics inside 75% of the commercially caught fishes including red cod and tarakihi. 98% of the plastic found inside these fish were less than 3mm.
