ABSTRACT

A summary is presented of the anthropogenic debris recorded up to 2020 in stomachs of marine fishes from New Zealand waters. This material (mainly plastics) was found in the stomachs of 28 species, with 24 of these species identified in two studies alone. Most of the New Zealand records were not identified in recently published global assessments of plastic ingestion by fish; the likely reasons for this are discussed. Consumption of anthropogenic debris by fish in New Zealand waters is probably a widespread phenomenon, particularly for inshore demersal species with an algal dietary component and for offshore pelagic species that prey on gelatinous biota. Based on currently available data, this behaviour may occur relatively less frequently in deeper water demersal habitats, although no studies investigating the ingestion of microplastic particles by fish in this section of the New Zealand marine environment have yet been completed. The likelihood of identifying plastics in fish diets is strongly dependent on the analytical method used.

新西兰周围海洋鱼类摄入人为碎片

摘要

总结了截至 2020 年在新西兰水域的海洋鱼类胃中记录的人为碎片。在 28 个物种的胃中发现了这种材料(主要是塑料),仅在两项研究中就发现了其中 24 个物种。在最近发表的关于鱼类摄入塑料的全球评估中没有发现大多数新西兰的记录;讨论了造成这种情况的可能原因。新西兰水域鱼类消耗人为碎片可能是一种普遍现象,特别是对于具有藻类饮食成分的近岸底栖物种和捕食凝胶状生物群的近海中上层物种而言。根据目前可用的数据,这种行为在较深的水底层栖息地发生的频率可能相对较低,尽管尚未完成对新西兰这部分海洋环境中鱼类摄入微塑料颗粒的研究。识别鱼类饮食中塑料的可能性在很大程度上取决于所使用的分析方法。
