Mesopelagic fishes were sampled around Tristan da Cunha and St Helena in the South Atlantic from the RRS Discovery at depths down to 1000 m. Sampling was part of the Blue Belt Programme, a marine survey of British Overseas Territories funded by the United Kingdom Government. Thirteen species of mesopelagic fishes identified from 30 specimens were compared with two species (two specimens) collected from rock pools or surface water near the shore. The digestive tracts of all fishes were examined for microplastics. Additionally, one specimen of Opostomias micripnus (Günther, 1878) was analyzed after recovery from the stomach of a commercially fished species, Hyperoglyphe antarctica (Carmichael, 1819). One specimen of Anoplogaster cornuta was found to have ingested a bearded sea devil (Linophryne sp.), a cock-eyed squid (Histioteuthis sp.), a bolitaenid octopus, Japetella diaphana, remains of unidentifiable fish, crustaceans, and possibly salps. These prey items were also examined for microfibres. Both Histioteuthis sp. and Linophryne sp. had ingested fibers and these were considered “ingested particles” for A. cornuta. Neither shallow water dwelling species had ingested microplastics, whilst 11 of the 13 studied mesopelagic species were found to be contaminated. Overall, 66.7% of mesopelagic fishes were found to contain microfibres. Anthropogenic fibers were common especially viscose, a semi-synthetic material which is associated with sanitary products as well as other items.

在南大西洋的Tristan da Cunha和St Helena附近从RRS采样了中生鱼类 发现深度不超过1000 m。采样是“蓝带计划”的一部分，该计划是由英国政府资助的对英国海外领土的海洋调查。将从30个标本中鉴定出的13种中生鱼类进行了比较，并将其与从岩石池或海岸附近的地表水中收集的2种（两个标本）进行了比较。检查所有鱼类的消化道中是否含有微量塑料。另外，一个标本臭豆 （Günther，1878）在从商业捕鱼品种的胃中恢复后进行了分析， 南极hyperoglyphe（卡迈克尔，1819年）。一个标本角须按蚊 被发现摄入了胡子的海魔（亚油基 sp。），一只鸡眼乌贼（历史学家 sp。），一个bolitaenid章鱼， 贾帕氏菌，无法辨认的鱼，甲壳类动物和可能的胡sal的遗骸。还检查了这些猎物中的微纤维。两个都历史学家sp。和亚油基sp。摄入了纤维，这些被认为是“摄入的颗粒”山茱uta。两种浅水栖居物种均未摄入微塑料，而在研究的13种中生近缘物种中有11种被污染。总体而言，发现66.7％的中生鱼类含有微纤维。人为纤维是常见的，尤其是粘胶纤维，这是一种半合成材料，与卫生用品以及其他物品有关。
