The purpose of this study was to test the effects of high-CO2 exposure on wound healing rates in an elasmobranch fish (Urobatis jamaicensis). Small dermal injuries (8 mm biopsy) closed by 22 days post-wounding with a decrease in haematocrit. High-CO2 exposure (ΔpH = 1.4) did not influence healing rate or haematocrit. Combined, these data provide evidence that minimally invasive scientific procedures have short-term impacts on elasmobranch fishes even during exposure to a chronic stressor. Therefore, wound healing rates may not be strongly impacted by ocean acidification (ΔpH = 0.4). This article is protected by copyright. All rights reserved.

高CO 2 暴露不会损害韧带鱼的伤口愈合

本研究的目的是测试高 CO2 暴露对 elasmobranch 鱼 (Urobatis jamaicensis) 伤口愈合率的影响。小的皮肤损伤（8 毫米活检）在伤口后 22 天闭合，血细胞比容降低。高 CO2 暴露（ΔpH = 1.4）不影响愈合率或血细胞比容。综合起来，这些数据提供的证据表明，即使在暴露于慢性压力源的情况下，微创科学程序也会对硬鳃鱼类产生短期影响。因此，伤口愈合率可能不会受到海洋酸化（ΔpH = 0.4）的强烈影响。本文受版权保护。版权所有。
