“…A small number of tools and methods (Adams et al, 1993; Bailey et al, 2018; Jorgenson et al, 2018; Lang et al, 2017; Munkittrick, 1992; Muttray et al, 2021; Tetreault et al, 2011) have been used to evaluate the health of wild fish in their natural environments, but there is no standardized tool for field‐based health assessments, especially with regard to pathologies of xenobiotic etiology. The fish health assessment index (HAI) described by Adams et al (1993) is an extension of one of the original field dissection methods (Goede & Barton, 1990) and a quantitative health index that allows statistical comparisons of fish health assessed in natural settings.…”

Fish serve as indicators of exposure to contaminants of emerging concern (CECs) ‐ chemicals such as pharmaceuticals, hormones, and personal care products – which are often designed to impact vertebrates. To investigate fish health and CECs in situ, we evaluated the health of wild fish exposed to CECs in waterbodies across northeastern Minnesota with varying anthropogenic pressures and CEC exposures: waterbodies with no human development along their shorelines, those with development, and those directly receiving treated wastewater effluent. Then, we compared three approaches to evaluate the health of fish exposed to CECs in their natural environment: a refined fish health assessment index (rFHI), a histopathological index, and high‐throughput (ToxCast) in vitro assays. Lastly, we mapped adverse outcome pathways (AOPs) associated with identified ToxCast assays to determine potential impacts across levels of biological organization within the aquatic system. These approaches were applied to subsistence fish collected from the Grand Portage Indian Reservation (GPIR) and 1854 Ceded Territory in 2017 and 2019. Overall, 24 CECs were detected in fish tissues, with all but one of the sites having at least one detection. The combined implementation of these tools revealed that subsistence fish exposed to CECs had histological and macroscopic tissue and organ abnormalities; although, a direct causal link could not be established. The health of fish in undeveloped sites was as poor, or sometimes poorer, than fish in developed and wastewater effluent‐impacted sites based on gross and histologic tissue lesions. AOPs revealed potential hazardous pathways of individual CECs to fish. A better understanding of how the health of wild fish harvested for consumption is affected by CECs may help prioritize risk management research efforts and can ultimately be used to guide fisheries management and public health decisions.
