The impacts of climate change on fish growth: A summary of conducted studies and current knowledge

Global climate change is increasingly and profoundly threatening fishes, resulting in an uncertain future for both wild fish diversity and global fisheries. Understanding how fish growth responds to changing environments is essential for indicating and predicting the impacts of climate change on fis...
