In addition to temperature and water availability stress, climate change will bring new water quality challenges in freshwater systems, including increased dissolved organic carbon and toxic metal loads  . Harrod et al.  found that the two major inland fishery producers  will face significant stress in the future, a large group of countries that produce around 60% of total yield is projected to face medium stress, and a small group of 17 countries has the least severe repercussions . Climate warming may enhance northward colonisation of water bodies of commercial freshwater species in the Arctic, where there are few ecological competitors   but at the same time may also accentuate the age- truncation effect of harvesting, elevating the population's vulnerability to environmental perturbations . Detailed information on many of the most important inland fisheries is limited.
