These enormous fish are the largest purely freshwater fish in the world (Sturgeon are larger, but they inhabit both fresh and saltwater). If nothing was done to decrease salt levels, such toxic overgrowths could occur again during a hot, dry summer, he said. Largest on record: 8 feet, 10 inches 646 pounds. Such a large growth of algae requires elevated salinity levels that could be reached only through industrial pollution, said IGB scientist Tobias Goldhammer. "We see that it rarely appears in the world," she said. Polish Climate Minister Anna Moskwa said at a news conference earlier on Friday that more research would be needed to determine the conditions that led to the algae's appearance. Research is still needed on the toxicity of the algae, and it is not yet clear whether humans and other animals could also be affected, the IGB said in a statement. She said a direct connection between the algae and the death of fish and molluscs in the river could be assumed.
