Climate change means that the fish are smaller

Climate change means that the fish are becoming smaller, as scientists have discovered the Leibniz Institute of Marine Sciences (IFM-GEOMAR) in Kiel (northern Germany) in collaboration with French researchers

The study, based on measurements taken in different areas of water, such as the North Sea and Baltic countries, notes that global warming is also affecting the size of freshwater organisms. Scientists have observed that due to warming of the seas, the proportion of fish, bacteria and algae from large declines, while increasing the number of small species. "The body size of these bodies is crucial for animals to devour and those who are devoured by," he said Sommer.

Thus, the animals reach sexual maturity with little height, and an increase in small species could mean that more devour zooplankton. "And naturally diminishes the scientific value of the fishery because the fish are smaller," he said. The study was published in the journal "Proceedings," published by the National Academy of Sciences of United States.
