- In the majority of European seas, the Marine Trophic Index (MTI) has been declining since the mid 1950s, which means that populations of predatory fish are declining and populations of smaller fish and invertebrates are increasing; this indicates that fisheries are not exploiting the resources sustainably (EEA, 2009).
- There are significant differences in the decline in MTI rates in the different seas (EEA, 2009).
