Large numbers of Micromesistius poutassou were caught in the English Channel during the spring of 1979. Later in 1979 and in the early months of 1980 smaller numbers were recorded from the southern North Sea where this species has rarely been recorded before. The M. poutassou were accompanied by small numbers of T. esmarkii in the eastern English Channel but no T. esmarkii were found in the southern North Sea. T. esmarkii were taken off Plymouth on two occasions in 1977 and more regularly since 1979. M. poutassou has been recorded there sporadically since 1957. Both species were caught in considerable numbers around the Scillies in 1977 and 1978. The invasion of the English Channel by M. poutassou in 1979 may have come from the Bay of Biscay rather than the Celtic Sea, but the appearance of T. esmarkii in the Plymouth area since 1977 may be a result of changes in the ecosystem since 1964.
