Abstract
    The Continuous Plankton Recorder Survey provides the opportunity for studies on the ecology of fish Larvae over a wide area. All major stocks of herring can be distinguished from the geographical and seasonal distribution of their early larvae. There appears to be a single population of mackerel in the North Sea, and another to the west of the British Isles. Biue whiting, spawning over Rockall and Porcupine Banks, may represent a single population. The spawning of pelagic fish stocks in oceanic and transitional areas is closely associated with the biological spring, when food for the larvae is most plentiful. This may not hold true in neritic areas where plankton development is more regular, and less restricted, seasonally. Among several distinctive long-term trends are the decreasing numbers of herring larvae off the Norwegian coast and in the southern North Sea, reflecting declining stocks; an increase in the numbers of mackerel larvae in the North Sea daring the fifties, and a southerly swing in the distribution of the blue whiting larvae during the sixties. Possible links between natural changes in larval populations and plankton production cycles are considered.
