| During spring 1984 large ichthyoplankton surveys were performed to determine the spawning period and the spawning places of the sole in the Southern Bight of the North Sea. In March and April most eggs were found close to the Belgian coast and the coast of Brittany, which agrees with results of previous plankton surveys. In the second of the surveys, however, high densities were also found at stations about 50 km from the coast -in the open sea. An attempt is made to explain whether these early eggs were laid in the locality, contrary to what is normally accepted, or drifted there from the Belgian or the English coast. |
