The recruitment to the Norwegian spring-spawning herring have during the last twenty years been on a very low level. However, the size of the spawning stock has increased in recent years and in 1983 a rich year class was produced. The increase of the stock as well as development of new gears and methods was the background for a new project to study the recruitment mechanisms. The present report presents some preliminary results from a pilot study in April,1985. It deals with the horizontal and vertical distribution of herring larvae in relation to physical conditions as well as growth and diet.
