Herring Larval Surveys off the West and North West Coasts

Herring larval surveys provide an index of the size of the herring stock which spawns each October and November along the Donegal, Mayo and Galway coasts. This index is then used as a basis for determining the total allowable catch (TAC) for the stock and subsequently the national quotas. As well as detecting trends which occur in the stock sizes the surveys also indicate the locations and the times at which the main spawnings occur. This Leaflet gives details of the distribution of larvae and seasonal variations in their abundance. It is intended to extend the area covered by these surveys in an effort to improve the reliability of the estimates of the stock sizes obtained.
