CE0601 Fisheries Acoustic Survey

Prior to this a larval survey programme was carried out between 1981 and 1986. The stock in this area is composed of 2 spawning components (autum and winter), covering a large geographical area.

Spawning may extend over a 4 month period from late September through to late March (Molloy et al, 2000). Traditionally fishing activity has targeted spawning and pre-spawning aggrefations, no summer matjie fishery exists in this area, as is the case in the Celtic Sea. A project is currently underway to describe stock structure and discrimination of herring around Ireland.
