5203 |a"Acoustic surveys of the 4WX herring stocks during winter and summer, 1981, obtained stock size estimates of 408 000 t and 201 000 t, respectively. Sampling error and unavailability of the stock to survey. during the summer period meant that there is a large amount of uncertainty In these estimates. Despite this, many of the problems associated with these surveys appear tractable and the continuation of these surveys should provide cost-effective estimates of the abundance of this herring stock."
