Multisampler - a new tool for use in sampling trawls

Abstract

The MultiSampler is a system to be mounted in sampling trawls to give better estimates and knowledge about fish stocks.The system is remotely controlled via a hydroacoustic link from the vcssel. It consists of a rigid steel fi-ame with three separate &ds replacing the standard codend in a sampling trawl. The MultiSampler takes three separate and unique samples from dierent depths in one trawl haul. The system is developed by the Institute of Marine Research and Scanmar. We are now at the end of the development period, and the system has already been used in regular abundance estimation cruises for spring spawning hemng.
