Herring Spawning Stock Survey Off West & North West Coasts This December

The Marine Institute’s Fisheries Ecosystems Advisory Services (FEAS) department will undertake a survey of herring off the West and North West Coasts from 1-10 December.

This survey is the fourth in a time series that is hoped will be developed into a long-term index of spawning/pre-spawning herring in ICES area 6a S/7b, for use in stock assessments in the future.

The overall 6a survey (6a N and 6a S/7b) is part of a collaborative partnership between Ireland, the Netherlands and UK (Scotland) that aims to improve understanding of the individual stock components of herring in 6a and 7b.

Next month’s survey will be conducted by the RV Celtic Voyager (callsign EIQN) using a towed body with two split-beam transducers (38 kHz and 120 kHz). The vessel will be trackable online during the survey.

In total around 1,100 nautical miles of cruise track will be undertaken with a mixture of parallel (spaced at 7.5 and 3.5 nm) and zig-zag transects. The vessel will display appropriate lights and signals.

Night operations will involve the towing of the two split-beam transducer. Fishing will take place opportunistically during daylight hours.

Contact details and co-ordinates of the relevant survey areas are included in Marine Notice No 50 of 2019, a PDF of which is available to read or download HERE.
