Benthic bycatch from dredge surveys for seed mussel (Mytilus edilus) stock assessment, Outer Ards, Northern Ireland

Latest version published by Marine Biological Association on May 21, 2019 Marine Biological Association

This dataset contains presence/absence information of infaunal bycatch from seed mussel stock (Mytilus edulis) assessment surveys off the Outer Ards Peninsula in Northern Ireland. The seed mussel survey is carried out each year and these surveys were carried out between 2017-02-21 and 2018-07-18. The dredge samples are taken from the DAERA Fisheries Protection Vessel Queen of Ulster (formally Banríon Uladh). The main aim of the seed mussel survey is to carry out a stock assessment of seed mussel in areas that are fished for these mussels. The stock assessment surveys use acoustic ground discrimination system (AGDS), dredge surveys (ground truthing) and then in areas where there appears to be high levels of seed mussel an underwater video camera sledge is towed from the RV Corystes for more ground truthing. It is important to note that the information in this dataset was not the key focus of these surveys.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 126 records. 2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
