- Parasite diversity in plaice (Pleuronectes platessa): potential tool for stock identification in Icelandic waters?Publication . Pubert, Eve-Marine; Randhawa, Haseeb S.Understanding the stock structure of a commercial species is essential for sustainable 36 management. Failure to do so can lead to the depletion of regional sub-populations, erosion 37 of genetic diversity, and ecosystem services loss. Plaice, Pleuronectes platessa, is a 38 commercially exploited species inhabiting the continental shelf around Iceland. Despite a 39 tagging study providing support for strong spawning site and feeding ground fidelity, and 40 otolith microstructure analysis revealing local population structure, plaice is managed as a 41 single stock in Icelandic waters. Here, we describe and quantify the parasite fauna of plaice, 42 and assess the potential of parasites as biological tags for stock identification of plaice in 43 Icelandic waters. A total of 82 plaice were sampled from different geographical locations 44 (North and South) and seasons (summer and winter) in Iceland. Our sampling identified 11 45 parasites, five of which are new parasite records for plaice in Icelandic waters: the trematodes 46 Zoogonoides viviparus (adults) and Rhipidocotyle sp. (metacercariae), and the nematodes 47 Contracaecum osculatum (larvae), Dichelyne sp. (adults), and Hysterothylacium aduncum 48 (larvae and adults). Additionally, we recovered metacercariae of the trematode genus 49 Apatemon, which has not been recorded previously from plaice. Two parasites were 50 identified as potential biological tags for stock identification, namely the nematode A. simplex 51 and the trematode Z. viviparus. Our findings support a complex stock structure for plaice in 52 Icelandic waters and the need for an integrative strategy to stock identification to provide fine 53 spatial scale data required to inform fisheries managers.
