However, the resources required to record individual body weights for benthic animals, where the number of individuals can reach several thousand in a square metre, are often prohibitive. Here we present morphometric (length-weight) relationships for 216 benthic species from the North Sea to permit weight estimation from length measurements. These relationships were calculated using data collected over two years from 283 stations.

Of these, data on the sampling stations are given. As a result of the identification of nereidid spe- cimens, three new records for the Iberian Peninsula were found, Ceratonereis vittata Langerhans, 1884, Neanthes rubicunda (Ehlers, 1864) and Nereis perivisceralis Claparède, 1864.

  • A Check-List of Polychaete Species from the Black
    J. Black Sea/Mediterranean Environment Vol. 18, No.1: 10-48 (2012) REVIEW ARTICLE A check-list of polychaete species (Annelida: Polychaeta) from the Black Sea Güley Kurt Şahin1*, Melih Ertan Çınar2 1Department of Biology, Faculty of Arts and Sciences, Sinop University, 57000, Sinop, TURKEY 2Department of Hydrobiology, Faculty of Fisheries, Ege University, 35100, Bornova- Izmir, TURKEY *Corresponding author: [email protected] Abstract Polychaetes from the Black Sea were reviewed based on the available literature. Lists of the valid species, re-assigned species and dubious species (nomen dubium or indeterminable species) reported from the region are provided. The checklist comprises 238 valid species belonging to 45 families. Twenty three species belonging to 8 families were considered as nomen dubium or indeterminable. Fifty-one species reported from the Black Sea between 1868 and 2011 have been synonymised with other species. Among the Black Sea countries, the coast of Bulgaria is represented by the highest number of polychaete species (192 species), followed by the coasts of Ukrania (161 species) and Romania (115 species). The highest number of species (119 species) were found on sandy substratum, the lowest number of species (7 species) on sponges. Nine alien polychaete species (Hesionides arenaria, Streptosyllis varians, Glycera capitata, Nephtys ciliata, Polydora cornuta, Prionospio pulchra, Streblospio gynobranchiata, Capitellethus dispar and Ficopomatus enigmaticus) were reported from the Black Sea up to now. The most speciose families in the area were Syllidae (32 species), Spionidae (31 species), Phyllodocidae (16 species) and Nereididae (15 species). By presenting a complete overview of the species reported from the area, this work summarises our current knowledge about the diversity of the Black Sea polychaetes and provides a database for future studies.

Clarke Ecosystem impacts of intertidal invertebrate harvesting: from benthic habitats to bird predators. Intertidal harvesting of marine invertebrates has significant potential to come into conflict with the interests of nature conservation. This is particularly so for overwintering shorebirds that rely heavily on invertebrate prey to maintain body condition throughout the winter and to fuel migration towards breeding grounds. Harvesting activities in these areas therefore require careful management to achieve sustainability and to maintain healthy ecosystem functioning. This thesis investigates impacts of intertidal harvesting on benthic habitats and invertebrate communities as well as the potential impacts of harvesting on shorebird populations. Implications for management of inshore and intertidal fisheries are discussed. A meta-analysis investigated the response of key invertebrate prey groups to different gear types used in different intertidal habitats. Hand gathering most severely reduces prey abundance, which is likely to be due to the accuracy of harvesting with these gear types, while recovery trends vary between different combinations of gear and habitat and taxonomic groups.
