“…At the German coast, the subtidal cliffs of the island of Helgoland (North Sea, German Bight) harbour a geographically and ecologically isolated small population of H. gammarus in an area of about 33 km 2 (Ulrich et al, 2001;Triantafyllidis et al, 2005). The first record of lobster landings from commercial fishery reported a yield of around 37,000 lobsters in 1615 and 40-50,000 animals per year in 1790s.…”

a b s t r a c tFrom 2000 to 2005 about 5400 one-year-old hatchery-reared lobsters (Homarus gammarus) were tagged and released at the rocky island of Helgoland, North Sea. To date, 1-8% of the different release cohorts were recaptured in the field and 8-19% of these lobsters were recaptured from the semi-open area of the outer harbour. The recaptured lobsters indicated good development and growth conditions. The smallest berried females caught were 83 mm carapace length and 4 years old. The proportion of cultured lobsters to all measured lobsters captured around the island was 3-8% in the years [2007][2008][2009]. The population size of two cohorts was assessed using the Lincoln-Peterson method and the estimated survival rate averaged 30% and 40%. Minimum landing size of cultured lobsters was reached after 4-7 years. Cultured lobsters showed strong fidelity to their release sites, and thus remained around the island of Helgoland. A basis has been laid to enhance this endangered lobster population by means of a large scale restocking programme.

“…European lobsters Homarus gammarus are large decapod crustaceans of ecological and commercial importance, distributed from the north of Norway to Morocco in North Africa (Triantafyllidis et al 2004). Historically, the Skagerrak region supported a viable population of the species, but over the last 30 to 40 yr catches have plummeted (Agnalt et al 2007).…”

European lobster Homarus gammarus in Norway has been in decline over the last 30 to 40 yr, and the species is currently red listed according to International Union for Conservation of Nature criteria. In 2006, experimental lobster reserves were established in the coastal Skagerrak, southern Norway, allowing for studies in the absence of disturbance by fishing gear. We present behavioural data from individual lobsters (n = 10) within 2 of the reserves. These data were obtained from data storage tags which logged in situ temperature and depth of specific individuals for up to 1 yr. To the best of our knowledge, these are the first direct measurements of depth obtained from freely behaving lobsters. Net movement exhibited by recaptured lobsters, measured as the distance between global positioning system positions recorded at the site of capture and recapture ranged from 15 to 580 m. Lobsters used habitats within a depth range of 1 to 57 m, and experienced sea temperatures ranging from 2°C during late winter (February to March) to 18°C during late summer (August to September). Lobster activity levels declined from September, reaching a minimum during February and March. From April, activity levels resumed. Seasonal variation in activity was correlated to water temperature (r 2 = 0.55). Lobsters were more active during nighttime than during daytime, and there was a tendency for lobsters to reside in more shallow water during nighttime versus daytime. The present study suggests that future reserves for European lobster should be designed to include deeper habitat (30 to 50 m) in areas where such habitat exists when the management objective is long-term protection.

“…Many studies have used indirect genetic tools such as mitochondrial DNA (mtDNA), nuclear DNA or a combination of the two to analyze genetic structure in high dispersal Atlanto-Mediterranean invertebrates (e.g., Féral et al 1995;Zane et al 2000;Launey et al 2002;Diaz-Almela et al 2004;Duran et al 2004a;Roman and Palumbi 2004;Stamatis et al 2004;Triantafyllidis et al 2005;Peijnenburg et al 2006;Calderon et al 2008). Differing conclusions regarding the influence of the Atlantic-Mediterranean division on population structuring were drawn in these studies depending not only on the species investigated but also on the genetic markers used and the sampling pattern.…”

“…Restriction fragment length polymorphism (RFLP) of mtDNA in the Norway lobster Nephrops norvegicus, for example, showed no genetic differentiation between the Atlantic and the Mediterranean (Stamatis et al 2004). However, pronounced differentiation between Atlantic and Mediterranean populations was detected in the closely related European lobster Homarus gammarus (Triantafyllidis et al 2005) using also RFLP of mtDNA. Two other crustaceans, the high dispersal green crab 3 Carcinus maenas (Roman and Palumbi 2004) and the pelagic Northern krill Megenyctiphanes norvegica (Zane et al 2000), again showed genetic differentiation between the basins based on mtDNA sequences.…”

Genetic structure of the high dispersal Atlanto-Mediterreanean sea star Astropecten aranciacus revealed by mitochondrial DNA sequences and microsatellite loci AbstractTo investigate the impact of potential marine barriers on gene-flow in high dispersal marine invertebrates, we assessed the population genetic structure of the sea star Astropecten aranciacus. Samples were obtained from nine locations within the Atlantic and the Mediterranean Sea including populations east of the Siculo-Tunisian Strait. We obtained both DNA sequence data of the mitochondrial control region and genotype data at four microsatellite loci. Both markers were highly polymorphic and showed a great level of genetic diversity. Genetic differentiation between populations (F (ST)) was in general low, particularly for nuclear data, as is often the case in high dispersal marine invertebrates. Nevertheless, both marker sets indicated a significant genetic differentiation of the population from the island of Madeira to most other populations. Our results also demonstrate a clear pattern of isolation-by-distance supported by both mitochondrial and nuclear markers. Therefore, we conclude that larval dispersal of A. aranciacus is somewhat limited even within the basins of the Atlantic, the west Mediterranean and the east Mediterranean. Microsatellite loci further revealed genetic differentiation between the three basins; however, it is not clear whether this is truly caused by marine barriers. Genetic differentiation between basins might also be a result of isolation-by-distance allowing for any grouping to be significant as long as geographical neighbors are clustered together. Although levels of genetic differentiation were less pronounced in mirosatellite data, both datasets were coherent and revealed similar patterns of genetic structure in A. aranciacus. 1Genetic structure of the high dispersal Atlanto-Mediterreanean sea star Astropecten aranciacus revealed by mitochondrial DNA sequences and microsatellite loci Deborah E.
