“…These reports indicate that Japan imports more bait species than other countries. It seems that the difference in the number of imported species is caused by the presence of domestic fishing grounds in Europe and the United States (Cunha et al, 2005;Sypitkowski et al, 2010).…”

Saito, H., Kawai, K., Umino, T. and Imabayashi, H. 2014. Fishing bait worm supplies in Japan in relation to their physiological traits. Memoirs of Museum Victoria 71: 279-287.Market research was conducted from 2009 to 2013 to investigate the supply of live worms for fishing bait in Japan. We obtained 25 types of live fishing bait worms, including 16 species of polychaete, 1 species of echiuran, and 1 species of sipunculid. These were divided into three groups according to their country of origin: 1) worms supplied from native populations, five species (Perinereis wilsoni, Hediste diadroma, Kinbergonuphis enoshimaensis, Pseudopotamilla occelata, and Hydroides ezoensis), 2) worms supplied from both native and non-native populations, three species (Marphysa cf. iwamushi, Halla okudai, and Urechis unicinctus), and 3) worms supplied from non-native populations, 10 species (Perinereis linea, Alitta virens, Nectoneanthes uchiwa, Namalycastis rhodochorde, Glycera nicobarica, Diopatra sugokai, Marphysa cf. tamurai, Marphysa cf. mossambica, Scoletoma heteropoda, and Sipunculus nudus). Salinities in which no mortality of nereid worms occurred was 5-35 psu in Alitta virens, 5-30 psu in Namalycastis rhodochorde, and 10-35 psu in Perinereis linea. Worms living in temperate areas had a wide temperature tolerance of 5-30 °C in Alitta virens, Perinereis linea, Glycera nicobarica, Marphysa cf. iwamushi, and Scoletoma heteropoda. Tropical species (Namalycastis rhodochorde and Marphysa cf. mossambica) could not survive above 20 °C.

“…The species has also been recently recorded in the Aegean and Levantine coasts of Turkey [118], but is currently unknown to any other location from the Meditterranean. Berke et al [116] considered the presence of D. marocensis in the Iberian Peninsula as the result of a human-mediated introduction, probably through the fishing bait trade, since harvesting and selling Diopatra species as a bait is a common resource in Atlantic areas of the Iberian Peninsula [119]. Berke et al [116] based their statement in the tube brooding of the larvae and the lack of planktonic stages that might facilitate dispersal between locations several hundred kilometers away, rendering all the Iberian populations as virtually isolated as long as only natural means of transport are involved.…”

This study provides an updated catalogue of non-indigenous species (NIS) of polychaetes reported from the continental coasts of the Iberian Peninsula based on the available literature. A list of 23 introduced species were regarded as established and other 11 were reported as casual, with 11 established and nine casual NIS in the Atlantic coast of the studied area and 14 established species and seven casual ones in the Mediterranean side. The most frequent way of transport was shipping (ballast water or hull fouling), which according to literature likely accounted for the introductions of 14 established species and for the presence of another casual one. To a much lesser extent aquaculture (three established and two casual species) and bait importation (one established species) were also recorded, but for a large number of species the translocation pathway was unknown. About 25% of the reported NIS originated in the Warm Western Atlantic region, followed by the Tropical Indo West-Pacific region (18%) and the Warm Eastern Atlantic (12%). In the Mediterranean coast of the Iberian Peninsula, nearly all the reported NIS originated from warm or tropical regions, but less than half of the species recorded from the Atlantic side were native of these areas. The effects of these introductions in native marine fauna are largely unknown, except for one species (Ficopomatus enigmaticus) which was reported to cause serious environmental impacts. In other cases, the displacement of native species or economic damages are suspected.

“…These organisms are both important predators and key disturbers of sediments. Their foraging activities create a landscape of pits that is only equaled on the eastern Atlantic by human activities such as organized bait digging along the Portuguese coast (Cunha et al 2005). Differences across the Atlantic extend to large infaunal bioturbators; these are composed almost entirely of arenicolid polychaetes in the East, but are joined by hemichordates in the West.…”

Abstract. The contrasting histories of the western and eastern shores of the North Atlantic Ocean provide an excellent opportunity to consider the implications of past events for present ecological processes and the functioning of marine ecosystems. Similarities and differences in assemblage composition have been driven by large-scale events, such as the trans-Arctic interchange, which has shaped the species pool, and cycles of glaciation, which have determined phases of local or regional extinction and colonization. More recently, anthropogenically induced invasions and local extinctions have significantly altered biogeographic distributions. Here we consider for both hard and soft substrata how the presence or absence of key taxa influences the outcomes of trophic and other biological interactions, and evaluate the consequences for community structure and ecosystem functioning. On intertidal hard substratum shores, biodiversity of epilithic microphagous grazers differs across latitudinal and longitudinal scales. Diversity is high in southern Europe but declines to the north and across the Atlantic. Lower diversity and the absence of patellid limpets in Iceland and the northwest Atlantic compared to Europe result in differences in consumer pressure, and an apparent contrast in the importance of herbivory vs. competitive interactions and predation pressure as community structuring processes. Interestingly, despite differences in ''process,'' community patterns are remarkably similar between the east and west. On soft sediment shores, there are conspicuous geographic differences in importance of bioturbators and large digging predators. Hemichordates can be abundant and important infaunal bioturbators in the western Atlantic, but they generally play a much reduced role in the eastern Atlantic. In addition, the number and diversity of digging predators on western Atlantic shores is high; the horseshoe crab, swimming portunid crabs, large whelks, excavating waterfowl, and an abundance of skates and rays exert intense predation pressure and associated biogenic disturbance to sediments. In Europe, except for excavating waterfowl these taxa are rare or absent. Thus, the importance of large, biological agents of disturbance is lower on European shores as a consequence of both recent anthropogenic pressure and natural processes over larger time scales. Consideration of key structuring taxa over the Atlantic shows that human-mediated transport has had considerable influence. Faunas on both sides of the Atlantic are becoming more similar to the point that some of the key differences in assemblage composition and hence community organization have blurred. Recent introductions as well as planned experimental manipulations provide the opportunity to understand the role of species identity in determining community structure and ecosystem functioning over large spatial scales; the North Atlantic may be an ideal test system to explore these areas.
