The “Tsunami Break:” Impact of the Great East Japan Earthquake and the Accompanying Tsunamis on the Shell Growth of the Invasive Clam‑Eating Snail Laguncula Pulchella
Fisheries Science (2018) 84:485–494 https://doi.org/10.1007/s12562-018-1197-2 ORIGINAL ARTICLE Biology The “tsunami break:” impact of the Great East Japan Earthquake and the accompanying tsunamis on the shell growth of the invasive clam‑eating snail Laguncula pulchella Masahiro Suzuki1 · Kenji Okoshi1 Received: 26 October 2017 / Accepted: 6 March 2018 / Published online: 21 March 2018 © The Author(s) 2018 Abstract The Great East Japan Earthquake and accompanying tsunamis occurred on 11 March 2011, causing huge damage to marine organisms. The invasive naticid gastropod Laguncula pulchella (Euspira fortunei), which was introduced with the imported clam Ruditapes philippinarum from China and Korea, survived the earthquake. The “growth break line” observed on the shell surface in over 90% of the individuals collected in Matsushima Bay and Matsukawa-ura Lagoon after the tsunamis was exam- ined by scanning electron microscopy. Each shell presented three layers before and three after the growth break. However, the fracture surface consisted of fve layers—two prismatic and three crossed lamellar—around the growth break line. This suggests that shell formation temporarily ceased following the tsunamis and that the fve-layered shell may have developed in response to the stress caused by the tsunamis. The newly formed middle layer became thinner after the “tsunami break,” which may be the result of a rapid change in the mineralization process, including rapid shell growth and/or repair. These results suggest that the damage to and forcible removal of habitats by the tsunamis was stressful for L. pulchella. A decrease in or the cessation of shell formation after a tsunami may be a common phenomenon in mollusks that inhabit tidal fats. -

Chen*†,J.B.K.Leonard‡ and H.

The results demonstrate the ability of O. keta to discriminate artificial stream waters containing natural levels of DFAA. © 2016 The Fisheries Society of the British Isles Key words: artificial stream waters; dissolved free amino acids; homing behaviour; PIT tag; Y-maze. INTRODUCTION The ability of Pacific salmonids to successfully return to their natal stream follow- ing outmigration to and rearing in the ocean is a critical component of the success of the group (Groot & Margolis, 1991; Dittman et al., 1996). -

Of these species, T. hakonensis is widely distributed in Japan and is important in commercial and recreational fisheries. Two species, T. hakonensis and T. brandtii, exhibit anadromy. In this paper, information on the protistan and metazoan parasites of the four species of Tribolodon in Japan is compiled based on the literature published for 106 years between 1908 and 2013, and the parasites, including 44 named species and those not identified to species level, are listed by higher taxon as follows: Ciliophora (2 named species), Myxozoa (1), Trematoda (18), Monogenea (0), Cestoda (3), Nematoda (9), Acanthocephala (2), Hirudinida (1), Mollusca (1), Branchiura (0), Copepoda (6 ), and Isopoda (1). For each taxon of parasite, the following information is given: its currently recognized scientific name, previous identification used for the parasite occurring in or on Tribolodon spp.; habitat (freshwater, brackish, or marine); site(s) of infection within or on the host; known geographical distribution in Japan; and the published source of each locality record. -

A Checklist and Bibliography of Parasites of Salmonids of Japan
;r c j . 3 $JJ#~,Sci. Rep. Hokkaido Salmon Hatchery, (41) : 1-75 (1987) A Checklist and Bibliography of Parasites of Salmonids of Japan Kazuya NAGASAWA*',Shigehiko URAWA", and Teruhiko AWAKURA*~ Abstract Information on the parasites of salmonids in Japanese waters that was published during the years 1889-1986 is assembled in the form of Parasite-Host and Host- Parasite lists with accompanying bibliography. Ninety-four named species of parasites (18 Protozoa, 5 Monogenea, 21 Trematoda, 7 Cestoidea, 19 Nematoda, 15 Acanthocephala, 1 Hirudinoidea, 1 Mollusca, 1 Branchiura, 5 Copepoda, 1 Isopoda) have been reported, and numerous other parasites not identified to species level are also included. The Parasite-Host list, arranged on a taxonomic basis, includes for each parasite species its currently recognized scientific name, and synonyms oc- curring in the literature, habitat (freshwater or marine), location of infection (site) within the host, species of host(s), known geographical distribution in Japanese waters, and the published source for each host and locality record. Where neces- sary, remarks and footnotes dealing with such topics as taxonomy, nomenclature, and misidentifications are included. The Host-Parasite list summarizes the species of parasites from each species of salmonid and their geographical distributions. Although taxonomic revision is not the aim of the checklist, the following three new combinations and one new synonym are proposed : Microsporidium takedai (Awa- kura, 1974) n. comb. for Nosemu tukedui ; Sterliudochonu ephemeridurum (Linstow, 1872) n. comb. for Cystidicoloides ephemeridurum ; and Salvelinema ishii (Fujita, 1941) new synonym of S. salvelini (Fujita, 1939) n. comb. for Metabronemu salvelini.

In southern Japan, few records of L. pulchella exist; furthermore, the knowledge concerning the ecology of this organism is cur- rently limited. Unexpectedly, we found many L. pulchella individuals in the Misuji River estuary, located in Hiroshima in southern Japan, during May 2015. We conducted a field survey on the density and body size of L. pulchella at a tidal flat in the Misuji River estuary (Site H) and compared those to L. pulchella in Matsukawaura Lagoon, located in Fukushima in northern Japan (Site F). The adult population of L. pulchella in a clam fishing ground (40,500 m2) at Site H was estimated to be 2,048 individuals in 2015. Densities of both surfaced individuals and egg collars of L. pulchella were lower at Site H than at Site F. Sizes of L. pulchella individuals and their egg collars as well as the somatic weight of the individuals at Site H were significantly smaller than those at Site F. -

Since the end of 19th century it has been introduced in all other continents. For the present survey most of the known self-sustaining brown trout river populations in Japan have been sampled and analyzed through sequences of the entire mitochondrial DNA control region and twelve microsatellites. In Japan, brown trout are genetically not homogeneous, probably as a consequence of several introductions, one in the Azusa river and at least one other in the remaining territory. The Chuzenji hatchery houses a genetically very distinct strain, probably due to intense manipulation in isolated scientific experimentations over 30 years. Finally, most populations showed high genetic diversity (Mamachi, Kane and Odori streams, Lake Chuzenji) with the exception of the Azusa river samples.
