Six specimens (124.4–240.0 mm standard length) of a non-native cichlid fish, Coptodon zillii (Gervais, 1848), were collected from a small branch of the Okita River system, Nobeoka City, Miyazaki Prefecture, southern Japan. This species has already been known from Shiga, Oita, Kumamoto, Miyazaki, Kagoshima, and Okinawa prefectures as an introduced species to Japan. This paper provided description and color images of collected specimens with report of in situ behavioral observation. The present specimens and field-observation records implicate reproduction of C. zillii in the collection site.

A specimen of ambicolored Pseudorhombus cinnamoneus (Temminck and Schlegel, 1846) was collected off northern part of Miyazaki Prefecture, southern Japan. This specimen shows blown-based color with a black blotch surrounded by small yellowish-brown dots on ocular side. Although almost all P. cinnamoneus show pale color on whole blind side, the blind side of the present specimen shows almost same color pattern as ocular side. This phenomenon is called “ambicoloration”, commonly seen on various species of flatfishes and several past studies reported it in artificial seedling productions. The present specimen represents the first record of ambicoloration in a native specimen of P. cinnamoneus.

A single specimen (98.5 mm standard length) of the reticulate river pipefish, Hippichthys heptagonus Bleeker, 1849 (Gasterosteiformes, Syngnathidae) was collected from an estuary in Nobeoka City, Miyazaki Prefecture, eastern coast of Kyushu, southern Japan. Although this pipefish species had already been recorded from Nobeoka City, the previous record did not show any verifiable vouchers. Therefore, the present paper represents the first specimen-based record of H. heptagonus from the mainland of Kyushu.

The use of estuarine and marine ecosystems by amphidromous fishes has not been thoroughly studied, especially with respect to habitat types. Here, abundance and size comparisons of juveniles of an amphidromous fish, ayu (Plecoglossus altivelis altivelis), were performed among four types of topographically distinct shallow, soft-bottom habitats across two different environmental contexts (marine and estuarine) through monthly seining along an estuary–ocean ecotone in southern Japan. Topography (open/enclosed and presence/absence of surf zone) and environmental parameters (water temperature and salinity) differed among the four habitats, i.e., riverine estuary, exposed beach, embayed beach, and lagoon estuary. The peak month of juvenile abundance also differed among habitats (riverine estuary in December, exposed beach in January, embayed beach and lagoon estuary in March), as did the mean standard length (riverine estuary < exposed beach < embayed beach < lagoon estuary), although the abundance at embayed beach was significantly greater than in the two estuaries, and almost all size classes of juveniles occurred at embayed beach. A likely explanation for these patterns is that juvenile ayu select coastal habitats as they develop swimming ability and that riverine estuary/exposed beach, embayed beach, and lagoon estuary function as a corridor, primary nursery, and possible foraging ground, respectively. These findings, coupled with implications from previous studies of habitat selection in coasts by anadromous fishes, highlight the importance of seascape-level analysis for elucidating the nursery functions of coastal habitats, even for diadromous nekton.

© 2020, Academia Sinica. All rights reserved. Several temperate marine taxa of the northern hemisphere follow a trans-Pacific biogeographic track with representatives on either side of the intervening boreal waters. Shelter-dwelling blenniiform fishes of the genus Neoclinus exhibit this trans-Pacific distribution pattern with three species in the eastern North Pacific and eight species in the western North Pacific. We reconstructed the phylogeny of the Neocliniini (Neoclinus and the monotypic Mccoskerichthys) using six genetic markers: four mitochondrial genes (COI, cytochrome b, 12S and 16S), and two nuclear genes (RAG-1, TMO-4C4). Ancestral state reconstruction and molecular clock dating were used to explore hypothetical ancestral distributions and area relationships, and to estimate divergent times within this group. The monophyly of the genus Neoclinus, and the reciprocal monophyly of the eastern Pacific and western Pacific lineages were supported. Available evidence, including the eastern Pacific and western Atlantic occurrence of a New World clade of blennioid fishes that includes this lineage, supports the origin of the Neocliniini in the eastern Pacific with a single divergence event to the west across the North Pacific by the ancestor of the western Pacific clade. Estimated divergence time of the eastern and western Pacific clades of Neoclinus was 24.14 million year ago, which falls during the Oligocene epoch. Estimated times of divergence in other trans-Pacific lineages of marine fishes vary widely from recent Pleistocene events to as early as 34 mya.

© 2019, Springer Nature B.V. Large biodiversity datasets are currently being collected not only by experts and amateur researchers, but also by the general public. In this study, records of non-native and Japanese Red List fishes observed by citizens were extracted from all 85,453 posts on the bulletin board system of WEB sakana-zukan, a web-based encyclopedia of Japanese fishes that went online in 2002. We found 681 (0.8%) and 549 (0.6%) posts containing attached images of non-native and Red Data Book fishes, resulting in 418 and 362 Japanese distributional records respectively. The number of posts and the composition of non-native species reflected the Japanese inland fisheries policy to increase target species. These data included records of exotic species (eleven taxa) whose introduction to Japan had been unknown previously, as well as records of nine exotic/domestic species whose introductions into specific Japanese regions had been unknown. Additionally, we identified the range extension of one Red Data Book species. These photographs were stored in a public museum’s photographic collection for ongoing scientific use. Three heavy users of the website combined contributed 26.7% of the new distribution records (8/30 lots), while 15 light users contributed 50.0% (15/30 lots), suggesting that overall there is a greater contribution by light users. This indicates that a web community with abundant users can accumulate new biodiversity observations better than one with fewer users but many posts per user. Our results show that this web-community was able to contribute to monitoring non-native and Red List fishes in conjunction with expert participation, and therefore that web-communities targeting living organisms can contribute to biodiversity conservation.

Fish rubbings, ‘gyotaku’, as a source of historical biodiversity data 査読あり

記述言語：英語 掲載種別：研究論文（学術雑誌）
Methods for obtaining historical biodiversity information are mostly limited to examining museum specimens or surveying past literature. Such materials are sometimes time limited due to degradation, discarding, or other loss. The Japanese cultural art of ‘gyotaku’, which means “fish impression” or “fish rubbing” in English, captures accurate images of fish specimens, and has been used by recreational fishermen and artists since the Edo Period (the oldest known ‘gyotaku’ was made in 1839). ‘Gyotaku’ images often include distributional information, i.e., locality and sampling date. To determine the extent and usefulness of these data, field and questionnaire surveys targeting leisure fishing and boating stores were conducted in the following regions where threatened or extinct fishing targets exist (four regions including the northernmost to the southernmost regions). As a result, 261 ‘gyotaku’ rubbings were digitally copied with their owners’ consents. From these, distributional data were extracted for 218 individuals, which roughly represented regional fish faunas and common fishing targets. The peak number of ‘gyotaku’ stocked at the surveyed shops was made in 2002, while ones made before 1985 were much fewer. The number of ‘gyotaku’ rubbings made in recent years shows a recovery trend after 2011–2012. The present study demonstrates the validity of examining ‘gyotaku’ for historical biodiversity information.

Leiuranus versicolor (Richardson, 1848) is recorded based on a specimen from Miyazaki Prefecture, southern Japan. It represents the first Japanese and northernmost record. Leiuranus versicolor is similar to L. semicinctus, its single congener. The former can be easily separated from the latter by its unique banded pattern, usually with a narrow whitish yellow slit (vs. slit absent). The species was also photographed from Kashiwajima, southern part of Kochi Prefecture, southern Japan.

A single specimen of the engraulid fish Encrasicholina pseudoheteroloba (Hardenberg, 1933) (49.3 mm in standard length), a tropical Indo-West Pacific species, was collected as bycatch in one of two commercial set nets in Kadogawa Bay, northern Miyazaki Prefecture, Kyushu, Japan. Extending the northern distribution limit of E. pseudoheteroloba by about 530 km north-northeastward of the previous northernmost specimen-based record (Amami-oshima island, Satsunan Islands), the specimen represents the first verifiable temperate zone record of the species and first from mainland Japan. The temperate zone record is discussed and a description of the specimen given.
