Strategies for Conservation and Restoration of Freshwater Fish Species in Korea
KOREAN JOURNAL OF ICHTHYOLOGY, Vol. 21 Supplement, 29-37, July 2009 Received : April 22, 2009 ISSN: 1225-8598 Revised : June 6, 2009 Accepted : June 20, 2009 Strategies for Conservation and Restoration of Freshwater Fish Species in Korea By Eon-Jong Kang*, In-Chul Bang1 and Hyun Yang2 Inland Aquaculture Research Center, National Fisheries Research and Development Institute, Busan 619-902, Korea 1Department of Marine Biotechnology, Soonchunhyang University, Asan 336-745, Korea 2Institute of Biodiversity Research, Jeonju 561-211, Korea ABSTRACT The tiny fragment of freshwater body is providing home for huge biodiversity and resour- ces for the existence of human. The competing demand for freshwater have been increased rapidly and it caused the declination of biodiversity in recent decades. Unlike the natural process of extinction in gradual progress, the current species extinction is accelerated by human activity. As a result many fish species are already extinct or alive only in captivity in the world and about fifty eight animal species are in endangered in Korea including eighteen freshwater species. Conservation of biodiversity is the pro- cess by which the prevention of loss or damage is attained, and is often associated with management of the natural environment. The practical action is classified into in-situ, or ex-situ depending on the location of the conservation effort. Recovery means the process by which the status of endangerment is improved to persist in the wild by re-introduction of species from ex-situ conservation population into nature or translocation of some population. However there are a lot of restrictions to complete it and successful results are known very rare in case. -

E-mail: [email protected] 3Corresponding author Abstract Rhodeus albomarginatus, new species, is described from the Lvjiang River, a tributary flowing into Poyang Lake of Yang- tze River basin, in Anhui Province, China. It is distinguished from all congeneric species by unique combination of char- acters: branched dorsal-fin rays 10; branched anal-fin rays 10–11; longest simple rays of dorsal and anal fins strong and stiff, distally segmented; pelvic fin rays i 6; longitudinal scale series 34–36; transverse scale series 11; pored scales 4–7; vertebrae 33–34; colour pattern of adult males (iris black, belly reddish-orange, central part of caudal fin red, dorsal and anal fins of males edged with white margin). Key words: Cyprinidae, Rhodeus albomarginatus, new species, Yangtze River, China Introduction Bitterling belong to the subfamily Acheilognathinae in Cyprinidae and include three genera, Acheilognathus, Rhodeus and Tanakia. The genus Rhodeus can be distinguished from the other two genera by having an incomplete lateral line, no barbels, and wing-like yolk sac projections in larvae (Arai & Akai, 1988). -

In this study, we evaluated the impact of environmental variables and microhabitat patch types on fish distribution in Yudeung Stream at 15 sites between early May and late June 2019. We used non-metric multidimensional scaling to examine the distribution patterns of fish in each site. Gnathopogon strigatus, Squalidus gracilis majimae, Zacco koreanus, and Zacco platypus were associated with riffle and boulder areas, whereas Iksookimia koreensis, Acheilognathus koreensis, Coreoleuciscus splendidus, Sarcocheilichthys nigripinnis morii, and Odontobutis interrupta were associated with large shallow areas. In contrast, Cyprinus carpio, Carassius auratus, Lepomis macrochirus, and Micropterus salmoides were found at downstream sites associated with large pool areas, sandy/clay-bottomed areas, and vegetated areas. On the basis of these results, we suggest that microhabitat patch types are important in determining the diversity and abundance of fish communities, since a mosaic of different microhabitats supports diverse fish species. As such, microhabitat patches are key components of freshwater stream ecosystem heterogeneity, and a suitable patch composition in stream construction or restoration schemes will support ecologically healthy food webs.

Evaluation of length–weight relations for 15 fish species (Actinopterygii) from the Seomjin River basin in South Korea. Acta Ichthyol. Piscat. 50 (2): 209–213. Abstract. This study demonstrates the estimation of length–weight relations (LWR) for freshwater fishes from the Seomjin River basin in South Korea. The LWR estimation is based on the 15 species representing Cyprinidae: Rhodeus uyekii (Mori, 1935), Rhodeus notatus Nichols, 1929, Tanakia koreensis (Kim et Kim, 1990), Acheilognathus rhombeus (Temminck et Schlegel, 1846), Pseudorasbora parva (Temminck et Schlegel, 1846), Coreoleuciscus aeruginos Song et Bang, 2015, Sarcocheilichthys nigripinnis (Günther, 1873), Squalidus gracilis majimae (Jordan et Hubbs, 1925), Squalidus chankaensis tsuchigae (Jordan et Hubbs, 1925), Hemibarbus longirostris (Regan, 1908), and Opsariichthys uncirostris (Temminck et Schlegel, 1846); Cobitidae: Cobitis longicorpus Kim, Choi et Nalbant, 1976 and Cobitis tetralineata (Kim, Park et Nalbant, 1999); Bagridae: Tachysurus ussuriensis (Dybowski, 1872); and Amblycipidae: Liobagrus somjinensis Park et Kim, 2011. Our study provides new information of LWRs for eight species. The LWRs for those species have not been reported yet in FishBase. -
Evaluation of Reference Genes for RT-Qpcr Study in Abalone Haliotis Discus Hannai During Heavy Metal Overload Stress Sang Yoon Lee1 and Yoon Kwon Nam1,2*
Lee and Nam Fisheries and Aquatic Sciences (2016) 19:21 DOI 10.1186/s41240-016-0022-z RESEARCH ARTICLE Open Access Evaluation of reference genes for RT-qPCR study in abalone Haliotis discus hannai during heavy metal overload stress Sang Yoon Lee1 and Yoon Kwon Nam1,2* Abstract Background: The evaluation of suitable reference genes as normalization controls is a prerequisite requirement for launching quantitative reverse transcription-PCR (RT-qPCR)-based expression study. In order to select the stable reference genes in abalone Haliotis discus hannai tissues (gill and hepatopancreas) under heavy metal exposure conditions (Cu, Zn, and Cd), 12 potential candidate housekeeping genes were subjected to expression stability based on the comprehensive ranking while integrating four different statistical algorithms (geNorm, NormFinder, BestKeeper, and ΔCT method). Results: Expression stability in the gill subset was determined as RPL7 > RPL8 > ACTB > RPL3 > PPIB > RPL7A > EF1A > RPL4 > GAPDH > RPL5 > UBE2 > B-TU. On the other hand, the ranking in the subset for hepatopancreas was RPL7 > RPL3 > RPL8 > ACTB > RPL4 > EF1A > RPL5 > RPL7A > B-TU > UBE2 > PPIB > GAPDH. The pairwise variation assessed by the geNorm program indicates that two reference genes could be sufficient for accurate normalization in both gill and hepatopancreas subsets. Overall, both gill and hepatopancreas subsets recommended ribosomal protein genes (particularly RPL7) as stable references, whereas traditional housekeepers such as β-tubulin (B-TU) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) genes were ranked as unstable genes. The validation of reference gene selection was confirmed with the quantitative assay of MT transcripts. Conclusions: The present analysis showed the importance of validating reference genes with multiple algorithmic approaches to select genes that are truly stable. -

Accurate inferences of sister group relationships provide the researcher with an historical framework within which the attributes or geographic origin of species (or supraspecific groups) evolved. Taken out of this phylogenetic context, interpretations of evolutionary processes or origins, geographic distributions, or speciation rates and mechanisms, are subject to nothing less than a biological experiment without controls. -

E-mail: [email protected] Abstract Coreoleuciscus splendidus was first reported as a monotypic species. Recent morphological and genetic studies have re- vealed that the species is represented by two disjunct and distinct lineages. The two lineages of C. splendidus include pop- ulations inhabiting the Han and Geum rivers in the East Korea Subdistrict and populations inhabiting the Seomjin and Nakdong rivers in the South Korea Subdistrict. In this study, significant differences were found between these two inde- pendent lineages through a high degree of genetic divergence in the mitochondrial cytochrome c oxidase subunit I gene as well as conspicuous morphological differences in body coloration and shapes of black stripes on dorsal, anal and caudal fin rays. These morphological and genetic differences provide supporting evidence that the populations in the South Korea Subdistrict represent a new species, Coreoleuciscus aeruginos. Key words: Coreoleuciscus aeruginos, Coreoleuciscus splendidus, Korea, new species Introduction There are 33 species from 17 genera in the subfamily Gobioninae in Korea. The genus Coreoleuciscus consists of a monotypic species (Mori, 1935; Kim et al. 2005), the Korean shinner C. -
