Genetic diversity, effective population size, and population structure of mandarin fish (Siniperca scherzeri) in Korea: Implications for broodstock management and hatchery seed production

Kang-Rae Kim, Yeong Ho Kwak, Keun-Young Kim, JeeHyo Song et autres

Genetic evaluation of hatchery resources is essential for the stable production of high-quality seed in freshwater aquaculture, particularly in species for which artificial propagation and release are being developed or expanded. In this study, we assessed the genetic diversity, effective population size, …

Population Genetic Structure and Reduced Diversity in Upstream Populations of the Endangered Nakdong Nose Loach ( Koreocobitis naktongensis ) Revealed by Novel Microsatellite Markers

Keun-Sik Kim, Kang-Rae Kim, Sang‐Yong Park, Ju‐Duk Yoon et autres

ABSTRACT We developed and validated seven polymorphic microsatellite loci for the endangered Nakdong nose loach ( Koreocobitis naktongensis ) and used them to assess genetic diversity and population structure across the Nakdong River basin in the Republic of Korea. The loci showed …

Characterization of Three Complete Mitochondrial Genomes of Hemiculter and Comparative Mitogenomic Analysis of Cultrinae Fishes

Seung Hyun Lee, Sang Ki Kim, Seung Woo Jang, Kyong In Suh et autres

The genus Hemiculter includes closely related freshwater fishes widely distributed across East Asia, and several species are difficult to distinguish using external morphology alone. Mitochondrial markers have been widely used for species identification and phylogenetic inference in fishes, but single-gene approaches may …

A Multiplex PCR-Based Assay for Authentication of Six Commercially Important Cephalopod Species

Kang-Rae Kim, Hye Jin Kim, Seong-Jin Park, In-Chul Bang

Cephalopod products are widely distributed as frozen raw materials or cut portions, making morphology-based species identification difficult during commercial handling and inspection. In this study, we developed a conventional multiplex PCR assay for the simultaneous identification of six commercially important cephalopod species, …

Optimization of MS-222 Concentration for Short-Term Handling of Juvenile Pseudopungtungia nigra Based on Induction and Recovery Responses

Kang-Rae Kim, In-Chul Bang

The black shinner Pseudopungtungia nigra is an endangered freshwater fish endemic to Korea, and standardized anesthetic protocols are needed for conservation-related hatchery handling. This study evaluated the effects of water temperature and MS-222 concentration on anesthetic induction and recovery responses in hatchery-reared …

Population Genetic Structure and Regional Divergence of the Endangered Freshwater Fish Black Shinner Pseudopungtungia nigra Based on Mitochondrial DNA

Kang-Rae Kim, In-Chul Bang

Assessing genetic structure is important for conserving endangered freshwater fishes inhabiting fragmented river systems. Pseudopungtungia nigra, a Korean endemic species, occurs in several isolated drainages, but its mitochondrial population structure has not been fully evaluated. In this study, we analyzed mitochondrial cytochrome …

Long-term changes in the genetic diversity of the endangered freshwater fish Microphysogobio koreensis (Gobioninae) in Korea

Kang-Rae Kim, Keun-Sik Kim, Hyun Yang, Ju‐Duk Yoon et autres

BACKGROUND: Microphysogobio koreensis is an endangered freshwater fish endemic to the Nakdong and Seomjin River systems in Korea. Because its distribution is restricted and population decline has been reported, genetic monitoring is needed to evaluate temporal changes in diversity and to define …

Genetic Variation and Spatial Genetic Structure of Eleocharis ussuriensis Zinserl. in South Korea: Implications for Ecological Monitoring and Resource Management

Eunhye Kim, Kang-Rae Kim, Mi-Hwa Lee, Jaeduk Goh et autres

Background/Objectives: Eleocharis ussuriensis Zinserl. is a perennial riparian sedge widely distributed in Northeast Asia and a dominant component of freshwater vegetation in South Korea. However, the intraspecific genetic structure of this species across contrasting hydrological habitats remains insufficiently understood. This study aimed …
