Developing a Microsatellite Polymerase Chain Reaction System for Small Yellow Croaker () and Its Application in Parentage Assignment.

(1) Background: The small yellow croaker, an economically important fish in East Asia, has been subjected to population declines due to overfishing and environmental pressures. The development of effective breeding programs is considered crucial for the species, and accurate parentage assignment is deemed essential for such programs. (2) Methods: The assembled reference genome of the small yellow croaker was utilized to select highly polymorphic microsatellite markers.

SNP Array for Small-Shrimp (Genus ) Origin Determination Using Machine Learning.

Accurate origin determination of seafood is crucial for consumer trust and safety. This study was performed to develop a machine learning-based single-nucleotide polymorphism (SNP) analysis technique to determine the origin of species in salted small-shrimp products. Mitochondrial DNA (COI and 16S rRNA) analysis revealed genetic variations among species and origins.

Clinical Assessment of Thermotherapy Applications during Hepatectomy and Laparotomy in Sturgeon (): Impact on Bioparameter Variations Based on Liver Condition.

Surgical techniques are gaining attention for treating physical diseases in aquaculture and aquarium fish. Sturgeon is a suitable species for surgical experiments due to its industrial significance. Maintaining homeostasis is crucial during surgical procedures, and the liver plays a major role in immune regulation.

Identification of Potential Hazards Associated with South Korean Prawns and Monitoring Results Targeting Fishing Bait.

This study detected two potential pathogens, , which causes acute hepatopancreatic necrosis disease (AHPND), and white spot syndrome virus (WSSV), in fishing bait in South Korea. However, their infectious nature was not confirmed, possibly due to the degradation caused by freezing/thawing or prolonged storage under frozen conditions. While infectivity was not confirmed in this study, there is still a significant risk of exposure to these aquatic products.

Draft genome of the Korean smelt Hypomesus nipponensis and its transcriptomic responses to heat stress in the liver and muscle.

Pond smelt (Hypomesus nipponensis) is a cold-freshwater fish species and a winter economic aquaculture resource in South Korea. Because of its high susceptibility to abnormal water temperature from global warming, a large number of smelt die in hot summers. Here, we present the first draft genome of H.

Genotyping-by-Sequencing of the regional Pacific abalone (Haliotis discus) genomes reveals population structures and patterns of gene flow.

Continuous monitoring of the present genetic status is essential to preserve the genetic resource of wild populations. In this study, we sequenced regional Pacific abalone Haliotis discus samples from three different locations around the Korean peninsula to assess population structure, utilizing Genotyping-by-Sequencing (GBS) method. Using PstI enzyme for genome reduction, we demonstrated the resultant library represented the whole genome region with even spacing, and as a result 16,603 single nucleotide variants (SNVs) were produced.

Classification of Takifugu rubripes, T. chinensis and T. pseudommus by genotyping-by-sequencing.

Takifugu rubripes is more expensive than other species of the genus because of its high protein content and special flavor. However, it is easily confused with imported T. chinensis and T.

Quantitative analysis of Alaska pollock in seafood products by droplet digital PCR.

A highly accurate quantitative method, based on the new technique, droplet digital PCR (ddPCR), was applied to determine the content of Alaska pollock (Gadus chalcogrammus) in seafood products. Using this method, we found a linear relationship among raw sample weight, DNA concentration and DNA copy number. We also established a formula to calculate the raw sample weight, based on the number of DNA copies.

Rapid Origin Determination of the Northern Mauxia Shrimp (Acetes chinensis) Based on Allele Specific Polymerase Chain Reaction of Partial Mitochondrial 16S rRNA Gene.

Acetes chinensis is an economically important shrimp that belongs to the Sergestidae family; following fermentation, A. chinensis' economic value, however, is low in China, and much of the catch in China is exported to Korea at a low price, thus leading to potential false labeling. For this reason, we developed a simple method to identify A.

Isolation and characterization of novel microsatellite markers for the northern mauxia shrimp, Acetes chinensis, using pyrosequencing.

Among the 14 species in the Acetes genus, Acetes japonicus and Acetes chinensis, are the only and also abundant two species around the Korean Peninsula, and are used in traditional recipes. These species are of great economic importance, but little is known about their population genetics, despite the fact that information of this kind is important for stock assessment, fisheries management and identification of origin. A total of 9 microsatellite (MS) markers for A.
