(2012) Isolation and inheritance of microsatellite loci for the oily bittering (Acheilognathuskoreensis): applications for analysis of genetic diversity of wild populations, Animal Cells and Systems, 16:4, 321-328, DOI: 10.1080/19768354.2011 The oily bittering Acheilognathus koreensis is a freshwater species that is endemic to Korea and is experiencing severe declines in natural populations as a result of habitat fragmentation and water pollution. For the conservation and restoration of this species, it is necessary to assess its genetic diversity at the population level. We developed 13 polymorphic microsatellite loci that were used to analyze the genetic diversity of two populations collected from the Kum River and the Tamjin River in Korea. All loci exhibited Mendelian inheritance patterns when examined in controlled crosses. Both populations revealed high levels of variability, with the number of alleles ranging from 3 to 20 and observed and expected heterozygosities ranging from 0.500 to 0.969 and from 0.529 to 0.938, respectively. None of the loci showed significant deviation from HardyÁWeinberg equilibrium, and one pair of loci showed significant linkage disequilibrium after Bonferroni correction. Pairwise F ST and genetic distance estimation showed significant differences between two populations. These results suggest that the microsatellites developed herein can be used to study the genetic diversity, population structure and conservation measure of A. koreensis.

“…It is necessary to conduct regular monitoring to protect and manage this species due to habitat development, climate change, and competition with invasive spe-cies. While research has been conducted on the morphology (Kawai and Min 2005), life history (Jung et al 2009;Ko and Kawai 2001), genetics (Ahn et al 2011;Kim et al 2012), and parasites (Song et al 2017) associated with C. similis, comprehensive studies on its ecological characteristics related to its physical habitat have not been reported yet.…”

Background: Cambaroides similis is an endangered candidate species living in the stream of South Korea. Freshwater crayfish is known to decline rapidly not only domestically, but also internationally. Its decline is projected to be further exacerbated due to climate change. Understanding physical characteristics of the habitat is crucial for the conservation of an organism. However, comprehensive data regarding the distribution and physical habitat characteristics of C. similis are currently unavailable in South Korea. Thus, the objective of this study was to ascertain preferred ranges for water depth, current velocity, and streambed substrate of C. similis using Weibull model. Results: In this study, C. similis was found at 59 sites across 12 regions in South Korea. Its optimal water depth preferences ranged from 11.9 cm to 30.1 cm. Its current velocity preferences ranged from 9.8 cm s -1 to 29.1 cm s -1 . Its substrate preferences ranged from -5.1 Φ m to -2.5 Φ m . Median values of central tendency were determined as follows: water depth of 21.4 cm, current velocity of 21.2 cm s -1 , and substrate of -4.1 Φ m . Mean values of central tendency were determined as follows: water depth of 21.8 cm, current velocity of 22.0 cm s -1 , and substrate of -4.4 Φ m . Mode values of central tendency were determined as follows: water depth of 21.7 cm, current velocity of 20.1 cm s -1 , and substrate of -3.7 Φ m . Conclusions: Based on habitat suitability analysis, physical microhabitat characteristics of C. similis within a stream were identified as Run section with coarse particle substrate, low water depth, and slow current velocity. Due to high sensitivity of these habitats to environmental changes, prioritized selection and assessment of threats should be carried out as a primary step.

“…A significant heterozygote deficiency was observed in the studied population. And also, Ahn et al (2011) studied population analysis of Cambaroides similis in Korea and developed and identified 8 microsatellite locus from 49 sample in 4 location (one population from Mt. Bukhan (BH), 3 of from Mt.…”

Crayfish are one of many freshwater organisms that are subject to biodiversity changes. The crayfish stocks in the world and Turkey have been damaged due to the crayfish plaque caused by Aphanomyces astaci, overfishing water pollution and other causes. For the continuation of endangered stocks of these species, it is necessary to protect the populations and restocking into apropriate environment. Environmental factors have an vital role in the genetic structure of a population. So the genetic diversity between population is vital because the information of the genetic construction of population is curical due to the ensuring sustainability and conservation of these species when evaluated with other factors but, unfortunately, still restricted. With this review, the genetic study conducted so far will be discussed to try getting important information for preservation and management of crayfish, because preservation of genetic diversity is very important for survival or persistence of these species such a long time.Keywords: Genetic diversity, fisheries, protection, biodiversity, molecular identification REVIEW Received Kerevitlerde Genetik Şifre Belirlemenin Önemi ve Kullanılan YöntemlerÖz: Kerevitler biyoçeşitlilik değişimlerine maruz kalan birçok tatlı su organizmalarından biridir. Dünyada ve Türkiye'de kerevit stokları Aphanomyces astaci fungusunun neden olduğu hastalık, aşırı avcılık, su kirliliği ve diğer nedenlerden tükenme tehlikesiyle karşı karşıya kalmıştır. Stokları tehlikede olan bu canlıların devamı için populasyonların korunması ve uygun çevrelere yeniden stoklanması gerekmektedir. Çevresel faktörler bir populasyonun genetik kompozisyonunda çok önemli rol oynar. Bu yüzden populasyonlar arasındaki genetik çeşitlilik büyük öneme sahiptir çünkü populasyonların genetik yapılarının bilinmesi bu türün devamının sağlanması ve korunması açısından hayatidir fakat ne yazıkki bu konuda yapılan çalışmalar hala sınırlıdır. Bu derlemeyle şimdiye kadar yapılan genetik çalışmalar tartışılarak kerevitlerin korunması ve yönetimi için önemli bilgiler elde edilmeye çalışılacaktır çünkü genetik çeşitliliğin korunması bu türlerin uzun süre yaşaması ya da varlığını sürdürmesi için çok önemlidir.
