Importance of Determining Genetic Code In Crayfish and Methods Used

Abstract

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.

Kerevitlerde Genetik Şifre Belirlemenin Önemi ve Kullanılan Yöntemler

Öz

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.
