Abstract

Freshwater crayfish species, Astacus astacus (Europe), Astacus leptodactylus (Turkey, Europe) and Pasifastacus leniusculus(North America and Europea) are species with high commercial price that belong to the family Astacidea. Astacid culture is mainly based on semi-extensive systems in which stage II juveniles are stocked in natural earth ponds or in artifical ponds. Stocking into natural waters of produced juveniles in crayfish farming plays a significant role in the active protection of native species. The purpose of this review is development of the possibilities for crayfish farming by investigating most important factors affecting on survival rate and growth of juveniles in crayfish farming (cannibalism, stocking density, the number of shelters, nutrition, water temperature and photoperiod).

Özet

Astacus astacus (Avrupa), Astacus leptodactylus (Türkiye,Avrupa) ve Pasifastacus leniusculus (Kuzey Amerika ve Avrupa), Astacidae familyasına ait ticari değeri yüksek tatlı su ıstakozu türleridir. Bu türlerin yetiştiriciliğinde yavru üretimi daha çok II. dönem yavru kerevitlerin doğal toprak havuzlarda ya da yapay havuzlarda stoklanması şeklinde yarı ekstensif sistemlere dayalı olarak yapılmaktadır. Tatlı su ıstakozu yetiştiriciliği ile elde edilen yavruların doğal sulara stoklanması, doğal türlerin aktif olarak korunmasında önemli bir rol oynar. Bu derlemenin amacı, tatlı su ıstakozu yetiştiriciliğinde, yavruların hayatta kalma oranları ve gelişimleri üzerinde etkili olan en önemli faktörler (kanibalizm, stok yoğunluğu, barınak sayısı, beslenme, su sıcaklığı, fotoperiyot ) incelenerek, Astacidae familyası üyesi tatlı su istakozlarının yetiştiricilik olanaklarının geliştirilmesidir.
