Possible threat for middle east inland water: an exotic and invasive species, Pterygoplichthys disjuntivus (weber, 1991) in asi river, Turkey (Pisces: Loricariidae)

Ortadoğu iç suları için muhtemel tehdit: Asi Nehri’nde egzotik ve işgalci bir tür Pterygoplichthys disjunctivus (Weber, 1991) (Pisces: Loricariidae). Pterygoplichthys disjunctivus bireyleri Güney Amerika kökenli olup, bu egzotik ve işgalci türü bireyleri Kuzey Amerika ve Uzakdoğu ülkelerine dağılmışlardır. Orta Doğu’da yer alan Asi Nehri’nin Türkiye sınırları dahilinde daha önce kayıtlarda bulunmayan bir P. disjunctivus bireyi yakalanmıştır. P. disjunctivus Asi Nehri’nde potansiyel olarak işgalci bir tür olabilir. Eğer bu türün bireyleri Asi Nehri’ne yayılırsa, buradaki türlerden Garra rufa üyeleri muhtemelen ilk etkilenen doğal türlerden olacaktır. Çünkü P. disjunctivus ile aynı trofik düzeyde yer almaktadırlar.

Pterygoplichthys disjunctivus is native to South America and this exotic and invasive species has also been introduced accidentally into North America and the Far East. A P. disjunctivus specimen was found in Asi River, Turkey, which is in the Middle East, despite the fact that this species has not been observed in the region before. P. disjunctivus is a potentially invasive species of Asi River. It is assumed that if other members of this species were to spread into Asi River, Garra rufa members would most probably be the primarily impacted species because they are at the same trophic level as P. disjunctivus.
