Abstract

This study aimed to analyze the distribution, endemism-conservation status, habitat features of inland water fish species and some threats in Düzce inland water systems. Fish samples were collected using electrofishing equipment, gill nets, fyke nets, and cast nets between April-October 2016. We have identified 17 fish taxa belonging to 9 families (Salmonidae (1 taxa), Acheilognothidae (1 taxa), Cyprinidae (2 taxa), Gobionidae (1 taxa), Leuciscidae (7 taxa), Tincidae (1 taxa), Cobitidae (1 taxa), Percidae (1 taxa), Gobiidae (2 taxa)). As a result of field observations conducted in Düzce province inland water, we determined 4 endemic (Gobio baliki, Squalius pursakensis, Alburnoides coskuncelebii and Cobitis splendens) and 2 invasive species (Carassius gibelio, Oncorhynchus mykiss). Endemic species were observed in narrow areas and small populations. Fish fauna and habitats were observed to be under the influence of drying, water and sand extraction, dam and pond building, pollution, mining and invasive species pressure.

Özet

Bu çalışma Nisan-Ekim 2016 tarihleri arasında Düzce içsu sistemlerinde dağılım gösteren iç su balık türlerinin, endemizm-korunma durumu, habitat özellikleri ve bazı tehditlerini analiz etmeyi amaçlamıştır. Balık örnekleri, elektroşoker, solungaç ağları, ığrıp ve pinter ağları kullanılarak toplanmıştır. Çalışmada 9 familyaya ait 17 balık taksonu (Salmonidae (1 takson), Acheilognothidae (1 takson), Cyprinidae (2 takson), Gobionidae (1 takson), Leuciscidae (7 takson), Tincidae (1 takson), Cobitidae (1 takson), Percidae (1 takson), Gobiidae (2 takson)).tespit edilmiştir. Düzce ilindeki iç sularda yapılan saha gözlemleri sonucunda, 4 endemik (Gobio baliki, Squalius pursakensis, Alburnoides coskuncelebii ve Cobitis splendens) ve 2 istilacı tür (Carassius gibelio, Oncorhynchus mykiss) belirlenmiştir. Endemik türlerin, dar alanlarda ve küçük populasyonlar halinde bulundukları gözlenmiştir. Balık faunası ve habitatların; kuruma, su ve kum çekimi, baraj ve gölet yapımı, kirlilik, madencilik ve yabancı türlerin baskısının olumsuz etkisi altında olduğu gözlenmiştir.
