In this study, length-weight relationship (LWR), length- length relationship (LLR) and condition factor (K) of Angora loach, Oxynoemacheilus angorae were determined. A total of 103 specimens were sampled from Kılıçözü Stream in 2014. The length and weight of specimens were ranged 3.5-9.8 cm and 0.38-6.58 g, respectively. Length-weight relationships for female, male and all samples were found as W= 0.01056.TL2.896 (r²= 0.923), W= 0.00963.TL2.940 (r²= 0.978) and W= 0.00987.TL2.929 (r²= 0.963), respectively. LWRs indicated an isometric growth in female, male and all samples. The values of Fulton’s condition factor (K) ranged from 0.699 to 1.246 for females and from 0.654 to 1.072 for males. All length-length relationships were statistically significant.

The increase in the diversity of needs arising from population growth, technological development and globalization causes more use of limited natural resources and brings with it consequences such as wear and pollution of resources. This study focused on the dam lakes on the Kızılırmak River in Türkiye, whose fisheries production rights were leased. There are İmranlı, Yamula, Bayramhacılı, Hirfanlı, Obruk, Boyabat and Derbent dam lakes on which the right to produce fishery products are leased on Kızılırmak, which is the longest river within the borders of Türkiye. Among these, the most rented region is in the Hirfanlı Dam Lake. Sustainability of fisheries in these dam lakes on Kızılırmak River is important in terms of meeting healthy protein demand and socio-economic development. Fishing, which has commercial value in these dam lakes, provides both employment and significant economic contribution to the people of the province and district where they are located. In order to benefit from this potential in a healthy way, it has been concluded that it is very important to operate these dam lakes in a balance of protection and use. However, it is necessary to increase the incentives and support of fishermen especially in these fishing regions.
