Özet

Fish populations in smaller aquatic environments are affected by the fishing pressure at amuch faster pace. Often, compensation of this effect either takes a long time or is notpossible at all. For the purposes of establishing fishing regulations in these waterenvironments, the removal method is able to provide results quickly and almost accurately.The Lake Hazar, which is the environment of our study, is 8,600 hectares in size, and is anatural lake where Capoeta umbla species is caught commercially using gill nets. In thisstudy, stock size of Capoeta umbla in the Lake Hazar (Elazig) was estimated usingremoval method. In addition, the power of fishing and the status of fishing yield in the lakewere evaluated. In our research, it was determined that seven commercial fishing boatscaught 25,721 kg of fish in the lake in a fishing season. CPUE was calculated as 1.55 kg(kg/day/a gill net). As a result of the regression analysis, the amount of stock in the lakewas the estimated to be 37,781 kg (± 14,001 kg). When cumulative catch was formulatedas recommended by Ricker (1975), the population size was estimated to be 38,649 kg (±15,007 kg). As a result of our study, the use of removal method was found to beappropriate for small reservoirs with reduced population density due to strong fishingpressure.
