Length-Weight Relationships and Condition Factors of Eight Exotic Fish Species from Turkey

Öz

Length-weight relationships (L-WRs) and condition factors were estimated for eight exotic fish species, including Oreochromis niloticus, Coptodon zillii, Carassius auratus, C. gibelio, Pseudorasbora parva, Gambusia holbrooki, Lepomis gibbosus, and Oncorhynchus mykiss from 10 basins of Turkish inland waters. A total of 1958 specimens were sampled in the years of 2014, 2017, 2018, and 2019 from 29 populations and their LWRs parameters, and form, Fulton’s, relative and mean condition factors were estimated. The estimated values of the parameter b ranged from 2.732 (C. auratus) to 3.319 (C. gibelio) with the mean and median values estimated at 3.013 and 3.047, respectively. The R2 values varied from 0.753 to 0.998, indicating a high degree of positive relationship between length and weight. The Fulton’s condition factor was estimated as 0.882 for P. parva and 2.002 for L. gibbosus. with the mean and median values of 1.397 and 1.453, respectively. This situation reveals that the condition values of all alien species except P. parva are quite high. In addition, the condition factor values of exotic fish species and local species they live with in Çıldır Lake were compared. As a result of this comparison, it was determined that C. gibelio had the highest condition factor value.
