Abstract

Length-weight relationships (LWR) were estimated for 30 fish species i.e. Abbottina rivularis, Alburnus chalcoides, A. oblongus, A. taeniatus, Carassius gibelio, Channa argus, Cottus spinulosus, Cyprinus carpio, Gambusia holbrooki, Glyptosternon oschanini, Gobio lepidolaemus, Hemiculter leucisculus, Hypophthalmichthys nobilis, Iskandaria kuschakewitschi, Luciobarbus conocephalus, Micropercops cinctus, Opsariichthys bidens, Pelecus cultratus, Petroleuciscus squaliusculus, Pseudorasbora parva, Rhinogobius cf. lindbergi, Rhodeus ocellatus, Sabanejewia aralensis, Salmo oxianus, Schizothorax eurystomus, Triplophysa daryoae, T. elegans, T. ferganaensis, T. labiata, and T. strauchii from the Upper Syr Darya drainage, Uzbekistan. The LWR parameters were determined using a linear logarithmic regression model of weight against length in which values for the slope of the regression, b, that are higher and lower than 3 indicate positive and negative allometric growth, respectively. The estimated values of parameter b ranged from 2.719 (Cyprinus carpio) to 3.442 (Pelecus cultratus). The correlation coefficient (r2) values varied from 0.945 to 0.998, indicating a strong positive relationship between length and weight. This study establishes new maximum total lengths for three species (Glyptosternon oschanini, Gobio lepidolaemus, and Petroleuciscus squaliusculus) and presents LWRs for the first time for 17 fish species in the inland waters of Uzbekistan, including 7 previously unreported in FishBase.
