ABSTRACT
Pseudorasbora parva (Temminck and Schlegel, 1842) has a significant potential to spread outside of its current locations and regions, all-continents-spanning invasive range. The invasion of P. parva has threatened the existence of native species. Therefore, evaluation of the condition and fitness of the invasive P. parva population in different regions is necessary. However, no systematic reports of the P. parva length-weight relationships (LWRs) around the world has been documented, especially comparing indigenous and non-indigenous populations. Thus, the goal of the current study was to offer a systematic report of P. parva LWRs worldwide and a comparison of P. parva LWRs in native and non-native regions. In the present results, P. parva showed positive-allometric growth, it became more rounded as the length increases, and both native and invasive populations showed similar growth patterns and form factor. Considering its invasive potential, the harmful effects of this alien species cannot be ignored. The present research will also focus on eliminating or mitigating the adverse effects caused by the further expansion of the species through a series of prevention and management strategies proposed.
