“…In order to assess the morphological changes of this invasive species, researches were conducted in the Aegean and Thracian regions. Here, body shape variability in sampling populations of L. gibbosus showed significant geographical and environmental differences with and without allometric standardization, it indicates that depending on the morphometric research hypothesis, species may be important implementation of allometric regression and standardization (Mangit et al, 2018;Reis et al, 2018 ).…”

Researches of fluctuating asymmetry of the bilateral features of fish were conducted in 2018 on the natural reservoirs (the Samara River within Novomoskovsk and Pavlograd districts of Dnipropetrovsk region, the reservoirs of the Dnipro-Oril Nature Reserve). Insignificant deviations from the bilateral symmetry of external features in living organisms may indicate a decrease in the vitality of certain populations. Using of mass, widespread fish species as the test objects is the best way to detect the levels of fluctuating asymmetry. The fluctuating asymmetry of four bilateral features was estimated within 146 units of the common sunfish Lepomis gibbosus, the stone moroco of Pseudorasbora parva and the round goby Neogobius melanostomus in different habitat conditions, the stability of their life circle was evaluated. The number of rays in the interbranchial septum, the number of branching rays in the pectoral and abdominal fins, the number of scales in the lateral line were analysed. The variability of these features on the left and right sides of the fish was evaluated. The lowering of the natural fish populations vitality because of the influence of negative anthropogenic pressure is currently minor. The stability of fish development by the analysis of bilateral features is noted within normal limits of 1 point (Neogobius melanostomus from the reservoirs of the Dnipro-Oril Nature Reserve, Lepomis gibbosus and Pseudorasbora parva from the middle section of the Samara River) or deviates insignificantly from the statutory indicator in 2 points (Lepomis gibbosus from the lower section of the Samara River). Species of Neogobius melanostomus from the reservoirs of the Dnipro-Oril Nature Reserve show the lowest quantitative indices of the bilateral features asymmetry (0.17 of asymmetric detections per feature). This may demonstrate the absence of negative anthropogenic impact on ground fish within the particularly guarded water areas. The application of the analysis of the fluctuating fish asymmetry is the simplest and most accessible way of rapid testing of the water environment state, but complex laboratory studies, including molecular and biochemical ones, must be used to obtain a more accurate and reliable estimate.

“…At this stage, adaptive plasticity (phenotypic plasticity) can increase invasion success by producing favorable traits acquired through directional selection by each subsequent generation ( Yavno and Fox, 2013 ). Phenotypic plasticity based on morphology is quite common in invasive species ( Záhorská et al, 2009 , Cerwenka et al, 2014 , Mangit et al, 2018 ). Thus, external morphometry is one of the most accessible ways to assess how species cope with environmental plasticity.…”

“…Pumpkinseed inhabits both lentic and lotic environments and most studies have been conducted in Europe (Copp et al, 2002; Villeneuve et al, 2005; Fox et al, 2011; Vilizzi et al, 2012). Investigations of populations in Turkey have focused on their dispersal (Özcan, 2007; Reis et al, 2018), colonisation success (Ağdamar et al, 2015), habitat use (Top et al, 2016) and morphological variation (Mangıt et al, 2018). Albeit the increasing expansion of L .…”

The survival and establishment of alien fishes in novel environments can result in resource partitioning with native fishes. This can cause ecological impact and suppression of native populations. However, quantifying the impact of novel interactions between alien and native species remains highly challenging in the wild. Consequently, to determine the ecological risk of Lepomis gibbosus in case of introduction to a small stream, experimental approach was used to predict its competitive interaction with a poorly studied endemic fish, Capoeta aydinensis. The aim was to test whether L. gibbosus has an adverse effect on native species using an experimental design under allopatric and sympatric context with temperature regimes of 15 and 24ºC. The results indicated that temperature and fish proportion had effects on the growth of C. aydinensis while these factors were not important for L. gibbosus. These results provided little evidence of L. gibbosus presence being detrimental for endemic C. aydinensis, but nevertheless steps should be taken to avoid their further co‐habitation in the wild.
