“…The low contribution of variables related to Reproduction and Dispersal mechanisms (Table 1) is particularly interesting in the context of the current debate on the effect of reproductive strategy on invasion success. Clearly, there are species with very different reproductive modes amongst successful invaders, but both model predictions (Moyle and Marchetti, 2006;Lawson and Hill, 2021) and field data (Grabowska and Przybylski, 2015;Dashinov and Uzunova, 2021) indicate the potential benefit of certain reproductive strategies for non-native species' establishment in new habitats. In the case of Pterygoplichthys spp., one explanation for their successful worldwide spread may also be due to their reproductive traits, as suggested by some authors (da Silva, 2019).…”

The invasion risk of non-native suckermouth catfishes Pterygoplichthys spp. in the River Dinh (Vietnam) was evaluated using two related decision-support tools, namely the Fish Invasiveness Screening Kit (FISK) and the Aquatic Species Invasiveness Screening Kit (AS-ISK). The results of screenings obtained independently by three assessors using both toolkits were evaluated for consistency, and compared with a screening study previously obtained for Vietnam as a wide risk assessment area. Both FISK and AS-ISK based screenings were shown to provide adequate and potentially important outcomes in terms of risk of invasiveness and were consistent amongst assessors and between toolkits. The invasion risk of Pterygoplichthys in the River Ding was found to be high and the traits of these fishes that influence their success of becoming established were considered. Some aspects in the use of FISK and AS-ISK as decision-support tools as part of the overall risk analysis of species’ invasions for large risk assessment areas are discussed.

“…This Special Issue comprises 11 papers, with contributions from eight European countries and the USA, with a focus on the temperate zone, but also addressing tropical islands in the Pacific. Pleasingly, these contributions cover the key issues we recognised as most topical, such as the history of invasion and current distribution of invaders (Slovák Švolíková et al 2021, Rakauskas et al 2021, as well as reproductive traits of alien species associated with newly invaded regions (Dashminov & Puzunova 2021, Fuad et al 2021. We were also delighted to receive studies focused on the lifehistory traits associated with invasive success of alien fishes, both in subtropical regions (Lawson & Hill 2021) and tropical Pacific islands (Walsh et al 2021).…”

Originating from the Black and Caspian seas, the Round Goby (Neogobius melanostomus) has become one of the most successful invaders of freshwater ecosystems. In this study, we provide a characterization of the reproductive strategy of an established population of Round Gobies in the Upper Danube river including sex ratio, fluctuations of gonadosomatic index (GSI), analysis of timing of spawning as well as of clutch and egg size. We compare these results to other studies from the native and invaded range. In the Danube, the Round Goby population was found to be female dominated, however fluctuations in magnitude of female bias were observed between months. Monitoring of the population across 1.5 years revealed that GSI was highest from April to June, while lowest values were observed in August and September. Using time‐series analysis, a delayed effect of temperature on GSI was found for females and males, while a quicker response of GSI levels to photoperiod and discharge was observed for females. GSI increased with body size for females and eggs were found to be significantly larger in May, however clutch sizes did not differ between months. Results of a literature review revealed great differences in timing and length of spawning season as well as sex ratio between populations throughout the distribution range, which can probably be explained by climatic and photoperiodic conditions together with the time since invasion and the high plasticity of Round Gobies.
