Abstract	Hatchery fish stocking is one of the main actions adopted as a form of conservation and replacement of fishing stocks. Under Brazilian law, the release of fish has become mandatory and is seen as one of the main ways of mitigating the negative effects on fish populations and preserving the ichthyofauna. Since its institution, the efficiency of this method has been questioned by the Brazilian scientific community, due to the lack of monitoring based on scientific criteria. The objective of this work was to discuss the few available reports and to analyze their deficiencies and analyze the real risks and/or benefits arising from the methodologies employed in hatchery stocking activities developed in Brazil. For this, three different studies developed in the Paranapanema River, Southeast/South of Brazil, were evaluated seeking evidence of the efficiency or inefficiency of these actions, such as management of the conservation of fish species and stocks. Our analysis shows that this management policy is poorly evaluated, and review of the planning of the stocking programs is essential, in order to improve, update, modernize, and unify the knowledge of the producing stations with respect to the existing ecological and genetic studies, aiming at better monitoring and greater effectiveness in the results advance. Also, a protocol is suggested to standardize and guide new conservationist policies of hatchery fish stocking.

Title translation	Reproductive characteristics of invasive fishes in the Paranapanema River, Upper Paraná River basin, southern Brazil
Abstract	Studies on reproductive biology can provide explanations for successful colonization of new areas, as biological characteristics associated with invasive species may confer advantage on invasion. We aimed at evaluating variations of reproductive characteristics of invasive fishes in lagoons and free-from-dam rivers. Populations of Serrasalmusmarginatus, Loricariichthysplatymetopon, Ossancoraeigenmanni, Auchenipterusosteomystax and Trachelyopterusgaleatus were studied in lentic (Lagoons 1 and 2) and lotic habitats (Pirapozinho and Anhumas rivers) during dry and wet seasons. Females predominated in most populations (χ², α < 0.05). Females of L.platymetopon and T.galeatus presented higher gonadosomatic index during the wet season in the Anhumas River and Lagoon 2, respectively (Mann-Whitney test, α < 0.05). Populations of S.marginatus, L.platymetopon, O.eigenmanni, and T.galeatus showed very intense reproductive activity in Lagoon 1. Trachelyopterusgaleatus showed very intense reproductive activity in the two lagoons and the Pirapozinho River. While some species exhibit high reproductive investment, regardless of habitat type (T.galeatus), others may present variations (S.marginatus and L.platymetopon). Females with higher sex ratios, high reproductive investment, parental care, internal fertilization and split spawning may be features that favor establishment in the recipient area. Serrasalmusmarginatus and L.platymetopon have Equilibrium/Seasonal and Equilibrium life history strategy, respectively, while A.osteomystax e T.galeatus have Seasonal strategy. Due to the presence of individuals that are dispersed, survive and reproduce in different habitat types, these species have an extensive area of occurrence and have successfully invaded the Upper Paraná River basin. Therefore, actions are needed to control populations and minimize their impacts.

Abstract	Understanding the potential distribution of non-native species can be an important tool in preventing biological invasions. We recorded for the first time Psellogrammus kennedyi, a small non-native characiform, in the Lower Paranapanema River, Brazil. According to environmental variables and prediction modeling, the species presents high potential distribution in the Upper Paraná river basin. The model used herein is an efficient tool to determine where non-native species may be able to establish. This approach can be used as a preventive measure, once the control and eradication measures are often ineffective and uneconomical.

Abstract	The combination of highly equipped smartphones, with the increased use of social media, has offered a wide database. Given this, citizen science can be used to record and monitor non‐native fish fauna, target new samples and collaborate with monitoring occurrences in new areas. We aimed to demonstrate the efficiency of social media in citizen science as a tool to cooperate with monitoring studies of non‐native species. Consequently, we determined the occurrence points of S. brasiliensis in the Iguaçu River basin, indicating sites of greatest occurrence and analyzing the impact of the invasion on the native fauna of the basin. Files and information available on the YouTube® and Facebook® media platforms were used as data, was carried out from April 2019 to April 2020. The results were 40 records, 22 videos obtained from Youtube, and seven videos and 11 photos from Facebook, the oldest record was from April 2013, while the largest number of posts was in 2016. Fish records available from online platforms can reveal the occurrence and progressive dispersion of species, in the context of biological invasions, these tools can be of great value in studies that aim to follow the progress of introduced species, contributing by helping to direct new sampling programs and corroborating the occurrence of species in new areas in conjunction with standard monitoring programs. Based on citizen science records, it was possible to update the range of occurrence of the non‐native S. brasiliensis in the Iguaçu River basin, cooperating with scientific knowledge. Innovative monitoring and control measures are necessary to deal with invasive species, with citizen science proving to be competent for determining the occurrence of species and showing promise in the entire field of ichthyology.

Abstract	Understanding the pathways and impacts of non-native species is important for helping prevent new introductions and invasions. This is frequently challenging in regions where human activities continue to promote new introductions, such as in Brazil, where aquaculture and sport fishing are mainly dependent on non-native fishes. Here, the non-native fish diversity of the Paranapanema River basin of the Upper Paraná River ecoregion, Brazil, was quantified fully for the first time. This river has been subject to considerable alteration through hydroelectric dam construction and concomitant development of aquaculture and sport fishing. Through compilation of a non-native fish inventory by literature review, with complementary records from recent field studies, analyses were completed on the timings of introduction, and the taxonomy, origin and introduction vectors of the non-native fishes. A total of 47 non-native fishes are now present across the basin. Of these, 24 invaded from the Lower Paraná River following construction of Itaipu Dam that connected previously unconnected fish assemblages. Activities including fish stocking, aquaculture and sport angling continue to result in new introductions. Discounting Itaipu invasions, the introduction rate between 1950 and 2014 was approximately one new introduction every 3 years. Introduced fish were mainly of the Cichlidae and Characidae families; most species were from other South American ecoregions, but fishes of African, Asian, North American and Central American origin were also present. These introductions have substantially modified the river’s fish fauna; when coupled with altered lentic conditions caused by impoundment, this suggests that the river’s native fishes are increasingly threatened.

Abstract	is a large semi-aquatic rodent ranked as one of the 100 most invasive species in the world. In Brazil, few ecological studies have been proposed to understand the relationship of this species with the environment. To date, drivers that facilitate its establishment in new areas remain unknown. However, it is generally accepted that the natural distribution of this species is limited to far southern Brazil. The present study aimed to understand the geographic distribution of M. coypus and indicate areas of greater risk of establishment based on bioclimatic predictors and a surveillance map. We observed that M. coypus suitability and risk assessment areas are restricted to the southeastern and southern regions of Brazil and that anthropogenic landscape modifications are an adequate variable to explain the occurrence of the species. Due to the environmental impacts caused by this species, monitoring in environments where it has been introduced is required. The model used herein presented efficient applicability and fit for Brazil. Preventive actions and the management of M. coypus in predicted regions prior to its establishment are recommended.

Abstract	Non-native species are a major driver of biodiversity loss. Aquaculture activities play a key role in introductions, including the escape of fishes from fish farm facilities. Here, the impact of flooding due to El Niño rains in 2015/2016 in the Lower and Middle Paranapanema River basin, southern Brazil, was investigated by evaluating fish escapes from 12 fish farms. The flooding resulted in the escape of approximately 1.14 million fishes into the river, encompassing 21 species and three hybrids. Non-native species were the most abundant escapees, especially Oreochromis niloticus (Linnaeus, 1758) and Coptodon rendalli (Boulenger, 1897) (96% of all fish). Only seven native fishes were in the escapee fauna, comprising 1% of all fish. Large floods, coupled with inadequate biosecurity, thus resulted in considerable inputs of non-native fish into this already invaded system.

Abstract	The Tocantins-Araguaia Basin is one of the largest river systems in South America, located entirely within Brazilian territory. In the last decades, capital-concentrating activities such as agribusiness, mining, and hydropower promoted extensive changes in land cover, hydrology, and environmental conditions. These changes are jeopardizing the basin's biodiversity and ecosystem services. Threats are escalating as poor environmental policies continue to be formulated, such as environmentally unsustainable hydropower plants, large-scale agriculture for commodity production, and aquaculture with non-native fish. If the current model persists, it will deepen the environmental crisis in the basin, compromising broad conservation goals and social development in the long term. Better policies will require thought and planning to minimize growing threats and ensure the basin's sustainability for future generations.
