Invasive Mozambique tilapia (Oreochromis mossambicus), dominates Southeastern Caribbean Sea island estuary

Abstract and Figures

Some structural and population aspects of the fish community of Laguna de Los Mártires, a small positive estuary (1.9-25 PSU), located on Isla de Margarita, in the Southeast Caribbean Sea, were studied. During a year of monthly sampling at five stations, only 10 fish species were recorded. Of these, Oreochromis mossambicus (Peters 1852), was the only one caught in all seasons throughout the year, with higher abundance (39.8%) and relative biomass (54.3%), frequency of occurrence (100%) and Importance Valuation Index (194.1). The invasive success of this species was also evidenced by a high abundance of juveniles (65%), continuous reproduction and rapid growth. Its effects on the native fish community was also observed in the ecological indices, with low values of Species Richness (S: 1-6 species), Diversity (H: 0-0.94) and Equity (J: 0.13-0.54), and high Community Dominance Index (CDI: 0.4-0.9). A high anthro-pogenic impact was also observed in the Laguna de Los Mártires, due to the contamination of the waters and physical modification of the habitat. This characterizes a highly deteriorated ecosystem, with a poor fish community, product of the synergy between the dominance of O. mossambicus over the native fish community, as well as the alteration of the habitat (invasive meltdown). Systematic extraction of the population of this invader in the lagoon is recommended to improve the environmental conditions of this ecosystem and the recovery of the biota. Cite as: Rodríguez, E. E.

Non-native fish (NNF) can threaten megadiverse aquatic ecosystems throughout the planet, but limited information is available for the Amazon Region. In this study we review NNF data in the Amazonian macroregion using spatiotemporal records on the occurrence and the richness of NNF from a collaborative network of 35 regional experts, establishing the Amazon NNF database (ANNF). The NNF species richness was analyzed by river basin and by country, as well as the policies for each geopolitical division for the Amazon. The analysis included six countries (Brazil, Peru, Bolivia, Ecuador, Venezuela, and Colombia), together comprising more than 80% of the Amazon Region. A total of 1314 NNF occurrence records were gathered. The first record of NNF in this region was in 1939 and there has been a marked increase in the last 20 years (2000–2020), during which 75% of the records were observed. The highest number of localities with NNF occurrence records was observed for Colombia, followed by Brazil and Bolivia. The NNF records include 9 orders, 17 families and 41 species. Most of the NNF species are also used in aquaculture (12 species) and in the aquarium trade (12 species). The most frequent NNF detected were Arapaima gigas, Poecilia reticulata and Oreochromis niloticus. The current data highlight that there are few documented cases on NNF in the Amazon, their negative impacts and management strategies adopted. The occurrence of NNF in the Amazon Region represents a threat to native biodiversity that has been increasing “silently” due to the difficulties of large-scale sampling and low number of NNF species reported when compared to other South American regions. The adoption of effective management measures by decision-makers is urgently needed and their enforcement needed to change this alarming trend and help protect the Amazon’s native fish diversity.

The Indo-Pacific octocoral Xenia sp. has been reported as a successful invasive species of the Venezuelan coral reefs (Southeastern Caribbean Sea), and the first xeniid octocoral with such invasive properties. This taxon has been recently identified, and assigned to a new genus and combination as Unomia stolonifera. Since its first appearance there, it has dispersed along the shallow reefs, overgrowing any hard substrate, including corals and seagrass. Quantitative surveys revealed that U. stolonifera dominated all studied sites, featuring an average percentage cover of 30 - 80%, far above that of the native corals or any other benthic taxa. An inverse relationship exists between the loss of diversity and the reduction in coral cover. The spread of U. stolonifera in places where it has become established while displacing native benthic species and leads to a decrease in diversity and evenness of the benthic communities. Dispersal of the invasive along the reefs has been intensified by drifting colonies, by colonies settled on detached Thalassia testudinum fragments and, additionally, by colonies entangled on fish nets and consequently translocated. The present study explicitly demonstrates that this intensifying invasion is causing severe ecological damage to the Venezuelan reefs. Consequently, Unomia stolonifera, should be considered harmful invasive species that requires monitoring and management programs in the vicinity of already invaded reefs. The current study highlights the ecological consequences of this new invasive species.

Rivers of French Guiana are still little invaded by non-native fish, but several fish introductions were recently recorded through the development of aquarium fish trade and fish farms. Here we report records of 11 non-native fish species. Among them, four (Cichla monoculus, Heros efasciatus, Mesonauta guyanae and Poecilia reticulata) are established and one of them (Heros efasciatus) is rapidly increasing its spatial range. Two species (Hyphessobrycon eques and Pterophyllum scalare) were not retrieved in recent records and are probably extinct from French Guiana. The establishment status of the five other species (Arapaima gigas, Colossoma macropomum, Cyprinus carpio, Oreochromis mossambicus and Osteoglossum bicirrhosum) is uncertain and only a few specimens were observed in the wild. Nevertheless, these species, intensively reared in nearby countries, belong to highly invasive species able to cause detrimental impacts on recipient ecosystems. Those first occurrences of invasive fish species in French Guiana should therefore act as an early warning for both researchers and environmental managers.

Biological invasions are a global consequence of an increasingly connected world and the rise in human population size. The numbers of invasive alien species – the subset of alien species that spread widely in areas where they are not native, affecting the environment or human livelihoods – are increasing. Synergies with other global changes are exacerbating current invasions and facilitating new ones, thereby escalating the extent and impacts of invaders. Invasions have complex and often immense long‐term direct and indirect impacts. In many cases, such impacts become apparent or problematic only when invaders are well established and have large ranges. Invasive alien species break down biogeographic realms, affect native species richness and abundance, increase the risk of native species extinction, affect the genetic composition of native populations, change native animal behaviour, alter phylogenetic diversity across communities, and modify trophic networks. Many invasive alien species also change ecosystem functioning and the delivery of ecosystem services by altering nutrient and contaminant cycling, hydrology, habitat structure, and disturbance regimes. These biodiversity and ecosystem impacts are accelerating and will increase further in the future. Scientific evidence has identified policy strategies to reduce future invasions, but these strategies are often insufficiently implemented. For some nations, notably Australia and New Zealand, biosecurity has become a national priority. There have been long‐term successes, such as eradication of rats and cats on increasingly large islands and biological control of weeds across continental areas. However, in many countries, invasions receive little attention. Improved international cooperation is crucial to reduce the impacts of invasive alien species on biodiversity, ecosystem services, and human livelihoods. Countries can strengthen their biosecurity regulations to implement and enforce more effective management strategies that should also address other global changes that interact with invasions.

The conservation challenges facing freshwater ecosystems necessitate broadening our science from understanding individual species loss to anticipating multi-faceted changes to biodiversity. In recent decades, the process of biotic homogenization by which regional biotas become more similar through time has attracted considerable attention. Here, we (1) quantified spatial and temporal changes in taxonomic and functional similarity of fish assemblages among Neotropical reservoirs, (2) determined nonnative species contributions to changes in taxonomic and functional composition, and (3) evaluated relationships between the changes in taxonomic and functional similarity among reservoirs. We did so by considering different spatial scales: inter- and intra-ecoregions. At inter-ecoregion scale, reservoir fish assemblages have become taxonomically homogenized over time, whereas functional trait composition has tended to differentiate. At intra-ecoregion scale, we detected both taxonomic and functional differentiation over time. Despite these overall trends, different ecoregions exhibited considerable variation in patterns of fish faunal homogenization and differentiation. We found a moderate positive relationship between changes in mean taxonomic and functional similarity among reservoirs at inter-ecoregion scale, which was no longer evident within ecoregions. In conclusion, this study demonstrates the strong scale-dependence of perceived patterns in homogenization, and further highlights the magnitude of threats to freshwater biodiversity in the Neotropical ecosystems.

The potential role of positive interactions among co-invaders is at the core of the invasional meltdown hypothesis. The interaction of non-native species could result in an exacerbation of each other’s effects. Thus, the resulting effect of multiple non-native species on ecosystems can be greater than the sum of their individual effects. We designed an analytical framework and a set of mesocosm experiments to assess the potential synergistic effects of three non-native species (Limnoperna fortunei, Astronotus crassipinnis, and Hydrilla verticillata) in a highly invaded floodplain in southern Brazil. We analyzed ecosystem, community, and population attributes in scenarios with non-natives. Our hypothesis of a synergistic effect was not supported. Even though effects of the invasive species were detected for all ecological levels, evidence indicated that these effects were additive. In addition to adding to the statement that origin (i.e., native vs. non-native status) does matter, we provide a tool to differentiate additive, synergistic, and antagonistic effects in situations with multiple invasions, and experimentally demonstrate additive effects of non-native species at different ecological levels.

Aim: To provide an overview of ecology and management of invasive species in riverine ecosystems. Key findings: ●Aquatic invasive species are a primary threat to streams and rivers across the globe, impacting biodiversity, disrupting key ecological functions, and compromising ecosystem services. ●Invasive species are those that are transported out of their native range, introduced into a novel location, establish self-sustaining populations by surviving and reproducing, spread to new locations, and have negative ecological and/or economic impacts in the recipient ecosystem. ●Species can enter a new region by being imported as or with a commodity associated with the direct human movement of goods, by hitchhiking on human modes of transport, and by dispersing unaided by themselves along infrastructure corridors. ●The likelihood of nonnative species to establish new self-sustaining populations depends on propagule pressure, biological attributes of the species, environmental characteristics of the ecosystem, and biotic interactions with recipient communities. ●The ecological impacts of aquatic invasive species are manifested at different scales from genes to ecosystems. ●Aquatic invasive species have caused enormous economic impacts associated with their management and mitigation of their damages. ●A diversity of management strategies and policy options are available to prevent, contain, control and eradicate aquatic invasive species. Conclusions: The future health of riverine ecosystems will depend on how societies manage current invasive species and whether the arrival of future invasive species can be successfully prevented, or their impacts minimized.

We report for the first time the infection of dolphins with Ascocotyle longa found in the intestines of three different species, Sotalia guianensis, Steno bredanensis, and Tursiops truncatus gephyreus, which were found washed ashore along the southeastern and southern Brazilian coast. The worms were identified based on morphological and molecular data using the 28S rDNA gene and the COI gene. Specimens of A. longa from the pinniped Otaria flavescens were also analyzed. As the first isolation of A. longa from cetaceans, the present study increases the distribution area and range of definitive hosts of this trematode, and provides new molecular data to complement the phylogeny of the group in future studies, thus contributing to the scientific knowledge of this potentially zoonotic parasite.

In this study we sequenced two mitochondrial (COI and 16S rRNA) and one nuclear (18S rRNA) gene fragment of an introduced muzzled blenny (Omobranchus punctatus) specimen collected from the Orinoco Delta (Gulf of Paria estuary), in Venezuela. This is the first genetic data generated for this species' introduced range in Central and South American, suggesting an introduction from the Indian Ocean.
