“…The introduction of icefishes has brought significant economic benefits but, simultaneously, jeopardized biodiversity in native assemblages [ 48 , 53 , 54 ]. Both P. chinensis and N. tangkahkeii are reported to be successful invasive species [ 47 , 48 , 53 , 55 , 56 , 57 ].…”

The interspecific recombination of the mitochondrial (mt) genome, if not an experimental artifact, may result from interbreeding of species with broken reproductive barriers, which, in turn, is a frequent consequence of human activities including species translocations, habitat modifications, and climate change. This issue, however, has not been addressed for Protosalanx chinensis and other commercially important and, simultaneously, invasive salangid fishes that were the product of successful aquaculture in China. To assess the probability of interspecific hybridization, we analyzed the patterns of diversity and recombination in the complete mitochondrial (mt) genomes of these fishes using the GenBank resources. A sliding window analysis revealed a non-uniform distribution of the intraspecific differences in P. chinensis with four highly pronounced peaks of divergence centered at the COI, ND4L-ND4, and ND5 genes, and also at the control region. The corresponding divergent regions in P. chinensis show a high sequence similarity (99–100%) to the related salangid fishes, Neosalanx tangkahkeii and N. anderssoni. This observation suggests that the divergent regions of P. chinensis may represent a recombinant mitochondrial DNA (mtDNA) containing mt genome fragments belonging to different salangid species. Indeed, four, highly significant (pairwise homoplasy index test, P < 0.00001) signals of recombination have been revealed at coordinates closely corresponding to the divergent regions. The recombinant fragments are, however, not fixed, and different mt genomes of P. chinensis are mosaic, containing different numbers of recombinant events. These facts, along with the high similarity or full identity of the recombinant fragments between the donor and the recipient sequences, indicate a recent interspecific hybridization between P. chinensis and two Neosalanx species. Alternative hypotheses, including taxonomical misidentifications, sequence misalignments, DNA contamination, and/or artificial PCR recombinants, are not supported by the data. The recombinant fragments revealed in our study represent diagnostic genetic markers for the identification and distinguishing of hybrids, which can be used to control the invasive dynamics of hybrid salangid fishes.

This research was carried out in the Katamadari River, which is located in the northern part of Bangladesh, to acquire information regarding the contemporary status of ichthyofaunal variation and their conservation. Over the course of a year from June 2020 to May 2021, a combined approach was adopted to collect data, which included collecting fish samples from fishers and fish traders as well as administering a survey. A total of 62 fish species were identified in the river, including three exotic species, and two prawn species. Out of ten observed orders, Cypriniformes, Siluriformes, and Perciformes were found to be the most dominant, consisting of 19, 16, and 14 fish species respectively. Fishes from Cyprinidae family were revealed to be the most abundant, accounting for about 27.5% of the total fish composition. Besides, among the thirteen common fish groups, catfish’s contribution was the highest followed by perches, carps, and barbs and minnows. However, almost a quarter of all fish species were under threatened category: seven vulnerable, eight endangered, and two critically endangered. Approximately 50% of the total fish species were examined to be rare and very rare. The current study also documented a range of anthropogenic as well as natural threats to the aquatic biodiversity of the river, all of which have devastating impacts. Ann. Bangladesh Agric.

“…This pattern underscores the essential role played by translocated species in driving the process of biotic homogenization and shaping the historical composition of freshwater fish faunas. Therefore, it is imperative to broaden the focus of future prevention and management efforts on both alien species and translocated species (Jiang et al, 2021; Vitule et al, 2019), particularly for hotspots like Yunnan with a high endemic biodiversity.…”

AimAnalysing the spatio‐temporal patterns and dynamics of non‐native species is essential to understanding the mechanisms underlying successful invasions and developing effective management strategies. Yet, such analyses generally neglect the influence of receiving ecosystem types and non‐native species sources (i.e. alien species, non‐natives originating outside the concerned region; translocated species, non‐natives introduced to locations outside their historical range within the concerned region).LocationYunnan, China.MethodsWe analysed long‐term (1950–2022) spatio‐temporal patterns and potential underlying dynamics of non‐native fishes in a biodiversity hotspot (Yunnan, China), paying special attention to waterbody types receiving non‐native species and comparing alien and translocated species. We did this through compiling a highly comprehensive occurrence dataset of native and non‐native fishes.ResultsWe recorded 783 native species and 94 non‐native species (49 alien species and 45 translocated species), which mainly belonged to the order Cypriniformes (52 species) and were introduced via purposes for advancing aquaculture. Most frequently encountered non‐native species were either intentionally introduced aquaculture species or small‐bodied fish unintentionally introduced via aquaculture activities. The richness and spatial ranges of non‐native fishes increased consistently since the 1950s and demonstrated a pronounced change after the 2000s, with densely populated areas and the middle to lower reaches of large rivers being more profoundly affected. The number of records of translocated species exceeded the number of records of alien species after the 2000s. Lakes and reservoirs are hotspots for both alien and translocated species introductions, and watersheds with large areas in Yunnan (e.g. the Jinsha‐Yangtze and Lancang‐Mekong basins) contained more non‐native fish.Main ConclusionsOur study highlights the need to consider invasion sensitivities of receiving ecosystems and pay special attention to intra‐regional species translocations when developing prevention and management strategies against invasions of alien species, particularly in important biodiversity hotspots around the world.
