“…Espécies exóticas invasoras como o mosquito-da-dengue (Aedes aegypti) e abelha-africana (Apis mellifera) são muito comuns em áreas urbanas e periurbanas e trazem importantes impactos para a saúde humana e a economia (Adelino et al 2021;Tavares-Blancher et al 2023). No caso de peixes, a poluição da água decorrente da poluição tem favorecido espécies exóticas invasoras, em particular o guppy (Poecilia reticulata) (Bueno et al 2023). É provável que no futuro breve aumentem as chegadas e estabelecimentos de espécies exóticas em ecossistemas antrópicos, principalmente em áreas urbanas e periurbanas.…”

After extensive aquaculture, urbanization, and industrial development, the Pearl River Delta (PRD) has undergone profound environmental changes, with biological invasion emerging as a consequential anthropogenic byproduct, carrying significant implications for natural ecosystems, human health, and the economy. Despite these transformations, our understanding of nonnative fish species and their adaptability to the dynamic environmental conditions within the intricate river network of the PRD remains incomplete. To address this, we conducted a systematic survey of nonnative fish species in PRD waters through literature reviews. Then we analyzed the salinity adaptation of these fish, coupled with a spatial examination of salinity distribution, to comprehensively understand the potential invasion mechanisms of exotic fish in the region. Our findings identified 25 nonnative fish species in PRD waters, with three being translocated species within China and the remaining 22 being exotic introductions. Phylogenetically, these fish are broadly distributed among several orders, with Cichliformes, Perciformes, Cypriniformes, and Siluriformes emerging as the predominant orders. Despite most of the nonnative fish being freshwater species and exhibiting species-specific differences in salinity adaptability, they generally demonstrated an average salinity tolerance of 23.74 ppt, allowing them to adjust to brackish water. The diversity of species declined as the relative distance decreased from the upstream of the Pearl River Estuary (PRE) to its mouth in the sea (p < 0.01). Spatial analysis unveiled pronounced heterogeneity in salinity distribution, particularly in the east PRE of the LingDing Bay, featuring a sizable area with brackish water. Notably, under salinity intrusion circumstances, a gap region between salinity levels of 5.0 ppt and 15.0 ppt, spanning 3111.2 km2, emerged as a potential adaptation zone for nonnative fish. By emphasizing salinity as a key factor, our study may contribute to elucidating invasion mechanisms and enhancing the assessment of invasion risks in estuarine environments.

The Pearl River Delta (PRD) has undergone significant environmental changes resulting from anthropogenic activities, with bio-invasion emerging as one of the most consequential byproducts. Despite these apparent transformations, our understanding of nonnative fish species and their adaptability to the environment remains incomplete, compounded by the complexity of the river network. To address this, we conducted a literature survey to screen the nonnative fish species. Subsequently, we analyzed the fish's salinity adaptation capability, spatial variations in alpha diversity, and trophic level. Thirdly, we simulated the distribution of salinity under conditions of salinity intrusion. Our findings identified 25 nonnative fish species, phylogenetically belonging to nine orders, with three being translocated species within China and the remaining 22 being exotic introductions. Although most of the nonnative fish are freshwater species and exhibit species-specific differences in salinity tolerance, they generally can adapt to brackish water, with an average salinity tolerance of 23.74 ppt. The diversity of nonnative fish declined as the relative distance decreased from the upstream of the Pearl River Estuary (PRE) to its mouth in the sea (p < 0.01). Spatial analysis unveiled pronounced heterogeneity in salinity distribution, particularly in the east PRE of the LingDing Bay. Notably, under salinity intrusion circumstances, a gap region between salinity levels of 5.0 ppt and 15.0 ppt, spanning 3111.2 km2, emerged as a potential adaptation zone for nonnative fish. By emphasizing salinity as a key factor, our study may contribute to elucidating invasion mechanisms and enhancing the assessment of invasion risks in estuarine environments.
