“…Given the growing interest in this species for aquaculture purposes, the implementation of well-isolated farming systems with minimal risk of escape might be sustainable [4,150,217]. Indeed, farming largemouth bass can lead to environmental impacts on nearby water bodies and further favor the spread of this species [150,217], possibly due to the discharge of high-temperature fish-farming wastewaters, along with feed and/or drugs, into nearby freshwater bodies [30,217]. The use of intelligent feeding strategies coupled with microalgae, which can reduce the nutrient load, could mitigate the negative effects on receiving and nearby water bodies [217].…”

Biological invasions in fresh waters cause biodiversity loss and impairment of ecosystem functioning. Many freshwater invasive species are fish, including the largemouth bass Micropterus salmoides, which is considered one of the 100 worst invasive species in the world. Fast individual growth rates, high dispersal ability, ecological tolerance, and trophic plasticity are among the characteristics contributing to its success. The negative impact of M. salmoides on littoral fish communities is believed to be mitigated by habitat structural complexity resulting from aquatic vegetation and coarse woody debris, while the main limits on its spread seem to be strong water flows and high turbidity, which impairs visual predation. Together with the human overexploitation of its potential fish antagonists, habitat alteration could result in M. salmoides having seriously detrimental effects on native biodiversity. The purpose of this study is to critically review the life history and ecology of M. salmoides, its impact on ecosystems outside North America, and the effects of anthropogenic activities on its spread. This will highlight environmental factors that favor or limit its invasive success, helping to identify management measures that might mitigate its negative effects on freshwater biodiversity.

“…However, results from the literature are not always consistent. In addition, because M. salmoides is one of the most sought-after species for sport fishing and has nutritional value for fish farming, the costs and benefits of its introduction and spread have generated much controversy [25,[30][31][32].…”

“…However, problems have occurred as high-density rearing continuously existed. Frequent outbursts of infectious diseases caused by aquatic pathogens strongly limited the farming industry of M. salmoides [2,3], bringing serious economic losses to the fishery and impeding the sustainable development of aquaculture [4]. Therefore, preventive and therapeutic methods are highly required to counteract pathogen infections and subsequent diseases.…”

The present study investigated the effects of Astragalus membranaceus extract (AME) on growth performance, immune response, and energy metabolism of juvenile largemouth bass (Micropterus salmoides). Seven diets containing 0%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, and 0.6% AME (Con, AME0.1, AME0.2, AME0.3, AME0.4, AME0.5, and AME0.6 groups) were formulated and fed to M. salmoides for 8 weeks. Final body weight (FBW), feed intake (FI), weight gain (WG), and specific growth rate (SGR) were all significantly higher in AME0.4 group than in Con group (P<0.05). Feed conversion rate (FCR) was significantly improved in AME0.5 group compared with Con group (P<0.05). Whole-body crude protein contents were significantly increased in AME0.2 group (P<0.05). Whole-body crude lipid contents were significantly lower in AME0.2 and AME0.3 groups, while muscle lipid was upregulated by dietary AME (P<0.05). Hepatic malondialdehyde (MDA) contents were significantly lowered in AME0.3 and AME0.4 groups, and catalase (CAT) activities were significantly increased in AME0.1 and AME0.2 groups (P<0.05). Plasma aspartate aminotransferase (AST) level was significantly lowered in AME0.5, and AME0.6 groups, and alanine aminotransferase (ALT) level was lowered in AME0.5 groups (P<0.05). Plasma triglyceride was declined in AME0.6 group, and glucose was decreased by 0.3%−0.5% AME (P<0.05). Significantly higher hepatocyte diameter, lamina propria width, and submucosal layer thickness were recorded in AME0.6 groups, while the longest villi height was obtained in AME0.2 and AME0.3 groups (P<0.05). The mRNA expression levels of insulin-like growth factor 1 (igf1) revealed the growth-promoting effect of AME. The anti-inflammatory and antiapoptotic effects of AME were demonstrated by transcription levels of interleukin 8 (il-8), tumor necrosis factor-alpha (tnf-a), caspase, B-cell lymphoma-xl (Bcl-xl), bcl-2 associated x (Bax), and bcl-2-associated death protein (Bad). The transcription levels of lipid metabolism and gluconeogenesis related genes, including acetyl-CoA carboxylase alpha (acc1), fatty acid synthase (fasn), fatty acid binding protein 1 (fabp1), phosphoenolpyruvate carboxykinase 2 (pepck2), and glucose-6-phosphatase catalytic subunit 1a (g6pc), were reduced by AME treatment, while the levels of glycolysis-related genes, including glucokinase (gck) and pyruvate kinase (pk), were the highest in AME0.2 and AME0.3 groups (P<0.05). According to polynomial regression analysis of SGR, WG, FCR, whole-body crude lipid, MDA, and ALT, the optimal AME supplementation level was estimated to be 0.320%−0.429% of the diet. These results provided insights into the roles of AME in regulating immunity and metabolism, which highly indicated its potential as immunostimulants and metabolic regulators in diverse aquatic animals.

“…Rhabdoviruses are extensively disseminated in natural world, with such a variety of host that includes plants, crustacean, insects, sh, and mammals. Since the rst hemorrhagic sepsis virus strain was isolated from the diseased Oncorhynchus mykiss in 1962, there has been exceeding 20 sh rhabdoviruses have been described (Chen et al, 2022), including Micropterus salmoides rhabdovirus (MSRV) (Wu et al, 2023), spring viremia of carp virus (SVCV) (Bessaid et al, 2023), perch rhabdovirus (PRV) (Caruso et al, 2019), hybrid snakehead rhabdovirus (HSHRV) (Zeng et al, 2014), snakehead vesiculovirus (SHVV) (Feng et al, 2019), Siniperca chuatsi rhabdovirus (SCRV) (Liu et al, 2023) which can all infect Perciformes. In China, sh rhabdovirus was rst isolated from Siniperca chuatsi in 1999 (Zhang and Li, 1999).…”

Siniperca chuatsi rhabdovirus (SCRV) has caused severe disease and mortality in commercial sh in China. To investigate the molecular relationships between pathogen and host, transcriptome analysis of SCRV-infected and non-infected E11 cells was obtained using the Illumina HiSeq X Ten sequencing system. There was 29,894 unigenes assembled and a total of 4137 differentially expressed genes (DEGs), consisting of 2189 up-regulated and 1948 down-regulated unigenes were detected between SCRV-infected and non-infected E11 cells. To understand the immune response of the virus in the host, pathway function analysis indicates that SCRV infection affected 31 typical immune-related pathways, including MAPK signaling pathway, PI3K-Akt signaling pathway, Endocytosis and Apoptosis, suggesting that E11 cells resist SCRV invasion through these innate immune pathways. Overall, qRT-PCR results showed similar expression to Illumina HiSeq, with reliable sequencing results. These results provided some vital clues which will be helpful to future study on SCRV-host interactions.
