Summary: The study found that the optimal feeding frequency for largemouth bass reared in pond was 3 meals per day, and 2 meals per day for those reared in in-pond raceway. The in-pond raceway system was not suitable for commercial largemouth bass farming.

Summary: Threonine significantly influenced the growth and feed utilization of largemouth bass, with the optimal supplemental level identified as 5.0 g kg-1. Increased threonine supplementation initially led to higher weight gain and specific growth rate, but then showed a decrease in these parameters.

Summary: A new strain of Micropterus salmoides rhabdovirus (MSRV-NY01) was isolated from largemouth bass in China, causing severe disease and economic losses. The virus was identified and isolated using various methods, and it was found to have high pathogenicity in largemouth bass. The results of this study provide new material and information for the prevention and control of MSRV.

Summary: In this study, oral vaccines against largemouth bass ranavirus (LMBV) infection were prepared using yeast surface display technology. The candidate vaccines showed enhanced immune response and effective protection against LMBV infection after continuous oral immunization. These findings suggest that EBY100-OMCP and EBY100-LTB-OMCP are promising and effective candidate vaccines against LMBV infection.

Summary: In this study, we identified and confirmed the presence of iridovirus and rhabdovirus members as the likely pathogens in diseased largemouth bass. Co-infection with these viruses was observed, leading to higher mortality rates compared to single infections. The viruses were found to be most similar to largemouth bass virus and hybrid snakehead rhabdovirus. Our findings provide novel ideas for the prevention and treatment of combined virus infection, particularly in largemouth bass.

Summary: This study aimed to evaluate the effectiveness of different commercial diets and one experimental feed for indoor weaned largemouth bass. The key variations in nutritive values were monounsaturated fatty acids (MUFA) and highly unsaturated fatty acids (HUFA) omega-3. The results showed that the balanced lipid composition and amino acid balance in the diet were the main contributors to skeletal growth and fish survival. Additionally, the study found that fish growth was correlated with digestive capacity and feed moisture percentage.

Summary: This study evaluated classification algorithms to predict largemouth bass occurrence in South Korea and found that random forest was the best model. Annual mean temperature and fall mean temperature were the most important environmental variables.

Summary: This study described the pathological characteristics of Micropterus salmoides infected with Nocardia sp. and found differences in the pathological features in recent years, indicating a more serious disease in Micropterus salmoides. The results suggest that the pathogenicity of Nocardia sp. infecting Micropterus salmoides may have improved.

Summary: TRIM21 plays important roles in apoptosis, autophagy, and ubiquitination in humans, and has been shown to have antiviral roles in different organisms. In this study, the TRIM21 gene of Micropterus salmoides (MsTRIM21) was cloned and its expression was found to be altered during viral infection. Overexpression of MsTRIM21 can inhibit viral replication and enhance innate immune and inflammatory responses, potentially affecting viral replication.

Summary: The study successfully developed an in vitro methodology for carp muscle hydrolysis using LMB endogenous digestive enzymes and found that the inclusion of carp muscle hydrolysate in the diet improved the growth performance of larval LMB, while also reducing skeletal deformities. The positive growth performance might be attributed to meeting the specific requirements of the larvae in terms of their digestive organ development, levels of digestive enzymes, and nutritional needs.

Summary: The phagocytic capacity of largemouth bass leukocytes, particularly granulocytes/monocytes, was observed against fluorescent microspheres and Aeromonas hydrophila. Up-regulation of phagocytosis-related genes and TNF-alpha was observed in the leukocytes following A. hydrophila stimulation. Recombinantly expressed TNF-alpha in largemouth bass significantly enhanced the phagocytic ability of granulocytes/monocytes and increased their ROS activity, while also inducing apoptosis.
