Comparative study on the morphological characteristics and nutritional quality of largemouth bass (Micropterus salmoides) cultured in an aquaculture system using land-based container with recycling water and a traditional pond system

Effects of Submerged Macrophytes on the Growth, Morphology, Nutritional Value, and Flavor of Cultured Largemouth Bass (Micropterus salmoides)

“…Meanwhile, in the present experiment, largemouth bass cultured in the presence of submerged macrophytes were slender, with a green body. Our observations are consistent with reported findings in largemouth bass cultured in an aquaculture system using land-based containers with recycled water [ 6 ]. Moreover, fish in the M group showed a significantly higher HSI, suggesting that largemouth bass cultured in the conventional model produced excess body energy, which led to lipid and glycogen accumulation in the liver.…”

“…Thus, accurately describing the composition of volatile substances can help assess the quality of agri-food products [ 23 , 47 ]. Various flavor components of largemouth bass meat have been documented [ 5 , 6 ]. In the present study, 24 aldehydes accounted for 43.64% of all components and were the most abundant volatile compounds in largemouth bass muscles.…”

“…Furthermore, ketones are produced through lipid oxidation and generate creamy and fruity notes [ 57 ]. 2-Butanone was abundant in the muscles of largemouth bass in a recirculatory aquaculture system [ 6 ]. In the present study, 2-butanone accounted for approximately 50% of all ketones, being the most abundant one.…”

“…Owing to its rapid growth, delicious flavor, and lack of intermuscular bones, largemouth bass has become widely popular in China since its introduction in 1983 [ 5 ]. At present, traditional pond systems remain the only acceptable mode of largemouth bass culture in China [ 6 ]. During pond culture, artificial compound feed is supplied, which leads to eutrophication, thereby promoting the outbreak of bloom-forming cyanophytes and diseases and ultimately deteriorating the quality of aquaculture products [ 7 , 8 ].…”

Genetic diversity analysis and development of molecular markers for the identification of largemouth bass (Micropterus salmoides L.) based on whole-genome re-sequencing

“…Because of their geographical distribution differences, it was reported that NB is more tolerant to low temperature, ammonia nitrogen, and low oxygen, while FB is more resistant to high temperatures and has a stronger stress response ( Philipp et al, 1983 ; Fields et al, 1987 ; Carmichael et al, 1988 ; Williamson and Carmichael, 1990 ; Khosa et al, 2020 ). Abiotic stresses (e.g., heat, chilling, nutritional imbalance, and water quality) are one of the major factors which restrict the growth and development of largemouth bass ( Li et al, 2020 ; White et al, 2020 ; Jia et al, 2022 ). Especially the high temperatures in the summer and autumn seasons, which commonly result in reduced food intake, declined growth rates and disease resistance of largemouth bass ( Lin et al, 2022 ).…”
