“…In the present work, we also found that the survival ratio of M. salmoides was significantly higher in the LD group than in the MD and HD groups. In addition, the average survival ratio (80.87%) of M. salmoides in the rice–fish farming system was slightly higher than that (74.47%) in pond-based production systems [ 57 ].…”

Effects of Stocking Density on the Growth Performance, Physiological Parameters, Redox Status and Lipid Metabolism of Micropterus salmoides in Integrated Rice–Fish Farming Systems

Stocking density has been identified as one of the main factors affecting fish growth, welfare and behavior. However, few studies have focused on the effects of stocking density on fish health in integrated rice–fish farming systems. Thus, the aim of this study was to evaluate the effects of different stocking densities on the growth performance, physiological parameters, redox status and lipid metabolism of Micropterus salmoides in an integrated rice–fish farming system. The fish were reared at three densities: low density (LD, 40 g/m3), medium density (MD, 80 g/m3) and high density (HD, 120 g/m3) for 90 days. At the end of the experiment, fish reared in the MD and HD groups showed lower growth performance than those from the LD group. The HD treatment significantly altered the physiological parameters, including glucose and lactate. Meanwhile, the HD treatment induced oxidative stress and lipid peroxidation after 90 days of farming. Furthermore, transcriptomic analysis revealed that HD treatment led to abnormal lipid metabolism. Interestingly, we found the suppression of three key pathways related to lipid metabolism, including the PPAR, insulin and adipocytokine signaling pathways, in the HD group. Overall, our data indicated that the HD treatment inhibited growth and caused physiological responses, oxidative stress and abnormal hepatic lipid metabolism in M. salmoides in an integrated rice–fish farming system.

“…In addition, pellet characteristics (floating vs. sinking and 5.5 mm size vs. 13.0 mm size) have been investigated to determine their effect on growth and feed conversion efficiency [ 16 ]. Furthermore, a vast majority of all food fish LMB raised in the USA are delivered live to ethnic markets in highly populated north American cities [ 17 ]. Finally, the feasibility of a filet market [ 18 ] has also been investigated, although it is not currently economical.…”

As the northern Largemouth bass (LMB) (Micropterus nigricans) industry shifts toward fingerling production, implementing practical feeding strategies to ensure efficient growth during high water temperatures is paramount. Twenty (12.7 ± 0.2 g) (Trial 1) and fifteen (7.2 ± 0.1 g) (Trial 2) LMB fingerlings were stocked in two recirculating systems (each containing nine tanks), acclimated to 30 °C, with one system fed daily rations of 3, 5 and 7% body weight (Trial 1), and the second system fed to satiation daily, every second day, or every third day (Trial 2), for 28 days each. All treatments were triplicated. Multiple growth metrics and lipid composition were analyzed. The 3% treatment yielded the lowest final average weight (36.05 g) and FCR (0.83), with no difference in final biomass in Trial 1 treatments. Fish fed to satiation daily and every second day produced FCRs and biomasses of 0.83 and 356.78 g, and 0.93 and 272.26 g, respectively. There were no differences in total lipid concentration, however, fatty acid profiles differed significantly between all treatments within their respective trials. Feeding LMB fingerlings 3% of total body weight or feeding daily to satiation allows for efficient growth at 30 °C and implements cost-effective feeding strategies.

Shrimp farmers in Alabama are seeking to increase efficiency and intensify production. Semi‐intensive earthen ponds are the traditional production system used by Alabama shrimp farmers; however, there is interest in evaluating intensive pond‐based production systems, such as split ponds. These alternative systems are more intensive and require higher stocking densities to offset capital investment costs required for initial construction and maintenance. Two trials were carried out with Pacific white shrimp Litopenaeus vannamei using on‐levee flow‐through systems (twelve 800‐L tanks per system) at an Alabama shrimp farm to evaluate stocking densities of 29, 88, 176, and 264 shrimp/m2 (trial 1) and higher levels of fish meal (5, 10, and 20%) at a high density of 264 shrimp/m2 (trial 2). Results from trial 1 revealed that as stocking density was increased Pacific white shrimp final weight decreased, while shrimp biomass and feed conversion ratio increased. Survival of Pacific white shrimp at the two highest densities (176 and 264 shrimp/m2) was lower than at the two lowest densities (29 and 88 shrimp/m2). There were no significant differences in performance for Pacific white shrimp offered diets with varying levels of fish meal in trial 2; however, overall survival in trial 2, which was carried out at a high density (264 shrimp/m2), ranged between 47.9% and 65.5%.
