    Abstract: A growth trial was conducted to estimate the optimum levels of dietary phosphorus (P) for juvenile hybrid tilapia (Oreochromis niloticus × O. aureus) fed fishmeal-free practical diets. Hybrid tilapia (1.68 ± 0.08 g) were fed diets containing various levels (0.0%, 0.2%, 0.4%, 0.6%, 0.8% and 1.0%) of additional inorganic phosphorus for 10 weeks using two different sources of phosphorus：calcium dihydrogen phosphate (MCP), and sodium dihydrogen phosphate (MSP). Hybrid tilapia fed the P-supplemented diets showed significantly higher weight gain (WG) and mineral deposition than those fed the unsupplemented diet. Based on weight gain and vertebral phosphorus content, the available phosphorus requirements of hybrid tilapia were estimated as 1% and 1.31% (0.6% and 0.9% based on additional phosphorus content) respectively, when MSP was used as a phosphorus source. When MCP was the phosphorus source, the requirement estimated for weight gain was 0.95% (0.61% based on additional phosphorus content). In addition, MCP contributed to increased growth and a higher mineral deposition rate than did MSP, in freshwater-reared hybrid tilapia.

    Abstract: The objective of this study was to investigate the growth rate and feed conversion ratio (FCR) of juvenile cobia, Rachycentron canadum, in different flow velocities. In experiment A, fifteen groups of fish with an initial mean weight of 14.35 g were reared for 28 days in one of five flow velocities: 0, 5, 10, 15, and 20 cm/s. In experiment B, fifteen groups of fish with an initial mean weight of 30 g were reared for 21 days in the same velocities as in experiment A. In experiment C, fish weighing an average 77 g were raised for 21 days in 0, 10, 20, 30, and 40 cm/s. The opti- mal velocities in terms of growth rate were 10 cm/s for fish of 10-30 g (experiment A), 20 cm/s for fish of 30-60 g (experiment B), and 23 cm/s for fish of 60-200 g (experiment C); the optimal velocity increased as the fish weight increased. FCR and specific growth rate (SGR) also signif- icantly (p 〈 0.05) corresponded to the flow velocity for the different sized juveniles with the opti- mal FCR and weight gains occurring at 10-23 cm/s. FCR rapidly increased when the velocity exceeded 35 cm/s, regarded as the maximum flow velocity for fish growth.

    Effects of Dietary Alpha-ketoglutarate Supplementation on Growth and Serum Biochemical Parameters of Grass Carp (Ctenopharyngodon idella) Fingerlings

    Abstract: An 8-week growth trial was conducted to evaluate the effects of alpha-ketoglutarate (AKG) on growth performance and serum biochemical parameters of grass carp (Ctenopharyngodon idella), and to determine the optimal amount of AKG in feeds. A total of 450 grass carp (mean initial body weight, 35.64±1.39 g) were randomly divided into five treatment groups, with three replicates each. Treatments were, basal diet supplemented with 0% (the control group), 0.25%, 0.5%, 0.75% and 1% AKG, respectively. The results showed that fish fed the 0.75% AKG diet had significantly higher final body weight, weight gain rate (WGR), specific growth rate (SGR), serum superoxide dismutase (SOD) activity, lysozyme (LSZ) activity, and significantly lower feed conversion ratio (FCR), viscerasomatic index (VSI), serum malondialdehyde (MDA), and UREA content than fish fed the control diet (p 〈 0.05)．Fish fed diets containing AKG had significantly higher serum glucose (GLU) content than fish fed the control diet (p 〈 0.05). No significant differences in survival rate (SR), muscle proximate composition, serum total protein (TP) and albumin (ALB) content were observed among the groups (p 〉 0.05). The present study suggests that feed supplementation with 0.75% AKG can promote growth of Ctenopharyngodon idella fingerlings, enhance antioxidant capacity and their non-specific immunity.

    Ionic Liquids‐Based Membranes for Carbon Dioxide Separation

    In: Israel Journal of Chemistry, Wiley, Vol. 59, No. 9 ( 2019-09), p. 824-831
    Abstract: Ionic liquids (ILs) have gained wide‐spread focus owing to its negligible vapor pressure, low heat capacity, high thermal stability, and structural diversity. The solubility and selectivity toward carbon dioxide has made ILs a unique platform that possess the potential in gas separations. In particularly, combining functional ILs with membranes and porous supports is an efficient way to design task‐specific materials for CO 2 separations. This minireview summarizes the developments and advances of ionic liquids‐based membranes for CO 2 separations in recent three years, with an emphasis on the strategy of incorporating ionic liquids and CO 2 separation performance.

    Abstract: The current study evaluated the effect of different dietary plant soot supplementation levels on the intestinal health status of American eels ( Anguilla rostrata ) cultured in concrete tanks. Nine concrete fish tanks were randomly divided into three groups and fed the diets with plant soot (PS) supplementation levels at 0, 3 g/kg, and 5 g/kg, respectively. After a feeding trial for 60 days, the intestinal tissues were sampled to measure health status parameters. The D-lactate level and DAO activity in the serum of the PS5 group were significantly lower than those of the PS0 group (P 〈 0.05). Compared with the PS0 group, the villi length of the intestine in both PS3 group and PS5 group increased significantly (P 〈 0.05). The muscular thickness of the intestine of the PS5 group was significantly higher than the PS0 group (P 〈 0.05). The microvillus density of the intestine of the American eel was increased obviously in the PS5 group. The intestinal microbiota composition of plant soot groups was beneficially regulated with certain probiotics’ higher relative abundances and some pathogenic bacteria’ lower relative abundance. In conclusion, dietary 5 g/kg plant soot supplementation could benefit the intestinal health of farmed American eels.
