“…We observed that LZM activity in the liver increased significantly with incremental increases in dietary valine up to 12.7 g/kg, but then decreased with further increases in valine, suggesting that valine content in the diet has a significant effect on LZM activity in the liver of juvenile Nile tilapia. Similar results were found for Nile tilapia fed diets of different leucine levels (Gan et al, 2015) and for red sea bream fed diets of different valine levels (Lin et al, 2015). SOD and CAT are two important enzymes in the Values are the means of triplicate groups and presented as mean ± SD (n = 3).…”

An 8‐week feeding trial was conducted to quantify the dietary valine requirement of cultured juvenile Nile tilapia, Oreochromis niloticus. Six isonitrogenous (280 g/kg crude protein) and isoenergetic (16.06 MJ/kg gross energy) diets with graded levels of valine (amounting to 4.1, 7.2, 9.9, 12.7, 15.6 and 18.8 g/kg of dry diet) were formulated. Each diet was randomly assigned to triplicate groups of 20 fish (6.48 ± 0.06 g). Results showed that the weight gain, specific growth rate, protein efficiency ratio and protein retention efficiency all increased with an increasing level of dietary valine up to 12.7 g/kg, but remained relatively constant for fish fed higher levels of dietary valine. In addition, the total protein concentration and aspirate aminotransferase activity in plasma, hepatic lysozyme and catalase activities were all significantly (p < .05) improved by dietary valine supplementation. Based on the broken‐line regression analysis of weight gain and protein retention efficiency, the optimal dietary valine requirement for juvenile Nile tilapia occurred between a level of 11.5 g/kg of diet (equivalent to 41.1 g/kg of dietary protein) and 12.7 g/kg of diet (equivalent to 45.3 g/kg of dietary protein).

“…In size II fish, the same tendency was observed in those fed 18.1 g kg -1 dietary arginine level. This result inconsistent with the results of Lin et al (2015) on golden pompano Trachinotus ovatus. This illustrated that arginine level might affect the whole amino acid deamination and the metabolism (Tu et al, 2015), and this might be another reason for reduced growth and feed efficiency in fish (size I and II) fed excess dietary arginine.…”

This trial was conducted to investigate the dietary arginine requirement in two sizes of blunt snout bream (Megalobrama amblycephala). Six isonitrogenous and isoenergetic (34% crude protein) diets containing graded levels of arginine from 8.3 to 33.6 g kg -1 . Triplicates of 30 fishes (body weight 52.50±0.18g) of size I or 20 fishes (body weight 101.85±1.85g) of size II were fed with one of six experimental diets. Specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER) and weight gain (WG) significantly increased with the increase of arginine levels from 8.3 to 23.5 g kg -1(size I) or from 8.3 to 18.1 g kg -1(size II), and thereafter, kept decrease. The alanine aminotransferase (ALT) was significantly decreased with increase in dietary arginine levels from 8.3 to 23.5 g kg -1in size I or 8.3 to 18.1 g kg -1 of the size II (P<0.05). Urea content first significantly increased (P<0.05), and showed the same trend in two sizes. Meanwhile, plasma arginine concentration of two sizes significantly increased with increasing dietary arginine from 8.3 to 23.5 g kg -1 (P<0.05), and significantly lower lysine content in plasma was observed in fish fed diets with arginine levels from 8.3 to 23.5 g kg -1 (P<0.05). Broken-line regression model analysis relation on the basis of SGR, the optimal dietary arginine requirement could be 20.3 g kg -1 in size I, and 17.9 g kg -1 in size II of dry matter, respectively. The results may explain the adverse effects of a deficient or an excess dietary arginine level on growth and health of fish in future. Furthermore, the present study also suggests that an optimum dietary arginine could play an important role in improving growth, and maintaining health for different size of fish, which would be useful in developing amino acid balanced commercial feeds for blunt snout bream.

“…The 12 FA groups comprised of six structural FA groups (SFA, MUFA, C16 PUFA, C18 PUFA, 20:5ω3, 22:6ω3) and six storage FA groups ( SFA , MUFA , C16 PUFA , C18 PUFA , 20:5ω3 , 22:6ω3 ). The package CRAN : factoMineR in the open source software R was used for the PCA analysis using a correlation matrix (Lê et al ; R Core Team ).…”

Nutrient limitation driven dynamics of amino acids and fatty acids in coastal phytoplankton

Coastal seas like the North Sea have been subject to major changes in nutrient inputs over the last decades, resulting in shifts of limiting nutrients for phytoplankton communities. Here, we investigated the seasonal and spatial distribution and synthesis patterns of individual amino acids and distinct fatty acid groups and show how these were affected by different nutrient limitations in natural coastal phytoplankton communities. Nitrogen limited communities exhibited substantially slower synthesis of essential amino acids compared to synthesis of nonessential amino acids. In short‐term nutrient addition experiments, this trend was reversed immediately after N addition to levels found under not limiting conditions. On the contrary, phosphorus limited communities showed no such shift in amino acids. Both N and P limitation induced a shift from structural to storage fatty acids with a concurrent decrease in the synthesis of poly‐unsaturated fatty acids. Reversed effects in fatty acid synthesis after N or P addition were only apparent after 72 h, when they could be found in both fatty acid biosynthesis and concentrations. The different strategies of qualitative and quantitative regulation of different biomolecule synthesis under nutrient scarcity may have far‐reaching consequences for the phytoplankton's nutritional value. Higher trophic levels may have to cope with the loss of essential amino acids and poly‐unsaturated fatty acids in nutrient limited phytoplankton, which could induce changes in the structure of food webs.
