“…The effects of dietary methionine intake on PPmet and PAmet were dependent upon the relative adequacy of the dietary methionine supply. Similar results reported that dietary methionine levels affect plasma free amino acids in several fish species such as sea bass Dicentrarchus labrax (Hidalgo et al, 1987), common carp Cyprinus carpio (Schwarz et al, 1998), and yellow perch Perca flavescens (Twibell et al, 2000). Murai Table 3 Plasma post-prandial (5 h after intubation) and post-absorptive (24 h after intubation) methionine and ammonia concentrations (nmol ml )1 ) of rainbow trout fed graded levels of dietary methionine 1 (1987) and Schuhmacher et al (1997) reported that the plasma concentrations of arginine, leucine, isoleucine, valine, phenylalanine and threonine in rainbow trout force-fed crystalline amino acids at 1% body weight (dry matter) peaked at 6-9 h and returned to the basal level at 24-32 h post-feeding.…”

This study aimed to reevaluate the dietary methionine requirement by means of the plasma methionine and ammonia concentrations in surgically modified rainbow trout, Oncorhynchus mykiss. A total of 35 rainbow trout averaging 505 ± 6.5 g (initial body weight, mean ± SD) were randomly distributed into seven groups with five fish in each group. After 48 h of food deprivation, each group was fed one of seven L-amino acid-based diets containing graded levels of methionine (0.25, 0.40, 0.50, 0.60, 0.70, 0.80 or 0.95% of diet, dry matter bases) by intubation at 1% bodyweight. Blood samples were taken at 0, 5 and 24 h after intubation. Post-prandial plasma free methionine concentrations (PPmet, 5 h after intubation) and post-absorptive plasma free methionine concentrations (PAmet, 24 h after intubation) of fish fed diets containing 0.60% or more methionine were significantly (P < 0.05) higher than those of fish fed diets containing 0.50% or less methionine. PPmet and PAmet in fish fed diets containing 0.60% or higher methionine were not significantly different except the PPmet of fish fed a diet containing 0.95% methionine. Post-prandial plasma ammonia concentrations (PPA, 5 h after intubation) of fish fed diets containing 0.70% or more methionine were significantly higher than those of fish fed diets containing 0.60% or less methionine, and PPA of fish fed diets containing 0.25% and up to 0.60% methionine were not significantly different from each other. Broken-line model analyses on PPmet, PAmet, and PPA indicated that the dietary methionine requirement of rainbow trout was between 0.59% (1.69) and 0.67% (1.91) of diets (% dietary protein bases) when the diets contained 0.5% cystine.

“…Total sulphur amino acid was 14.9 g kg −1 or 30.4 g kg −1 dietary protein. It is lower than that for sea bass, Dicentrachus labrax (44.0 g kg −1 dietary protein including 12.9 g kg −1 cystine of dry matter) (Hidalgo et al. 1987), tiger shrimp (35.0 g kg −1 dietary protein including 4.1 g kg −1 cystine of dry matter) (Millamena et al.…”

A 65-day growth trial was conducted at 19.5°C to determine the optimal dietary methionine for juvenile rockfish, Sebastes schlegeli. Semipurified diets were formulated to be isonitrogenous and isoenergetic. Fish meal was used as intact protein source and crystal amino acid was used as a part of dietary protein. Six experimental diets were formulated to contain 5. 8, 10.8, 15.8, 20.8, 25.8 and 30.8

“…The cystine-sparing value of 55% suggested in the present study with HSB is relatively high but similar to the values reported for some other ¢sh species. Harding et al (1977) found a 60% sparing value for channel cat¢sh, while Hidalgo, Alliot and Thebault (1987) reported a value of 64% for European sea bass Dicentrarchus labrax. A 50% replacement value was reported for chinook salmon Oncorhynchus tshawytscha (NRC 1993) and red drum (Go¡ & Gatlin III 2004).…”

Previous studies have indicated that the level of total sulphur amino acids (TSAA) (methionine+cystine) is most limiting in practical diet formulations for hybrid striped bass (HSB), especially if animal feedstuffs are replaced with plant feedstuffs. Reduction in costly animal feedstuffs such as fish meal, while maintaining adequate dietary levels of TSAA, may enhance the cost effectiveness of production. Therefore, this study investigated three different aspects of sulphur amino acid nutrition of HSB including: (1) the efficacy of crystalline methionine hydroxy analogue (MHA) and liquid MHA (Alimet™) relative to l‐methionine in meeting the requirement for TSAA; (2) the cystine‐sparing value for methionine; and (3) the influence of various sulphur amino acid supplements on ammonia excretion. During three separate feeding trials (2, 6 and 10 weeks in duration), juvenile HSB were fed various diets including a basal diet deficient in TSAA (0.33% or 0.51% of diet), and experimental diets supplemented on an equal‐sulphur basis with different levels of either l‐methionine, Alimet™ or crystalline MHA. Diets containing TSAA at 1% of diet and different ratios of cystine to methionine (60:40, 55:45, 50:50 and 45:55) were also fed to re‐evaluate the sparing effects of cystine on methionine. In trial 1, over the course of 10 weeks, Alimet™ was 73% as effective in promoting weight gain as l‐methionine at the same concentration while MHA was 83% as effective. After 6 weeks in trial 2, fish fed Alimet™ at 1.25% of diet displayed similar growth performance as those fed TSAA at 1.0% of diet, while weight gain of fish fed Alimet™ at 1% was only 58% of that displayed by fish fed TSAA at 1.0%. No significant differences in weight gain, feed utilization or survival were observed among fish fed diets containing various ratios of cystine to methionine, although the diet with 60:40 cystine to methionine had the lowest numerical responses. Inclusion of MHA or Alimet™ did not affect TAN excretion of HSB. These findings will aid in refining diet formulations for HSB to ensure adequate sulphur amino acid nutrition.
