“…Although taurine can act as a feeding stimulant 32 , this was unlikely the cause in this study based on the observed similar feed intake among all treatments. This has similarly been suggested previously in European seabass fed taurine supplemented diets 16 , 33 . Moreover, the taurine content of T20 diet was far exceeded that of the C+ diet, indicating that the growth improvement is unrelated to prevent a taurine deficiency.…”

“…Moreover, the taurine content of T20 diet was far exceeded that of the C+ diet, indicating that the growth improvement is unrelated to prevent a taurine deficiency. On the other hand, the growth promoting effects of taurine have been linked to regulation of metabolism and improved nutrient utilization/feeding efficiency 6 , 16 .…”

“…In an earlier study, relatively low taurine levels of 2 or 3 g/kg significantly improved the growth of European seabass fry (0.8 initial mean body weight) compared to those fed diets with 0 or 1 g/kg taurine supplementation 15 . Similarly, in a low FM diet, dietary taurine supplementation of 0.5% significantly improved European seabas s juvenile growth (55 g initial mean body weight) 16 . Recently, Kotzamanis et al 17 found that taurine supplementation (1%) in a high-soy diet with moderate FM inclusion (25%) impacted significantly the organoleptic properties of seabass fillet but without substantially affecting their growth performance.…”

Plant-based proteins are increasingly being used in aquafeeds, but one of the limitations is taurine deficiency that can be especially detrimental for carnivorous fish. In this study, taurine supplementation in high plant protein diets (low fish meal, 15%) was investigated on the growth performance and fillet organoleptic characteristics of European seabass ( Dicentrarchus labrax ), juveniles (78 ± 0.4 g). Five diets were formulated to contain 0 (C−), 5 (T5), 10 (T10) or 20 (T20) added taurine (g/kg), while a control diet (C+) included two-fold higher amount of fishmeal (30%) with no taurine supplementation. Seabass fed the T20 or C+ diet showed similar growth, which was significantly higher compared to those in the C-treatment. Histological examination of the muscle, liver and intestine were similar among treatments. No effect on spoilage bacterial growth or production of total volatile basic nitrogen was observed. Taurine supplementation significantly reduced fillet drip loss, while the fillets of European seabass fed the T10 and T20 diets showed significant higher and lower hardness and adhesiveness values, respectively. Moreover, fillet chewiness was also found to be significantly higher in fish fed the T20 diet compared to C+ and C− diets. Overall, it seems that high dietary taurine supplementation acted as a growth promoter and concurrently improved significantly the postharvest quality characteristics of seabass, which may be attributed to its role in maintaining cell membrane integrity and permeability.

“…Taurine is known as a feed attractant for fishes. FI of fish can be enhanced by dietary taurine supplementation (Nguyen et al 2015;Martins et al 2018;Wei et al 2019). In the present study, FI of red seabream fed taurine-supplemented diets was higher than that of their respective SM diets.…”

Background: Taurine is a conditional essential amino acid for fish. A study was conducted to investigate the compensating effect of supplemental taurine in diets for red seabream (Pagrus major) on impaired growth performance by fish meal (FM) replacement with soybean meal (SM) at low water temperature (14.15 ± 1.95°C). Methods: A FM-based diet was considered as a high FM diet and three other experimental diets were formulated to replace FM with SM by 20, 35, or 50% (HFM, SM20, SM35, or SM50, respectively) without taurine and other four diets were formulated by adding 1% taurine to the diets (HFM-T, SM20-T, SM35-T, or SM50-T, respectively). Triplicate groups of fish (108.9 ± 1.58 g/fish) were distributed into 24 polyvinyl circular tanks (215 L) with 20 fish per tank and fed one of the diets to satiation for 20 weeks. Results: Growth performance and feed utilization of red seabream were significantly improved by the dietary taurine supplementation. SM20-T and SM35-T diets increased fish growth that are comparable to HFM diet. Feed intake, feed conversion ratio, and protein efficiency ratio of fish fed SM20-T and SM35-T diets were not significantly different from those of HFM group. Dietary taurine supplementation in each FM replaced group numerically increased innate immunity of the fish. Lysozyme and superoxide dismutase activities were significantly decreased in fish fed SM35, SM50, and SM50-T diets compared to those of fish fed HFM diet while they were not significantly lower in SM20, SM20-T, SM35, and SM35-T groups. Glutathione peroxidase activity was significantly lower in fish group fed SM50 diet while SM50-T group did not significantly lower compared to that of HFM group. The relative expression level of hepatic IGF-1 mRNA was improved in fish fed taurine-supplemented diets compared to their respective SM diets. Conclusions: Growth performance and feed utilization of red seabream can be accelerated or restored by 1% taurine supplementation when they are fed high level of SM up to 35% in diets during low water temperature season.

“…In the present experimental conditions, the protein retention was satisfactory and ranged from 27.6 -29.5%; but it has been shown that in European sea bass juveniles, a dietary taurine concentration of 1.13% can increase the protein retention up to 31% (Saleh et al, 2019). Martins et al (2018), based on a dose-response model, suggested a dietary taurine requirement of 0.47 -0.50% in European sea bass juveniles and in the present study, the taurine content in the insect inclusion diets appears limiting (0.44 -0.46%); therefore a taurine supplementation of insect inclusion diets should be considered. Carcass fatty acid composition was greatly affected by the different insect meal inclusion, because of the insect larvae fat content which affected fish oil inclusion in the diets, and thus dietary fatty acid composition.…”
