“…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.…”

“…However, it should be noted that a plateau was found in muscle taurine concentration between the T10 and T20 treatments probably due to a saturation in its deposition. Nevertheless, this led to no significant changes to the whole-body proximate composition, as observed in cobia, Rachycentron canadum 42 , totoaba, Totoaba macdonaldi 38 and European seabass 14 , 17 , 33 .…”

“…Few previous studies have examined the effects of taurine supplementation on seabass intestine histology. Martins et al 33 observed no significant changes in the anterior intestine of seabass, when fed diet supplemented with 1% taurine. In the posterior intestine however, taurine supplementation reduced the signs of inflammation caused by the increased level of plant protein mix, and specifically resulted in an decrease in the intraepithelial lymphocytes number, improvement of nucleus position within the enterocytes and decreased enterocyte vacuolation.…”

“…For example, Kaushik et al 36 reported that 95% of FM can be replaced with various plant proteins (soybean meal, corn gluten meal and rapeseed meal) without negatively affecting their performance. In contrast, others showed depressed growth when using similar blends of various plant proteins 33 , 37 , 38 . The possible explanation for such inconsistencies might be the differences in rearing systems, raw materials, feeding methods, possible genetic differences in the fish used etc.…”

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.

“…The optimal inclusion level of dietary T for sea bass varied from 0.2%–1.0% by fish size. Juvenile sea bass (Feidantsis et al., 2014; Kotzamanis et al., 2020; Martins et al., 2019; Saleh et al., 2020) required a 1% T content in their diet, whereas Martinez et al. (2004) and Rimoldi et al.…”

The effects of either taurine (T) or sodium diformate (NDF) supplementation to a low fishmeal (FM) plant‐based diet on growth, health status, immunity and muscle cellularity of European sea bass, Dicentrarchus labrax, were investigated. Four isoproteic (44% CP) and isolipidic (17% L) diets were produced to contain 46% FM as a control diet, or 20% FM and a mixture of plant nutrients (PMX). The plant‐mix diets were either supplemented or not with 1% T or 0.3% NDF. Each diet was fed to triplicate groups of seabass (mean, 13.71 g) for 13 weeks. Fish fed the PMX diet supplemented with T or NDF was recorded to have a significantly higher feed intake, weight gain and a better feed conversion rate than other groups. The diet composition did not significantly alter the biochemical or essential amino acid composition of fish, except for the slightly reduced lipid content of T‐fed fish in comparison to the PMX‐fed fish. These supplements further enhanced blood profile, immunity response and myocytes ultrastructure relative to fish fed the PMX diet. Accordingly, these results suggest that supplementation of low‐FM/plant‐mix diet with either 1% T or 0.3% NDF can promote growth, normalize physiological conditions and improve the striated muscle structure of juvenile seabass.
