“…Similar results have been reported by Han et al (2014) for olive flounder. High levels of cholesterol often indicate physiological disorders of fish (Eslamloo et al 2012). In the present study, plasma cholesterol levels were high in fish fed the control diet.…”

The objective of this study was to examine the effect of dietary supplementation of taurine for juvenile olive flounder (Paralichthys olivaceus) at low water temperature (16.4 ± 0.36°C). Fish meal (FM)-based diet was used as the control diet. Four other experimental diets were prepared by adding taurine to FM-based diet at 0.25, 0.50, 1.00, and 1. 50% (T1, T2, T3, and T4, respectively). Each experimental diet was fed to triplicate groups of fish (initial mean body weight, 19.5 g) for 10 weeks. At the end of the feeding trial, growth performance and feed utilization, hematological parameters, non-specific immune responses, whole-body proximate composition, and liver mRNA expression of insulin-like growth factor-1 (IGF-1) were investigated. Feed conversion ratio was significantly reduced while protein efficiency ratio was significantly increased in taurine-supplemented groups. Hematocrit and hemoglobin were also significantly increased while plasma cholesterol levels were decreased in taurine-supplemented groups than those in the control group. Nitroblue-tetrazolium, myeloperoxidase and lysozyme activities, and plasma immunoglobulin level were significantly increased by taurine supplementation. These results suggest that dietary taurine supplementation is effective in improving growth performances, feed utilization, and innate immunity of olive flounder in low water temperature season.

In this study, the effect of short-term starvation (0, 1 and 2 weeks) on biochemical parameters and nonspecific immune response of tinfoil barb (Barbonymus schwanenfeldii) was investigated. Fish in three different groups were deprived of feed for 0 (control), 1 (S 1 ) and 2 (S 2 ) weeks, respectively. At the end of the experiment, blood samples were collected for biochemical and immunological analyses. The results indicated that plasma glucose, cholesterol and peroxidase levels and haemolytic complement activity were significantly lower in starved fish for 2 weeks than those in fed fish and in starved fish for 1 week. Plasma lysozyme activity significantly changed in different starvation periods in all treatment groups. However, no significant effect was observed on plasma antiprotease activity. There were significant differences between the control and the food-deprived groups in plasma triglyceride levels. Starvation increased plasma total protein, albumin and globulin in the deprived groups compared with the control group. The results of this study showed significant changes in nonspecific immune parameters, plasma glucose levels and other metabolites in this species after feed deprivation that are indicative of the relationship between starvation effects and the extension of starvation period.

“…Depending upon the fish species and the study, it has been shown that dietary administration of b-glucan enhances or does not alter lysozyme or complement activities (Kiron 2012). For other kinds of supplementation the lysozyme or complement activities are also variable in Siberian sturgeon (Eslamloo et al 2012;Geraylou et al 2012Geraylou et al , 2013Kolman 2001;Xie et al 2006). In our study, both lysozyme and complement activities are unmodified by dietary supplementation.…”
