This research was designed to determine the effects of rosemary (Rosmarinus officinalis) extract on growth, blood biochemistry, immunity, antioxidant, digestive enzymes and liver histopathology of rainbow trout. In a 40‐day diet experiment, rainbow trout was fed with the experimental diets containing 0.4, 0.7, 1 and 3 g/kg of rosemary. 0.4 and 0.7 g/kg rosemary extracts had no significant effect on all parameters studied (p > .05). The growth performance (SGR and WG) and feed utilization (FCR and FER) of the fish increased with the increase in the rate of rosemary in the feed (p < .001). Additionally, only the final weight levels were significant at the linear level (p < .05). Rosemary's 1 and 3 g/kg doses increased total protein, trypsin, amylase, lipase, superoxide dismutase (SOD), catalase (CAT), lysozyme, total immunoglobulin (IG) and white blood cell (WBC) levels when compared to control group. However, glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), total cholesterol and triglyceride levels decreased significantly (p < .001). Moreover, these doses of rosemary caused a significant reduction in steatosis of liver hepatocytes compared to the control group. In conclusion, the present study showed that rosemary may be useful in reducing the stress effects by increasing the growth, antioxidant, digestive enzymes and immunity levels, as well as reducing the rate of steatosis in the liver of rainbow trout.

“…In natural conditions, starvation is mainly associated with seasonal changes in food availability, spawning migration, the preparation of the fish body for spawning, and seasonal changes in water temperature (Miller et al 2009). In human-controlled conditions, starvation is also used in the farming of many commercially important fish species (Friedrich & Stepanowska 2001;Furné et al 2012;Karataş 2018). In the final stage of farming, fish farmers often, for a better culture effect, stop feeding the fish for a while, subjecting them to socalled depuration (Zajic et al 2013;Varju-Katona et al 2019).…”

This study examined the effect-of starvation on the chemical composition (total protein, crude fat, dry matter, ash) and the excretion of nitrogen (N) and phosphorus (P) of the Antarctic fish Notothenia coriiceps and Notothenia rossii. Starvation resulted in a decrease in lipid content in both species. In Notothenia coriiceps the body fat content decreased from 2.3% to 1.88% and in Notothenia rossii from 0.82% to 0.6%. Excretion rates of N and P were highest on the first day of starvation, then gradually decreased. Average excretion rates (in µmol N or P h −1 100 g −1) of ammonium nitrogen, organic nitrogen, reactive phosphorus, and organic phosphorus respectively were higher for N. coriiceps (8.71, 2.93, 1.09, 0.46) than N. rossii (6.28, 4.94, 0.54, 0.13). During starvation, the proportion of TON in the total excreted nitrogen was on average 43.5% for N. rossi and 24.1% for N. coriiceps, and remained at a relatively stable level. The study confirmed the natural adaptation of the studied fish to the long-term lack of food, and that the excreted loads of N and P may be a source of biogens for autotrophs and serve as a chemical signal in trophochemoreception. The inter-species differences in the excretion of N and P could be due to the differences in fish size, gonad stage of maturity, and nutritional preferences.
