“…A higher level of protein resulted in increased vitamin B 6 requirement when hybrid tilapia were fed a high-protein diet compared to a low-protein diet (16.5 mg kg À1 versus 1.7 mg kg À1 ) (Shiau & Hsieh 1997). This is consistent with a trial with Nile tilapia (Oreochromis niloticus) showing a requirement for maximal growth of 11 mg kg À1 with a dietary protein level of 380 g kg À1 (Teixeira et al 2012). …”

The present review presents data on fish requirement for B vitamins and describes their mechanism of action. Both general deficiency symptoms such as reduced growth and appetite, and more specific deficiency signs, for example abnormal swimming activity due to thiamine deficiency, are included. The rationale is to elucidate the need to establish B vitamin recommendations for fish fed practical diets where the major part consists of plant ingredients. Most requirement studies referred to were performed with semi-purified diets with relatively low growth rate compared to the growth potential of the fish obtained with practical diets. Further, when giving salmon a plant-based diet (70% plant ingredients), substantial lowered growth was obtained even when the diet was added vitamins according to the newest established requirements. New recommendations for B vitamin addition in plant-based diets are therefore urgent. Few requirement studies exist and often with lack of doseresponse data. For riboflavin and biotin, this review includes a meta-analysis to support earlier requirement estimates. Too few data existed on the others to perform any meta-analyses that made sense. Based on literature data, meta-analyses, new experiments utilizing doseresponse designs and identification of metabolic biomarkers, this review suggests new B vitamin recommendations for fish fed plant-based diets.

“…As to haematological profile, all parameters for fish fed OPF diets, remained within the normal range for healthy Nile tilapia according to Falcon, Barros, Pezzato, Sampaio, and Hisano (), Barros, Ranzani‐Paiva, Pezzato, Falcon, and Guimarães (), Teixeira et al (), and Damasceno et al (), which were determined in similar experimental conditions and, also by Hrubec and Smith (). On the other hand, only fish fed the control diet (0 OPF) presented a significant decrease on RBC, with a reduction up to 21.8% after HDOIS.…”

“…Afterward, a different group of fish, six per treatment, was euthanized (benzocaine, 300 mg/L) and liver was collected to analyse the activity of antioxidant enzymes. After three days of HDOIS (Damasceno et al, ; Teixeira et al, ), the same haematological profile and the antioxidant enzyme activity were also determined, but in different fish groups (six fish/treatment). The data obtained before and after HDOIS were compared, in order to analyse fish capacity to cope with the stress.…”

Orange peel fragment improves antioxidant capacity and haematological profile of Nile tilapia subjected to heat/dissolved oxygen‐induced stress

et al. 2018

This study evaluated the ability of orange peel fragment (OPF) to act as a functional feedstuff, influencing growth, haematological profile, and antioxidant enzyme activity of Nile tilapia subjected heat/dissolved oxygen-induced stress (HDOIS). A group of 440 male Nile tilapia (31.7 g ± 0.34) was randomly distributed in 40 250-L aquaria (11 fish/tank) and fed five practical diets with graded levels of OPF at 0%, 0.2%, 0.4%, 0.6%, and 0.8% for 70 days. The diets were formulated to contain 30% crude protein and 18 MJ/kg crude energy. After the feeding period, growth performance was evaluated and six fish per treatment were sampled for haematological profile and antioxidant enzyme activity, before and after HDOIS. Then, fish were subjected to HDOIS (32°C/2.3 mg/L dissolved oxygen) for three days and the same haematological profile and antioxidant enzyme activity were determined. There was no effect of OPF on the haematological profile, either before or after HDOIS. The polynomial regression model was used to express the relationship between antioxidant enzymes activity and OPF supplementation level. The maximum activity of superoxide dismutase, catalase, and glutathione peroxidase was reached at 0.66%, 0.63%, and 0.68% of OPF respectively. Results of the present study suggest that a dietary supplementation level of 0.63%-0.68% of orange peel fragment was appropriate to maintain Nile tilapia haematological profile and improve its antioxidant capacity under HDOIS.

“…This is similar to the results of Saravanan et al (2011) who found that fish exposed to lindane had increased plasma protein levels relative to control. In addition, Teixeira et al (2012) found a significant change in the total plasma protein of tilapias stressed by heat. Lysozyme is a nonspecific immune modulator against toxic substances and pathogen infections, and its activity increases in fish blood after infection or exposure to foreign substances (Alexander and Ingram, 1992).…”
