Nutrition of Trout: Studies with Practical Diets.

Effects of dietary vitamin B1on growth performance, blood metabolites, body composition, intestinal enzyme activities and morphometric parameters of juvenile yellow catfish (Pelteobagrus fulvidraco)

“…Dietary vitamin B 1 deficiency signs reported in several fish species include poor appetite, reduced growth rate, increased mortality, incidence of muscle atrophy, abnormal coloration, neurological disorders and loss of equilibrium (NRC, 2011). Quantitative requirements of dietary vitamin B 1 have been reported for a number of cultured fish species including rainbow trout (Oncorhynchus mykiss) (McLaren, Keller, O'Donnell, & Elvehjem, 1947), channel catfish (Ictalurus punctatus) (Murai & Andrews, 1978), common carp (Cyprinus carpio) (Aoe et al, 1969), yellowtail kingfish (Seriola lalandi) (Shimeno, 1991), Nile tilapia (Oreochromis niloticus) (Lim & Yildirim-Aksoy, 2011), Jian carp (Huang et al, 2011), grass Carp (Ctenopharyngodon idella) (Jiang et al, 2014), Sclizothorax prenanti (Xiang, Zhou, Chen, Wu, & Zheng, 2016), Indian major carp (Cirrhinus mrigala) (Zehra & Khan, 2017) and golden pompano (Xun et al, 2019). The vitamin B 1 requirements for fish have been estimated to range from 0.5 to 15 mg/kg diet (NRC, 2011).…”

Effect of Dietary Vitamin A Supplementation on Growth and Survival of Rohu (<I>Labeo rohita</I>) Fry

“…Vitamin A is needed for growth, immune development and reproduction in animals (Blornhoff et al, 1992). The requirements of vitamin A in salmonids, rainbow trout, channel catfish and common carp have been studied by Japanese and American workers (Mclaren et al, 1947;Honje, 1965;Kitamura et al, 1967;Aoe et al, 1968;Dupree, 1970;Shimeno, 1991). Elimination of vitamin A from the diets caused typical deficiency symptoms like anorexia, retarded growth, faded body colour, haemorrhage in the fins and skin and exopthalmia (Kitamura et al, 1967).…”
