“…Selenium deposition in liver increased linearly with increasing levels of dietary selenium. This linear increase has been described in multiple fish species, regardless of the source of Se, including Atlantic salmon (Berntssen et al, ), black sea bream (Wang et al, ), channel catfish (Wang & Lovell, ), cobia (Liu et al, ), gibel carp (Han et al, ), hybrid striped bass (Cotter, Craig, & Mclean, ), malabar grouper (Lin, ), Nile tilapia ( Oreochromis niloticus , Lee, Nambi, Won, Katya, & Bai, ), olive flounder ( Paralichthys olivaceus , Lee, Lee, Bai, & Hung, ), rainbow trout (Hilton & Hodson, ; Wang et al, ) and white sturgeon (Tashjian et al, ). Dietary Se may also affect the deposition of other minerals in liver, such as copper, which follows a positive correlation with Se deposition in Atlantic salmon (Poppe, Håstein, Frøslie, Koppang, & Norheim, ) or rainbow trout (Hilton & Hodson, ).…”

“…In agreement, in vitro studies with rainbow trout hepatocytes show an elevation of gpx activity when exposed to increased levels of selenomethionine (Misra et al, ). However, only the increase from low dietary Se levels in fish larvae (Penglase et al, ) or high levels in juveniles (Pacitti et al, ; Penglase et al, ; Wang et al, ; Zee, Patterson, Gagnon, et al, ) up‐regulates gpx expression. In larval gilthead sea bream, dietary increase from 1.73 to 6.41 mg Se/kg as selenium yeast is associated with best growth and significantly down‐regulates gpx expression, whereas further increase in Se only tends to up‐regulate this gene (Saleh et al, ).…”

Substitution of marine ingredients (FM‐FO) by plant protein and oil sources can modify selenium (Se) levels in feeds. Se plays an important role in the antioxidative defence by forming part of selenoproteins. Se requirements of gilthead sea bream are not accurately determined; therefore, this study was conducted to define Se supplementation levels in low FM‐FO practical diets for sea bream fingerlings. A plant‐based diet containing 0.45 mg Se/kg diet was used as the basal diet. Four other diets were supplemented to contain 0.68, 0.86, 1.00 or 1.70 mg Se/kg diet, supplied as sodium selenite. Sea bream, weighing 12.6 ± 1.4 g, were distributed in triplicate groups per diet and fed for 42 days. Se supplementation up to 1.00 mg Se/kg significantly improved the growth of sea bream, whereas further increase up to 1.70 mg Se/kg diet reduced growth. The results of this study suggest that the optimum dietary levels of sodium selenite in diets with low FM‐FO with basal levels of 0.45 mg Se/kg are around 0.94 mg Se/kg to promote growth of gilthead sea bream juveniles. On the contrary, dietary levels of 1.70 mg Se/kg were found to be excessive and caused growth reduction, increased catalase expression and hydropic degeneration in the liver.

“…This element has many functions including removing lipid peroxides, protecting the integrity of immune system, regulating thyroid hormones and promoting better growth performance (Lee et al, ; Wang et al, ; Wang & Wang, ). Selenium influences an organism's health by affecting the metabolism or activity of selenoprotein (Khan, Zuberi, Fernandes, Ullah, & Sarwar, ; Lu & Holmgren, ; Wang et al, ). Selenoprotein, a protein containing Se as an important component, plays an important role in the normal growth of animals (Wang et al, ; Wrobel, Power, & Toborek, ).…”

No studies have been focused on the inclusion of organic selenium in formulated feed of abalone when organic minerals are accepted by aquaculture feed industry. This experiment evaluated the effect of organic selenium on the growth, antioxidation, immunity and gene expressions of selenoproteins in abalone. Graded levels of organic selenium were included to the basal diet at 0.00, 0.15, 0.30 and 0.60 ppm providing 157.83, 322.51, 437.59 and 596.59 ug/kg of selenium in the diet. Accordingly, the diets were named as Se-0.00, Se-0.15, Se-0.30 and Se-0.60 respectively. Results had shown that survival rate, weight gain rate and shell length increase rate were lowest for Se-0.60 group (p < 0.05). The concentration of selenium in the whole body generally increased with increasing level of dietary organic selenium (p < 0.05). The enzyme activities related to antioxidation increased initially with low levels of dietary selenium and decreased with higher levels, with the highest value in Se-0.30 group (p < 0.05). The enzyme activities of immunity increased with the addition of dietary selenium. With the increase of dietary selenium, Myostain expression decreased initially and increased afterwards, with lowest value for Se-0.30 group (p < 0.05). However, the expressions of other genes related to growth, antioxidation and selenoproteins firstly increased and then decreased, with the highest value recorded for Se-0.15 group. In conclusion, the inclusion rate of 0.15 -0.30 ppm Se in diet could promote growth, antioxidation, immunity and gene expressions of selenoproteins in abalone; however, excess selenium with 0.60 ppm inclusion lever in diet had toxic effects.
