“…Iron addition either as organic (up to 300 mg/kg diet) or inorganic (200 mg/kg) form was not found to improve final weight (P = 0.423) and SGR (P = 0.511) of gilthead sea bream, Sparus aurata indicating that growth cannot be used as a criterion for evaluating iron supplementation in this species. In accordance with this finding, Atlantic salmon (Andersen et al 1996(Andersen et al , 1997(Andersen et al , 1998 and red sea bream (Sakamoto and Yone 1976) showed no significant weight gain when receiving additional iron in their feeds, whereas channel catfish showed a growth retardation when given a purified diet without iron supplementation (Gatlin and Wilson 1986). These data suggested that iron present in the dietary fish meal provides the fish with iron levels sufficient for adequate growth of Sparus aurata.…”

“…The minimum dietary iron requirement has been reported to be between 60 and 100 mg/kg in Atlantic salmon, Salmo salar (Andersen et al 1996), 30 mg/kg in channel catfish, Ictalurus punctatus (Gatlin and Wilson 1986), 170 mg/kg in Japanese eel, Anguilla japonica (Nose and Arai 1979) and 150 mg/kg in red sea bream, Pagrus major (Sakamoto and Yone 1976). Deficiency of iron induces haematological suppression, reduced growth and poor feed conversion in farmed fish (Tacon 1992).…”

The comparative effects of iron-supplemented levels on growth, tissue distribution, haematology and immunology of gilthead sea bream, Sparus aurata (2 g) were investigated, using four organic (50, 100, 200, 300 mg ORG/kg diet) and one inorganic iron source (200 INOR mg/kg diet). Fish were treated for 12 weeks with the experimental diets and maintained at a water temperature of 19-22°C. Growth (final weight and specific growth rate), tissue distribution (spleen, liver and muscle), haematological parameters (red blood cells, haematocrit, haemoglobin and mean corpuscular haemoglobin concentration) and non-specific immune indexes (respiratory burst activity and antibacterial activity of serum) were analysed. No significant differences were found in growth and iron tissue distribution among the tested groups. Red blood cell counting was statistically higher in fish given 50 ORG, 100 ORG, 200 ORG and 200 INOR feeds. However, haematocrit, haemoglobin and mean corpuscular haemoglobin concentration were not significantly affected by increasing dietary iron. Fish receiving the 100 ORG diet had the best performance with respect to the respiratory burst activity and significantly higher values for antibacterial activity of serum were obtained in fish fed with the 300 ORG diet. The present findings provided no clear evidence of the optimum iron concentration. However, there was adequate indication that iron supplementation enhanced the performance of gilthead sea bream, mainly from a haematological and immunological point of view.

A 60‐day feeding trial was carried out to investigate the effect of iron on growth, body composition and digestive enzyme activities. Diets with seven levels of iron (53.9, 90.0, 115.6, 146.1, 176.0, 215.8 and 266.0 mg iron kg−1 diet) were fed to Jian carp (initial weight 11.4 ± 0.0 g). Per cent weight gain (PWG), feed efficiency (FE) and protein efficiency ratio were the lowest in fish fed the basal diet (P < 0.05). Body protein content was increased with the increasing iron levels (P < 0.05), but moisture, lipid and ash of fish were not significantly affected by dietary iron levels (P > 0.05). Activities of trypsin, lipase, α‐amylase, Na+, K+‐ATPase, alkaline phosphatase and gamma‐glutamyl transpeptidase were improved with increasing dietary iron levels. Serum iron were significantly enhanced with dietary iron levels up to 146.1 mg iron kg−1 diet, and plateaued. In conclusion, iron improved digestive enzyme activities of juvenile Jian carp and the dietary iron requirement for serum iron of juvenile Jian carp (11.4–64.0 g) was 147.4 mg iron kg−1 diet with ferrous fumarate as the iron source.

Behavioral and physiological responses of juvenile red seabream (Pagrus major) to different concentrations of ethanol were investigated. No swimming and no reaction to touching by a wooden stick was observed at 0.6% ethanol group in behavioral response, and survival rate was 100% after 5 hours of treatment. Red blood cell count, hematocrit and hemoglobin levels in plasma were not significantly different among all groups. AST activities in plasma significantly decreased as ethanol concentration increased. On the contrary, ALT activities in plasma significantly increased as ethanol concentration increased. Cortisol level in plasma was the lowest in 0.6% ethanol group. Glucose levels in plasma increased significantly when ethanol concentration increased more than 0.4%. Oxygen consumption of fish in 0.6% ethanol seawater was constantly lower than that of fish in control seawater from 2 hours after the exposure to ethanol seawater until the end of experiment.
