南极大磷虾粉对点带石斑鱼幼鱼氟蓄积的影响
Effect of Antarctic krill powder on tissue fluoride accumulation and growth of juvenile grouper (Epinephelus malabaricus)
摘要
Abstract
The fluoride accumulation in various tissues and the growth of juvenile grouper (Epinephelus malabaricus) after fed diets supplemented with Antarctic krill powder were analyzed. The diets were supplemented with 0% (control group), 2%, 4% and 6% Antarctic krill powder, respectively and the fluoride concentrations in the experimental feeds were 145.81, 202.71, 257.53 and 317.60 mg/kg, respectively. The four diets were fed to juvenile groupers for 100 days. The results showed that the hard tissues, such as gill and vertebra, had the highest fluoride level, followed by skin (in-cluding scale) and liver, and muscle showed the lowest fluoride retention. The level of fluoride in vertebra, skin (includ-ing scale) and gill increased with feeding time and a positive correlation between dietary fluoride from krill powder and fluoride content in these tissues was observed. The fluoride content in liver increased with feeding time as well, but with no correlation between krill powder inclusion level, while there was no correlation between krill powder inclusion level and fluoride level in the muscle of juvenile groupers. Significantly higher specific growth rate was observed in groupers fed with 4% or 6% krill powder included diets compared to that in control group (P<0.05), including krill powder in the diet at certain levels could promote the growth of juvenile grouper.关键词
