When the consistency of Brom ochlorohydantoin is 0.3×10~(-6),0.6×10~(-6) and 1.5×10~(-6),four experimental fishes(Ctenopharymgodon idellus,Hypophthalmichthys molitrix,Anguilla japonicus,Xiphophorus helleri) are safe;
溴氯海因浓度为0.3×10-6,0.6×10-6和1.5×10-6时,4种试验鱼(草鱼(C tenopharyngodon idellus),白鲢(Hypophthalm ichthys m olitrix),日本鳗(Anguilla japonicus),红剑尾鱼(Xiphophorus helleri))是安全的;
In the lipid of gonad,the contents of n-3 PUFA and n-3 HUFA in fish fed 1.12% n-3 HUFA diet,and DHA in fish fed 1.12%,2.40% and 5.85% n-3 HUFA diets were significantly lower than those in the trash fish group(P<0.05).
The results showed that at the end of the experiment both survival and weight gain rate were similar in fish fed different diets, and the mean values were 92.50~100.00% and 96.21~106.21%, respectively.
The 16-week feeding trial showed that the morbidities and mortalities in the fish fed the diets with peroxide values of 3.6,69.5,145.3 and 263.6 mEq O_2/kg oil were 0,16.7%,40.0%,76.7% and 0,10.0%,23.3%,40.0%,respectively.
The highest growth rate and lowest hepatosomatic index were obtained in fish fed a diet containing an EPA/DHA ration of 1/2.The dietary fatty acid compositon seemed have no effect on the fatty acid compositon in the polar and nonpolar lipid from muscle and liver.
In the fish fed the formulated feed varying from 30% to 38% in dietary protein, the protein in muscles increased from 60.95% to 69.86%, and the lipid decreased from 29.27% to 21.69%, whereas the fish fed the formulated feed containing 46% dietary protein had a decrease in protein (64.35%) and an increase in lipid (26.06%) levels in muscles.
Results showed that the relative growth ratio and survival ratio of the fish fed on medium lipid diets (8%) or high ether extract diets (12%) were significantly lower than those of the fish fed on low ether extract diets (4%) (p >amp;lt; 0.05).
There was a positive correlation between the ether extract contents in hepatopancreas of fish and the ether extract contents of diets.
The main pathological change in ill fish was fatty liver disease.
The pathological severity and serious level of fatty liver disease in the tested fish positively correlated with the contents of the ether extract, but not with those of protein, in test diets.
Foamy viruses (FVs) have broad cellular tropism infecting vertebrates from fish to human being, which indicates that Env protein has a high capability for membrane fusion.
Inhibitory Effect of an Antimicrobial Preparation from Lipids of Marine Fishes on Tissue and Microbial Enzymes
In a variable light regime, the fishes grow at a higher rate, have decreased oxygen and food requirements, improve the utilization of consumed food for growth, and decrease the oxygen expenditure per increment of unit body mass.
As a result, the maximum age of Salmo fishes hosting the mussel can be as high as 13 years.
Within the Teleostei, loach MLC1 had the highest homology with other Cyprinidae, and least with Salmonidae fishes.
