At that time, the pond culture of freshwater carps under low stocking densities was the major form of aquaculture practiced, and most of the common diseases seen in small ponds were basically under control, a result of research on fish pathology and the use of traditional health management strategies and control measures which were well established.
According to the One-Way ANOVA, the results showed that the salinity had a significant effect on the drug concentration of plasma (p < 0.01), musle (p < 0.01), liver (p < 0.01) and kidney (p < 0.01) in the all sampling time points between the brackish water grass carps and the freshwater grass carps.
In the present study, the datas of plasma and tissues drug concentration was showed that the salinity had a significant effect on the drug concentration of plasma (p < 0.01), muscle (p < 0.01), liver (p < 0.01) and kidney (p < 0.01) in the all sampling time points between the brackish water grass carps and the freshwater grass carps.
Protein hydrolysate was prepared from visceral waste proteins of an Indian freshwater major carp, Catla catla.
Protein hydrolysate was prepared from visceral waste proteins of Catla (Catla catla), an Indian freshwater major carp.
Compare to the freshwater grass carps, the brackish water grass carps have more rapidly drug clearance and shorter elimination half-lives when the grass carp cultured in the low salinity water.
These findings indicate that water environment affects the tissue distribution and elimination of PZQ in grass carps, the elimination in brackish water grass carps is more rapid than that in fresh water grass carps and tissue concentrations of brackish water grass carps are lower than that in freshwater grass carps after orally administrating the same dosage at the same water temperature.
Further, tissue concentrations of brackish water grass carps are lower than that in freshwater grass carps, after orally administrating the same dosage at the same water temperature.
These findings indicated that PZQ elimination in brackish water grass carps was more rapid than that in freshwater grass carps.
The plasma and tissue PZQ elimination half-lives (t1/2β) in brackish water grass carps were shorter than that in the freshwater grass carps (Table 1).
