A rate of protein in the cestode Bothriocephalus acheilognathi and in their hosts, capps of the age "0+", in conditions of experimental feeding and starvation

Kurovskaya, L.Ya.
Experiments were carried out on carps of the age 0+ captured in the Kiev region (fish farm "Nivka"). Morpho-phisiological characters in infected with the cestode Bothriocephalus acheilognathi differ from ones of noninfected fishes both in conditions of starvation and of feeding by standard granular combine food. The reliable decrease of absolute mass of the body and some internal organs in fishes was stated in case of starvation during 20 and 30 days. The reliable decrease of absolute and relative content of protein in a liver and a kidney of infected fishes, which starvated 10 and 20 days, was observed. During all time of experiments (30 days of feeding and starvation) the relative content of protein in immature B. acheilognathi taken out of carps, which starvated during 30 days, was higher than in adult cestodes. The high rate of relative content of protein was observed in adult cestodes taken from carps, which starvated during 30 days, and the high rate of absolute content of protein was observed in all ages of cestodes, which fed together with fishes during 30 days. A starvation and a feeding of carps infected with bothriocephalus do not change the dynamics of protein rate in cestode tissue in dependance of their number in intestines. The relative content of protein in anterior region of the bothriocephalus body is higher than in posterior region of it. In case of 20 days starvation of fishes infected with cestodes the rate of protein in different regions of the bothriocephalus body increased 2.8 times in comparison with cestodes taken from fishes, which starvated 10 days
