Abstract:

The paper presents in parallel, a comparative study of length of digestive tube reported to the total length of body and to the standard one, as well as the activity of aspartat- and alanin-aminotransferazic from the median portion of the digestive tube at Hypophthalmichthys molitrix exemplars of one summer old, respectively four summers old. At the sapling an elongation of the digestive tube take place, this elongation being of 9.7 times (51,116 cm at one summer exemplars and 494,85 cm at the four summer ones). In early stages, the rapport between the length of the digestive tube and the total length of body is of 4,133, and the ratio between it and the standard length is 4,930. At the adult exemplars, the ratio between the length of the digestive tube and the total length of body is of 7,591, and the ratio between it and the standard length is 8,712. In what concern the intestinal transaminazic activity on remark, that the activity is higher at the exemplars of four summers. We can also conclude that the values of alanin-aminotransferase are much higher and not uniform at the individuals of both ages.
