Abstract

Scarce information in available on the growth and development of Brcahionus plicatilis. This pper presents a growth model for three asiatic strains of B. plictilis: Thailand-S, Yashima-S and Nagasaki-L. The eperiments were carried out under controlled laboratory conditions. The morphometric estimations were done at regular intervals of time, along 96 hours. The growth models were made for length and width for each strain, and the residuals analysis were done to determinte the model fidelity. The results indicte correlations which go from 0.714 to 0.97 for length, nd from 0.845 to 0.924 for width. The growth pattern of B. plicatilis indicate differences whe the individual reaches the maturity. The length of the individuls of the strains studied was proportional until they reaches 30 hours of life, where the length rate goes from 153.36 to 245.64 um, depending of the strin. The width shows higher discrepncy, since the growth pattern fluctuates from 24 to 48 hours, and the rate goes from 136.59 to 175.38 um. On the other hand, the graphic analysis of residuals also indicate differences when the rotifers reach the sexual maturity.
