Samples were taken between December 1999 andMarch 2000. Length (PL), width (PW), and height (PH) of prosome and length (UL) and width (UW) ofurosome were measured in each female and subsequently, the following ratios PL/PW, PL/PH, PW/PH,PL/UL and UL/UW were determined. Volumes for M. albidus and C. vicinus females were estimatedfollowing the morphometric method Regression tests were conducted for both species between volume andprosome length or width. Regression lines were compared through covariance analysis. PL/UL was the bestratio for separating one species from the other. Average individual volume and standard error estimated forM. albidus and C. vicinus were 0.0063 (±0.001) mm3 and 0.0049 (± 0.001) mm3 respectively. Differencesbetween both copepods morphometric variable and rate values were observed. Measured size and volumevalues increased in March and June compared with December. According to R2 values of regression lines,prosome width and prosome length were good volume predictors on different dates for M. albidus and C.vicinus. Differences in slopes and mean variances found between regression lines demonstrated variabilityaccording to different months.
