Abstract:

The various parts of the body of the Atlantic sailfish, I. albicans, g different rates throughout their life history so that the ratio of one dimension to another is not constant. The selection over the extremes of the range or mor phometric characters for comparison of geographic ally remote stocks must be considered from many standpoints with special attention to sampling selectivity and growth related character changes. Statistical analysis of allometric growth fea tures typically has been restricted to values near the mean body length. Schaefer 1952 cau tioned that a particular equation thus obtained may not be representative when the range is extended. Author
