AGE AND GROWTH OF STRIPED BASS 281 RESULTS Body Length-Scale Length Relationship The relationship between body length and scale length is shown in Fig-nre 1. A straight line fitted to the points by the least squares method is described by the formula Y = + , where Y is the fork length of a fish in inches, X is the enlarged scale radius measure- ment in centimeters, and is the Y axis intercept of the regi-ession line in inches. Since the smallest fish sampled were three inches long, tlie Y intercept is an artificial value significant only for back calcu- lating growth and is not necessarilj^ the body length at time of scale formation. The linear relationship between scale length and body length indicates that scale length and body length of striped bass increase proportionately at least from H inches to 34 inches. Scofield (1931) and ^lerriman (1941) also found a proportional relationship within the size ranges they studied. Growth The growth histories of all fish of ages II through IX were calcu- lated. Age I fish were not used because of the difficulty encountered in determining sex. The mean length at the end of each year of life was calculated separateh^ for each fish, and these lengths were aver-. UJ I O z UI UJ (T O z I »- ? o cr C5 FIGURE 2.
