Table 2 in Age and growth of Spanish mackerel (Scomberomorus brasiliensis) off the northeastern coast of Brazil

Table 2. Growth parameters calculated from observed lengths (OL) and back-calculated (BC) lengths, using Schnute model (1981). τ1 = first specified age; τ2 = second specified age; a = constant relative rate of relative growth rate; b = incremental relative rate of relative growth rate; y 1 = size at age τ1; y 2 = size at age τ2; z 1= relative growth rate at age τ1; z 2= relative growth rate at age τ (SE - standard error; r2 - coefficient of determination).
