The growth pattern showed isometric growth (slope [b] = 3.
In relations between different types of variables and/or between different measuring units, when the exponent b = 3, the weight-length relationship reflects an isometric growth (Gaspar et al.
In this study, growth of fish showed positive allometry as t-test for departure from 3 which is the value of isometric growth
showed significant difference.
Females exhibited a negative allometric growth pattern for HL but presented isometric growth
for HW and HH.
Growth rates of fish responded rapidly to the absence or reintroduction of food, whereas body composition (% wet weight) remained relatively stable owing to isometric growth in fed fish and little loss of body constituents in fasted fish, resulting in nonsignificant differences in body composition among feeding treatments.
The reason for this relative constancy among feeding treatments was two-fold: 1) isometric growth in fed fish resulted in stable body composition (%WW) throughout a range of growth rates; and 2) there was little loss of proximate body constituents in fasting fish.
The combination of isometric growth in the fed fish, and short-term food deprivation period in the fasting fish, resulted in nonsignificant differences in body composition (%WW) among the feeding treatments.
Isometric growth is assumed for Fulton's K, and differences in the weight-length relation are interpreted as an indication of stored energy.
Species presented nearly isometric growth
, with a b value of 2.
The overall coefficient b of LWR indicated a positive allometric growth (significantly, b > 3) in males, females, and in common gender, with the only exception that Guaymas males during November 1996 to June 1997 showed isometric growth (b = 3; Table 3).
The coefficient b of LWR indicated an isometric growth (b = 3) in the majority of the analyses, except for the specimens from Topolobampo (May 1999), which showed positive allometric growth (significantly, b > 3; Table 3).
On the other hand, the b coefficient during 2004 showed isometric growth in females and both genders (b = 3), but the males reflected allometry in their growth.
