The present study of the length-weight relationship and condition factors of seven shrimp species on the southeast coast of Tamil Nadu between July (2022) and February (2023) also estimated the coefficient of determination (r2).
For shrimp species, the length-weight relationship shows some species have significant positive coefficients which have a determination by (r2>0.5) like Penaeus indicus, Penaeus mergiuensis, Penaeus canaliculatus, Penaeus latisulcatus, Penaeus monodon, some species have shown negative as (r2>0.5) value like Penaeus japonicas and Penaeus semisulcatus.
All shrimp species have heterogeneity evident in intercept (a). The growth exponent (b) varied between 0.278 and 2.289 and it significantly (p=0.05) deviated from the value of <3 which denoted negative allometric growth for all Penaeus shrimp species.
