Biometric relationships of white shrimp Litopenaeus vannamei Boone 1931 (Decapoda, Penaeidae) for the Gulf of Tehuantepec, Mexico

Abstract

This study describes biometric relationships of white shrimp L. vannamei for the Gulf of Tehuantepec. We examined 5,104 records of totallength and weights, and 4,890 records of abdominallength and weight records. The specimens camefrom artisanal catches in the lagoon systems and the high sea technical fishery, from different sampling campaigns. The established relationships were total length-total weight, total length-abdominal weight, abdominal length-total weight, abdominal lengthabdominal weight, total length-abdominal length, abdominal length- total length, total weight-abdominal weight, and abdominal weight-total weight. The αand β parameters were estimated through potential and linear functions, depending on the established type relationship.
