Biometric relationships for commercially important penaeid shrimp species on the east coast of the Gulf of California

Abstract

Biometric relationships were estimated for the three most important shrimp species on the coasts of the Gulf of California, Mexico. Individuals were obtained from six lagoon systems, and offshore sites along the east coast of the Gulf of California, mainly in the state of Sonora, between March and September of 2015 and 2016. A total of 25,764 individuals of Penaeus stylirostris, Penaeus vannamei and Farfantepenaeus californiensis were analyzed; the length and weight regression for the females, males and combined sexes showed a high correlation between variables. Additionally, some statistically significant differences were found in the linear length and weight relationships (P < 0.05) between sexes. This study reports the length-weight parameters for a key site of the shrimp fishery, it covers a wide range of sizes for each species and was based on the stages late inshore juvenile and offshore of the shrimp lifecycle; as such, this study provides useful information for future estimations of indispensable parameters for stock assessment analyses.

“…In this sense, the penaeid shrimp are a class of crustaceans with commercial importance in tropical and subtropical seas, reaching 1 Mt/yr of world catch (Rábago-Quiroz et al, 2019). The shrimp fishery represents one of the leading industries in Mexico, owing to the social and economic benefits involved.…”

“…Precisely, the Pacific coast in the Gulf of California (Sonora and Sinaloa, Mexico) provides over 77% of the global shrimp production in Mexico (CONAPESCA (Comisión Nacional de Acuacultura y Pesca), 2018). The three main commercial species in this region are the blue shrimp Penaeus stylirostris (Stimpson, 1871), white shrimp Penaeus vannamei (Boone, 1931), and the brown shrimp Farfantepenaeus californiensis (Holmes, 1990;Rábago-Quiroz et al, 2019). The latter constitutes the most abundant species in the fishery by weight of the offshore catch (Meraz-Sánchez et al, 2013), whereby the exoskeleton waste represents a by-product of the seafood industry that could be a potential resource for chitin and chitosan.…”
