Abstract

The aim of this study was to evaluate the biological, physicochemical and technological related characteristics of the blue shark Prionace glauca. The sample included 128 specimens to determine their biological and technological properties and 27 specimens for their physicochemical characteristics. Biometric data of length and weight (142 to 281 cm and 10.5 to 93.0 kg for males; 153.5 to 255.0 cm and 14.5 to 80.0 kg for females), allometry index (males 3.27 and females 2.87), technological potential through different types of performance (RED: 83.9±0.03%, RESV: 67.2±0.04%, RSCV: 48.9±0.07% and RPC: 33.5±0.07%) and water retention capacity in the muscle (16.1±0.03%). Within the physicochemical characteristics, the proximal chemical composition was analysed (protein 21.8±0.23; fat 0.6±0.03; humidity 78.0±0.31; ash 1.3±0.01) and mineral composition (Cu: 2.0±0.11 mg/kg; Fe: 17.8±1.95 mg/kg; Zn: 25.8±1.76 mg/kg; Ca: 4.3±0.27 mg/100 g; Mg: 95.4±7.87 mg/100 g; Na: 716.3±24.03 mg/100 g; K: 1526.1±54.4 mg/100 g; P: 439.5±15.76 mg/100 g). There was no evidence of significant differences based on sex.
