Length at first maturity / Taille / Poids / Âge
Maturity: Lm ?, range 80 - ? cm
Max length : 185 cm TL mâle / non sexé; (Ref. 44724); 156.0 cm TL (female); common length : 60.0 cm TL mâle / non sexé; (Ref. 9258); common length :100 cm TL (female); poids max. publié: 25.0 kg (Ref. 11115)
Commonly found in lakes and rivers (Ref. 9258). Inhabits stony rivers (Ref. 9072). Migrates to the sea to breed. Oviparous (Ref. 205). Marketed fresh, smoked and frozen; eaten fried and broiled (Ref. 9988). Reports of reaching up to 2 meters and 50 kilograms are rare and more common historically; in recent times, only a few exceed 120 cm TL (Ref. 82796).
