Processing Yields for Meat of Russian and Siberian Sturgeons Cultured in Florida, USA

ABSTRACT

Cultured Russian and Siberian sturgeons were processed and analyzed to estimate meat yields and proximate compositions. Sturgeons were approximately 18 to 24 months in age and weighed 2.3–2.6 kilograms (lower and upper intervals, 95% level of confidence) in total body weight. Dressed fillet yields in sturgeon appear to vary by species. The skinless fillet yields for Russian sturgeon and Siberian sturgeon were 26% and 32%, respectively. The proximate composition of edible portions in Russian and Siberian sturgeons may range from 70–76% moisture, 17–19% protein, 5–10% lipid, and 1–2% ash; some 116–151 calories per 100 grams of fresh, uncooked meat. However, the lipid content in Siberian sturgeon may be higher than in other sturgeon species.
