La Paz, Baja California Sur, México DOI : 10.4194/TRJFAS22332 Viewed : 1263 - Downloaded : 1325 Enzyme-pretreated rice bran is commonly used in biofloc aquaculture. In this work, crude enzymes from discards of P. vannamei were used for enzymatic pre-treatment of rice bran. P. vannamei crude enzyme extract is rich in proteases and amylases that hydrolyze casein and rice bran starch, respectively, at a rate comparable to commercial enzymes. In seawater media, P. vannamei midgut gland amylase activity is significantly higher than to commercial enzymes. Data on the use of enzymatic extracts obtained from shrimp discards is presented, contributing to future sustainable use of agriculture, aquaculture, and fisheries resources by probing an application of such by-products.
