Protein hydrolysate from cattle residues can be included in diets for Nile tilapia ( Oreochromis niloticus ) fingerlings

Abstract

With the expansion of aquaculture production, the cultivation of fast-growing species, with good feed conversion and tolerance to adverse cultivation situations, has become widespread. In addition to these characteristics, Nile tilapia (Oreochromis niloticus) has great acceptance in the consumer market, due to the organoleptic properties of its meat and the absence of 'Y'-shaped intramuscular bones, currently being the third most-produced fish species worldwide, with 4,525,000 tons produced in 2018, representing 8.3% of all world fish production (FAO, 2020;Suresh & Bhujel, 2012).
