Use of viscera extract from hybrid catfish (Clarias macrocephalus × Clarias gariepinus) for the production of protein hydrolysate from toothed ponyfish (Gazza minuta) muscle

► Proteinase activity of viscera extract from hybrid catfish was investigated. ► Toothed ponyfish hydrolysates could be produced by catfish viscera extract. ► It was a good source of desirable peptides and amino acids.
