Use of fish silage based blended protein source for replacement of fish meal in Thai-pangas diet

A study was carried out to assess the impact of replacement of fish meal by fish silage based blended protein source in Thai-pangas (Pangasianodon hypophthalamus) diet. Five isonitrogenous experimental diets with 35% crude protein level were formulated by replacing fish meal at blended protein source consisting of one third each of fish silage, groundnut oil cake and soya bean meal The growth performance of P. hypophthalmus after feeding with different experimental diets was significantly different.
