Development of Enzymes and In Vitro Digestibility during Metamorphosis and Molting of Blue Swimming Crab (Portunus pelagicus)

Figure 4

In vitro protein digestibility (μmol DL-alanine equivalent g⁻¹ of dried raw material trypsin activity⁻¹) of different feed raw materials using crude enzyme extracts from different stages of cultured P. pelagicus (zoea, Z1–Z4; megalopa, Mp; first crab, C; adult stages, 1M–4M) and wild adult P. pelagicus. The bars with different superscripts are significantly different ().
