In contrast, in the proximal intestine, lipase, α-amylase and TPA activities were similar among HT ST, HF R, and HT R groups (Figure 2D–F), but HT R fish had the lowest trypsin/chymotrypsin ratio, being less than 1, with trypsin-like (60 and 55 kDa, p-value < 0.05) and chymotrypsin-like (50, 25, 21, 17, and 15 kDa, p-value ˂ 0.05) activities involved in these changes (Figure 3 and Table 3). This evidence concerns the gene PLAT and hydrops fetalis.
