Evaluation of pyloric caeca histometry in rainbow trout along the first year of development.

Trout Weight	N.	Pyloric Caeca (µm)	Enterocytes Supranuclear Vacuolization (SNV)
50 g	5	380.91 a ± 35.85	−
150 g	5	719.50 b ± 32.45	−
500 g	5	1011.50 c ± 18.14	+

Values are expressed as mean ± SD. ^a–c Different superscripts in the same column indicate significant differences (p < 0.05) determined by one-way ANOVA (animal weight independent variable). The presence or the absence of enterocytes supranuclear vacuolization are indicated with “+” or “−” respectively.
