Figure 3 in Seminiferous tubule number and surface: validation of objective parameters to estimate reproduction activity of male European anchovy (Engraulis encrasicolus, L.)

Figure 3. – Mean values of STM and STA in Engraulis encrasicolus according to the gonad maturity stages (I to V). A: Seminiferous tubules number (counted under 10x magnification). B: Seminiferous tubules area (mm2) (measured on the basis of 25 tubules). Data are represented as Mean ± SEM. Different letters indicate significant differences (ANOVA with Tukey's post-hoc test, p <0.05).
