Figure 5 in Seminiferous tubule number and surface: validation of objective parameters to estimate reproduction activity of male European anchovy (Engraulis encrasicolus, L.)

Figure 5. – Mean values of STM and STA in Engraulis encrasicolus from October 2007 to May 2008. 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 (values indicate the monthly average number of repetitions).
