Comment:
Gonad stage: Percentage (from a montly sample of 20 clams) of male and female clams classified into four gonad stages: early mature; advanced maturity; mature; early regresion, final regresion. Classification was made after histological examination of alcohol-formol-acetic acid-preserved gonad samples. Tissue embedded in paraplast wax after dehydration, sectioned at 5 µm and stained with ARTETA trichromic stain before examination. Data points extracted from figure 21
