Sex ratio and first size gonad mature mud clams Anodontia edentula

What is it about?

The study was conducted on Tobea Island with the aim of analyzing sex ratio and first size gonad mature mud clams. Data were analyzed to determine the sex ratio and first size of gonad mature mud clams of Tobea Island by using chi-square analysis (χ2) and Spearmen-Karber Method (Udupa, 1986). The result of sex ratio analysis using chi-square based on sampling station, retrieval time and maturity level of the gonad (TKG) showed the sex ratio of male males less muddy than female gender. This is indicated by the value of chi-square count> chi-square table either based on sampling time (6,3700> 4,3027), based on observation station (6,6673> 4,3027), based on maturity level of gonad (TKG) 6.6673> 4.3027). The first size of ripe moss gonad shells, male sex reached mature gonad size of shell length of 39.62 mm, in the long shell range of 39.20 to 40.04 mm. For female gender reaches the first size of mature gonad the average length of the shell is 39.58 mm, in the long shell range of 39.21 to 39.96 mm. Mud fray on Tobea Island, the first size of true gonad for male sex reaches 39.7 mm in length and female gender reaches 38.0 mm in length.
