Description 589-600
This
study was undertaken of natural population of Venerupis aurea and Ruditapes
decussatus from three sites in Timsah
Lake, Suez Canal, Egypt.
Population structures, growth characteristic, age and gametogenic cycle of
these clams were studied. Dominant size was 20.1-25 mm for both genera. Age
ranged from the first to the fifth with the dominance of the third age group in
Venerupis aurea. Whereas it reached to the sixth age group in Ruditapes
decussatus with the dominance of the fourth. The male/female ratio was
1.02: 1 and 1.25:1 for Venerupis aurea and Ruditapes decussatus respectively.
Five stages of gonadal development were observed and seasonal gonadal changes
were registered. Comparisons of the present study with that previously obtained
on the same genera were reported.
