Abstract
The Polychaete Pseudonereis anomala Gravier, 1902 had been recorded firstly in the Barge
Canal. From all 792 collected individuals the sex ratio was 1.6 male: 1 female. Pseudonereis
anomala has two spawning seasons, the first was reported in early spring (March and April) and
the second in late summer and early autumn (August and late September) at water temperature
(19-30 ºC).The mature oocytes diameter ranged between 170 to 207.9 μm.
