Abstract

Nematopalaemon tenuipes is caught by 'dol' nets throughout the year at
Sassoon Docks and from October to May at Versova, and also by trawlnets from
March to Septemiber, from 15-40 m depth zone. The fishery shows wide annual
fluctuations. The species spawns not less than 5-6 times in its whole life span.
The females with berry in late stages migrating to slightly deeper waters, particularly
dxiring March-November, result fluctuations in sex ratio. The number of
eggs carried by a berried female of size 45-61 mm varied from 510 to 3250,
depending on its size. The estimated total mortality coefiicients in males and
females are found to be 4.70 and 3.73 at Versova while it is 4.16 and 3.36 at
