Description The ridgeback shrimp Solenocera choprai has emerged as one of the important
commercial species in 60–100 m depth zone off Karnataka coast, India, since 1993. Studies were
conducted on S. choprai to understand its reproductive biology which can help in formulating policies
for management of the species. The diagnostic features of reproductive morphology of the species
were studied and illustrated in detail. Based on the coloration and size of the ovary and ova diameter
variations, five stages of maturity in female S. choprai were identified. The mature ova are fully yolked
with diameters between 0.24 and 0.35 mm. Size at maturity (50%) has been estimated at 54.5 and
66.5 mm total length (TL) in males and females, respectively. The gonadosomatic index (GSI) showed
an increasing trend according to the advancement of maturity of the ovary, and monthly mean GSI
showed a positive correlation with monthly percentage of spawners.
