Metapenaeus dobsoni   (Miers,  1878) (Prawn)
Organism information awaits expert curation
Class: Malacostraca

Image copyrights: FAO

Maximum total length: Male 118 mm; female 130 mm.

Color: Reddish brown spots scattered on semi-transparent body; rostrum, carapace and pleural edges deep brown; antennules and antennae dotted red; double rows of reddish spots on telson.

Body tomentose in patches; rostrum double curved with 8-9 dorsal teeth and no ventral teeth and extending a little beyond the tip of the antennular peduncle; spine on basis of third pair of walking legs in male long; no exopod on the fifth pair of walking legs; petasma is quite symmetrical with two long segments interlocked forming a compressed tube with paired spouts distally; thelycum with concave median tongue and in impregnated female with two conjointed triangular pads; coxa on fifth walking leg of either side articulating with a stump in mature females. The free filament of the distomedian projections of petasma on the dorsal aspect are well in adults. Impregnated females have conjoint white pads on the thelycum. All the legs are ciliated and the chelae weak. Strong spines present on the basis of all 3 pairs of chelipeds.

Spawning appears to take place at the sea bed and the eggs float at different depth levels. Breeding appears to take place almost round the year. Each individual prawn appears to breed five times during its span of life.

The eggs measure about 0.40 mm. They hatch out as nauplii. The life history involves 3 nauplius stages, 3 protozoea stages, 3 mysis stages and 13 post-larval stages, passed in succession. The post-larvae enter the backwaters and estuaries in enormous numbers. After a period of stay in the estuarine environment the juveniles return back to the sea. They are known to stay but not beyond 80 mm length is attained in the brackish waters. Sexual maturity is attained only in the sea.
