Malacostraca | Decapoda
Environment: milieu / climate zone / depth range / distribution range
Benthic; brackish; depth range 0 - 150 m (Ref. 10), usually ? - 60 m (Ref. 10). Tropical; 17°C - 38°C (Ref. 72772), preferred 24°C (Ref. 107945); 36°N - 33°S, 55°E - 154°E
Indo-Pacific: From Pakistan to Japan, the Malay Archipelago and Australia. Introduced in the Atlantic Ocean (Africa and USA). Tropical to temperate.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 4 - 4.22 cm Max length : 33.6 cm TL male/unsexed; (Ref. 8); 35 cm TL (female); max. published weight: 250.00 g (Ref. 116487)
Uniformly glabrous body; carapace with well-developed antennal and hepatic spines. Horizontal and straight hepatic carina. Rostrum armed with 7 or 8 dorsal and 3 ventral teeth. Color: body is reddish with darker bands. Brown to blue pleopods and reddish fringing setae.
Caught by pond fishing and inshore fishing. Considered a delicacy in the Philippines that in 1980, retail price was Php60 to 80 (US$8.6 to 11.5)/kg in Manila and Php50 to 70 in local areas (Ref. 10). Maximum total length (female) from Ref. 104052. Juveniles are found in estuarine environments (Ref. 8), in mangrove inlets (Ref. 121464) and mangrove vegetate area (Ref. 121475). Enters shallow brackish water or kept in ponds (Ref. 374). Found in seagrass and among shells (Ref. 121467). Pelagic, i.e. recorded in the water column (Ref. 106854). Less of a scavenger; mainly a predator of slow moving benthic macroinvertebrates like small crabs and molluscs. Also capable of capturing more mobile forms like small penaeids and fishes (Ref. 102664).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer.
