Macrobrachium nipponense is a species of freshwater shrimp found in Asia that was first described in References[edit]. ^ Charles Fransen (). This study includes an experimental hatchery design for the prawn Macrobrachium nipponense from the brackish water of Basrah region (Al- Mashab Marsh). Experimental hatchery designed for the prawn Macrobrachium nipponense in Marine science center, Basrah, Iraq تصميم مفقس تجريبي للروبيان.

But the results of group five were 3. Macrobrachium rosenbergii De Man, [Palaemonidae].

In Cultured aquatic species fact sheets. Listing 1 – 5 of 5. Keywords Selenium toxicity Moult Macrobrachium nipponense shrimp.

After metamorphosis, PL assume a more benthic life style and begin to migrate upstream towards freshwater. Postlarvae and adults are omnivorous, eating algae, aquatic plants, molluscs, aquatic insects, worms, and other crustaceans.

The site is not able to function nipponensd without the browser having JavaScript enabled. This species lives in tropical freshwater environments influenced by adjacent brackishwater areas. Text by New, M. The study confirmed that the presence of pathological fungi Aspergillus and Penicillium have a large impact on shrimp diseases fungal infection, especially when the culture conditions are not appropriate.


Body usually greenish to brownish grey, sometimes more bluish, darker in larger specimens. Larvae swim actively tail hatcyery, ventral side uppermost.

FAO – Macrobrachium rosenbergii

Larvae mostly consume zooplankton mainly minute crustaceansvery small worms, and larval stages of other crustaceans. Males and females have different growth rates and males exhibit heterogenous individual growth HIG ; these are vitally important factors in grow-out management. The transition from rapidly growing OC to the slowly growing BC morphotype follows a “leapfrog” growth pattern.

This discovery led to larval rearing on an experimental basis. Macrobrachimu is often found in extremely turbid conditions.

Thorax contains three mcrobrachium of maxillipeds, used as mouthparts, and five pairs of pereiopods true legs. First two pairs of pereiopods chelate; each pair of chelipeds equal in size.

Code of Conduct for Responsible Fisheries. Keywords water currents Macrobrachium nipponense movement behaviour. Three distinct male morphotypes and a number of intermediary types exist: Second chelipeds bear numerous spinules; robust; slender; may mcrobrachium excessively long; mobile finger covered with dense, though rather short pubescence. Production in India and Thailand expanded by more than 50 percent per year between and ; this trend is expected to continue.


While production of the out ponds cage two in mud and fiberglass ponds were estimated between 4, larvae and 2, Postlarvae. From PL macrobachium prawns swim forwards, dorsal side uppermost.

Blackwell Science, Oxford, England. Rostrum long, normally reaching beyond antennal scale, slender and somewhat sigmoid; distal part curved hwtchery upward; dorsal and ventral teeth. As a conclusion of the observed results this prawn seems to be a nnipponense feeding species. From metamorphosis onwards prawns can also walk, not only on the sub-stratum but also over damp areas including stones by river edges, up vertical surfaces small waterfalls, weirs, etc.

Antennae often blue; chelipeds blue or orange. Since then, giant river prawn culture has developed in every continent, particularly in Asia and the Americas. Eyes stalked, except in first larval stage. Abstract The present study showed the effect of water currents 0. The production capacity was 53, Zoea larvae, 32, Postlarvae.
