As soon as the colour of the eggs starts changing from bright orange to light grey, it is advisable to add enough seawater gradually to the tank to raise the concentration to about 5 percent seawater.

Antero-ventral margins of carapace produced further forward to form the pterygostomian spines. The green water technique is often used for marine shrimp larval culture because it provides less direct light and nitrogen waste Nunes et al. L – O Second stage: Growth curves for Macrobrachium rosenbergii in semi-intensive culture in Brazil. The males keep on growing to about g each. In this article the length growth curves of Macrobrachium rosenbergii De Man, held in different population densities were analysed.
They are attracted by light, but direct sunlight and other strong lights are avoided.

Under natural conditions, larvae may hatch in both brackish and fresh water areas, but those that hatch in fresh water would soon be carried by the flow of water to the estuaries, and those that failed to reach brackish waters within 4 to 5 days would be unable to survive.

Journal of the World Aquaculture Society Since prawns are very sensitive to chemical insecticides, stocking of prawns is not recommended for padi-fields where such insecticides are normally applied. Indonesian production is reported in for the first time. This study assesses larval survival for different combinations of stocking density and feeding from larvae cultivated in green water.
Four cleavage furrows appear when the third nuclear division is almost completed; they start from four subequidistant points on the surface and rosenbfrgii rapidly almost at right angles to each other to form four quadrants, or blastomeres, whose apexes become joined by a median furrow; each of the four quadrants contains two nuclei. Some hatcheries are integrated with nursery and grow-out facilities.
Apart from the kinds and quantities of fertilizers normally used macrobracjium padi cultivation, additional application of fertilizer is usually not required, and no supplemental feed is needed.
For the sake of convenience, these eight stages are described below as the eight larval stages. This development spawned the first commercial farms in Hawaii and elsewhere.

Under natural conditions, the juveniles migrate to fresh water and adult females release their larvae in the upper parts of estuaries.
Exopod of maxilla with 7 long plumose setae. During the seventh day, the optic rudiments develop into a pair of large oval masses, forming the optic vescicles. First two pairs of pereiopods chelate; each pair of chelipeds equal in cultivvo.
