Description :
The kharland is a saline land in which affected with sea water. It is found in the Konkan region of Maharashtra, India. The cage culture of Macrobrachium rosenbergii was carried out in the kharland ponds, located in the campus of college of Fisheries, Shirgaon, Ratnagiri during August, 2001 to October, 2001. For the cage culture purpose, the cages were prepared by nylon net and PVC pipes, stocked in the kharland ponds. Each pond is a small and rectangular shaped water body with an area of 0.045 ha.(30 m x 15 m)and a depth of 1.5 meter. Seed of Macrobrachium rosenbergii was purchased from the Marine Biological Research Station, Pethkilla, Ratnagiri and stocked in the kharland ponds. The experiment was done in two phases, viz., Nursery Phase and Culture Phase. The period of each phase was 45 days. Better growth and survival was recorded in both the phases. There was no significant difference in length and weight attained by the prawns in cages (P<0.05). The cage culture of Macrobrachium rosenbergii was successful in the kharland ponds but requires more practices.
