An shrimp, endemic species Indian White banded Shrimp, Caridina cf. babaulti was Slime production, selected, as the documented information about the species is scare. Thus, this DNAse and study was conducted to gather some information on its breeding behavior and Haemagglutination. life cycle until first maturity in laboratory condition.10 pairs of Indian White banded Shrimp, Caridina cf. babaulti are kept in confined system separately. The tanks are populated with common aquatic plants (Java fern Microsorum pteropus, Amazon sword Echinodorus bleherae, Anubias nana, Cryptocoryne sp., Rotala indica and mosses (java moss Taxiphyllum barbieri, Christmas moss Vesicularia montagnei) and regulated with periodic photoperiods and Co2 supply. With carefully monitored water quality parameters, the selected species was bred in confined system. It was observed that water temperature is one of the parameter that played a crucial role in influencing the spawning behavior of the species. Larvae assume a benthic lifestyle after hatching, i.e. they are miniature versions of the adults. There is no planktonic larval stage. The hatchlings of this shrimp are extremely small and grow slowly. Introduction Many freshwater shrimp from the family Indian White banded Shrimp, Caridina cf. Atyidae have been gaining popularity in the babaulti is an indigenous species. This aquarium industry over the past years species comes from pond, river, agricultural (Heerbrandt and Lin, 2006). Caridina cf. canals, mountain streams and reservoirs of babaulti is one of these atyids.

This exponential growth in the freshwater tank, it is also excellent demand needs a steady supply of stocks so maintenance crews in a cleaning the aquatic the main objectives of this research are to plants compared to other shrimp. Currently develop a standard hatchery technology for the demand for this species in the industry is fresh water ornamental shrimps and met by wild caught. producing desirable strains with the help of selective breeding and interbreeding. In Taiwan, there are 15 species of atyid from 3 genera which include Atyopsis, Materials and Methods Caridina and Neocaridina (Hung et al., 1993; Shih and Cai, 2007). Similar to Brood stocks of each species are maintained palaemonid shrimps, atyidae demonstrated in glass tank (40 x 20 x 25) supported with three types of larval development, normal, bio-chemical filter systems. Plants growth is abbreviated and completely suppressed aided with Compact Florescent lamp at a (Shokita, 1981; Shy, 1994).

As Shrimp Species for abbreviated type, larval of planktonic phase only takes few days. However, for the Indian White banded Shrimp completely suppressed type, eggs were relatively large-sized without planktonic Indian White Banded Shrimp (Caridina cf. phase since the larvae hatched in benthic babaulti var.

Water Parameters Feeding Shrimp Some of the shrimp species prefer soft, acidic water with temperatures between Caridina cf. babaulti are not picky eaters 240C – 280C; others prefer a more alkaline and will eat dead plant matter along with pH and harder water.
