Carried out the collected and captured of ornamental shrimp species and strains of the genus Caridina and Neocaridina shrimp (Family Atyidae), and had collected 38 species (included 90 strains) at the least. In study, we had collected more than 79 species and strains of freshwater ornamental shrimp. Study of the intraspecies sorting and interspecies hybridization with several kinds of ornamental shrimp, included Caridina cantonensis var. CRS, Neocaridina heteropoda and N. heteropoda var. in genus Caridina and Neocaridina, respectively, and has successfully produced a total of more than 3000 hybrid offspring (hybrid F1) which has a novel form of color and pattern characteristics. And propagation the Caridina spp. which were caught from Sulawesi, Indonesia and got hybridization offspring also. Completed the feed research of various diets (Artemia salina nauplii, prawn meal, and/or mixture food) to feed broodstock and offspring, photoperiods control and sex ratio, respectively. To enhance the growth rate, survival ratio and increase the propagation frequencies, and raised 15% egg capacity and 15% survivorship with larvae, respectively. |
