Abstract:

An experiment was carried out for the development of freshwater image pearl culture technology has been conducted at the freshwater station, Bangladesh Fisheries Research Institute, Mymensingh for a period of eight months from March to October 2017. A total of 1200 mussels (Lamellidens marginalis) were operated with the paraffin made image. The single image was inoculated per mussel. The operated mussels were stocked in the pond and cultured through the net-bag hanging method in 1-1.5m water level of the pond @80 mussels/decimal and 30 fishes/decimal (Catla catla 6, Labeo rohita 10, Cirrhinus cirrhosus 10, Labeo calbasu 4). Organic and inorganic fertilizer was given fortnightly to the pond @ 5 kg cow-dung, 0.125 kg T.S.P. and 0.1 kg urea per decimal. During the experimental period temperature (oC), Dissolved oxygen (mg/l), Alkalinity (mg/l), pH, NH4--N (mg/l), Ca2+ (mg/l) and Phytoplankton (x103cells/L) were ranged from 26.57±0.91, 5.90±0.06, 135±5.7, 7.77±0.10, 0.05±0.02, 25±3.1 and 50.25±6.85 respectively. Survival of mussel and growth of pearl were monitored once in a month. After 8 months culture, the survival rate of operated mussels was found 61% while image pearl production rate was 46% and the layer of nacre on the paraffin made images ranged between 0.5-0.9 mm.
