- In the experment results of different substrates of cupped oyster , the best is plankton net group is 15 grains /cm2, followed by oyster shell fragments 12 grains /cm2, followed by polylactic acid grains 0.6 grains /cm2 and fish scales 0.5 grains /cm2.
- The comparison results of cupped oyster culture experiment showed that the growth of shell length was best in the control group, which was increased by 144%, followed by the upwell type 1/L group 140%, 2/L group 132%, 3/L group and channel type 3/L 127% in the group, 117% in the channel 1/L group and 116% in the 2/L group. In weight growth rate, the control group also increased by 1448%, followed by the upwell 1/L group with 1123%, 1070% of the 2/L group, 1067% of the channel 3/L group, 1028% of the channel 2/L group, 1009% of the upwell 3/L group and 936% of the channel 1/L group. One time the economic benefits of coupped oyster seedlings produced in 300 m2 of green energy greenhouse are evaluated. One time (60 days) has an economic benefit of about 3 million dollars and an annual net overflow of about 18 million dollars.
