Five 0.1-hectare test ponds were used to stock 100,000 seedlings with an average body weight of 1.4 g per ponds (the density of breeding was 1 million/ha). The screening rate experiment of the column-type the photoelectric facilities was carried out. The test treatment was divided into a masking rate of 0% (5-groups such as S-0), 30% (S-30), 40% (S-40), 50% (S-50), and 70% (S-70). After 12 months of breeding test results, the change of water temperature in each test under strong sunlight during the period from May to August was observed. The higher the shielding rate, the more the water temperature dropped. The average water temperature of the treatment group was lower than that of the control group (S-0) is 2.77~3.82 °C lower. The soil temperature of each test tank also has the same trend. Due to the drainage system of the photoelectric facilities, the water salinity of each test pool gradually decreased from 30psu to 15 ~ 20psu from March to September, and the salinity of the sheltered ponds (S-30 ~ S-70) are more than that of the unshielded pond (S-0) is less affected by rain. Compared with the control group, the salinity of the pool water will be 3~5psu higher. From August to September, the total ammonia-nitrogen concentration in the pools of each test pool increased abnormally (>0.5ppm), and the deaths of the samples in each test pool occurred to varying degrees. During the culture period, the growth of the control group (S-0) was lower than that of the masked treatment group (S30~S-70), indicating that moderate shading can make clam have a better growth environment.
