魚塭結合模擬浮動型太陽光電設施之青蟹養殖試驗,於田間土池放養青蟹稚蟹,重量41.3±11.6 g,甲殼寬5.6±0.5 cm,經放養約152天,設置模擬光電浮筏池 (試驗組) 青蟹重量為567.3±110.4 g,甲殼寬14.3±1.5 cm;無模擬光電浮筏池(對照組) 重量468.7±103.2 g,甲殼寬12.4±1.1 cm。設置模擬浮筏光電池(試驗組)總育成率為48.4%,無模擬光電浮筏池(對照組)總育成率為34.8%。試驗期間水質變化,試驗初期試驗組水中溶氧低於5ppm,對照組則維持在5 ppm以上。試驗期間試驗組池水溫度略低於對照組,兩組氨(NH4+ )多維持在0 ppm,亞硝酸(NO2- )在夏7-8月因連續多天降雨後達0.4 ppm,經水質管理NO2- 逐漸漸低。鹽度變化則隨著夏季雨季期間降雨變化,鹽度由32 psu逐步降低至17 psu,而後鹽度逐漸回升,但試驗組池水鹽度都略高於對照組。

研究報告摘要(英)


The test results showed that the weight of mud crabs (Scylla spp.) was 41.3±11.6 g and the carapace width was 5.6±0.5 cm. The juvenile crabs were cultured for 152 days. The photoelectric floating raft pond (Experimental group, EG ) mud crab was cultivationed weigh 567.3±110.4 g and the carapace width was 14.3±1.5 cm. ; The non-photoelectric floating raft pool (Control group, CG) mud crab weight was 468.7±103.2 g, and the carapace width was 12.4±1.1 cm.

The total growth rate of floating raft photovoltaic cells (EG ) was 48.4 %, and the total growth rate of non-photoelectric floating raft ponds (CG) was 34.8 %. At the beginning of the experiment, the dissolved oxygen in the water in the experiment group was lower than 5 ppm, while the control group maintained above 5 ppm.

During the experiment, the pool water temperature of the experimental group was slightly lower than that of the control group. The two groups of ammonia (NH4+ ) were mostly maintained at 0 ppm, and nitrous acid (NO2-) reached the highest value of 0.4 ppm in the summer from July to August. After water quality management, the NO2- gradually decreased. The salinity change was followed by rainfall during the summer rainy season, which gradually reduced the salinity from 32 psu to 17 psu. During this period, the salinity of the pool water in the experimental group was higher than that in the control group.
