曬池試驗結果顯示只要池水完全抽乾下,遮蔽池與無遮蔽池所需的曬池時間沒有差 別,池底曝露在空氣中至少需要10天,才能保證改善池塘底土的效果。添加基肥試 驗由池水溶氧變化發現無遮蔽池發酵完成時間比遮蔽池快3天。為了瞭解太陽能發電 板設置後可能對文蛤池水質的影響,進行0、40%、70%不同遮蔽率下的養殖試驗。經 過6個月的實驗期間發現溫度、照度及基礎生產力隨遮蔽率率增加而降低,綜合水質 分析結果顯示,文蛤養殖池的遮避率超過40%後,養殖水質環境即開始出現明顯的變 化。底棲動物部分,遮蔽率0%與40%的群聚分布則在統計上有較高的相似度。藉由底 質及底棲動物結果說明出遮蔽率40%養殖池為相對優良的底棲環境。土壤及水體海洋 弧菌數的部分下隨遮蔽上升有增加的情況,但是文蛤體內的海洋弧菌數確有隨著遮 蔽度增加而有減少的情形。11/5採樣文蛤測量各試驗池文蛤的平均體重分別為:S0組9.47 ± 2.79g、S-40組9.04 ±1.85g及S-70組7.24 ± 1.63g。1各試驗組的平均活 存率:S-0組77.5±4.24%、S-40組76.15±1.48%及S-70組64.6±1.41%。另在文蛤投餵 藻類的試驗中投餵小環藻有最佳的活存率、增重及SGR,是值得提供文蛤現場養殖之 餌藻藻株。

研究報告摘要(英)


 The results of the Drying pond test show that as long as the pond water is completely drained, there is no difference in the drying time required for the shaded pond and the unshielded pond. It takes at least 10 days for the bottom of the pond to be exposed to the air to ensure the effect of improving the pond subsoil. In the experiment of adding basal fertilizer, the change of dissolved oxygen in the pond water found that the fermentation completion time of the uncovered pond was 3 days faster than that of the covered pond. In order to understand the possible impact on the water quality of the clam pond after the installation of solar power panels, a breeding experiment with different shade rates of 0, 40%, and 70% was carried out. After 6 months of experimentation, it was found that the temperature, illuminance and basic productivity decreased with the increase of the sheltering rate. The comprehensive water quality analysis showed that after the sheltering rate of the clam farming pond exceeded 40%, the aquaculture water environment began to change significantly. For the benthic fauna, the cluster distributions with a coverage rate of 0% and 40% are statistically similar. The results of benthic and benthic animals show that the breeding pond with a shelter rate of 40% is a relatively good benthic environment. The number of marine vibrio in the soil and water body increased with the increase of the shade rate, but the number of marine vibrio in the clams did decrease with the increase of the shade rate. The average body weight of the clams in the test pools measured by the 11/5 sampling of clams were: 9.47 ± 2.79 g in the S-0 group, 9.04 ± 1.85 g in the S-40 group, and 7.24 ± 1.63 g in the S-70 group. The average survival rate of each experimental group: 77.5±4.24% in S-0 group, 76.15±1.48% in S-40 group and 64.6±1.41% in S-70 group. In addition, in the experiment of feeding Clam clams to algae, feeding Cyclotella sp. has the best survival rate, weight gain and SGR, which is worthy of providing algae strains for cultivation of clams.
