海水繁養殖研究(2003~2006)-利用ECO-SYSTEM在室內高密度飼育白蝦(Litopenaeus vannamei)之效果
主題: 利用ECO-SYSTEM在室內高密度飼育白蝦(Litopenaeus vannamei)之效果
摘要:
為了解白蝦在室內高密度飼育下之活存與成長而進行此實驗。經中間育成平均體重0.39 g,總重13.85 kg稚蝦,於二個八角型循環水飼育池內飼育,平均放養密度為1,288 ind./m2。飼育至第47天收獲之平均體重為4.81 g,每週成長0.63 g,活存率為47.7 %,平均單位生產量為2.96 kg/m2。飼育期間之水溫、鹽度及溶氧量範圍分別為25.7-29.5°C、23.1-30.5 ppt及6.5-8.9 mg/l。pH、未離子化氨-氮(NH3-N)、亞硝酸-氮(NO2-N)及硝酸-氮(NO3-N) 之範圍分別為6.27-8.29、0.00-0.03 mg/l、0.06-7.24 mg/l及2.02-58.00 mg/l。總生菌數及弧菌數量在水中分別為7.35 ×102-2.13 ×106 CFU/ml及3.00 ×101-7.50 ×102 CFU/ml,在肝胰臟內則為1.13 ×105-1.10 ×106 CFU/g及 1.48 ×103- 3.38 ×105 CFU/g。

標題title(英): Intensive culture of white shrimp Litopenaeus vannamei in the indoor recirculating system
摘要abstract(英): The present study was designed to obtain performance data (growth, survival and yield) for white shrimp (Litopenaeus vannamei) intensively cultured in the indoor recirculating system. Intensive cultivation of white shrimp were conducted into two 20- tons tanks with an average weight of 0.39 g and density of 1,288 ind./m2. The growth rate, mean weight, harvest biomass, and survival rate were 0.63 g/week, 4.81 g, 2.96 kg/m2 and 47.7 %, respectively, as the pond shrimp harvested after 47 days. The water quality parameters, such as water temperature, salinity, pH value, and dissolved oxygen level, were maintained at 25.7 to 29.5°C, 23.1 to 30.5 ppt, 6.27-8.29, and 6.50-8.90 mg/l, respectively, during the experiment. The three kinds of nitrogen wastes, i.e., un-ionized ammonia-nitrogen (NH3-N), nitrite-nitrogen (NO2-N), and nitrate-nitrogen (NO3-N) were determined. Their ranges were from 0.00-0.03 mg/l, 0.06-7.24 mg/l, and 2.02-58.00 mg/l, respectively. The total viable counts and Vibrio viable counts of pound water had a level of 7.35 ×102 to 2.13 ×106 CFU/ml and 3.00 × 101 to 7.50 × 102 CFU/ml, and 1.13 ×105 to 1.10 × 106 CFU/ml and 1.48 × 103 to 3.38 × 105 CFU/g revealed in hepatopancreas, respectively.
