Effects of Cutting and Cooking Methods on the Shape Forming Properties of Cocktail Shrimp Made of Tiger Prawn

加工條件對草蝦做為雞尾酒蝦成型的影響

摘要


利用溫度刺激來誘發三倍體褐鱒。溫度處理時機定爲授精後5分鐘。以26,27及28℃ 3種溫度,分別處理20,25,30;15,20,25及10,15,20分鐘。測定受精卵,魚苗之活存率及其染色體倍性,以評估誘發效果。結果各試驗組均能成功的誘發產生三倍體,且誘發率高達70~94%。如果同時考量三倍體誘發率及魚苗活存率,則以授精後5分鐘,在28℃下處理10分鐘或15分鐘這二組結果最好,其三倍體誘發率及魚苗活存率分別爲94.2與93.8%及82.6與70.6%。

The optimation of heat shock was studied to induce triploidy in brown trout,Salmo trutta.The heat shocks were administrated 5 minutes after fertilizationat temperatures ranging from 26 to 28℃ with the duration time ranging from10 to 30 minutes.The karyological examination and survival rate of embryoshad been done to evaluate the efficiency of triploid induction.Moderate tohigh triploidy rates(70% to 94%)were observed in all tests.If the triploidinduction rate and survival rate were concerned together,temperature at 28℃and a duration of 10 or 15 minutes,applied 5 minutes after fertilization gavethe best performances.
