攝食含不同胡蘿蔔素的食物可增進蝦的蝦紅素,光照及背景也可能影響色澤。除了增進色澤,蝦紅素也扮演了生物功能,如增進成長及存活。本研究之目的在於探討光照狀態、藻水及飼糧蝦紅素對草蝦後期幼蟲的呈色及後續成長與存活的影響。一以複因子2×2×2的處理安排,包括添加80 mg/kg蝦紅素或不添加的兩種飼糧餵予草蝦後期幼蟲,在添加綠光等鞭定鞭藻3.63-8.70 μ/L或不添加的水中且在全光照或全黑暗狀態下養殖四星期。隨著蝦體的成長,蝦紅素顯著地下降。光照僅在第四星期顯著的減少蝦色素的下降率,而藻水及飼糧蝦紅素自第一星期即顯著地減少蝦色素的下降率。光照、藻水及飼糧蝦紅素對蝦的成長無影響。整個試驗期間,光照環境下蝦的存活高於在黑暗環境下。除了第三星期,在有藻水環境下蝦的存活也高於無藻水的環境。飼糧蝦紅素僅在第一星期增進蝦的存活。到第四星期,蝦的存活與蝦體之蝦紅素含量有顯著的正相關。此結果可建議當蝦後期幼蟲成長其蝦紅素降低時,要獲得較佳的存活,維持蝦紅素含量有其必要性。
The astaxanthin content of penaeids can be increased through ingestion of food containing different carotenoids. Illumination and background probably affect pigmentation as well. There are some indications that astaxanthin also plays biological roles other than in pigmentation, such as improvement of growth and survival. The aim of this study was to find out the effects of light regime, algal in the water, and dietary astaxanthin on body astaxanthin, and subsequent growth and survival of tiger prawn Penaeus monodon post-larvae. An experiment with 2 × 2 × 2 factorial arrangement of treatments was conducted, which included 2 diets without or with astaxanthin supplementation (80 mg astaxanthin/kg) fed on tiger prawn post-larvae in water without or with the addition of microalgae (Isochrysis galbana, 3.63-8.70 μg/L) under a 24-h dark or light environment for 4 wk. Body astaxanthin concentrations decreased significantly as prawns grew. Light had significant effects in preventing body astaxanthin reduction only during the 4th wk, but both algae in the water and dietary astaxanthin had significant effects in preventing body astaxanthin reduction from the 1st wk. There were no significant effects of light regime, algae in the water, or dietary astaxanthin on prawn growth. Throughout the experiment, the survival of prawn reared in the light was significantly higher than that for prawn reared in the dark. The survival of prawn reared in algae-containing water was significantly higher than that of prawn reared in clear water except in the 3rd wk. Dietary astaxanthin improved prawn survival only in the 1st wk. Only in the 4th wk did survival have a positive correlation with prawn body astaxanthin concentration. The results suggest that it is essential to maintain a certain level of astaxanthin in tiger prawn post-larvae for better survival while the prawn are growing and their astaxanthin is decreasing.
