海水繁養殖研究(2003~2006)-飼料中龍鬚菜添加量對草蝦成長及脂肪酸組成之影響
主題: 飼料中龍鬚菜添加量對草蝦成長及脂肪酸組成之影響
摘要:
本研究探討飼料中添加龍鬚菜(Gracilaria sp.)粉末,對於草蝦成長及體脂肪酸組成之影響。基礎飼料中添加0、1、3、5及10%龍鬚菜粉末,飼育120天,平均活存率為57.5-67.5%,各組間並無顯著性之差異。但在平均體重以添加3%者最高,1%次之,而與其他各組間有顯著差異,在餌料係數,也以3%者最好,1%者次之,優於其他各組。飼育後草蝦蝦體脂肪中之高度不飽和脂肪酸如花生四烯酸(arachidonic acid) 、二十碳五烯酸EPA(eicosapentaenoic acid)及二十二碳六烯酸DHA (docosahexaenoic acid)等,含量增加。因此飼料中龍鬚菜添加1-3%,可使草蝦成長正常,並使體內高度不飽和脂肪酸增加。

標題title(英): Influence on Penaeus monodon growth and fatty acid composition with different Gracilaria sp. supplementation in feeds
摘要abstract(英): The power of dried seaweed Gracilaria sp. was supplemented to experimental feeds at different levels from 0% to 10% for rearing of grass shrimp, Penaeus monodon. After 120 days, the survival rates were between 57.5% and 67.5%, not significantly different among groups. The weight gain and feed coefficient were higher in the 3% group than those of other groups. Supplementation of appropriate amount of Gracilaria sp. in feed will increase the concentration of highly unsaturated fatty acids in shrimp body and enhanced the growth and survival rate of grass shrimp.
