龍蝦生長周期多長時間

　　天然環(huán)境中龍蝦生長周期為6至12個月，人工飼養(yǎng)龍蝦生長周期一般6個月。小龍蝦生長適宜水溫是18~31℃，最適水溫22~31℃。人工飼養(yǎng)龍蝦所吃食物中含有激素，比天然環(huán)境中的龍蝦成長快、性成熟早，且雄性個體比雌性個體長得快、性早熟。

龍蝦生長周期多長時間

　　人工飼養(yǎng)的龍龍蝦，特別是喂養(yǎng)膨化顆粒飼料的龍蝦和沒喂膨化顆粒的龍蝦，兩者的在經(jīng)過一般時間對比后，體重完全不同，前者體重可達50g,而后者只有30g左右。另外雄性蝦的長勢要快過雌性蝦。

　　人工飼養(yǎng)的龍蝦一般要11次脫殼才能達到性成熟，也就是說小龍蝦每一次脫殼，都是一次階段性的成長。

　　小龍蝦在6厘米以前，生長很緩慢，不過從幼苗期到性成熟，人工飼養(yǎng)6個月就可以了，小龍蝦每成長一次，都會退去外殼，每退殼一次，龍蝦的體重較前增長95%。龍蝦要歷經(jīng)11次退殼，就可以達到性成熟了，也就是成熟蝦了。清水養(yǎng)龍蝦的產(chǎn)質(zhì)會更高，龍蝦生長得快慢取決于它對蛋白質(zhì)的吸收。

　　雌性小龍蝦的性成熟期比雄性的性成熟期要晚一個月左右，一般雌性小龍蝦性成熟年齡在7至8個月，而雄性的性成熟則在6至7個月，雌性小龍蝦的生態(tài)壽命比雄性小龍蝦的生態(tài)壽命要長1年左右，雌性小龍蝦的生態(tài)壽命是5.3年，而雄性小龍蝦的生態(tài)壽命則為4.3年。

　　結(jié)語：關(guān)于龍蝦生長周期多長時間大家都清楚了，人工飼養(yǎng)的龍蝦能攝入更為豐富的養(yǎng)分，也能令龍蝦更快的增長，養(yǎng)殖過程中雄性龍蝦后期明顯比雌性龍蝦生長要快。在自然的水域里，每難找到3年以上的小龍蝦，人們大量的捕撈，使它們的很難達到生態(tài)年齡。
