學名: Procambarus Clarkii
英文俗稱: Red Swamp crayfish,Louisiana Red Crayfish
學名中文: 克氏螯蝦
俗稱:小龍蝦, 龍蝦仔(in HongKong)
產地: Louisiana (USA)
Live Span :Around 2-3 years
最佳溫度:15-26C. and growth inhibition occurs at temperatures below 12C (stop eating)
Size: Asults reach 6 cm to 12 cm approx: Many elements will affect the size of this crayfish.(Tank size,food source,Breed line etc)
Color: Wild type Red, Wild type Blue, Dark Blue, White, Pearl Blue, Super Red,Orange,Peach.(Recently have Black )and special type with white antenna
Water condition : Medium - hard water 約6.5-7.5PH (But that is not too critical to this species which is very hardy & adaptable
Tank Setup :Not recommended to be kept with other fish as they are opportunistic feeders & will eat anything they can catch.Also Real Plant is not recommeded too as they will treat it as a food source. And best kept it in separate tanks or in pairs. The number of hiding places eg.Plastic tube. It should always outnumber the crayfish to minimize fighting. Babies require many hiding places or they will cannibalize each other during molts. Also the tank must have a cover on the top.They are good at climbing!!
Sexing: (From the outlook) Adult males of the same age are generally
larger & have
longer slender claws. Females also tend to be
wider across the carapace.
Breeding :It can happen as early as 5-6cm in size. Male will pin female on her back
in
Y shape to transfer sperm which the female can hold onto for long periods of time until she feels its safe to extract her eggs.Weeks to several months. Normally it take approx 30 days to hatch.(Depends on the weather-Winter batch take longer time to hatch) A 10 cm female may produce up to 500 eggs, while smaller females may carry around 100 eggs. Mother Crayfish will take care of the newly hatched crayfish up to 6-8 weeks.But I will recommend to seperate them.Especially for the White or Orange morph baby.
$$$Right!
Food: 雜食.(Normally eat anything!!)
說明:
1. 目前已廣泛分布於世界各地，包括美洲、非洲、歐洲、東亞、夏威夷等地，成為當地嚴重危害的外來入侵物種。美國螯蝦散佈世界各地的途徑主要包括: 農業 (歐美人喜歡食用)、生物防治 (肯亞引入以控制血吸蟲病的中間宿主螺類)、活體生鮮貿易 (由其他國家活體進口歐洲)、誘餌 (引入作為釣鱸魚的誘餌)、寵物水族貿易、自行擴散 (例如由西班牙自然擴散至葡萄牙)、走私 (例如非洲淡水流域出現的族群)。
2.
要注意不要讓他跑!!!

學名: cherax destructor
英文俗稱:yabby
學名中文:破壞者螯蝦
俗稱:台灣稱藍色型的cherax destructor為"天空藍魔蝦"
產地: 澳洲
生存溫度: 1-35(並不代表每隻cherax destructor都可以承受這樣的溫度差,個體會有差異,溫度過度驟升或驟降都可能引起死亡)
最佳溫度:20-25(也有文獻說是22-30)
PH值:約6.5-7.5(可容許鹽度0-12ppt,最高可忍受海水48小時)
含氧量:最低1(mg-1),最佳>5(mg-1)
體重:六個月內可至30g,一年可至50-100g,2-3年可達最大體重320g
最大體長:約30cm
食性:雜食,文獻上說主食為植物
說明:
為澳洲分布最廣泛的螯蝦,1996年澳洲維多利亞共計120個繁殖場供產出25頓,
此蝦可挖掘50cm-200cm,可在挖掘的洞穴中度過整個夏天,也因此會破壞農夫們的水壩
