浮遊珪藻 キートセラス・グラシリス(Chaetoceros gracilis)培養株

— 淡水二枚貝・ウニ・ワムシ・アルテミア用 高栄養生餌 —

淡水二枚貝の飼育では、人工餌や乾燥飼料が主流でした。
しかし、近年では生き餌であるキートセラス・グラシリス(Chaetoceros gracilis)を、安定的に培養できるようになりました。

キートセラスは海産浮遊性珪藻(けいそう)の一種で、微細ながら非常に高い栄養価をもち、
淡水二枚貝(ドブガイ、カラスガイ・イシガイ類など)の主食、ウニやヒトデなど棘皮動物の幼生の餌、淡水ワムシ・アルテミアの栄養補助餌
として幅広く利用され、業務利用のためYAMAHAやヤンマーなどの大手企業が培養されてます。

キートセラスは珪藻特有の高EPA(エイコサペンタエン酸)含量により、人工餌では得られない自然由来のバランス栄養を供給します。

当方では、数年前よりタナゴ繁殖用の二枚貝に使用し、
二枚貝の通年飼育、複数年のタナゴ繁殖利用に成功しています。





商品内容
キートセラス・グラシリス培養液(生体入り)
容量:250mL(貝5個でおよそ50日分)
状態:生きた培養株



細胞密度の目安

良好な培養条件下では、以下のような細胞数が報告されています。
文献値:約 3.1 × 10 の6乗cells/mL(1 mLあたり約310万個)
別報告:培養3日後に 2.2 × 10 の6乗cells/mL 到達
低栄養条件下でも 10 の6乗cells/mL 程度で安定維持が可能

したがって、本培養株もおおよそ 1〜3 × 10の6乗cells/mL(100 mLあたり 1〜3 × 108乗cells)を目安として出荷しています。

※光量・温度・栄養塩濃度により細胞数は変動します。



与え方・飼育・培養のポイント

保存方法

弱めのエアレーションで撹拌(気泡が細かくなる程度)または、毎日数回振る。

1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.
