Název v původním jazyce

Use of three forms of decapsulated Artemia cysts as food for juvenile noble crayfish (Astacus astacus)

Popis výsledku v původním jazyce

Summerling (six-month old) noble crayfish fed two forms of freshly decapsulated (FD) Artemia cysts more than tripled their weight during a 75-day experiment under controlled conditions. Final survival rates were at the level of 90%. Feeding commerciallyavailable industrially decapsulated cysts resulted in both poor growth and reduced survival (22.2%). Therefore FD Artemia cysts may be an effective diet for crayfish culture, but dehydrated industrially decapsulated (DID) cysts should be used with caution to avoid products of low quality. That should be considered especially in slow feeders such as crayfish because of leaching of nutrients from DID cysts. Costs of the processing of freshly decapsulated cysts are discussed.
