    Enzyme treatment for elimination of egg stickiness in tench (Tinca tinca L.) European catfish (Silurus glanis L.) and common carp (Cyprinus carpio L.)

  • Original language description

    Enzyme treatment to eliminate egg stickiness in tench, European catfish and common carp was compared with standard methodology in an attempt to decrease time consuming under hatchery conditions. Eggs of tench and European catfish were exposed to an alcalase enzyme MERCK EC 3.4.21.14 solution 3 minutes after egg activationfor 2 minutes. In tench the highes hatching rate (87.1%) was found with 10,0 ml.l-1 enzyme treatment. The traditional desticking procedure in tench involving milk/clay treatment gave ahatching rate of 74.1% and required 1 hour. The best enzyme concentration in European catfish was 20 ml of enzyme per litre. The traditional desticking procedure in European catfish clay treatment gave a similar hatching rate but procedure required 30 minutes. The eggs of common carp were successfully prevented from stickiness with ALCALASE DX (PLN 04715) using two applications of enzyme from 8 to 20 minutes after fertilization at two level of enzyme concentration (2 ml . l-1 and 20 ml.l
