Summary

Hatching of eggs of Anguillicola crassus was studied at temperatures between 5 and 30°C. Hatching occurred between 10 and 30°C and the incubation time was inversely related to temperature. Survival, spontaneous and excitatory rate of activity of 2nd-stage larvae of A. crassus were also affected by temperature. The percentage of larvae eaten by Paracyclops fimbriatus was not always influenced by the activity of the larvae. Penetration efficiency into the haemocoel of the intermediate host was highest for freshly hatched larvae and declined gradually with age. Completely non-active larvae were still able to penetrate, although penetration efficiency was lower.
