Associated characteristics


Species Development state Trait Primary Data Secondary Data
Silurus glanis Larvae Temperature during larval development 26-28 27.0 °C
Silurus glanis Larvae Reaction to light Light caused aggressive bahavior of fish, they crowded at the bottom, near the walls, and in tank corers. The fish reared in darkness were evenly dispersed in the entire water volume and did not crowd Photopositive
Aristichthys nobilis Larvae Sibling intracohort cannibalism Cannibalism is observed in juveniles Present
Ctenopharyngodon idella Larvae Sibling intracohort cannibalism Cannibalism is observed in juveniles Present
Cyprinus carpio Larvae Sibling intracohort cannibalism Cannibalism is observed in juveniles Present
Coregonus lavaretus Larvae Sibling intracohort cannibalism Never observed Absent
Coregonus albula Larvae Sibling intracohort cannibalism Never observed Absent
Coregonus clupeaformis Larvae Sibling intracohort cannibalism Never observed, no larval cannibalism was ever observed either in fish reared on artificial feed or on natural food Absent
Hucho hucho Larvae Sibling intracohort cannibalism Cannibalism occured at fingerling stage in salmonid Present
Silurus glanis Larvae Sibling intracohort cannibalism Cannibalism was 7% lower in case of fish reared in darkness than in group [The level of cannibalism was directly related to stocking density in that experiment]. Cannibalism may be reduced by fish rearing in darkness, at stocking densities under 25 ind. dm-3 Present
