Kozlowski, J. and Poczyczynski, P. (1999) The effect of light and stocking density on the results of rearing of European catfish (Silurus glanis L.) larvae. Archiwum rybactwa polskiego/Archives of Polish fisheries. Olsztyn [Arch. Ryb. Pol./Arch. Pol. Fish.], pp. 297-306
| Species | Development state | Trait | Primary Data | Secondary Data |
| 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 occurred at fingerling stage in salmonid | Present |
| 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 |
| Silurus glanis | Larvae | Temperature during larval development | 26-28 | 27.0 °C |
| 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 |
