The food of the pollan, Coregonus autumnalis pollan Thompson, in Lough Neagh, Northern Ireland
Stomach contents of pollan caught monthly throughout the year were examined. Stomach fullness was significantly correlated with water temperature. Adult pollan fed on bottom fauna, mainly chironomid larvae, in October‐March, chironomid pupae in April and on Daphnia spp. in May‐September. Immature (0...

Summary: | Stomach contents of pollan caught monthly throughout the year were examined. Stomach fullness was significantly correlated with water temperature. Adult pollan fed on bottom fauna, mainly chironomid larvae, in October‐March, chironomid pupae in April and on Daphnia spp. in May‐September. Immature (0+ and 1 +) fish also ate other cladocerans and copepods. While there is no evidence for selection of any benthic prey species, adult pollan appear to be highly selective feeders on Daphnia spp. in summer. |
