This data set provides feeding rates of juvenile sticklebacks and whitefish of various sizes feeding on seven different zooplankton species in aquaria. The data set has been analysed in Ogorelec et al. (2022) Can young-of-the-year invasive fish keep up with young-of-the-year native fish? A comparison of feeding rates between invasive sticklebacks and whitefish, Ecology & Evolution

The data set consists of 300 feeding observations and 5 columns: 1) fish species, 2) fish size [total size in cm], 3) fish ID, 4) zooplankton species, and 5) feeding rate (number of zooplankton ingested per 3 minutes investigation period]
