Abstract

While population foraging behaviour of herbivores has been extensively studied, individual choice is still poorly understood. Because marine ectotherms are strongly influenced by their environment and because a mixed diet is appropriate for herbivores, we hypothesized that Haliotis tuberculata, a large marine gastropod, would not exhibit significant individual consistency in foraging activity and would display generalist food choices. To test these hypotheses, the behaviour of 120 abalone was studied using a choice test of eight macroalgal species (Asparagopsis armata, Palmaria palmata, Enteromorpha intestinalis, Ulva lactuca, Saccharina latissima, Saccorhyza polyschides, Laminaria digitata and stipes of Laminaria hyperborea). Adult Haliotis tuberculata, reared during 4 years in sea-cage structure were transported to a land-based laboratory. Once in the laboratory, eight abalone were randomly assigned to each experimental tank (n= 15 tanks in total). A reflective tag was glued to each individual to allow us to recognize each individual abalone. Foraging activity and food choice was determined for each individual over 3-weeks, with video recording 24 hours a day.
