Circulating hemocyte and microaggregation counts
 Hemocytes were counted and microaggregations were observed at 400x magnification under a phase-contrast microscope in Fast-Read 102® plastic counting chambers to assess their numbers per individual as a proxy for cellular immunity (King and Hillyer, 2013; Stoepler et al., 2013; Duffield et al., 2018). Counting was performed blind to diet and infection cue treatment.
