18 June 2022. We are happy to report that our genomic silverside experiment has progressed from "Can we really pull this off?" to "We think we just might" over the past weeks. The silverside larvae of these different crosses show stunning size variability, between populations and temperatures. We already obtained two early life mortality estimates and lots of genetic material, including a full set of crosses reared at 26C and ad libitum food, reaching 20 mm in roughly 4 weeks post hatch. Fingers crossed for the rest of the rearing time.
