FIT = n (unknown quantity) for outbreds and FIT = n + 0.25 for inbreds following one generation of full-sibling mating.
✔Replication for each treatment was n = 18 inbred families and n = 20 outbred families. Each family replicate per treatment was represented by n = 4 fish.
✗This “low dose × low temperature” treatment was not included in our analyses because we knew, from our previous work (40, 83), that the low-dose clotrimazole (2 μg/L) alone would not affect population-relevant end points (survival, growth, gonadal development or fecundity), and we sought to maximize replication for the other treatment regimes.
