Journal of Fish Biology, Volume 105, Issue 3, Page 735-751, September 2024.Abstract The ontogenetic development in teleost fish is sensitive to temperature, and the developmental rate has a direct relationship with the environmental temperature within a species' thermal tolerance limit. Temperature determines time to and survival at hatching.
