Trade-offs Between Growth and Reproduction in Iteroparous Fish
Quick fact
In many iteroparous fish, reproducing can reduce growth by up to 30% in that season, and the energy spent on eggs or sperm is energy not available for the fish's own body growth and maintenance.
Why this is interesting
Imagine a fish that must decide each year whether to grow bigger or to produce eggs. How do these choices shape its entire life?
