What is the typical reproductive maturity age for Orange Roughy?
Answer
27 to 40 years old
Orange Roughy exhibits extreme longevity but suffers from exceptionally late reproductive maturation. Scientific data indicates that individuals often do not begin breeding until they reach an age range between 27 to 40 years old. This late spawning age, combined with their potential lifespan extending beyond 140 years, means that the species has extremely low resilience to population decline. If fishing pressure significantly reduces the adult population before they can reproduce multiple times, recovery spans many human generations.
