Abstract
Research has shown that the stress response in adult fish can lower sex hormone levels, disrupt mating behavior, and reduce overall reproductive success (1). While stress is known to impact an individual's ability to reproduce, its effects on offspring after birth remain unclear. Specifically, the influence of maternal stress during gestation on offspring growth and maturation is still unknown.
To better understand how maternal stress affects offspring development, we will study the live-bearing fish Alfaro cultratus from birth to reproductive maturity. We will observe the timeline of developmental milestones in offspring whose mothers experience stress during gestation to assess potential long-term effects on growth and future reproduction. This study will provide insights into how maternal stress impacts fish offspring and may have broader implications for other live-bearing species.
