Elevated Plasma Triglycerides and Growth Rate are Early Indicators of Reproductive Status in Post-spawning Female Steelhead Trout (Oncorhynchus mykiss)

Many iteroparous fishes spawn after skipping one or more yearly cycles, which impacts recruitment estimates used for fisheries management and conservation. The physiological mechanisms underlying the development of consecutive and skip spawning life histories in fishes are not well understood. In...

Reproductive Performance and Energy Balance in Consecutive and Skip Repeat Spawning Female Steelhead Reconditioned in Captivity

Steelhead Oncorhynchus mykiss are known for their life history diversity, displaying a range of freshwater residence ages, maturation ages, and spawning intervals. Female maturation is thought to be condition dependent at critical periods, during which individuals falling below energetic...
