- •
Three Diaphus species spawned during summer with interspawn periods of 3–9 days.
- •
Females with hydrated ovaries occurred during the daytime in the mesopelagic layer.
- •
Egg size at hydration and batch fecundity was largest and highest in D. watasei.
- •
D. garmani was characterized by maturation at a smaller body size.
- •
D. watasei used greater energy for reproduction as larger-sized mature adults.
