Observations on some reproductive traits of Triops granarius (Lucas) (Crustacea: Notostraca)

Reproductive traits of Triops granarius females were examined. Fertilization by males was a prerequisite for oviposition. Clutch size ranged from 1 to 154, and clutch frequency (per 24 hours) from 1 to 9. Clutch size generally increased with increasing body size and increasing age. Total reproductive output was dependent upon life span, and estimated at around 200 eggs for a life span of 25 days. Clutch data indicate that T. granarius may have r-selected traits.
