A feasible path towards year-round production: Effects of temperature and photoperiod on ovarian maturity of subtropical palaemonid, the river shrimp, Cryphiops caementarius

•Gonadal maturation and spawning in winter months finally achieved.•An increase in temperature would be the cue for triggering ovarian development.•Thermic control could be the key to the production of juveniles year-round.•Non-invasive reproduction control methods are promising for native species conservation.•This study contributes to reproduction control on subtropical and temperate palaemonids.
