Abstract
Eggs were separated from the setae of berried female rock lobsters (Jasus edwardsii) by soaking in 1 N KOH for 6–12 h. This technique separated almost all of the eggs from the setae and each other with minimal damage. An electronic egg‐counter incorporating a phototransistor was used to count the eggs suspended in water. It had a high degree of accuracy (C.V.= 1.5%) when eggs were counted at a rate of about 200 000 per hour.
