To examine the effects of food limitation on naupliar production, experiments were carried out on groups of 25 individually-isolated oviger females. Four replicates were used, each fed one of three different levels (dry weight; DW) of shrimp meat, prepared as described in Norsker and Stottrup (1994). The cultures were harvested at three-day intervals and the number of females registered at each harvest. Average female productivity was estimated from: P = (N/F)/T where N is the number of nauplii harvested over a three-day period, F the average number of female copepods (F, - F,)/2, where F, and F, are the final and initial number for each 3 day-period and T is the number of days.
