Gravid females of Caligus rogercresseyi were collected from Atlantic salmon (Salmo salar) from a farm located at Chiloe Island (42 degrees 40'S73 degrees 15'W), Chile, to obtain information about the reproductive output of this parasite in vitro. The egg strings removed from the females were incubated under controlled conditions to obtain virgin adult females. One female which had mated only once produced eleven generations of eggs strings in a period of 74 days. The first egg strings of the females obtained in vitro were produced at 389 degree days ( degrees D) after egg incubation, while the next generations of eggs strings were produced with a periodicity between 4 and 6 days dependent on the water temperature. The average length of the egg string was 3.1mm and the mean number of eggs per string was 31. The values recorded in captivity for the egg string length and the number of eggs per string, were lower than the values recorded in gravid females from the field. One female survived for 79 days and males, maintained separately from the females, survived for 60 days.
从智利奇洛埃岛（42°40'S，73°15'W）的一个养殖场采集到感染桡足类 Caligus rogercresseyi 的怀孕雌性鲑鱼，以获取有关该寄生虫在体外生殖产出的信息。从雌性鲑鱼身上取下的卵串在受控条件下孵育，以获得未交配的成年雌性鲑鱼。一只仅交配过一次的雌性鲑鱼在 74 天内产生了 11 代卵串。在体外获得的雌性鲑鱼的第一批卵串是在卵孵化后 389 度日（°D）时产生的，而接下来的几代卵串则以 4 至 6 天的时间间隔产生，这取决于水温。卵串的平均长度为 3.1mm，每条卵串的平均产卵数为 31 个。在圈养条件下记录到的卵串长度和每条卵串的产卵数低于在野外采集的怀孕雌性鲑鱼记录到的值。一只雌性鲑鱼存活了 79 天，而与雌性鲑鱼分开饲养的雄性鲑鱼存活了 60 天。
