我们目前正在实验室培养第4代乌贼乌贼。第一代(F1)是在夏季从野生(里亚福尔摩沙-葡萄牙南部)采集的卵培育出来的，平均温度为27°C±3°。本研究从初秋至春末，在15°C±4°C的温度下，对第二代(F2)乌贼进行了饲养，比较了F2与F1的生活史。在每个实验中都使用了30种乌贼。墨鱼从一天大开始生长，直到周期结束(每个种群中的最后一只雌性乌贼死亡)。在更低的温度下养殖的F2乌贼的生命周期更长，几乎为9个月(260天)，而F1乌贼的生命周期不到6个月(165天)。F2代乌贼生长显著(U=0.00；p<0.01)，雄性和雌性的平均体重分别为343.3±80.5g和248±33.1g，而F1的平均体重分别为199.6±40g和143.3±30.9g。F2代雌虫的繁殖力(225枚卵)高于F1代(144枚卵−1)，产卵量较大(t=45.60752；p<；0.0001)，重0.74±0.18g，高于F1代的0.46±0.11g；较大(t=7,144783；p<；0.0001)，重0.10±0.02g，与夏季种群的0.09±0.02g相比。
We are presently culturing the 4th generation of thecuttlefish, Sepia officinalis in our laboratory. A firstgeneration (F1) was grown from eggs collected from the wild (Ria Formosa–South Portugal) during the summer, at mean temperatures of 27°C ± 3°. In the present study, a second generation(F2), originated from eggs laid in the laboratory by females from F1 wascultured between the start of autumn and the end of spring, at meantemperaturesof 15 °C ± 4 °C. The life cycle ofcuttlefish from F2 was compared to F1. Populations of 30 cuttlefish were usedineach experiment. Cuttlefish were grown from one day old until the cycle wascompleted (when the last female in each population had died). Cuttlefish fromF2cultured at much lower temperatures had a longer life cycle, of almost 9 months(260 days) compared to cuttlefish from F1, which completed their cycle in lessthan 6 months (165 days). Cuttlefish from F2 grew significantly larger (U =0.00; p < 0.01) with mean weights of 343.3 ± 80.5 g and248 ± 33.1 g for males and females, respectively, comparedtoF1 (199.6 ± 40 g and 143.3 ± 30.9 g formales and females, respectively). Females from F2 had higher fecundity (225eggsfemale−1) compared to females from F1 (144 eggs perfemale−1), produced bigger eggs (t = 45.60752; p < 0.0001),weighing 0.74 ± 0.18 g, compared to 0.46 ± 0.11 fromF1,and bigger hatchlings (t = 7,144783; p < 0.0001), weighing 0.10 ±0.02g, compared to 0.09 ± 0.02 g for the summerpopulation.
