英文摘要	Previous studies have documented female American lobster, Homarus americanus, carrying "abnormal clutches", i.e. with eggs covering less than half of their abdomen. From 2011 to 2014, we worked alongside harvesters to quantify spatio-temporal patterns and reproductive costs of abnormal clutches among 138 738 egg-bearing female lobsters sampled from 193 homeports spread across eastern Canada. Females with abnormal clutches were ubiquitous, being found in 90% of homeports. Their incidence was, however, relatively low, averaging 6% across sampling times and locations. The incidence decreased between spawning and 7-9 months after spawning, potentially due to cases of complete brood failure caused by sperm limitation, and it then increased toward the end of the brooding period, potentially due to repeated catch and release of ovigerous females during the fishery. In most regions, small females were more likely to carry abnormal clutches than larger females. We estimated population-level egg loss between late oogenesis and hatching of embryos at 47-51%, with approximately half being associated with normal clutches and half with abnormal clutches and complete brood failure.
