Age and size at sexual maturity was determined for 185 male and 96 female smooth skates Malacoraja senta (ranging in size from 370 to 680 mm total length L(T)), collected from the western Gulf of Maine. Maturity ogives for males, based on clasper length, testis mass and the proportion of mature spermatocysts in the testes, suggest that 50% maturity occurs between 9 and 10 years and 560 mm L(T). Maturity ogives for females, based on ovary mass, shell-gland mass and maximum follicle size, suggest that 50% maturity occurs at age 9 years and 540 mm L(T).
对从缅因湾西部采集的 185 只雄性和 96 只雌性光滑狭鳕鱼 Malacoraja senta（体长范围为 370 至 680 毫米）进行了性成熟的年龄和大小的测定。基于腹鳍的长度、睾丸质量和睾丸中成熟精子囊的比例，雄性的性成熟曲线表明，50%的成熟发生在 9 至 10 岁和 560 毫米 L(T)之间。基于卵巢质量、壳腺质量和最大滤泡大小，雌性的性成熟曲线表明，50%的成熟发生在 9 岁和 540 毫米 L(T)时。
