— The white perch ( Morone americana ) is an abundant estuarine teleost in eastern North America, with its commercial and trophic importance creating a need for fecundity and recruitment data. In this study, we reevaluated the fecundity of subpopulations of white perch in Chesapeake Bay. Stereological sampling methods were used to determine if environmental changes in the Chesapeake Bay watershed over the last 60 years have altered average fecundity of this species. These methods were compared with automated gravimetric meth-ods to determine the efficacy of using stereological fecundity sampling for white perch. The results of using both methods were statistically the same, as

— The sharpspine skate ( Okamejei acutispina ) is a commercially exploited skate species in the East China Sea, and it is suspected that the population of this species in this region has declined due to fishing pressure and other factors. Nonetheless, information on its life history, which is essential for population assessment and management, is limited. We estimated its age, growth, maturity, and egg-laying season on the basis of data for 331 specimens captured in the East China Sea. Age was determined by counting translucent bands on vertebral centrum sections. Maximum total length (TL) and age were 448 mm and 10 years for females and 444 mm and 9 years for males. Among the 3 growth models applied to length- at-age data, the von Bertalanffy growth function provided the best fit for both sexes (females: theoretical asymptotic length [ L ∞ ]=428 mm, growth coefficient [ k ]=0.30, and theoretical time a zero length [ t 0 ]=−1.04 years; males: L ∞ =422 mm, k =0.31, and t 0 =−1.04 years). Size and age at 50% maturity were 380 mm TL and 4.60 years for females and 357 mm TL and 4.21 years for males. The monthly seasonal reproductive data, including egg case occurrence and oocyte maximum diameter, indicate a prolonged egg-laying season. Our findings indicate that the life history of the sharpspine skate in the East China Sea is characterized by a shorter lifespan, faster growth, and earlier age at maturity than many other skates globally.
- 尖刺鳐（Okamejei acutispina）是中国东海的一种被商业开发的鳐科鱼类，人们怀疑由于捕捞压力和其他因素，该物种在这一地区的种群数量已经下降。然而，对其种群评估和管理至关重要的生活史资料却很有限。我们根据在中国东海捕获的 331 个标本的数据估计了其年龄、生长、成熟和产卵季节。年龄通过计算椎骨中心切片上的半透明带确定。雌性最大总长（TL）和年龄分别为 448 毫米和 10 岁，雄性最大总长（TL）和年龄分别为 444 毫米和 9 岁。在应用于长度-年龄数据的 3 个生长模型中，von Bertalanffy 生长函数对雌雄个体的拟合效果最好（雌性：理论渐近长度 [ L ∞ ]= 428 mm，生长系数 [ k ]= 0.30，理论零长度时间 [ t 0 ]=-1.04 年；雄性：理论渐近长度 [ L ∞ ]= 428 mm，生长系数 [ k ]= 0.30，理论零长度时间 [ t 0 ]=-1.04 年）：L ∞ =422 mm，k =0.31，t 0 =-1.04 年）。雌性的体型和 50%成熟年龄分别为 380 mm TL 和 4.60 年，雄性的体型和 50%成熟年龄分别为 357 mm TL 和 4.21 年。每月的季节性繁殖数据，包括卵箱发生率和卵母细胞最大直径，表明产卵季节延长。我们的研究结果表明，与全球许多其他鳐鱼相比，东海尖吻鳐的生活史具有寿命短、生长快和成熟年龄早的特点。

— The white hake ( Urophy-cis tenuis ) is a groundfish distributed throughout the Gulf of Maine. Catch advice is based on stock assessments done with age-based population dynamics models; however, otolith aging is challenging because of unclear growth increments. To address this concern, we compared the consistency of aging with counts of visual annuli to that of aging with cycles of elemental concentrations measured by using laser ablation inductively coupled plasma mass spectrometry. We tested the hypothesis that oscillations in both environmental conditions and internal physiology through time influence uptake of elements during otolith mineralization. Concentrations of manganese, in comparison with those of the other investigated trace elements (magnesium, strontium, and barium), had the most promising correlation with visual growth increments (~100% age agreement, ±1 year), offering an additional tool to enhance increment identification. In our examination of 550 otoliths collected during 2007–2021, we found that white hake lived a maximum of 10.3 years and exhibited sexual dimorphism in maximum length and age. By using generated von Bertalanffy growth functions, L ( t )=110(1−e −0.113(t+0.45) ) for males and L ( t )=140(1−e −0.113(t−0.30) ) for females (where L ( t ) is length at time t ), size and age at maturity were calculated for males (37.4 cm in total length (TL), 3.3 years) and females (47.4 cm TL, 4.2 years). These results demonstrate that otolith geochemistry can be used to improve the accuracy and precision of the estimation of fish age and maturity, even for challenging species.
- 白无须鳕（Urophy-cis tenuis）是一种分布于缅因湾的底层鱼类。捕捞建议是根据基于年龄的种群动态模型进行的种群评估得出的；然而，由于生长增量不明确，耳石老化具有挑战性。为了解决这个问题，我们比较了用视觉年轮计数进行的老化与用激光烧蚀电感耦合等离子体质谱法测量的元素浓度周期进行的老化的一致性。我们测试了这样一个假设：环境条件和内部生理机能的波动会影响耳石矿化过程中对元素的吸收。与其他研究的微量元素（镁、锶和钡）相比，锰的浓度与目测生长增量的相关性最大（年龄一致性约为 100%，±1 年），为加强生长增量的识别提供了额外的工具。在对 2007-2021 年间收集的 550 块耳石的研究中，我们发现白无须鳕的最长寿命为 10.3 年，并在最长长度和年龄上表现出性双态性。通过使用生成的冯-贝塔朗菲生长函数，雄性为 L ( t )=110(1-e -0.113(t+0.45) ) ，雌性为 L ( t )=140(1-e -0.113(t-0.30) ) （其中 L ( t ) 为 t 时的长度），计算出雄性（总长 37.4 厘米，3.3 年）和雌性（总长 47.4 厘米，4.2 年）的体型和成熟年龄。这些结果表明，耳石地球化学可用于提高鱼类年龄和成熟度估计的准确性和精确度，即使是对具有挑战性的物种也是如此。
