We apply a dynamic energy budget (DEB) model to the Icelandic capelin (Mallotus villosus) and introduce a new state variable to capture the roe production of individual fish. Species-specific coefficients are found for the capelin such as the shape coefficient and the Arrhenius temperature. We show how to link the DEB model to measurable quantities such as weight, length, fat, and roe content. We use data on measured 3-year old female capelin from 1999 to 2000 season from the Marine Research Institute of Iceland (MRI) and Matis, an Icelandic Food and Biotech R&D. We then find plausible parameter values for the DEB model by fitting the output of the model to these data. We obtain good fits between theory and observations, and the DEB model successfully reproduces weight, length, fat percentage and roe percentage of capelin. We discuss the effect of maturity on the spawning route of capelin, and describe how we intend to incorporate these results with an interacting particle model for the spawning migration of capelin.
我们将动态能量预算（DEB）模型应用于冰岛毛鳞鱼（Mallotus villosus），并引入一个新的状态变量来捕获个体鱼类的产卵量。为毛鳞鱼找到了特定于物种的系数，如形状系数和阿累尼乌斯温度。我们展示了如何将 DEB 模型与可测量的量（如体重、长度、脂肪和卵黄含量）联系起来。我们使用了冰岛海洋研究所（MRI）和冰岛食品和生物技术研发公司 Matis 提供的 1999 年至 2000 年期间 3 岁雌性毛鳞鱼的测量数据。然后，我们通过将模型的输出拟合到这些数据来找到 DEB 模型的合理参数值。我们在理论和观测之间取得了很好的拟合，DEB 模型成功地再现了毛鳞鱼的体重、长度、脂肪百分比和卵黄百分比。我们讨论了成熟对毛鳞鱼产卵洄游路线的影响，并描述了我们如何打算将这些结果与毛鳞鱼产卵洄游的相互作用粒子模型结合起来。
