Although the round goby Neogobius melanostomus has become established throughout the Laurentian Great Lakes, a multi-model inference (MMI) approach toward characterizing round goby growth in the Laurentian Great Lakes has yet to applied using otolith-derived data. Further, spatial variation in round goby growth among lakes has yet to be investigated. For each sex, growth of round gobies at three locations of Lake Michigan and four locations of Lake Huron was investigated using MMI, based on information theory, with three candidate growth models. These three growth models included the von Bertalanffy model, the Gompertz model, and the logistic model. The von Bertalanffy model was most often selected (13 out of 14 cases) as the ‘best’ model among all candidate models, followed by the logistic model. None of the best models were strongly supported as a ‘clear winner’. At least one additional model was supported by the data in each of the 14 cases, indicating that there is a substantial degree of uncertainty in model selection. When model selection uncertainty was ignored, standard errors of growth parameters were underestimated in 8 of the 14 cases. Overall, round gobies in Lake Michigan attained larger sizes at age and grew faster than in Lake Huron. Based on multi-model inference, our study provided a robust assessment of round goby growth, which will be essential in better managing sport fisheries in both lakes.

使用多模型推理对密歇根湖和休伦湖的虾虎鱼生长进行建模

虽然轮虾虎鱼Neagobius黑色劳伦大湖地区已经建立了一个多模型推理(MMI)方法来表征劳伦大湖中虾虎鱼的生长,但尚未使用耳石来源的数据进行应用。此外,湖泊之间的虾虎鱼生长的空间变化尚待研究。对于每种性别,基于信息论,使用MMI和三个候选生长模型,研究了密歇根湖三个地点和休伦湖四个地点的轮状growth虾的生长。这三个增长模型包括von Bertalanffy模型,Gompertz模型和logistic模型。在所有候选模型中,最常选择von Bertalanffy模型(14个案例中的13个)为“最佳”模型,其次是逻辑模型。没有一个最好的模型得到“明确的赢家”的大力支持。在这14种情况下,数据至少支持一个附加模型,这表明模型选择存在很大程度的不确定性。当忽略模型选择的不确定性时,在14个案例中的8个案例中低估了生长参数的标准误差。总体而言,密歇根湖的圆形虾虎鱼年龄较大,生长速度比休伦湖大。基于多模型推论,我们的研究提供了对虾虎鱼生长的可靠评估,这对于更好地管理两个湖泊的体育渔业至关重要。密歇根湖的圆形虾虎鱼年龄较大,生长速度比休伦湖大。基于多模型推论,我们的研究提供了对虾虎鱼生长的可靠评估,这对于更好地管理两个湖泊的体育渔业至关重要。密歇根湖的圆形虾虎鱼年龄较大,生长速度比休伦湖大。基于多模型推论,我们的研究提供了对虾虎鱼生长的可靠评估,这对于更好地管理两个湖泊的体育渔业至关重要。
