对来自角鲨的肝脏和白背肌的三种脂质校正模型进行了评估。对于肌肉，根据针对小样本量校正的 Akaike 信息标准值 (AIC(c))，所有三个模型均表现良好，并预测对 δ(13) C 进行类似的脂质校正，比使用先前发布的基于多物种数据的模型进行的预测高出 2.8 ‰。对于与白色肌肉相比具有更高体积 C:N 值的肝脏，所有三种模型均表现不佳，并且通过简单地将 5.74 ‰ 添加到体积 δ(13) C 值来最好地近似脂质校正 δ(13) C 值。
Three lipid correction models were evaluated for liver and white dorsal muscle from Squalus acanthias. For muscle, all three models performed well, based on the Akaike Information Criterion value corrected for small sample sizes (AIC(c) ), and predicted similar lipid corrections to δ(13) C that were up to 2.8 ‰ higher than those predicted using previously published models based on multispecies data. For liver, which possessed higher bulk C:N values compared to that of white muscle, all three models performed poorly and lipid-corrected δ(13) C values were best approximated by simply adding 5.74 ‰ to bulk δ(13) C values.
