Stable isotopes are used to study trophic and movement ecology in aquatic systems, as they provide spatially distinct, time-integrated signatures of diet. Stable isotope ecology has been used to quantify species-habitat relationships in many important fisheries species (e.g., penaeid prawns), with approaches that typically assume constant values for diet-tissue discrimination and diet-tissue steady state, but these can be highly variable. Here we provide the first report of these processes in Metapenaeus macleayi (eastern school prawn).

对虾肌肉组织中 δ13C 和 δ15N 的饮食组织区分和周转

稳定同位素用于研究水生系统中的营养和运动生态学，因为它们提供了空间不同、时间整合的饮食特征。稳定同位素生态学已被用于量化许多重要渔业物种（例如对虾）的物种-栖息地关系，其方法通常假设饮食组织区分和饮食组织稳态的恒定值，但这些可能变化很大。在这里，我们提供了Metapenaeus macleayi（东部对虾）中这些过程的第一份报告。
