虚拟种群分析（VPA）是一种广泛使用的鱼类种群分析模型。虽然VPA技术有很多种，但它们使用数据和拟合模型的方式不同，而不是模型本身的形式不同。本手册描述了常见的VPA模型及其所基于的假设，以及相关诊断程序和常见参考点的描述。更重要的是，该手册描述了可用于拟合基于加权最小二乘法的模型的数值技术，这是ADAPT方法的基础。描述的技术，使他们很容易在电子表格中实现。一般方法和具体的例子，使读者能够制定一个适合自己的数据和渔业的方法。
Virtual Population Analysis (VPA) is a widely used model for the analysis of fished populations. While there are very many VPA techniques, they vary in the way they use data and fit the model rather than in the form of the model itself. This manual describes the common VPA model and the assumptions on which it is based, together with descriptions of associated diagnostic procedures and common reference points. More importantly, the manual describes the numerical techniques which can be used to fit the model based on weighted least-squares, which is the basis for the ADAPT approach. The techniques are described so that they are readily implemented in a spreadsheet. General methods and specific examples are given to enable the readers to develop an approach suitable for their own data and fisheries.
