多年来，水产养殖强度一直被用作衡量一个养殖场产量的一种手段，使用三个术语：粗养、半精养和精养水产养殖生产系统。业界对这些术语有相对协调的理解，但似乎不存在明确的通用定义。本文旨在使用三种生产函数群；输入、处理和输出函数明确地描述和定义术语“粗放”、“半强化”和“强化”。这是通过广泛的文献回顾来找到术语的含义来完成的。然后将这些项映射到三个生产函数组。由此产生的框架完成了两件事。首先，从生产功能上对粗养、半精养和精养进行了界定。其次，它创建了八个级别的量表，即水产养殖生产强度量表（APIS），它提供了三个级别的粗放系统、两个级别的半精养系统和三个级别的精养系统。 APIS 允许将当前文献中术语的所有用法映射到 APIS 分数，尽管某些结果可能与当前用法不同。
Aquaculture intensity has been used for years as a means to gauge how much production a site makes using three terms: extensive, semi-intensive and intensive aquaculture production systems. The industry has a relatively coordinated understanding of these terms, but an explicit general definition does not seem to exist. This paper aims to use three kinds of production function groups; the input, treatment and output functions to describe and define the terms extensive, semi-intensive and intensive explicitly. This is done with extensive literature review to find the meaning of the terms. The terms are then mapped onto the three production function groups. The resulting framework accomplishes two things. Firstly, it defines extensive, semi-intensive and intensive aquaculture in terms of production functions. Secondly, it creates an eight level scale, the aquaculture production intensity scale (APIS), that provides three levels of extensive systems, two level of semi-intensive systems and three level of intensive systems. APIS allows mapping of all uses of the terms in current literature to an APIS score, though some results might differ from current usage.
