“Jurisprudence of Fisheries” is a newly-coined term that represents a course offered by National University of Fisheries. In terms of contents, this course consists of two parts : Part 1 deals with national legislation on fisheries, and Part 2 with international regulations on marine fisheries. However, it is undeniable that the term “Jurisprudence of Fisheries” is somewhat ambiguous in meaning, not to mention that there is no such academic discipline as corresponds to the term. Nevertheless, in view of the fact that this course is actually being lectured and researched at universities. I think it is imperative to define the term as clearly as possible. Therefore, in this paper I will explore the concept of “Jurisprudence of Fisheries”, both as a course and as a research subject. This paper is composed of three main parts: in Part 1, I will consider the definition of the term: in Part 2, I will suggest what should be taught in the course； in Part3, I will discuss the possibility of “Jurisprudence of Fisheries” as a research subject.
