Academic Paper from the year 2021 in the subject Agrarian Studies, grade: 3.84, , language: English, abstract: This paper is a retrospective review of Carp Polyculture in Nepal. Polyculture is an art and science of growing two or more compatible fish species in a pond to maximize production by taking advantage of different spatial distribution and feeding habits. Polyculture concepts rely on the complete utilization of various spatial niches and trophic of a pond to acquire a maximum production per unit area. Carp polyculture is the most common, popular, and successful aquaculture system in Nepal. Carp polyculture is the major aquaculture system contributing to more than 90% of total aquaculture production in Nepal. In 2018/19, total fish production, aquaculture, and productivity were 91,832 t, 70,832 t, and 4.92 t/ha, respectively, which is insufficient to fulfill the growing demand for fish in Nepal. Therefore, it is essential to increase production and productivity.
