One way to intensify fish culture without an input of expensive feed is through polyculture. In this way the natural food produced in the culture environment is utilized to a greater extent through compatible or complementary feeding habits of fish which do not compete with each other. In order to utilize natural food to its maximum, and as fish may change their food if their regular food resources become exhausted, it is very important to ascertain the correct ratio between the different species in the polyculture according to the ecological conditions in the pond and to adjust them so that they do not compete with each other.



  1. This resource book consists of a compilation of proven experiences from Asia that are totally field-derived. This book is the result of the participatory workshop process conducted on September 18-28, 2000 at the International Institute of Rural Reconstruction.
  2. The concept of polyculture of fish is based on the concept of total utilization of different trophic and spatial niches of a pond in order to obtain maximum fish production per unit area. Different compatible species of fish of different trophic and spatial niches are raised together in the same...
