Effect of Zooplankton Population and Abundance on Fish Production under Two Integrated Fish Livestock Farming Systems in Tropical Climate

摘要

The zooplankton population in the two integrated systems i.e. the duck-fish and chicken-fish integrated farming was analysed in terms of density, species composition, and seasonal abundance. Very high zooplankton density was recorded in both the integrated ponds, almost during the entire study period. A total of22 and 25 species were recorded from duck-fish and chicken-fish integrated ponds, respectively. The total fish production recorded from the ponds was also high. The study suggests that integrated farming systems support large population of natural fish food organisms which results in high growth rate and overall production offish.
