Integration of fish culture in hydroponic agriculture in flood-prone areas

Floating bed organic cultivation of different vegetables, flowers, and seedlings have been shown a promising means of agricultural crop production in different wetland areas of Bangladesh. The present study was aimed at finding out the suitability of the integration of fish in this system in water...

The present study was aimed at finding out the suitability of the integration of fish in this system in waterlogged areas.

Over the study period, water quality parameters and fish survival rate did not vary significantly among different treatments. Tilapia showed significantly higher daily and specific growth rates in mono- and polyculture, but silver barb only in polyculture system.
