Abstract/ Executive Summary:

A comparative carried out was done on the closed water fishery resources between inside and outside the embankment of Meghna Dhonagoda Irrigation Project (MDIP). This research explores that the culture fishery has been developed inside the MDIP project area after the construction of Flood Control, Drainage and Irrigation (FCDI) Project. The average production of fishes in closed water (ponds and borrow pits) was higher inside (2374.39 kg/ha and 2436.37 kg/ha) than outside (1984.32 kg/ha and 2075.01 kg/ha) in 2003-2004 and 2004-2005. The significant difference (p<0.001) was found between the production of two zones. The overall production of closed water increased inside the embankment in all cases except culturable ponds. Production of culturable ponds was higher in outside due to the entrance of natural fish in inundated ponds during monsoon.

Location: Embankment of Meghna Dhonagoda irrigation project

Start Date: 00-00-2003

End Date: 00-00-2005

Program Area: Resource Development and Management

Commodity: Fish

Objectives:

The objective of this study was to conduct a comparative study on the closed water fishery resources between inside and outside the embankment of Meghna Dhonagoda Irrigation Project (MDIP).

Methodology:

Closed water (ponds and borrow pits) survey was carried out in both inside and outside of the embankment. At first 10%, out of 241 villages, was selected randomly from inside the embankment. Then, all the ponds and borrow pits of the selected villages were surveyed. The selected villages covered nine unions inside the project area. Thus, 378 ponds and 22 borrow pits were surveyed by using the pre-tested questionnaires which include questions like fish production, types of fish species, types of culture, ownership, position of pond owners, methods of fish culture, problems of fish culture, etc. Similarly, the same methods were applied in outside the embankment and five villages out of 46 were selected randomly. So, the selected 10% villages include 43 ponds and six borrow pits, which were surveyed, and the data as in inside were collected. The surveys were conducted for the period of two years (2003-2004 and 2004-2005).

Achievement/Findings:

The culture fishery has been developed in the inside of the MDIP project area after the construction of Flood Control, Drainage and Irrigation (FCDI) Project works. The average production of fishes in the closed water (ponds and borrow pits) was higher in the inside than the outside of the regions in both 2003-2004 and 2004-2005. The significant difference (p<0.001) was found between the inside and the outside of the MDIP area. Overall production of the closed water increased in the inside region, however, the production of culturable ponds was higher in the outside region.
