Abstract/ Executive Summary:

The present study was conducted to determine fish culture techniques practiced by the farmers and cost-benefit analysis in terms of single and multiple ownership of fish farms in Mankun Union of Muktagacha Upazilla of Mymensingh District. For this study 5 fish farms: Ali Mia Fish Farm, Amin Uddin Fish Farm, Shaiful Fish Farm, Tanzil Fish Farm, and Shapon Fish Farm were selected covering the different areas of the study area. Data were collected for a production cycle starting from April, 2014 to November, 2014. The fish farms in the study area were established during 2000 to 2011. Four fish farms were established before 2010 whereas only one fish farm was established in 2011. The maximum area of fish farm was found in Shapon Fish Farm (780 dec.) and minimum area of fish farm was found in Shaiful Fish Farm (123.5 decimal). The minimum size of the pond was 13 decimal and the maximum size of the pond was 84.5 decimal and average pond size was 47.97 decimal. The maximum net income of was observed in Ali Mia Fish Farm (7836 BDT/decimal), whereas the minimum was observed in Shapon Fish Farm (1631 BDT/decimal). The maximum BCR (1.483) and the minimum BCR (1.096) was found in Ali Mia Fish Farm and Shapon Fish Farm respectively. Average BCR was higher in single ownership fish farms (1.30) than multiple ownership fish farms (1.15).The major problem in the study area was high price of feed and low price of fish.

Program Area: Socio-economic and Policy

Commodity: Fish

Objectives:

It has been found that it is the common ego of the farmers to execute their own idea even who received training or collect information from different institutions about modern fish culture technology but they are not interested to practice fish culture on scientific basis rather they are commonly used the technology of their own, learning from their friends or others living in the surrounding areas. Farmers generally conduct fish culture with the moderation of the available technology of fish culture provided by different fisheries research institutes and information about fish culture from another farmer and their friends.

Methodology:

Study area: The study was conducted at Mankun Union of Muktagacha Upazilla situated at 10 miles western side of Mymensingh District headquarters. Many fish farms have been constructed in Mankun Union of Muktagacha Upazilla with in last decade. For this study 5 fish farms- Ali Mia Fish Farm (located in Mankun village), Amin Uddin Fish Farm (located in Nogdharalia village), Shaiful Fish Farm (located in Rudrapur village), Tanzil Fish Farm (located in Adhpakhia village), and Shapon Fish Farm (located in Mujati village) were selected covering the different areas of the study area.

Period of data collection: The present study was undertaken for the period of 8 months. Data were collected for a production cycle starting from April, 2014 to November, 2014. Fish farms were visited at regular time interval, preferably monthly. Collection of data The data were collected directly from farm owners with the direct interview. The essential information’s were noted carefully during interview. Farm record book (daily data record) was consulted and direct monitoring was conducted on the visiting day for the accurate information about the fish culture. Data were collected from each pond of different fish farms. Data on initial size of the fish, stocking density and ratio were collected directly from fish farmer’s record book as well as by oral interviewing.

Calculation of benefit cost ratio (BCR) Cost benefit analysis is an important aspect of any farms. The cost benefit analysis of the studied different fish farms in Muktagacha Upazilla was conducted during the experimental period. Fixed cost, operating cost, total cost, revenue income and net profit were calculated and evaluated. Fixed cost and Operating cost The fixed cost was estimated from the cost involves for land, fry, pond construction etc. The operating cost was calculated from the costs involved to run the farm e.g. Labor salary, feed, fertilizer, lime and medicine, and miscellaneous.

Total cost The total cost was calculated by using the following formula: Total cost = Operating cost + Fixed cost Revenue income The revenue income was calculated by using the following formula: Revenue income (BDT) = Production (kg) × Unit price (BDT) Benefit cost ratio (BCR) The cost benefit ratio was calculated by using the following formula:

Benefit Cost Ratio (BCR) = Total benefits / Total costs

Net profit: The net profit was calculated using the following formula: Net profit = Total revenue – Total cost

Achievement/Findings:

From the above point of view it can be concluded that farm owners practice fish culture in their own way learning from their friends, neighbor or from other farm owners. Farm owners did not follow scientific method of fish culture, but they made reasonable profit by practicing fish culture of their own way. The quality of the farm made feed was satisfactory compare to factory made fish feed. This is because farm owners produced feed for their own farm. That’s why they maintain the quality (protein quality) of farm made feed effectively. Growth performance was also better in case of farm made fish feed than factory made feed. Feed companies should maintain feed quality as they advertise so that farmers wouldn’t be bluffed.
