Abstract/ Executive Summary:

The study was conducted to evaluate the comparison of production performance and economics of different carp polyculture systems in Gangni Upazila under Meherpur district from July to November 2015. PRA tools such as questionnaire based interview, cross check interview etc. were used for primary data collection and secondary information were used to assess the performances in aquaculture activities. Forty pond fish farmers were randomly selected,among them7 (18.0%), 17 (42.0%), 3 (8.0%), 7 (18.0%) and 6 (15.0%) farmers were engaged with carp-mola, carp-tilapia, carp-koi, carp-shing polyculture and carp fattening, respectively. Only 23% farmers had small ponds (5dec -15 dec), 35% medium (16 dec-25 dec) and 40% had large ponds (above 25 dec). The minimum water depths of 23% ponds were within 0.5m-1.0 m, 53% were 1.00m-1.5 m, 17% were 1.6m -2.0 mand 7% were up to 2.0 m. From the survey, it was found that 14 (35.0%) of the farmers applied supplementary/homemade feed prepared with rice bran and mustard oil cake, 17 (43.0%) farmers used commercial feed and 9 (22.0%) farmers were depended on natural feed. Average fish production of the farmers was 6274 kg ha^-1yr^-1. The calculated highest fish production 7,904 kg ha^-1yr^-1and net income was BDT 2,42,060 ha^-1yr^-1, respectively in carp-tilapia polyculture system. The lowest fish production was 5,187 kg ha^-1yr^-1and net income was BDT 1,66,478 came in carp-koi polyculture system. From the result of present study, it is clear that fish production and financial benefit in carp-tilapia polyculture were higher than others. The present findings reveal that carp-tilapia polyculture system is more suitable and profitable culture system than other polyculture systems existing in Gangni upazila of Meherpur district.

Program Area: Socio-economic and Policy

Commodity: Carp fish

Objectives:

The present study was planned to know the present status of aquaculture practices in the Gangni Upazila and to compare production performance and economics among different carp polyculture systems.

Methodology:

The study was carried out for 5 months from July to November 2015. It was conducted in selected nine villages named Baneapukur, Jugirgofa, Sholotaka, Bathanpara, Sharbati, Hariadha, Bhobanipur, Harabhanga and Gangni under Gangni Upazila of Meherpur district. Pond fish culture was heavily concentrated in the area because PKSF (Pally Karma Sohaok Foundation), PSKS (Palashipara Samaj Kallyan Samity), DBS (Daridra Bimochan Sangtha) and government have been working for many years with fish farmers to increase fish production and their economic development. Forty fishermen each with at least one fishpond were randomly selected from the study area. Participatory Rural Appraisal (PRA) is a group of methods to collect information from pond fish farmers in participatory fashion (Chambers, 1992). PRA tools such as focus group discussion (FGD), questionnaire based interview, cross check interview etc. were used for primary data collection and secondary information were also used. In order to collect relevant information, a questionnaire was carefully designed keeping the objectives of the study in view. Before preparing the final questionnaire, it was pretested in the study area. Thus, some parts of the questionnaire were improved, rearranged, modified and added in the actual and practical experiences. Finally, a set of items were listed and grouped in the logical sequence, so that, the target group could answer easily.The questionnaire interviews were conducted at the pond sites and home in the selected area. Before going to make an actual interview, a brief introduction about the objective of the study was informed to each of the farmers and assured them that all information would be used for their welfare. At the time of interview, the physical conditions of fish farmers’ ponds and the fish cultivation methods like pond preparation, application of food and fertilizers, harvesting etc. were closely observed because there was a scope to well understanding the fish production technology in the study area. After collecting data, it was verified by cross-checking to eliminate errors and inconsistencies. Collected data from various sources were coded and entered into a data base system using “Microsoft Excel Software” and “SPSS” (Statistical package for social science) computer package.

Achievement/Findings:

It is noted that proper management and stocking density can improve the production performance of carp polyculture system and also contribute to overall economic improvement of fishermen. Among five culture systems, average production and net profit from carp-tilapia polyculture were found higher during present survey. For this reason, this culture technique was widely accepted by the local fish farmers (17 out of 40). From the present findings, it reveals that carp-tilapia polyculture system is possibly more suitable and profitable culture system than other polyculture systems existing in Gangni upazila of Meherpur district.
