Abstract/ Executive Summary:

An investigation was carried out for a period of one year in Dinajpur district, Bangladesh to know the current aquaculture practices with special emphasis on fish feeds. The study revealed that 89.2% fish farmers were male, 88.3% were Muslims, and 55.8% belong to the age group 41-60 years. In case of education, 45.8% farmers had literacy up to primary level and annual income of 63.3% farmers was below Tk. 50,000. The pond areas of 85.8% farmers were less than 0.50 ha with an average depth of 1.5 m and the water color of most fish ponds (95%) was slightly green and 55% respondents used ground water for polyculture of Indian major carps and exotic carps. In the study areas 30% fish farmers used farm made feeds, 40% used commercial feeds and 30% used both farm made and commercial feeds, and the feed was applied manually twice in a day by most of the farmers (95%). The commonly used feed ingredients were: fishmeal, mustard oil cake, rice bran, maize bran, wheat flour etc. and among the commercial feeds, Mega feed was used by the highest percentage of respondents (35%). The prices of feed ingredients and commercial feeds varied from 22 to 62, and 32 to 110 Tk./kg, respectively. The baseline information on the current aquaculture practices can play vital roles in sustainable aquaculture production.

Keywords: Survey, Aquaculture practices, Fish feeds,

Location: Six upazilas namely Birgonj, Birol, Chirirbandar, Dinajpur sadar, Kaharol, and Khansama under Dinajpur district

Start Date: 00-07-2016

End Date: 00-06-2017

Program Area: Animal Health and Management

Commodity: Aquatic animal

Objectives:

The present aquaculture practices and the different types of feeds being applied for the aquaculture species development, problems and potentialities.

Methodology:

The study was conducted for a period of 12 months commencing from July 2016 to June 2017. Six upazilas namely Birgonj, Birol, Chirirbandar, Dinajpur sadar, Kaharol, and Khansama under Dinajpur district were chosen to conduct the study based on the aquacultural development, problems and potentialities. A questionnaire was prepared with the intention of getting the complete picture of the current aquaculture practices and the fish feeds and feed ingredients used in the selected areas. Data were collected from both primary and secondary sources. Primary data were collected from the respondents by direct interview using the questionnaire, and the secondary data were obtained from different published literatures and statistical data from District and Upazila Fisheries Offices, Non- Government Organization (NGO) officials etc. Focus Group Discussion (FGD) was used to acquire an outline of particular issues such as existing fish composition, pond management practices, feeding methods feed ingredients and feeds, and socio-economic conditions of the fishermen. Three FGD sessions were conducted and each group consisted of 10-15 fish farmers. Cross-check interviews were conducted for the reliability of the collected data with key informants such as District and Upazila Fisheries Officers, school teachers, local leaders, NGO workers etc. First of all, the collected data were coded, summarized and processed for analysis. All possible errors and inconsistencies were eradicated for verification of the data. Then the collected data were analyzed with a computer based software - SPSS (Statistical Package for Social Sciences) version 22, and tables and graphs were prepared with MS Excel (Microsoft Excel 2010).

Achievement/Findings:

It can be concluded that considerable development in aquaculture has been achieved in many regions of Bangladesh, whereas it is still at the preliminary stages in the study areas. On-farm feeds may not contain sufficient amount of nutrients, as the farmers do not have proper knowledge on quality of feed ingredients, formulation, manufacturing process and quality evaluation of the prepared feeds. On the other hand, the nutritive values of commercial feeds are inconsistent, often of low quality. Therefore, further quality assessment of fish feeds is very important. The Government should establish and implement policy on aquafeed for maintaining the required nutritional quality of fish feeds for the sustainable aquaculture production.
