Abstract/ Executive Summary:

Bangladesh is decorated with a lot of rivers and tributaries across her deltaic plains, in which aquaculture is a potential sector to meet dietary needs of protein. The main objective of this study was to assess the knowledge level on aquaculture practices by the fish farmers. The study was conducted in Kahaloo and Sherpur upazilas of Bogra district. Respondent fish farmers were selected using proportionate random sampling technique. Quantitative data was collected using predesigned interview schedule. knowledge on “stocking ratio of fishes of carp poly culture”, “recommended dose of lime”, “application of fertilizers”, “components fish in carp poly culture”, “harmful effect of contaminated water”, “recommended pesticide for removing undesirable fish species” was good enough over other arena of knowledge regarding aquaculture practices. Overwhelming majority of the respondents had low to medium overall mean knowledge on fish culture. Age, education, use of information sources, farm size, fish farming area, annual family income, commercialization, social participation and innovativeness of the respondents had a positive and significant relationship with the knowledge of the respondents. Characteristics of respondent’s viz. use of information sources, education and annual family income were the best predictors and overall contribution variation to the total explained variation in case of knowledge regarding aquaculture practices. The study recommends was that modern technology and its compatibility, viability and application need to telecast frequently in order to generate knowledge on fish farming technology to the relevant farmers.

Commodity: Aquatic animal

Objectives:

1. To determine the extent of knowledge on aquaculture practices

2. To bring out the relationship between selected socio demographic characteristics of respondents and their knowledge on aquaculture practices.

Methodology:

Kahaloo and Sherpur upazilas of Bogra district were the locale of this study. Bogra district consists of 12 upazilas from which Kahaloo and Sherpur were selected using simple random technique. Kahaloo is located at western part of Bogra district whereas Sherpur is located at the southern part. Six unions viz. Kahaloo, Jamgaon, Malancha, Kusumbi, Bishalpur, Khanpur unions were selected by using simple random technique procedure from a total 18 unions of Kahaloo and Sherpur upazilas. Then a list of fish growers of these six unions was prepared with the help of the Upazila Fisheries Officer (UFO). Total numbers of fish farmers of these unions were 366 which constituted the population. Thirty percent of the fish growers were selected from villages of six unions by using proportionate random sampling technique. Resultantly 110 fish farmers constituted the sample of this study. In order to collect valid and reliable information from the farmers an interview schedule containing both open and closed form questions was developed considering the objectives of the study. Ten selected characteristics viz. age, education, family size, information sources use, farm size, fish farming area, annual family income, use of agricultural credit, commercialization, social participation and innovativeness of the respondents were the independent variables were measured and categorized by following standard methodology. Knowledge about aquaculture practices was the dependent variable of this study which consists of thirteen selected questions by covering the following aspects on aquaculture practices viz. (i) recommended dose of lime, (ii) application of fertilizers, (iii) harmful effect of contaminated water (iv) recommended pesticide for removing undesirable fish species, (v) the components fish in carp poly culture, (vi) acquaintance with organic fertilizer, (vii) appropriate dose of organic fertilizers, (viii) stocking density of carp poly culture, (ix) stocking ratio of fishes of carp poly culture, (x) appropriate time of application of urea fertilizer into the pond, (xi) appropriate time of application of TSP fertilizer into the pond, (xii) eradication of undesired fish species and (xiii) appropriate time to release fingerling. Different aspect of knowledge on aquaculture was ranked on the basis of mean. The dependent variable has been categorized on the basis of mean and standard deviation viz. Low (Mean-SD/2), Medium (Mean ± SD/2), High (Mean ± SD/2). A standardized knowledge test was developed to measure the knowledge of fish farmers. However the knowledge index was calculated.

Achievement/Findings:

Fisheries are now one of the most important sectors in the Bangladesh economy. Hence, the demand of fish in Bangladesh is increasing day by day with her ever growing population. Knowledge on scientific fish culture plays a very important role to improve fish production by assisting farmers to make appropriate decision upon adoption of innovations. Among the thirteen aspects of knowledge, respondents had appreciable knowledge on “stocking ratio of fishes of carp poly culture”, “recommended dose of lime”, “application of fertilizers”, “components fish in carp poly culture”, “harmful effect of contaminated water”, “recommended pesticide for removing undesirable fish species”. About half of the respondents had low overall mean knowledge on fish culture and near about similar portion of them had high knowledge category (42.70%). Age, education, use of information sources, farm size, fish farming area, annual family income, commercialization, social participation and innovativeness of the respondents had a positive and significant relationship with the knowledge of the respondent about the aquaculture practices. In case of knowledge on aquaculture practices of the respondents, use of information sources, education and annual family income were the best predictors to the total explained variation of 79.70 percent. Therefore it is recommended that modern technology and its compatibility, viability and application have to telecast frequently in order to generate knowledge
