Abstract/ Executive Summary:

The study was aimed to determine the extent of utilization of aqua drugs for fish health management by the fish farmers. The sample of the study consisted of 92 fish farmers from four villages of Muktagachha Upazila under Mymensingh district of Bangladesh. Data for the study were collected from 10 January to 13 May, 2017 using an interview schedule by personal interviewing of the fish farmers. The findings revealed that 62.0percent of the fish farmers were accustomed to utilizing the medium level of aqua drugs, 29.3 percent utilize a low level and only 8.7 percent of them utilize a high level of aqua drugs. Among six types of aqua drugs: disinfectants were used by 100 percent of the fish farmers, gas reducers were used by 93.47 percent, growth promoters were used by 72.83 percent, oxygen suppliers were used by 85.87 percent, probiotics were used by 65.22 percent and antibiotics were used by 53.26 percent of the fish farmers. Correlation analysis showed that farm size, the area under fish farming, annual income, extension media contact and training on aquaculture of the fish farmers had a positive and significant relationship with the extent of utilization of aqua drugs by the fish farmers. The study revealed that effective training and motivational programs should be organized by both government and non-government organizations for the fish farmers to enable them taking timely decisions and utilize the appropriate dosage of aqua drugs for fish health management which will help the fish farmers to increase their income and also improve their livelihood status.

Objectives:

(i) to determine the extent of utilization of aqua drugs for fish health management by the fish farmers; (ii) to describe the selected characteristics of the fish farmers; and (iii) to assess the relationships between the selected characteristics of the fish farmers and their extent of utilization of aqua drugs.

Methodology:

Muktagachha Upazila under Mymensingh districts well communicated and acquainted to the researcher. Four villages of Muktagachha Upazila were purposively selected as the locations of the study namely Khilgati, Baniakaji, Etigachi and Kheruajani for obtaining a representative sample of the study. The selection was based on an important consideration also i.e. availability of a large number of fish farms in those areas suitable for fish culture where many farmers adopted fish farming through the utilization of aqua drugs. As a result, it was assumed that conducting empirical research in those four villages of Muktagachha Upazila would best reflect the reality of the situation. Data were collected from 10 January to 13 May, 2017 using a structured interview schedule by personal interviewing from 92 randomly selected (31 percent of the total population) fish farmers from a population of 300. The extent of utilization of aqua drugs for fish health management was the focus variable and eleven selected characteristics of the fish farmers were selected as explanatory variables namely age, level of education, household size, farm size, the area under fish culture, annual income, extension media contact, training on aquaculture, duration of using aqua drugs, knowledge on fish farming and training need for aquaculture. For clarity of the research, six major categories of aqua drugs were identified such as disinfectants, gas reducer, oxygen supplier, probiotic, growth promoter and antibiotic. Each respondent was asked to indicate the extent of utilization of aqua drugs for fish health management by using a 4-point rating scale such as frequently, occasionally, rarely and not at all weights were assigned to these responses as 3, 2, 1 and 0, respectively. Thus, the aqua drug utilization score for a respondent could range from 0-18, where 0 indicated no utilization of aqua drugs at all, while 18 indicated the highest level of utilization of the drugs for fish health management by fish farmers. The mean value of the extent of utilization of aqua drugs was computed and on the basis of individual mean value, a rank order of the extent of utilization of aqua rugs was prepared. For making rank order UtilizationScore(US) was also computed. The US was computed by using the following formula: US = (Nf×3) + (No×2) + (Nr×1) + (Naa×0). Where, US = UtilizationScoreNf= Number of fish farmers utilized aqua drugsfrequentlyNo= Number of fish farmers utilized aqua drugs occasionally Nr= Number of fish farmers utilized aqua drugs rarely Nnaa= Number of fish farmers utilized aqua drugs, not at all this, the Utilization Score (US) of individual aqua drugs could range from 0 to 276, where ‘0’indicating ‘no utilization of aqua drugs and ‘276’ indicating frequently utilization of aqua drugs for fish health management by the fish farmers.

Achievement/Findings:

The aqua drugs are very important for fish culture in Bangladesh. The findings showed that the majority of the fish farmers (91.3 percent) utilized low to medium amounts of aqua drugs for fish health management. There were six types of aqua drugs that have been used by the fish farmers at different stages of fish health management in the study area namely disinfectants, gas reducers, oxygen suppliers, growth promoters, probiotics and antibiotics. The study leads to conclude that effective training and motivational programs should be organized by both government and non-government organizations for the fish farmers to enable them taking timely decisions and utilize the appropriate dosages of aqua drugs for fish health management.
