Abstract/ Executive Summary:

A study was conducted to determine the present biosecurity status in some commercial aquafarms of selected Upazila under Kishoreganj and Mymensingh districts of Bangladesh. A total of 30 fish farms from Kishoreganj and Mymensingh district were surveyed. Data were collected through questionnaire interview and participatory rural appraisal tools like focus group discussion. The results showed that majority of the farmers did not have good understanding of biosecurity procedure. Biosecurity measures such as sprays and footbath facility, sanitary latrine, showers, disinfection of transport equipment, providing protective clothing for visitors and quarantine facilities were totally absent in both districts. However, 80% of the farms did not have scope for pollutant entrance and most of the farmers used ground water sources. Additionally, they took protection against fish stealing (80%), stocked disease free fry (100%), removed bottom waste and dried culture ponds after two or three production cycle (66.67%) and measured water quality parameters (53.33%) on monthly basis. Other biosecurity measures such as restriction of visitor's movement, control rodents and insects in feed storage, keeping domestic animals confined to the farm, water exchange in the pond, controlling predator in farm and disinfection of equipment used for culture operation. The collected data would be used as the preliminary study record and for further improvement of the overall biosecurity status.

Location: 15 aquafarms located in 3 Upazila under Kishoregonj district (viz., Kishoregonj sadar, Kotiadi and Pakundia) and another 15 aquafarms located in 3 Upazilas under Mymensingh district (viz., Isharganj, Nandail and Gouripur), Bangladesh

Program Area: Animal Health and Management

Commodity: Fish

Objectives:

To determine and compare the status of biosecurity management in the aquafarms of some selected areas of Kishoregonj and Mymensingh district and to understand the infected environment in appropriate ways for saving the farmed fish stock.

Methodology:

Selection of study area and fish farmers: Data were collected through questionnaire survey from 15 aquafarms located in 3 Upazila under Kishoregonj district (viz., Kishoregonj sadar, Kotiadi and Pakundia) and another 15 aquafarms located in 3 Upazilas under Mymensingh district (viz., Isharganj, Nandail and Gouripur). Five farmers from each Upazila (a total of 30 farmers, 15 from Kishoreganj and remaining 15 from Mymensingh district) were selected after successful discussions with the Upazila Fisheries Officers (UFOs). Data collection method: To collect data, a set of questions was organized following a sequential and required logical format. Data collection method was divided into four steps i.e. (i) Questionnaire interviews, (ii) Focus group discussion, (iii) Cross check interviews with key informants, (iv) Observation of the farm area. Focus group discussion (FGD) was conducted with fish farmers. Crosscheck interviews were conducted with key informant such as District Fisheries Officer (DFO), Upazila Fisheries Officer (UFO), Youth Development Officer, Fisheries Extension Officer (FEO) and NGO workers working with aquaculture. Prior to field survey, background information on the number, location and distribution of fish farms and aquaculture activities were collected. Data analysis: All collected data were analyzed using "Microsoft Excel 2010". The summary tables were prepared to fulfill the objectives of this study. The results were shown in descriptive tabular and graphical presentation.

Achievement/Findings:

The results showed that pond water were not exchanged properly during culture period in Kishoreganj and Mymensingh districts. Farmers of Mymensingh compare to Kishoreganj, mostly exchanged water when needed as they had training and better experience in aquaculture that helps to maintain water quality and dissolved oxygen in their ponds. In Kishoreganj, only a few farmers measured water quality parameters while in Mymensingh majority of the farmers measured water quality parameters of their ponds on monthly basis. It was observed that in Mymensingh, most of the farmer removed pond bottom waste and dried their culture ponds after two or three cycle of production. On the contrary, only a few farmers in Kishoreganj removed their pond waste because of having larger size of ponds. Again, wearing disinfected clothing and boots by visitors and employees can prevent the horizontal transmission of infection vectors in fish farms (FAO 2007). Additionally, disinfected protective clothing and boots, and the use of footbaths and hand sanitation, are effective personnel biosecurity measures that considerably reduce the transmission of pathogens (Pollard et al. 2008). In the present study, it was found that farmers did not provide protective clothing and boots for visitors and their staffs before entering into the farm. Actually, farmers did not follow biosecurity measures due to lack of proper idea and training regarding these issues. Due to lack of proper knowledge, most of the farmers of both districts did not disinfect the equipment like nets, buckets, hapas, plastic bowls and other essential utensils. They did not also disinfect the vehicles and water distribution channel.
