Abstract/ Executive Summary:

The study was carried out to know the purpose of the use of chemicals and current status of chemicals used in various aquaculture activities in Shyamnagar upazila between August 2007 and February 2008. A total of 50 shrimp farmers and chemical sellers were selected for questionnaire interview. Data were collected through PRA tools like questionnaire interview, Focus Group Discussion and key informant interview. All interviewed farmers were male with an average age of 36-45 years and their average family size was 7 members. Commonly used chemicals found in the study area were lime, urea, Triple super phosphate (TSP), Potassium permanganate, Vitamins, Antibiotics, (mainly oxytetracycline and chlorotetreacycline), rotenone, phosphate, phostoxin, sumithion, melathion, timsen, bioaqua, oxymax/oxyflow, aquanarish, aqua clean and théoden. Health management and disease treatment were the major activities where farmers were seen to us e a lot of chemicals. Study identified some diseases and conditions like white spot disease, yellow head disease, heavy gill and surface fouling disease, brown spot disease, nutritional disease and environmental disease. This study demonstrated that most of the farmers used chemicals and antibiotics indiscriminately without knowing their mode of action, doses and appropriate procedure of application. Study also shows that farmer used various types of chemicals but did not get benefit only little exception due to shrimp viral disease. The study also highlighted the names and approximate price of aquaculture chemicals available with the chemical sellers in the study areas.

Start Date: 00-08-2007

End Date: 00-02-2008

Program Area: Animal Health and Management

Commodity: Shrimp

Objectives:

To realize the seriousness of shrimp health problems and the importance of shrimp health management.

Methodology:

Most of the shrimp ghare are situated in south-western part of Bangladesh. Satkhira is the most important and promising area for shrimp (galda and bagda) farming because of availability of wild post-larvae in costal belt. A total of 50 shrimp farmers and chemical sellers were selected for questionnaire interviews in selected areas. PRA is a group of method to collect information from target grouping a participatory fashion. The advantage of PRA over other methods is that through wide participation of the community, the information collected is likely to be more accurate. The participation of retailers provides an opportunity for cross checking individual option as well as allowing the community to discuss the issues that they fell important, rather than responding to a questionnaire. For the present study, PRA tool such as one to one questionnaire interview, focus group discussion (FGD), cross check interview etc. were conducted with retailers. The data collection as well as field survey was under taken for six months from August 2007 to February 2008 in selected areas. Data were collected by direct one to one interview with Shrimp farmers and chemical seller who were selected randomly; time required for each interview was about 1-1.5 hours, and crosscheck interview with key informants to verify the information from questionnaire interviews with different NGOs who were working in that resign and Thana Fisheries Officers (TFO). Also Focus group discussions (FGD is a discussion meeting with a selected group of retailers to follow a set of detailed guidelines designed to generate information on a particular set of topic) were held with the group of shrimp farmers (each group size was 6-12 retailers) to collect accurate information. After collection, the data were edited carefully to eliminate possible errors and inconsistencies. Then it was transferred to a computer (MS Excel) after careful examination and checking of the information. The processed data were finally analyzed to produce grapes by using Microsoft Excel.

Achievement/Findings:

Health management and disease treatment were the major area of aquaculture. Since farmers used a lot of chemicals in disease management, an attempt was made to have farmer’s perception about shrimp diseases in their systems. Some problems are of the use of chemicals by the farmers which include lack of knowledge of the chemicals, doses, methods of application and abuse of chemical. There is a badly need for better understan ding of shrimp farm health management and disease prevention practice that could reduce the need for chemical treatments. Judicious use is essential to keep this tool effective.
