Title : Effect of harmful agent on production income and biodiversity of shrimp farming in Bangladesh
Abstract:
Shrimp is one of the leading exportable seafood products from where Bangladesh 2017-2018 financial year exported 36168 MT product and its value is 40 core 87 lac USD which yearly contributing 3.57% to the GDP. Research was conducted in three Upazila (Kaliganj, SyamNagar Asasuni) under Sathkira district the southwest reason of Bangladesh. Three different farming practices organic, traditional and control/ extensive farmer were selected for the research. Farmer follows the traditional and control extensive farming practices and average production is 275 kg/ha which is the lowest compared to other countries producing shrimp around the world. Reasons of this low production are lack of better technology, dearth of quality seed & feed and effect of shrimp disease. Small-scale organic shrimp farming practice introduced recently has shown better production and profitability under three coastal sub district (Upazila) of Sathkira district in the southwest part in the country. Three different farming practices were studied (i) organic (ii) traditional and (iii) control/extensive farming where farmers were interviewed to collect data. In comparison to the production kg/ha/yr from the year 2012 to 2014, the highest production occurs in organic shrimp farming than others. Organic Shrimp farming production is 13.16% higher than the traditional and 15.14% higher than the control/extensive shrimp farming. Traditional shrimp farming production is 1.98% higher than the control/extensive shrimp farming. The result shows that highest income ha/yr. in organic shrimp then traditional and lastly control/extensive shrimp in total of year from 2012 to 2014. Percentage of gross sell of organic is 14.01% higher than traditional and 15.89% higher than the control/extensive shrimp farming. The traditional shrimp gross sell is 1.87% higher than the control shrimp. Interview and PRA method were used for the collection of data. The main research question was what effect dose the overall production, income and biodiversity among the three different farming practices. Effect were found that production kg/ha is organic higher than traditional and control/ extensive shrimp farming practices. Traditional farming production cost is higher than the organic and control/ extensive farming practices. Considering to the biodiversity organic farming conserve more biodiversity than traditional and control/extensive farming practices.
Compare to the organic, traditional and control/extensive farming practices, organic is sustainable and environmentally friendly farming system. Organic farming is less input cost and higher production and high product value. Organic farming protects the environment and biodiversity. Organic farming could be creating the international image of Bangladeshi product in the international market
Key wards: Organic, Traditional, Extensive Shrimp farming, production, income biodiversity.
