Abstract
To understand the effect of post-harvest good handling practices on prawn(Macrobrachiumrosenbergii) quality, data were collected from stakeholders involved indistribution chain by semi-structured questionnaire, focus group discussion and transectwalking at Kishoreganj and Mymensingh. Most used containers were split bamboo basket(39%), split bamboo basket with polythene lining (18%), plastic crate (12%), styrofoamcrate (8%) and rectangular metal container (12%). 15%, 25%, 10%, 100% and 7% largeprawns were water washed and 9%, 35%, 22%, 100%, 60% large prawns were icedimmediately after harvest, later in fishing trip, immediately after landing, at wholesalehouse before transportation and during retail sale, respectively. Bacterial counts of waterused for ice preparation, ice crushed mechanically and on soil floor collected from BhairabBazar and Karimganj were 6.58±1.87×103, 4.77±0.19×102, 4.12±2.06×103 cfu/ml and4.82±1.56×102, 6.01±1.61×101, 6.90±1.61×102 cfu/ml, respectively. Ice melted watercollected after unpacking prawn containers at Mymensingh, transported from BhairabBazar and Karimganj, had 5.90±1.95×107 and 6.32±2.06×108 cfu/ml bacterial counts,respectively; indicated unhygienic handling environments. However, existing post-harvesthandling practices produce prawns acceptable for consumers as sensory assessment forprawns showed the quality defect points of 1.0 (Excellent), 2.1 (Good), 2.3 (Good) and 2.9(Good) at harvesting, landing, wholesale and retail shop, respectively.

Highlights
Global fisheries and aquaculture production peaked at about 171 million tons worth of USD 362 billion in 2016 (FAO, 2018)
In 2018, 0.25 million metric ton prawn and shrimp was produced in Bangladesh from inland capture and culture sector (DoF 2019)
Microbiological quality and sanitary condition assessment of prawn handling At every two months interval during 6 months study period, water used to prepare ice, ice crushed by mechanical ice crusher and by hammer on soil floor from Karimganj and Bhairab Bazar and ice melted water from Boro Bazar after unpacking of prawn container transported from Karimganj and Bhairab Bazar were sampled from two different sources with three replications
Summary
Global fisheries and aquaculture production peaked at about 171 million tons worth of USD 362 billion in 2016 (FAO, 2018). Total fish production in 2018 was 4.2 million metric ton, which contributed 3.50% of total GDP, 25.71% of agricultural GDP and earned USD 5.07 billion foreign currency, establish ‘Fisheries’ as the second largest export sector of Bangladesh (DoF 2019). In 2018, 0.25 million metric ton prawn and shrimp was produced in Bangladesh from inland capture and culture sector (DoF 2019). Mymensingh and Kishoreganj are among the major prawn culture and production areas of the country. Kuliarchar of Kishoregonj district is one of the major freshwater fish landing centers of the country. Fishes and prawns of haor fisheries of Kishoregonj, Sunamgonj, Sylhet and Mouluvibazar districts are landed in Kuliarchar from where a significant portion is exported to Europe, USA, Japan and Middle-East (Nowsad et al, 2010)
