“…On the other hand, a very small market structure, poor governance, buyer‐driven value chains, inadequate wild seed supply and poor quality feeding regimes were listed as the most important reasons for the sudden collapse of the soft‐shell crab industry in the Cox's Bazar region. These findings are similar to other studies, where disease outbreaks, poor market structure (Rahman et al, 2018), fragmented value chains, poor profitability, inadequate supply of products and poor policies have been identified as major reasons for the downfall of the seafood farming industry (Arquitt et al, 2005; Belton et al, 2017; Prusty et al, 2011). Protected zones for species (Prusty et al, 2011), creation of local demand (Belton et al, 2017), introduction of value‐added products and the expansion of new markets are the key issues that need to be addressed to increase the sustainability of the industry.…”

Mud crab is one of the most commercially important shellfish species in Bangladesh, ranking second after shrimp and prawn (in terms of export earnings) due to its high demand in the international markets (Rahman et al., 2017). Among the 15 crab species in Bangladesh, mud crab Scylla olivacea, previously known as Scylla serrata (Rouf et al., 2016), is the only commercially important crab species. It is abundant in coastal water bodies, including estuaries, tidal canals and rivers, the Sundarbans mangrove swamps, and shrimp ghers (i.e. low-lying agricultural fields with elevated surrounding embankments/borders created by the side of a river that are used for growing paddy in winter and shrimp in summer through to fall;Milstein et al., 2005

“…We have taken help of "system archetypes" to analyse the current model. System archetypes are existing and tested structures that facilitate in thinking and understanding system structures (Prusty et al, 2014;Prusty et al, 2017;Senge, 1990;E. F. Wolstenholme, 2003).…”

During such unprecedented time as COVID‐19, despite stretched to its limit, public service delivery remains crucial to societies' well‐being. Street‐level bureaucrats (SLBs), specifically, become the most visible outreach of public policies to citizen. However, as the literature suggests, unintended outcomes of SLBs–citizen interfacing have been discretion, inefficiency and accountability, an issue lies at the heart of the standard public governance. No scholarly attempt has been made in the past to address this shortcoming. This research by proposing a conceptual model using system dynamics captures the complexity, and in so doing posits testable hypotheses that instigate an alternative visualization of public affairs, thereby closing the gap in the SLB scholarship.
