“…Availability of marine and coastal water with optimal salinity and temperature conditions are well suited to mud crab farming in the mangrove forests of Sundarban area and coastal districts in Satkhira, Khulna, Bagerhat and Cox's Bazar regions. Mud crab farming is playing a significant role in the livelihoods of coastal communities in Bangladesh (Basu and Roy 2018). Crab is less susceptible to disease and more resistant to adverse environmental conditions and the effects of climate change.…”

Development of a blue economy is firmly embedded in the development plans of Bangladesh. Advances in freshwater aquaculture have promoted Bangladesh to the fifth largest fish producer in the world. However, the marine resource base of Bangladesh, which is now even greater following the recent settling of disputes regarding maritime boundaries with neighbouring countries, lends itself to the development of marine aquaculture—known as mariculture. Several potential areas and opportunities for mariculture development have been identified for implementation under the concept of blue economy development in Bangladesh. We identify the most promising fish species as the hilsa shad (Tenualosa ilisha), seabass (Lates calcarifer) and the grey mullet (Mugil cephalus), and the shrimp species as black tiger shrimp (Penaeus monodon), brown shrimp (Metapenaeus monoceros), Indian white shrimp (Penaeus indicus) and the mud crab (Scylla serata). Further, some non-traditional marine species like seaweed, microalgae, shellfish (mussel, oyster) and the sea cucumber offer considerable potential. However, there remain major challenges and constraints that need to be addressed in order for mariculture to further develop and contribute to a growing blue economy in Bangladesh. Most notably, ministries, departments and research institutions, along with interested private entrepreneurs, must collaborate to formulate strategies for effective development and implementation, so that mariculture can contribute to food security and economic development through export opportunities.

“…Mangroves' crabs are initially harvested in the wild (Agbayani, 2011;Mirera, 2011;Quinitio, 2017;Hasanuzzaman et al, 2014;Basu and Roy, 2018). Mangroves provide a high level of salinity and temperature and protect young against cannibalism and predators, which is why these species thrive in these areas (Baylon, 2010;Alberts-Hurbatsch et al, 2014).…”

Mangrove crab Scylla serrata is associated with mangroves throughout the Indian and Pacific oceans. This species is crucial to aquaculture and fishing. As wild stocks decline and demand rises, mangrove crab aquaculture has become increasingly popular. However, feed development research and its quality are still meager in the industry. This study examined the interactive effects of different levels of crab shellmeal (CSM) to fishmeal (FM) replacement on proximate composition, feed utilization, carcass composition, growth, and survival performance of mangrove crab S. serrata. Four formulated diets were prepared, and one for chopped trash fish (TF) supplement: 30% FM and 0% CSM (Diet 1) as a negative control, 20% FM and 10% CSM (Diet 2), 10% FM and 20% CSM (Diet 3), 0% FM and 30% CSM (Diet 4), and TF as a positive control (Diet 5). Experiments were conducted in each group for 30 days with ten replicates. Results revealed that formulated diets using different levels of CSM and FM did not significantly affect mangrove crabs' growth and survival rates as well as feed utilization. However, the proximate composition of Diet 4 was significantly higher among other experimental diets. Moreover, the crab's whole body composition (ash, moisture, carbohydrates, crude protein, crude fat, and calories) with different levels of CSM and FM was significantly improved. Hence, it is possible to enhance the carcass composition and proximate composition by supplementing CSM; however, it has no effect on feed utilization, as well as the growth and survival rates of mangrove crab S. serrata.
