An experiment on culture of edible oyster ( Saccostrea cucullata) and green mussel (Perna viridis) was performed at Gangamoti estuary in Kuakata, Bay of Bengal coast of Bangladesh from December 2021 to March 2022 to fnd out the appropriate culture method of the oyster, S. cucullata and green mussel, P. viridis . Initially, the average shell heights of S. cucullata and P. viridis were 8.8±1.62 and 6.9±1.89 cm, respectively; where average weights were153.4±13.23 and 84.78±11.78 g, respectively. After the culture period, oysters shell height and weight grew up to 9.1±1.98 cm and 163.2±12.54 g, respectively in rectangular basket and 8.9±1.45 cm and 157.2±11.31 g, respectively in velon screen bag. In case of oysters, the rectangular basket and velon screen bag displayed the minor progress in specifc growth rate, 0.09±0.01 and 0.07±0.03, respectively. But green mussels did not show any growth rate. Oysters cultured in rectangular basket showed total mortality at day-90 and velon screen bag at day-75. Green mussels showed 100% mortality within 21 days of culture. Our experiment was the frst attempt to culture these two mollusks in the Kuakata coast of Bangladesh. However, further intensive researches would be required to evaluate the culture feasibility of these two mollusks’ species in the Kuakata coast of Bangladesh. ©2023 Agriculture and Environmental Science Academy Keywords Bivalve Rectangular basket Specifc growth rate Velon screen bag Citation of this article: Khan, A.

Mol- lusk can breathe through their gills and being flter feeders, they have a pivotal role to play like an aquatic engineer (Barman et al., 2022). Bivalve mollusks are very signifcant to aquatic and marine ecosystems by giving asylum to many creatures. Many countries of the world are dependent on the oyster industry to boost their national economy (Vakily, 1992). The ripple in cogni- tion has been imputed to this genre skill to boost food safety (Asare et al., 2019; Osei et al., 2020). Oysters can be traced in the coastal waters of temperate, sub-ecliptic and ecliptic areas (Grabowski et al., 2008). There are many ecological processes that oysters are pursuing as ecosystem manager (Alexandra et al., 2010). Bangladesh empowers with bays and several estu- aries that have the suitability for oyster aquaculture and can supply animal protein for poor people (Hasan et al., 2021). They are deliberated as remarkable species that provide residence, harbor and rations and are worthy tools for the waning brackish water biological community (Sanjeevraj, 2008). For oyster cul- ture, the oyster spat is the main factor and can be recruited ORIGINAL RESEARCH ARTICLE
