Abstract
Protein, lipid, ash and moisture content in the body muscles of two commonly available puffer fish species in Bangladesh (Leiodon cutcutia and Dichtomyctere fluviatilis) have been analysed from January 2018 to June, 2018. The puffer fish species were collected from different habitats i.e., Leiodon cutcutia from freshwater and Dichtomyctere fluviatilis from estuarine water. The percentage of the proximate composition varied in different months in both the species. In Leiodon cutcutia, moisture content fluctuated from 79.32% to 87.61% with an average of 83.75%; protein content from 6.35% to 13.31% with an average of 9.49%; lipid content from 1.57% to 2.32% with an average of 1.92% and ash content from 2.30% to 3.27% with an average of 2.84%. In Dichotomyctere fluviatilis, moisture content fluctuated from 73.77% to 84.18% with an average of 77.49%; protein content from 10.03% to 19.77% with an average of 16.80%; lipid content from 0.92% to 1.71% with an average of 1.32% and ash content from 2.77% to 3.34% with an average of 3.05%. The comparative evaluation of the nutritional value of the studied fish species revealed that the puffer fish from estuarine environment might contain higher amount of nutrients. Thus, proper utilization of this species towards sustainable management, nutritional composition and biosecurity issues will lead to achieve sustainable blue economy.

IntroductionPuffer fish (Patka mach) is a balloon-shaped fish of the family Leiodontidae, order Leiodontiformes
Bangladesh has huge potentials in terms of diverse marine fauna and is considered one of the most suitable regions for fisheries in the world, with the world's largest flooded wetland and the third largest aquatic biodiversity in Asia after China and India (Shamsuzzaman et al, 2017).Puffer fish (Patka mach) is a balloon-shaped fish of the family Leiodontidae, order Leiodontiformes

Summary
Puffer fish (Patka mach) is a balloon-shaped fish of the family Leiodontidae, order Leiodontiformes. The fish is able to inflate itself enormously with air like a balloon, and are found both in freshwater and marine environments. Among the puffer fish species, three species under two genera are commonly available in Bangladesh. Leiodon cutcutia has broad head and back, tapering abruptly at the tail. Upper part of the body is greenish yellow, abdomen white, body length is about 3 cm. The fish is found widely in the freshwater throughout the country. Dichotomyctere fluviatilis is slightly compressed bodied attains a length of about 12 cm with broad head and back, tapering abruptly to tail. Upper part of the body is olive green; sides and lower part white; there are black blotches on the back and sides. The fish is found in rivers and estuaries (Santini et al, 2013)
