Summary, etc. <p style="text-align: justify;">North-Eastern region of Bangladesh is very promising for freshwater capture fisheries, nevertheless, comprehensive assessment on faunal composition and diversity assemblages of natural wetlands are scant.This study identifies the occurrence, different biodiversity indices and composition of fish with various gear types by means of qualitative and quantitative approaches in Tanguar<em>haor</em> and Dekar<em>haor</em>. A total of 75 fish species were identified, of which 53 % were Cypriniformes, followed by Siluriformes (15 %), Perciformes (14 %), Channiformes (7 %) and Clupeiformes (4 %). Among the identified taxa 42 species were not threatened, 12 vulnerable, 11 endangered and 8 critically endangered. The values of diversity indices explicitly Shannon-Weiner (<em>H'</em>), Pielou evenness (J'), Margalef richness (d) and Simpson dominance (c) indices indicated that Tanguar<em>haor</em>wasmore diversified and evenly distributed than Dekhar<em>haor</em>. For effective management of the <em>haors</em>comprehensive stock assessment, establishment of fish sanctuaries, and combination of input and output control is suggested.</p>
