Establishment of a fish sanctuary for conserving indigenous fishes in the largest freshwater swamp forest of Bangladesh: A community-based management approach

A review of fish diversity, decline drivers, and management of the Tanguar Haor ecosystem: A globally recognized Ramsar site in Bangladesh

“…It was done by another project named the ‘Community Based Sustainable Management of TH (CBSMTH)’, especially to make out the fish resources status of the TH and its adjacent beels ( Alam et al., 2015 ). Since the fish sanctuaries serves as an integral part of the conservation process ( Kunda et al., 2022 ), five distinct fish sanctuaries were constructed in this haor under the CBSMTH project in 2011 ( Ahmed, 2013 ; Alam et al., 2015 ). Among them, four sanctuaries were established in four distinct beels , and one more fish sanctuary was recognized in the Patlai River’s Alamer Duar.…”

Impacts of brush pile fishing on fish biodiversity: A case study of the Shari-Goyain River in Bangladesh

“…Various katha materials were used in katha , such as bamboo, branches of trees, etc. which make it a temporary shelter where fish can take shelter, and be used as a feeding, breeding, and nursing ground ( Uddin et al., 2015 ; Sharma et al., 2014 ; Joadder et al., 2016 ; Kunda et al., 2022 ). Katha materials acted as substrates for periphyton growth, which is used as fish food.…”

“…As of now, this is more of a preliminary description of katha fishing and the biodiversity associated with a fished katha. However, it provides the message that to conserve species diversity in the river, katha fishing should be stopped or converted into permanent fish sanctuaries ( Kunda et al., 2022 ).…”

A long-term ichthyoplankton monitoring program suggests climate-induced environmental variabilities changed fish communities in the Hudson River estuary

“…A Margalef index (d) was used to examine the changes in species richness for the two groups of E&L and Y&O in the upper and lower HRE. A Margalef index assesses the number of identified species taking into account the effects of sample size (Margalef, 1968;Garcıá-Seoane et al, 2016;Kunda et al, 2022):…”

“…A Simpson index (D all ) was used to evaluate species diversity taking into account the abundance of each species. It measures species evenness, giving more weight to abundant species (Simpson, 1949;Garcıá-Seoane et al, 2016;Kunda et al, 2022): where n = the number of individuals of a species, and N = the total number of individuals of all species. The Simpson index was used for examining if there is increasing or decreasing establishments of fish species over the two phases.…”
