Abstract/ Executive Summary:

The investigation was conducted on the present situation of fish biodiversity and abundance of fish fauna at two different points of Madhumati River at Mohammadpur upazilla under Magura district from October 2018 to September 2019. A total of 83 species of fresh water fish species were recorded belonging to 58 genera of 28 families under 11 orders. Cypriniformes was recorded as the dominant order comprising 26 species constituting 31% of the total. According to IUCN 59% of fish species were Least Concern, 12% were Vulnerable, 11% were Endangered, 9% were Near Threatened, 1% of each were Data Deficient and Critically Endangered locally, and 7% Exotic fish species were also enlisted. Annual value of Shannon diversity index (H) was 1.974 and Sipmson diversity index (λ) was 0.272 which indicate highest diversity of fish was in March. Annual Margalef’s richness index (D) was 6.654 and Pielou’s evenness index (E) was 0.447 denote highest richness was in November and evenness was in March. The river was found to have moderate type of diversity in terms fish species composition.

Location: Madhumati River at Mohammadpur Upazila under Magura district

Start Date: 00-10-2018

End Date: 00-09-2019

Program Area: Resource Development and Management

Commodity: Fauna

Objectives:

Hence, there is necessity to update the species checklist of fish available in the Madhumati River and present status of the fish and their diversity, richness and evenness in the river. This exploration was aimed to build up authentic information about the species available at the Madhumati River in south-west part of country.

Methodology:

The Madhumati River was selected for this study to assess the fish fauna and their current status. The fish samples were collected monthly from the river during October 2018 to September 2019. Two points were selected in Magura District at Mohammadpur Upazila, which were Elangkhali Ghat (23°24'29.7"N and 89°36'16.5"E) and Jhama Bazar Ghat (23°36'03.4"N and 89°57'94.3"E). Monthly fish samples were collected from the selected spots directly from the fishermen, retailers, ‘Nikari’, ‘Bapari’ and ‘Aratdar’ from the two preselected sites. Some fishes were directly identified in the sampling spots and rest of the fish specimens were carried in ice box or safeguarded in 4 to 6% buffered formalin solution to the Fisheries Laboratory, Department of Zoology, Jagannath University for identification and further taxonomic study. Large fishes were easily counted and recorded but small fishes were counted using the following formula:

Ns= Ns x Wt/Ws

Where, N is the total number of a fish species, Ns is number of individual small fish in each subsample, Wt is the total weight of small fish found in the sample and Ws is weight of subsample. Fish species were identified based on their morphometric and meristic characters following Fish Base (2020), Rahman (2005), Talwar and Jhingran (1991) and Bhuiyan (1964). Identified fishes were systematically arranged according to Nelson (2006). Fish status were categorized according to IUCN Redlist (2015, Volume 5: Freshwater Fish). Diversity, richness and evenness were calculated using the following formulae.

Achievement/Findings:

This is a preliminary and baseline study and have some limitations. A small part of the river was considered in this study which may not reflect the exact condition of the river. This study suggests the decline trend of the existing fish fauna and degrading the biodiversity. Extensive and complete study on this river along with social impact of local people may reveal the exact condition of the river.
