Abdullah Al Asek | University of Chittagong (original) (raw)
Currently working as a research associate at Halda River Research Laboratory under the University of Chittagong, Bangladesh. Apart from this, I have created a website named bicchu.org with an aim to describe animals and to promote scientific study in our mother tongue, Bengali. I am working to build up a community based on this bicchu.org for creating awareness amongst general people in order to conserve animals and wildlife.

The study was conducted from Sattar Khal and ended at Karnafully confluence which covers almost 22 kilometers of area. A total of 6 boat-based surveys, 3 trips in 2019 and 3 in 2022 were conducted for making the dolphin estimates within the study area and a total of 112 dolphins were recorded in 2019 and 162 dolphins were recorded in 2022 which indicates an increase in the dolphin population in the Halda River. In 2019 the highest monthly count was in July of a total of 137 dolphins and in 2022 the highest monthly count was in February of a total of 167 dolphins with best-high-low estimates were 29-27-25 and 43-41-45 in July 2019 and February 2022 respectively in the river from the Chayar Char area. The density rate in the entire Halda River was 1.38/km and 2.00/km in 2019 and 2022 respectively. But in the study area, the density of the population was 5.09/km and 7.37/km respectively. These rates are fairly high when compared with any other areas of dolphin distribution in Bangladesh.

Halda is declared as the Bangabandhu Fisheries Heritage due to the broader support for movement towards its conservation. Discrete studies addressed water quality, land-use changes, ecosystem valuation, etc. without taking an integrated heritage conservation approach. This study aims to elucidate priority policy interventions for its integrated management by mapping significant constraints against Halda conservation. Published journal articles, newspaper reports, and reports on Halda from different organizations served as secondary information sources. Primary data were collected using structured questionnaires from 132 respondents from the egg collectors, tobacco farmers, and the rubber dam irrigation project users living in three Upazilas adjacent to the Halda River-Manikchhari, Hathazari, and Raozan. Key informant interviews were taken from the professionals of government and non-government institutions and researchers. Egg collectors appreciated the Upazila administration (65%) and the Department of Fisheries (48%) as effectively working institutions. Administrative bodies marked pollution (73%) as the main challenge in Halda conservation. Based on findings, recommendations were made which may assist the policymakers in developing strategies for integrated management of the river.
