Bangladesh is a maritime nation situated on the northern side of the Bay of Bengal (BoB), blessed with substantial natural resources and opportunities. However, natural disasters and climate-induced hazards are threatening these opportunities as well as destroying the recourses. Coastal vulnerability assessment aids in the prevention of loss of lif...

Illegal, unreported, and unregulated (IUU) fishing can result in loss of revenue, environmental damage, and economic loss for coastal communities, as well as a reduction in fish stocks. This study aims to generate comprehensive knowledge of the historical patterns and current status of IUU fishing in the coastal and marine waters of Bangladesh (BD)...

Abstract This study aims to explore the variation of Chlorophyll-a (Chl-a), particulate organic carbon (POC) and sea surface temperature (SST) before (pre-cyclone) and after (post-cyclone) the cyclone Amphan in the Bay of Bengal (BoB). Moderate Resolution Imaging Spectroradiometer (MODIS) Aqua satellite level-3 data were used to assess the variabil...

This study was carried out at mangroves and saltmarsh area of Cox's Bazar, Bangladesh which is called a nursery, spawning & breeding ground of horseshoe crabs (HSC) for a period of July 2021 to June 2022 to reveal the morphometric variability in different sex of the adult mangroves horseshoe crab (Carcinoscorpius rotundicauda). The morphometric var...

The COVID-19 pandemic has profoundly affected many world regions’ coastal social-ecological systems (SESs). Its extensive consequences have exposed flaws in numerous facets of society, including small-scale coastal fisheries in developing countries. To this extent, by focusing on two coastal districts in Bangladesh, namely Chittagong and Cox’s Baza...

Living marine resources are limited; therefore, utilizing them sustainably is essential. Not all resources obtained from the sea are used adequately, causing discards, on-board waste, and by-products and waste on land. Recognition of the limited marine resources and increasing environmental pollution has emphasized the need for better utilization o...

This study examined daytime and nighttime sea surface temperature (SST) and its diurnal variability (D-SST) in three regions of the northern Bay of Bengal (BoB) during 2000–2019 by using MODIS Terra satellite data. An increasing trend of SST was observed in the Bangladesh coast, outer coast, and offshore. The trend was ranged around 0.10–0.16 °C pe...

The Bombay duck (Harpadon nehereus) forms the second-largest single-species marine fishery in Bangladesh and therefore has a significant impact on the local economy, providing employment , food, and nutrition to thousands of people. Despite the immense importance, this fishery has never been a priority for the relevant regulatory authorities. To en...

Bangladesh acquired a large maritime area(1,18,813 km2) which is almost the same as its land area; therefore, this vast marine area provoked Bangladesh to use its maritime resources in a sustainable way called this term "Blue Economy". For implementing "Blue Economy" in the marine area a proper ocean management tool is required; unfortunately, Bang...

The importance of recreational fishing, in many coastal areas and less developed nations, is increasing rapidly. Connecting fisheries to tourism can create innovative tourism products and provide new income sources. The present study is the first to explore the concept of coastal fishery-based ecotourism (FbE) to enhance the social-ecological resil...

Fisheries assemblages with notes on the ecological conditions in coastal waters of the northern Bay of Bengal, Bangladesh, were investigated based on a one-year cycle (2015-2016) data collected by beach seine net. A total of 75 species consistent of 61 finfishes, 7 shrimps, 2 cephalopods, 2 lobsters and 3 crab species were identified. Among them, 5...

Recreational fishing trips constitute a significant part of the tourism business in many countries. Linking fisheries to tourism can be both a response to the need to create innovative tourism products and the need to find new sources of income for fisheries to make them more profitable and sustainable. This leads to the question of whether Banglad...

Zooplankton play an important role in aquatic food webs by fluxing of energy from primary producer to subsequent trophic levels in the food chain. The annual pattern of zooplankton communities and potential environmental drivers were studied in the Kohelia channel, Bangladesh from summer 2014 to spring 2015. Samples were collected using net at a de...

Zooplankton are a primary component of aquatic food chain and play an important role in the functioning of aquatic food webs. Seasonal variation in community structures of zooplankton and potential environmental drivers were studied, during a 1-year cycle (summer 2015 – spring 2016) in subtropical maritime channels systems in the Bay of Bengal, coa...

Macrobenthos play an important role in the functioning of benthic food webs in intertidal soft-bottom sediments and commonly used as potential biomarkers for coastal ecosystems. The seasonal variation in community structures of macrobenthos was studied in northern Bay of Bengal, Bangladesh from summer 2015 to spring 2016. A total of 45 species belo...

In this study, the assemblage structure of nektonic fauna were studied in relation to some important environmental variables in the Meghna Estuary, the largest estuarine ecosystem of Bangladesh. Silica, nitrite, phosphate, and total suspended solids (TSS) were found to be positively correlated with fish species abundance. Nitrite and TSS showed sig...

Mixed Layer Depths (MLD) on the basis of temperature and density were calculated for the Bay of Bengal area. Long term archive data from World Ocean Database (WOD09) were used for calculating MLD in the study area. During the pre monsoon period the lowest thermal MLD was observed in the mid basin area with a value of 25 m. But within the monsoon pe...

Water, nutrient and Salt transport through the lower Meghna River-estuary, a combined flow of the Ganges and Brahmaputra and many other rivers and creeks, were studied. Material (salt, water and nutrients) fluxes covering an area of about 532 km(2) were calculated. Present study consists a single layer simple box model to study the budget of the ma...

Karnaphuli river originates in the Lusai hills of Assam, India and empties into the Bay of Bengal through the north-eastern part of Bangladesh. During its course through Bangladesh it is dammed for hydroelectric power generation forming an artificial hillbound lake. At the downstream reaches, it receives water from two major perennial tributaries a...

Water, Nutrient and Salt transport through the lower Meghna estuary, a combined flow of the Ganges and Brahmaputra and many other rivers, was studied. Despite a very complex network of rivers and channels, a simple approach of measuring these parameters for an annual cycle during premonsoon, monsoon and postmonsoon seasons covering an area of about...
