Research of Freshwater molluscs and bivalve of Turag river in bangladesh

Abstract

Bivalve molluscs are key components of the estuarine environments as contributors 

to the trophic chain, and as filter –feeders, for maintaining ecosystem integrity. 

Further, clams, oysters, and scallops are commercially exploited around the world 

both as traditional local shellfisheries, and as intensive or semi–intensive farming 

systems. During the past decades, populations of those species deemed of 

environmental or commercial interest have been subject to close monitoring given 

the realization that these can suffer significant decline, sometimes irreversible, due 

to overharvesting, environmental pollution, or disease. Protozoans of the 

genera Perkinsus, Haplosporidium, Marteilia, and Bonamia are currently recognized 

as major threats for natural and farmed bivalve populations. Since their identification, 

however, the variable publication rates of research studies addressing these 

parasitic diseases do not always appear to reflect their highly significant 

environmental and economic impact. Here we analyzed the peer– reviewed literature 

since the initial description of these parasites with the goal of identifying potential 

milestone discoveries or achievements that may have driven the intensity of the 

research in subsequent years, and significantly increased publication rates. Our 

analysis revealed that after initial description of the parasite as the etiological agent 

of a given disease, there is a time lag before a maximal number of yearly 

publications are reached. This has already taken place for most of them and has 

been followed by a decrease in publication rates over the last decade (20– to 30– 

year lifetime in the literature). Autocorrelation analyses, however, suggested that 

advances in parasite purification and culture methodologies positively drive 

publication rates, most likely because they usually lead to novel molecular tools and 

resources, promoting mechanistic studies. Understanding these trends should help 

researchers in prioritizing research efforts for these and other protozoan parasites, 

together with their development as model systems for further basic and translational 

research in parasitic diseases.

Introduction

Bangladesh is a riverine country. So it has a vast freshwater areas, including several 

inland water, there tributaries and sea area. Although freshwater of Bangladesh 

abound with a large variety of fish, systematic position of these fishes has not been 

adequately studied in the past, especially from the point of view of modern 

The estuarine is quite extensive. There are an estimated 43.37 lakh ha inland water, of 

which 40.5 lakh ha open waters i.e. rivers, canals, beels, haors, flood plains etc. and 

1.5 lakh ha  of closed water bodies including ponds and tanks, about 1.4 lakh ha of 

shrimp ghers in the coastal region. There is an area of 1.66 lakh square-km of marine 

waters, including territorial and economic zone (BFRSS, 1986).

The ecosystem of tropical and subtropical region supports a large variety of fishes 

which provides an important source of protein to the community and source of 

income. Among freshwater fishes snake headed fishes are regarded as a valuable food 

because their flesh is claimed to be rejuvenating and easy source of protein to general 

people having a wide range of geographical distribution.

In the economy, the role of fishery of Bangladesh is quiet significant. It provides 

nutrition, income generation, employment and exchange earnings. Providing an 

estimated 12 lakh eiadeshis directly and one crore indirectly. Fisheries sector 

contributed 4.43% to national GDP and 22.21% to the agricultural GDP and 2.73% to 

foreign exchanges by exporting fish products in 2010-11 (DOF, 2013). Fish provides 

60% of national animal protein consumption. This section contributes 4.7% of GDP 

12% of foreign exchange earnings. It provides 10% of the country’s labor force with 

1.4 million full time professional fisherman and 11.0 million part time fisher folk.

Parasitology has emerged as a science in its own right from parasitology. Parasites 

occupy definite position in the animal kingdom for remarkable adaptation and come 

from every phylum together form interspecific interaction called “Parasitism”. The 

composition of the parasites depends on various environmental factors such as: 

geographical location of the habitat, season of the year, physicochemical parameters

Assignment on Bangabandhu Safari Park Gazipur

Introduction:

A safari park is a wildlife parkland area or zoo-like commercial tourist’s attraction where visitors can drive in their own vehicles or ride in vehicles provided by the facility to observe freely roaming animals. A safari park is larger than a zoo and smaller than game reserves. Safari park is a declared protected area or In-situ conservation area where the animals are kept in fairly large area with natural environment and visitors can easily see the animal whenever they visit by bus, jeep or on foot. The safari park first opened in 1966 and continues to play a major role in the world programme of the breeding and conservation of endangered species.

Bangabandhu Sheikh MujibSafari Park, Dulhazra, Cox'sbazar  is the first Safari Park in Bangladesh. The nature of the forest is tropical evergreen and rich with Garjan, Boilam, Telsur and Chapalish along with herbs, shrubs and creepers.

 Safari Park is a declared protected area where the animals are kept in fairly large area with natural environment and visitors can easily see the animal whenever they visit by bus, jeep or on foot. This park was established on the basis of South Asian model.

Many tourists visit India, Nepal, Thailand, Indonesia or African countries to experience jungle environment. Now, you don’t need to go there. Bangabandhu Sheikh Mujib Safari Park of Gazipur is enriched with such kind of thrill.
