Evaluation of ecosystem services of mangroves and their economic evaluation are yet unrevealed, although several literatures are available on the use of mangroves as nursery and breeding ground of fishes, sources of timber, honey, wax, firewood etc. Considering the importance of mangroves as primary service providers to coastal populations and island dwellers, it is extremely important to assess the condition of mangrove forest and relate the same with the anthropogenic and natural threats existing in and around the habitats. Relative abundance and Shannon-Weiner species diversity index of true mangrove species can be used as indicators of mangrove health. The present paper is an approach to evaluate the health of mangrove floral species considering 10 sampling stations in Indian Sundarbans during 2014. The mangrove patches in the selected stations were categorized into a 4-point scale depending on the values of Shannon-Weiner species diversity index. The health of the mangrove forest as per our constructed 4-point scale was found to be regulated primarily by anthropogenic factors, although in station like Sagar South, the natural erosion may be the key player in determining the mangrove floral diversity.

Water hyacinth (Eichhornia crassipes) is profoundly found in the water bodies of tropical countries. It is a menace as it chokes the water body, drainage system and kills the fishes because of oxygen depletion. The adverse impact of water hyacinth has been stated in several literatures. Apart from destroying the aesthetic value of the aquatic ecosystem, water hyacinth cluster serves as the breeding ground of several disease causing insects and pests. The species is also invasive in nature and out-compete all other aquatic species growing in its vicinity and thus decreases the biodiversity of the aquatic ecosystem. Considering this disadvantage spectrum of water hyacinth, the present research programme is a turning force to rotate the significance of water hyacinth from its disadvantage to an advantageous sector. It can be used as an agent of bioremediation because of its potential to absorb heavy metals in its body tissue. The present programme is an attempt to monitor Zn, Cu and Pb in the body tissues of water hyacinth collected from East Kolkata Wetland during November, 2014. The analysis was carried out through Atomic Absorption Spectrophotometer (AAS) after acid digestion. The order of metal accumulation is Zn > Cu > Pb.- Bioaccumulation Pattern of Cu, Pb and Hg in Dominant Mangroves in Indian Sundarbans Estuarine Region

Pollution by heavy metals in coastal area especially in mangrove ecosystem in Indian Sundarbans, the world heritage site, as a result of industrialization and urbanization is a serious threat for environmental safety. This study was carried out to assess the bioaccumulation pattern of three heavy metals (copper, lead and mercury) in four dominant mangrove species from Indian Sundarbans estuarine system, namely, Avicennia alba, Avicennia marina, Avicennia officinalis and Excoecaria agallocha in the year 2014. For this purpose leaves, ischolar_mains and stem samples were collected from 6 stations (viz., Chemaguri, Jambu island, Gosaba, Bali island, Sajnekhali and Bagmara) located in western, central and eastern estuarine sectors of Indian Sundarbans and analyzed for copper, lead and mercury content. The concentration of heavy metals was found in the order Cu > Pb > Hg in ischolar_main, stem and leaf of the four plant species. Significant variations of heavy metal concentrations were observed between species and between stations (p < 0.01) confirming that different species has different ability of bioremediation. The pattern of bioaccumulation in the four species was seen to follow the order as A. officinalis > A. marina > A. alba > E. agallocha in all the seasons. This result indicates that A. officinalis can be regarded as the most potent bioremediator of ambient water and sediment among the four selected mangrove species.- Notes on the Wasted Ichthyoplankton Due to Wild Harvest of Tiger Prawn Seed from Junput (East Midnapur District), West Bengal

Mangrove ecosystem in coastal West Bengal has increased the fish productivity of the state as it acts as the nursery of finfish juveniles and cradle of several species of shellfish. In West Bengal shrimp farming is being practiced in most of the saline pockets of the state as the major livelihood programme. To sustain this aquaculture, tiger prawn seeds are procured from the coastal water, estuaries and mangrove creeks. The ischolar_main of this ecologically adverse practice is basically related to high demand for prawn seeds by the coastal shrimp culture farms and absence of tiger prawn hatchery in the entire state of West Bengal. During the collection of prawn seeds several nontarget species (juveniles of several finfish and shellfish, other than tiger prawn seeds ) are trapped in the net. thrown away and wasted. This may pose an adverse impact on the pelagic and demersal fish reservoir in ecosystem The present communication aims to highlight this aspect at Junput located at East Midnapur district in West Bengal. From this area 37 species of finfish juveniles have been recorded, which are thrown ashore and wasted during the wild tiger prawn seed collections.- Culture of Penaeus monodon Using Plant Based Additives in Indian Sundarbans

Culture of Penaeus monodon occupies a dominating sector in Indian brackish water aquaculture and proper feed is the most important criteria in getting beneficial returns from shrimp culture. To evaluate the efficiency of feed, mixed with specially formulated plant feed additives with respect to shrimp growth, survival, production, feed conversion ratio and pond environment, experimental monoculture of Penaeus monodon (with stocking density 5 nos./m2), was carried out in two different islands (Chotomollakhali and Bali) of Indian Sundarbans. The shrimps were harvested at the end of 93 days and a production of 823.61 kg/ha and 952.20 kg/ha was obtained in the islands Chotomollakhali and Bali respectively.Keywords

Porteresia coarctata (= Oryza coarctata) is a perennial halophytic wild grass, relative of rice and member of the family Poaceae. It acts as a pioneer species in the succession process of mangrove formation along the estuaries of India. The sequestering carbon, fertilizer in aquaculture and salt tolerant property of this mangrove associate has been dealt with by a number of workers earlier. But, the present study was conducted to evaluate the antibacterial property of aqueous, acetone, ethanol and methanol extracts of Porteresia coarctata collected from the Matla river of Indian Sunderban delta. Collected sea weeds were screened for their antibacterial studies against gram positive bacteria including Staphylococcus aureus, Streptococcus fecalis and Bacillus subtilis and gram-negative bacteria including Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, Klebsiella pneumonia and Proteus vulgaris using disc diffusion method. Present study shows that ethanol extracts of Porteresia coarctata has maximum antibacterial activity against E.coli (1.2±0.01 mm) and Streptococcus fecalis (1.4±0.01 mm) at an MIC of 700 μg/mL and 500 μg/mL, respectively. Along with the antimicrobial activities, seaweeds also showed anti-diabetic activity and but have no anti-inflammatory activity. Therefore, the results suggested that these sea weeds could be exploited in the management of various infectious diseases and can be used as for pharmaceutical purpose.- Antibacterial Activity of Certain Ferns Against Multi Drug Resistant Organisms

Antibacterial activity of frond extracts of three ethno medicinal important ferns viz. Angiopteris helferiana C. Presl, Cyathea brunoniana (Wall. ex Hook.) C.B. Clarke & Baker and Pronephrium nudatum (Roxb. ex Griff) Holttum was assayed by well diffusion method against multi drug resistant organisms i.e., Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. The result revealed that the ethyl acetate frond extract of Cyathea brunoniana, Pronephriumnudatum were active against methicillin resistant Staphylococcus aureus while that of Angiopteris helferiana was active against only Staphylococcus aureus (ATCC 25923). The minimum inhibitory concentration of crude ethyl acetate frond extract of Cyathea brunoniana, Pronephriumnudatum was found to be 400 mg/ml against methicillin resistant Staphylococcus aureus. The synergistic activity of the crude extract with the antibiotics showed that the antibacterial activity of the antibiotics increased in synergy with crude extract of Cyathea brunoniana and Pronephriumnudatum respectively. Thereby, the results indicated the possibility of using the fern extract of Cyathea brunoniana and Pronephriumnudatum as a future treatment option against methicillin resistant Staphylococcus aureus.Keywords

Coastal zones are particularly vulnerable to climate variability and change. Key concerns include sea level rise, land loss, changes in maritime storms and flooding, responses to sea level rise and implications for water resources. The IPCC estimates that the global average sea level will rise between 0.6 and 2 feet (18 to 59 cm) in the next century. India has been identified as one amongst 27 countries, which are most vulnerable to the impacts of global warming - induced sea level rise. Any global warming-induced climatic change such as increase in sea surface temperature, change in frequency, intensity or tracks of cyclones, sea level rise may aggravate the potential risks to coastal zones and estuarine systems of the Indian sub-continent. The adverse impact of climate change on estuarine system stems from the fact that global warming may cause changes in the salinity level of the coastal and estuarine waters, the amount of , oxygen in the water, pollution level and turbidity levels due to increased frequency of erosion caused by amplified tidal amplitude.
On this background, an investigation was undertaken in the aquatic system of mangrove dominated Indian Sundarbans considering surface water temperature, salinity and dissolved oxygen as indicators. Possible adverse impacts on the human society due to such change have also been highlighted.

The marine and estuarine compartments are important components of our future generations. The biological productivity, taxonomic diversity and aesthetic beauty of this aquatic resource area of the planet Earth needs to be preserved for rational exploitation and sustainable use of its biotic and abiotic components. With the advent of civilization, the pace of industrialization and urbanization has increased exponentially which has posed a significant negative impact on the positive health of the marine and estuarine compartments. The spillage of oil in the aquatic phase of such compartments is a matter of great concern, as the entire food chain may get disturbed depending on the magnitude, nature and residence time of the spilled oil. The present paper highlights this im portant issue through some relevant studies.Keywords

In the last few decades, several scientific studies have revealed that the marine and estuarine environment is vulnerable towards various endocrine disrupting chemicals (EDCs). EDCs are structurally diverse group of compounds that may damage the health of humans, wildlife, fisheries and their progeny by the interaction with the endocrine system. EDCs encompass a wide spectrum of chemicals like pesticides (such as DDT, lindane and vinclozolin) and industrial chemicals (such as phthalates, bisphenol A and alkylphenols). These groups of chemicals have considerably adverse effect not only on the individual species, but also on the marine and estuarine biotic community. Several EDCs also bioaccumulate and biomagnify through food chain posing a great risk (mostly reproductive failure) to the top level members of the trophic level.- Interrelationship Between Hydrological Parameters and chlorophyll α Concentration in and Around Indian Sundarbans

Phytoplankton are minute, free floating, floral communities that are widely available in the marine and estuarine waters. They are totally dependent on nutrient availability, transparency, salinity and temperature of the water body. A comparative study was conducted to monitor the interrelationship between selected hydrological parameters (like surface water temperature, transparency, pH, salinity, dissolved oxygen, nitrate, phos phate and silicate) and chi α concentration at twenty different sampling stations in and around Indian Sundarbans during 2003 on seasonal basis. Significant positive correlation values were observed between salinity, pH and chl α, confirming high salinity and slightly alkaline pH to be extremely favourable for the growth and survival of the phytoplankton species in the present geographical locale. The importance of transparency in promoting the growth of phytoplankton has also been confirmed. The significant negative relationships between phytopigment (chl α) level and nutrient (nitrate and phos phate) concentrations of the ambient water confirm the necessity of nutrients as building blocks of marine phytoplankton. However an insignificant relationship was observed between chl α and silicate. This may be due to less abundance of siliceous diatoms in com parison to flagellates in the present study area.Keywords

Vitamin C, chemically known as ascorbic acid is an essential, water-soluble vitamin. Most mammals can synthesize vitamin C from glucose, but a few including human being cannot synthesize it within body system. Green fruits (citrus fruits) and vegetables are the rich sources of naturally occurring vitamin C. In plants, vitamin C accumulates during the ripening process and is presumably synthesized within the plant cells from naturally occurring glucose. Like terrestrial plants many mangrove plants are the rich source of vitamin C. Indian Sundarbans, at the apex of B ay of Bengal is situated in the north-eastern coast of the Indian sub-contincnt, which harbours a luxuriant mangrove vegetation. These very specialized vegetations play a vital role in maintaining the economic structure of the coastal population and are not only the source of timber, fire-ujood, honey, wax, alcohol, tannins and medicines, but also the fruits of mangrove species like Sonneratia apetala serve as potential natural reservoir of vitamin C, which i f properly utilized may fulfill the nutritional requirement of the coastal populations. The present paper is an attempt to highlight the vitamin C level of Sonneratia apetala fr u it under different condi tions of growth and cooking. It was documented that the vitamin C content in the fru it of Sonneratia apetala varies as per the order: green fruit > ripe fruit > boiled fruit > fruit ja m . The vitamin C content of Sonneratia fruit is very close to the citrus fru it orange and therefore, speaks in favour of proper utilization of this fru it in upgrading the health and economy of the coastal people of Indian Sundurbans.- Study on The Water Quality of The Shrimp Culture Ponds in Indian Sundarbans

Shrimp culture has high prospect in the socio-economic framework of Indian Sundarbans. However, the activity has considerable impact on the ambient environment in terms of water quality. The present programme has scanned the aquatic environment of 10 shrimp culture ponds at 10 different sampling stations of Indian Sundarbans with respect to surface water temperature, salinity, pH, transparency, nutrients, oil and grease and phytopigment levels along with the Condition Index of the cultured shrimps. The selected ponds are exposed to varying degree of anthropogenic pressure on the basis of their proximity to the highly urbanized and industrialized city of Kolkata and threats posed by brick kilns, tourism related pressure, non-scientific methods of shrimp culture etc. The health of the shrimp was found better at Bali and Chotomollakhali, where the adverse impact of city sewage is minimum and shrimp feed was scientifically formulated to maintain the water quality.References

Oceanography is a multidisciplinary subject in which the knowledge of geology, geophysics, chemis try, physics, meteorology, computer science and biology are used to understand the oceans. Physical oceanography critically investigates about the marine meteorology, the study of heat transfer, water cycles, ocean current and air sea interactions. Chemical oceanography studies the composition and history of seawater, its processes and interactions. Geological oceanography deals with various proc esses of ocean surface and ocean basins. Biological oceanography restricts itself in the domain of marine biota and the relationship between marine biodiversity and ocean environment. Ocean en gineering is the discipline of designing and planning equipments used for sea exploration.- Ichthyoplankton Community Spectrum in Coastal West Bengal : Threats and Conservation

The juvenile stage of finfish, commonly referred to as ichthyoplankton, constitutes an important component of the planktonic community in estuaries, seas and oceans. The pelagic and demersal fishery resources of coastal waters are intricately related to ichthyoplankton standing stock and community structure. Although many ichthyoplankton may not have direct edible food value from the point of view of human consumption, but their role in maintaining and stabilizing the brackish water food chain cannot be ignored. However this vital component of marine and estuarine biodiversity is presently under threat due to wild han/est of tiger prawn seeds from the coastal waters of West Bengal.
The seeds of tiger prawn have high demand in the coastal aquacultural farms and hence the brackish water systems are screened at regular intervals by thousands of seed catchers in search of the target species (PLj^ of Penaeus monodon). This practice is, however, associated with a huge quantum of finfish juvenile loss, which has great ecologic and economic valuation. The present paper attempts to highlight the quantum of finfish juvenile loss at three important zones of coastal West Bengal (selected on the basis of salinity profile: low, medium and high saline waters) since the last 10 years in terms of H. Although the sampling stations showed significant spatial variation in terms of physico-chemical variables, but the oscillation of ichthyoplankton community exhibited a common trend irrespective of space. The 10 years data bank reveals the ichthyoplankton diversity to be maximum in premonsoon and minimum in monsoon during the entire period of investigation, which may be related to the life cycle pattern of coastal and estuarine fishes in the study area.

Sharks are important members of marine and estuarine food wehs and liave unique status of tlieir own not only witti respect to tlieir morplioJogical features, but also of their commercial value. Beside, the edible value, this cartilaginous fish community has great demand in the pharmaceutical industry In India the present annual shark production is around 47,000 tonnes, obtained as by catch from a variety of gears. Despite such commercial importance, no serious attempts have so far been made at any targeted exploitation of these valuable resources. Information on the composition of the species of shark landing is very scarce apart from the gross catch statistics. There are reports of the decline of shark population due to overexploitation, illegal poaching, water quality alteration etc in the coastal zone of IVest Bengal The present paper is an attempt to highlight the threats operating on this important cartilaginous fish community, with a conclusive conservative approachKeywords

A monthly monitoring programme conducted at two different sampling stations in and around the mangrove ecosystem of deltaic Sundarbans, India during January, 2000 to December, 2001 showed maximum phytopigment concentrations during premonsoon and minimum during monsoon seasons. Physico-chemical variables like surface water temperature, salinity, pH, dissolved oxygen, extinction coefficient and nutrients were also analysed simultaneously during the monitoring period The concentrations of chlorophyll a, b andc exhibited significant positive correlations with surface water salinity and pH, but with nutrients like nitrate, phosphate and silicate, significant negative relationships were observed in both the sampling stations. The low phytopigment concentrations at station I may be related to severe anthropogenic stress around this zone.Keywords

The present study was carried out during February, 2022 to assess the role played by the major urban floral species in lowering the level of near-surface atmospheric carbon dioxide at five selected sampling stations in the megacity of Kolkata. Seventeen dominant tree species common in the five sampling sites were surveyed, out of which the highest and the lowest mean value of Above Ground Stem Biomass (AGSB) was exhibited by Eucalyptus globus and Alstonia scholaris respectively. The mean Above Ground Stem Carbon (AGSC) also exhibited similar trend with highest value of 2641.03 tha -1 by Eucalyptus globusand lowest value of 53.95 tha -1 by Alstonia scholaris. The soil pH at the sampling sites ranged between 4.9 to 6.2 and the Soil Organic Carbon (SOC) ranged from 0.52 to 1.29%. The near-surface atmospheric CO2 level showed the highest value of 418 ppm (at Moulali) and the lowest value of 403 ppm (at Park Circus). The study highlights the potential of urban trees to store carbon in the form of biomass. This can be an effective roadmap to underscore the rising trend of carbon dioxide in the near-surface atmosphere of the city.Keywords
