Local people suspect that this act of poisoning the water is revenge against forest officials for the eviction drives. The mass killing created a panic among residents. Khasi Students Union, has alleged that the exploratory drilling for uranium in the hinterlands, on the upstream of the river, was the reason behind the incident.

Incidents of dead fish and snakes floating in Ranikor river was happening since and multiple probes carried out by the govt always ruled out that the fish and snakes were killed due to exploratory drilling for uranium. The deaths have become quite common since the first incident in A probe was ordered amid suspicion that the water in the Mondalghat area along a 2 km stretch of the river might had been poisoned.

Earlier, in andsimilar incidents had occurred in Karala, a rivulet flowing through Jalpaiguri town and merging at the Teesta. It was learnt that insecticides were put in the river water to catch fish.

Also, poison was mixed in the water of Teesta in Dec. Odisha Mass fish death in Bata river triggers panic Panic gripped locals of Balijhara after thousands of dead fish were found floating in Bata river in April The locals including fishermen alleged that some miscreants might have poisoned the river water to settle scores with the successful bidders who have taken up fish cultivation in Bata.

A similar incident had taken place in when thousands of dead fish were found in Bata River. A team of Odisha State PCB had collected water sample and dead fish for tests and found that lack of oxygen level in the water had caused mass death of fish.

As per a State PCB official, such instances have also occurred in the past. He further said that waste discharge in the river by nearby industries could be the reason for fish death. Fishermen of Getalsud Matsya Sahog Samiti Limited, a cooperative of local fishermen who are patronised by state fisheries department, who informed the state fisheries department of the incident, alleged one of the industries nearby had released untreated effluents in the dam.

The samiti had around fishermen as members. Directly and indirectly close to 5, people were dependent on fishing at Getalsud as their lone source of livelihood. Ashish Kumar, deputy director of state fisheries department, confirmed having received the information from fishermen. Member secretary of Jharkhand State PCB, Rajiv Lochan Bakshi said they would take strict action against erring companies if any was found guilty of polluting the water body. According to locals the depletion in water level and rise in pollution in form of solid and liquid was of the water body were main reasons behind the repeated fish kill incident.

While the pond was cleaned up and its embankment were concretised, sewage contamination seems to have resumed in it. VMC councillor Vijay Pawar said that he had spotted the contamination some time back and even informed the top brass of the civic body.

But no action was taken. Mamlanagar pond was amongst the first to be spruced up in the city. Environmentalists had, however, raised questions about the work on the pond stating that with stone masonry embankments it had become a tank and would not be a live water body.

It was after this that the VMC stopped the process of having concrete borders of ponds. Foul smell emanating from the dead fish affected the movement of people. The pond was tickly covered with water hyacinth. Sewage water from nearby localities was entering the pond. Some industries were also discharging their polluted water in it.

A similar incident had taken place few days back in Badodiya pond. As per locals the water body had never dried in last three decades. They tried to fill the water body with tube wells.

The phenomena has become an annual affair. In the month of June, local people used to offer flours and other grains to fish out of religious sentiments. This could lead to oxygen demand in the river killing the fish population. The locals said that the starfish could have perished due to the muddy water that was the result of heavy rains in the area.

Sea water turned muddy after a rainy spell in the state. Locals were also baffled with the sight of the dead starfish as such an event had not been seen in the last few years. The spot where the dead starfish washed was not very far away from the popular Miramar beach. Similar incidents have taken place in April and in June In reality, however, Kshipra remains parched where it enters Ujjain and the extent of its pollution is evident from the colour of river water at Ram Ghat.

Residents from the immediate vicinity said it is a common sight every year. According to Dr Vinay Deshmukh, Former principal scientist at Central Marine Fisheries Research Institute CMFRI during this ritual, cooked rice balls and wheat are immersed in water, which not only becomes food for bacteria but also increases their population. The bacteria consumes the dissolved oxygen thereby depleting it quickly resulting in mass death of fish and the only solution is to stop immersing the offerings in water.

It was only after they began circulating pictures on social media did authorities get wind of it. As per environmentalists such mass fish deaths had happened in Singanallur and Sulur lakes for past 7 years. They suspected water contamination with highly toxic sewage to be the reason.

Many more lying in riverbed. The site has become a graveyard for turtle too. Lab test hints pollution to be culprit but govt thinks otherwise. However the two incidents in the space of three years have left fishermen in the village worried about the impact on their livelihoods. As per local fishermen high influx of raw sewage from upstream residential localities, industries and hospitals have led to the incident.

Locals also allege that some of the industries in SIPOT at Irungattukottai, Pallipattu, Somangalam, Amarambedu and Chembarambakkam release untreated effluents into the neighbouring water streams during monsoon period, which eventually flow into the Adyar estuary. Locals allege that a few criminals have poisoned the river water to catch fish easily and in huge numbers.

Following outrage by local fishermen, the police have launched an inquiry into the issue. It was feared that contaminated water was responsible for the death of fish. Environmentalists opined that owing to the huge organic load, the dissolved oxygen level in water had depleted abysmally resulting in the death of fish which was said to be happening for the last 3 or 4 days.

They suspected seepage of effluent from Paduvarahalli area. The lake staff removed the dead fish. The authorities collected the samples of dead fish and have sent the same to a laboratory in Bengaluru and also collected water samples for testing. The place where sewage water was flowing into the lake was emanating foul smell. Karnataka State Co-operative Fisheries Federation KCFF has the right for fishing but due to lack of cooperation between the University of Mysore and the Federation, fishing has been stopped in the lake for the last few months.

As a result, the population and size of the fish started increasing. The University authorities claimed that since the Model Code of Conduct was in place for Karnataka state electionsthey could not call for fresh tenders. Jayaramaiah, Non-official Member, Karnataka Tank Conservation and Development Authority, waste water from cow sheds and houses of Paduvarahalli flowing through open drains collect at shallow places at the junction of Hunsur Road and north bund of the lake.

This polluted water was entering the Lake through drains located at north bund killing fish by reducing the oxygen level in the lake water. While residents of the locality pointed to sewage flow and poor maintenance of the water body by the Bruhat Bengaluru Mahanagara Palike BBMPthe civic agency attributed the fish deaths to abrupt fall in oxygen levels in the lake.

Residents said the lake, spread over acres, and received polluted water from surrounding areas over the last few months. Four bacterial isolates, which proved to have the potential to be used as probiotics, were used to study their genotypic characterization using analysis of 16S rRNA gene sequence, antagonistic ability and safety when applied on tilapia via immersion. Gram staining showed that all 4 probionts were Gram positive bacteria.

Three probionts were rod in shape and the fourth was cocci in shape and arranged in grape-like cluster. These 4 probionts were also identified using 16S rRNA gene sequencing and their identities were Paenibacillus barcinonensis strain D12, Paenibacillus sp.

All of the probionts were examined for their antagonistic ability against pathogenic bacteria Vibrio alginolyticus ATCCAeromonas salmonicida and Aeromonas hydrophila ATCC under in vitro conditions by using cross-streaking method.

On the other hand, A. The greatest inhibitory activity against Salmonella Typhimurium was shown by C. Most of the extracts inhibited the growth of E. Asian Journal of Biological Sciences 5 5: The aim of this study was to evaluate bacterial quality and pathogenic organism presence in the Nile water Blue, White and Main River Nile as sources of drinking water in Sudan. The bacterial genera were isolated and identified using microbiological and biochemical method of evaluation. The most predominant aerobic microflora genera and species found in the Nile waters were Bacillus, Aerococcus, Micrococcus, Pseudomonas, Staphylococcus, Actinomycetes, Aeromonas and Streptococcus.

Only two genera were identified to their species, Bacillus B. Penibacillus and Streptococcus S. The most frequent coliforms isolated were Escherichia coli, Enterobacter aerogenes, Enterobacter cloacae, Enterobacter agglomerans, Klebsiella oxytoca, Klebsiella planticola, Serratia spp. The results of bacterial genera isolated in this study indicate that, the Nile water was potentially contaminated with the pathogenic bacteria and therefore, presence of Escherichia coli could be public health risk.

Asian Journal of Biological Sciences 6 2: This study was conducted to assess microbiological quality of a local fresh water fish of Bangladesh named mola, Amblypharyngodon mola. The effects of freezing temperature, irradiation and their combination treatments on the associated microorganisms during storage of the fish were also evaluated.

For this purpose, fish samples were collected from a local market and irradiated with different doses 2. Seventy six bacterial strains were isolated and identified from these samples which include Staphylococcus aureus, Micrococcus varians, Aeromonas hydrophila, Pseudomonas aeruginosa, Escherichia coli, Klebsiella ozaenae, Bacillus subtilis, Bacillus megaterium, Klebsiella edwardsii and Micrococcus radiodurans.

When treated with gamma radiation dose, the total coliform, faecal coliform, Aeromonas sp. During frozen storage, microbial counts were gradually decreased with time. However, the combination of these two treatments was found more effective than any of the single treatment for elimination of the associated microorganisms. The moisture contents of mola fish were not changed significantly at different stage of storage periods and also at different radiation doses.

On the other hand, losses of total protein contents were also very low with increasing storage time and radiation dose. The findings indicated that, the combination treatment can be applied for long time preservation of mola fish in Bangladesh without any significant loss of moisture and protein values. Asian Journal of Biotechnology 3 5: Dual culture of some bacterial isolates obtained from animal manure compost extracts with F.

The transplantation of tomato seedlings cv. Riogrande in peat, previously treated by bacterial suspensions and inoculated with a conidial suspension of the pathogen spores mL-1significantly reduced the Fusarium Crown and Root Rot severity compared to the untreated control. The most effective isolates were identified by means of the API system, as Chryseomonas luteola, Serratia liquifaciens and Aeromonas hydrophila.

Asian Journal of Plant Pathology 2 1: The antibacterial screening of hexane, chloroform and alcohol extracts of leaves of Finlaysonia obovata was carried out against fresh water fish pathogenic bacteria viz.

The hexane and chloroform extracts were found active against four and five pathogens, respectively. Chromatographic purification of active extracts improved the activity profiles. The GCMS analysis of extracts analysis revealed the presence of triterpenes and hydrocarbons as major constituents. The fatty acids composition of the leaf is also studied by FAME analysis.

It contains palmitic acid as a major constituent Two important poly unsaturated fatty acids i. Asian Journal of Plant Sciences 6 1: Three xylanase-producing Aeromonas strains St1, So1 and So2 were isolated from stagnant water from Rajshahi University campus.

The strains were isolated on xylan agar media and screened by -xylanolysis method. This strains showed drug resistance to cotrimoxazole, ampicilline and amoxycilline when tested by disc diffusion method on nutrient agar or xylan agar plate respectively. This strains also showed sensitive to erythromycin, tetracycline and doxycyclin. The minimum inhibitory concentration MIC of erythromycin, tetracycline and doxycyclin was determined by serial dilution technique against three test bacterial strains.

Plasmid DNA was isolated the multi-drug resistant strain St1. These drug resistant plasmids were transformed into sensitive E. The transformed LE became resistant to cotrimoxazole, ampicilline and amoxycilline and the respective plasmid DNA was detected in the plasmid DNA isolated from transformed E. The antibiotic resistant in Aeromonas was plasmid born. Two Thermophilic bacteria which exhibit antimicrobial activity were isolated from hot spring Jordan Valley.

Those Gram-negative rods shaped were found to be Yersinia sp. Extracts from aqueous phases of the tow strains were tested for antimicrobial activity by agar well diffusion method against 6 microorganisms Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Enterobacter sp.

The highest antimicrobial activity was recorded by Yersinia sp. Extracts from the two thermophilic strains showed relatively high antibacterial activity against Staphylococcus aureus. The selective production of GlcNAc was observed during continuous hydrolysis of chitin and at the same time period, the production of GlcNAc oligomers was negligible below 0.

These results suggest that the multi-chitinolytic enzyme complex produced by Aeromonas sp. PTCC could be useful for bioconversion of chitin waste into N-acetyl-D-glucosamine for industrial applications.

In study to obtain a safe Bacillus probiotic for Nile tilapia Oreochromis niloticus cultivation, hemolytic activity on blood agar medium was used in isolation of Bacillus probiotic species from gastro-intestinal tract of Nile tilapia.

One hundred and three isolates of Bacillus sp. Among these isolates, however, there was only 1 isolate, named as Bacillus UBRU4 which showed the inhibitory effect on Aeromonas hydrophila growth. The results of physiological and biochemical test and molecular identification This was possibly the first report of isolation of Bacillus brevis in aquaculture.

The maximum cell numbers of Bacillus UBRU4 in modified broth culture medium was obtained when using the medium contained 30 g L-1 of Nile tilapia commercial feed and 20 g L-1 of molasses.

The specific activity of the bioactive compound was increased from 1, to 5, AU mg These results suggested that the Bacillus UBRU4, thus, could possibly be used as high potential probiotic in Nile tilapia feed. Fifty strains of different microorganisms with ability to degrade chitin were isolated during a screening program.

One of the most potent isolates strain JK1 was identified as Aeromonas sp. Identification was carried out using morphological and biochemical properties along with 16S rRNA partial sequence analysis. This strain was able to produce high levels of extracellular chitinase in media containing chitin as sole carbon source.

The effects of medium composition and physical parameters on chitinase production by this organism were studied. The optimized medium was found to contain colloidal chitin 0. The highest enzyme production by Aeromonas sp. With respect to high amount of chitinase production by this strain in a simple medium and the relatively short time, this strain could be a suitable candidate for production of chitinase on an industrial scale and merits further investigation into its structure and characteristics.

The bacterial isolate SR2 was resistant to most of the antibiotics tested, but sensitive to levofloxacin.
