India has a long coastline of about 7,517 km. with 20% occupying the coastal area. Due to increase in population; people have been exploring the possibility of developmental opportunities in the coastal areas. Tsunami in 2004 was another unexpected natural catastrophe which badly affected many South Indian coastal states especially the state of Tamil Nadu. Coastal communities here are increasingly at risk from many chronic and episodic coastal hazards which threaten the health and stability of coastal ecosystems and communities. The degradation of the coastal environment from chronic human-induced actions threaten food security, livelihoods, the overall economic development and well being of coastal communities. Disasters big or small affecting the coastal communities are reminders that, coastal communities are not resilient to normally recurring hazards. This fact has raised the question of developing community resilience since the most effective approach to reducing the long-term impact of coastal hazards would be to enhance capacities of coastal communities through initiatives which are aimed at ensuring a sustainable recovery in the aftermath of a disaster as well as reducing people's vulnerability to these disasters. Eight elements of resilience i. e., Governance, Coastal Resource Management, Land Use and Structural Design, Society and Economy, Risk Knowledge, Warning and Evacuation, Emergency Response and Disaster Recovery have been identified which are considered essential to reduce risk from coastal hazards, accelerate recovery from disaster events, and adapt to changing conditions by the affected community. In this paper, all the eight resilience elements have been examined with respect to vulnerability and capacity assessment in selected Tsunami (2004) affected districts in the state of Tamil Nadu, India in order to identify the extent of resilience. © 2011 Springer Science+Business Media B.V.

In India, oysters, clams, mussels and a few gastropods are local delicacies along the coastal region. Of these total catch, few marine gastropods are not utilized by the people because of lack of awareness about the rich nutritive value of the seafood products. Keeping this in mind, an attempt was made to study the shelf life of the pickled product developed from gastropods such as Chicoreus ramosus and Hemifusus pugilinus for a period of 8 and 6 months at ambient temperature (30±2C). The acceptability of gastropod pickles decreased as free fatty acid, trimethylamine nitrogen, total volatile base nitrogen, total plate count and sensory scores increased (P<0.01 and P<0.05) at the end of storage period. It is ready-to-eat product, and it can be stored for a period of 8 and 6 months for C.ramosus and H.pugilinus pickle, respectively. PRACTICAL APPLICATIONS: Fish pickling has been one of the most popular traditional preservation methods in India. Fishes are mainly preserved by using tamarind, spices, salt and acetic acid as pickling agents. These seafood pickles are safe without any harmful bacteria and have a long shelf-life period for more than 6 months at ambient temperature. However, gastropods are not familiar seafood and are consumed only by certain section of fishing population in India. They are fished mainly for their beautiful shells and operculum. The shells are used as ornaments and also used in lime industry. The operculum is used in Indian traditional medicine. For better utilization of these underutilized marine gastropods, pickled products were developed from Chicoreus ramosus and Hemifusus pugilinus. This present study would reveal the quality of pickled products and concluded that it can be stored for a period of 8 and 6 months. © 2012 Wiley Periodicals, Inc.

Objective: The main aim of the study is to find the nutritional properties of Jamun pulp powder even after drying under different drying condition. Total phenol, anthocyanin, and flavonoids present in each dried samples vary with respect to temperature. These results will be a source for the further study in antioxidants and pharmaceutical formulations. Methods: Quantitative analyzes of significant phytochemicals were performed by standard methods. 1,1-diphenyl-2-picrylhydrazyl assay was done to find out the antioxidant activity. Results: Among all the different dryers, the maximum amount of total phenolic content measured by Folin–Ciocalteau method was 13.99 mg GA equivalents/g, total flavonoid contents as measured by aluminum chloride method was 104.8 mg quercetin equivalents (QE)/g, and anthocyanin content 7.56 mg/g was found in freeze-dried at −40°. The lowest was found in cross flow dryer with phenol content 7.6 mg GA equivalents/g, flavonoids 34.05104.8 mg QE/g, and anthocyanin 1.43 mg/g. The antioxidant property was high in freeze dried powder. Conclusion: Syzygium cumini is an underutilized fruit which is available plenty in India. It has an abundant amount of antioxidant and nutritional properties which can be a high potent in pharmaceutical. © 2016, Asian Journal of Pharmaceutical and Clinical Research. All rights reserved.

The mammal washed ashore at Vadrevu port, Guntur district, Andhra Pradesh, south east coast of India was identified as Indo pacific male finless porpoise Neophocaena phocaenoides from their Morphometric characters-Dorsal and ventral measurements of the animal. This species was found to be the first record from Andhra Pradesh coastline, south east coast of India. Exact number of extant Phocoenids around India is still debated and the lack of adequate field keys has resulted in misidentification of several species of marine mammals. As a part of this study, diagnosis of the animal has been briefly described and tabulated. Literatures known and reports till date about this cetacean particularly in the current work has been derived from incidental data like stranding records and fisheries bycatch informations to make it more reliable for future research and conservation requirements. © 2014, National Institute of Science Communication and Information Resources (NISCAIR).

Bacterial strains associated with the barnacle Balanus amphitrite, distributed along Tuticorin coast, were studied for antagonistic activity against 10 human pathogenic bacterial strains. In cross streaking antibacterial assay involving the strains as such, antagonistic activity was observed in 14.3% of the 28 isolated associated bacteria. Out of four strains which showed antagonistic activity, the strain B3 showed higher antagonistic activity against 90% of bacterial pathogens. The subsequent culture of four active strains and screening of supernatant diethyl ether, chloroform, ethyl acetate and butanol extracts showed wide spectrum activity in ethyl acetate extract of B3 strain. The partitioning and column fractionation of supernatant ethyl acetate extract of B3 strain indicated wide spectrum antibacterial activity indicating the non-polar nature of the active substance. The strain B3 produced exocelluar metabolites, which though may have an ecological role to play with in nature, may provide a vital lead to antibacterials to combat human bacterial pathogens. © IDOSI Publications, 2011.
