The levels of macro and micro nutrients in the edible portions of some commercially important fin fishes were determined using the methods recommended by Association of Official Analytical Chemists (AOAC). All the fish species investigated were fairly high in macronutrient protein (18 - 21%), while the lipid content was less than 3%. All the fish were observed to contain no carbohydrate and the moisture and ash content varied within a narrow range. The levels of minerals varied from one fish species to the other. The most abundant micro nutrient was potassium followed by phosphorus, sodium, magnesium, calcium, zinc, iron, copper and manganese respectively. The micro and macro nutrient of all the samples did not exceed the recommended safety limits of sea foods specified by the World Health Organization (WHO, 2013). Considering the result of the present study, it can be concluded that all the species are rich in food value. © All Rights Reserved.

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.

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.

A total of 40 extract types of varying polarities from commonly occurring seagrasses were tested for their antibacterial efficiency against 14 clinically isolated human pathogens using agar well diffusion technique. The extracts from acetone of Cymodocea serrulata expressed moderate broad span of activity against a range of gram-positive and gram-negative isolates that were at least resistant to five of the commercially available antibiotics at a minimal concentration of 10μg. The active extracts of C. serrulata that showed maximal inhibitions were purified using column chromatography that afforded six compounds (a-f). Compound f elicited pronounced inhibitions against Escherichia coli with minimal inhibitory concentration values of 1-3μg concentration using micro-dilution method. The active compound was identified as phenyl thioketone using various spectral analyses. This is the first investigation that reveals thioketone functionality from this seagrass species possessing antibacterial actions. This study indicates that there are thiocarbonyl groups from marine floral sources too, which could be possibly used for therapeutic purposes. Copyright © 2015 John Wiley & Sons, Ltd.

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.

Present study consists the details related to the nature of coral disease in nine locations from Vethalai to Rameswaram north in the Palk Bay. Among the overall corals 21% were affected by disease. Six disease types were documented. Black Band Disease (BBD) is high with 9.8% followed by white band (5.5%), white spot (2.2%), pink spot (1.9%), white plague (1.1%) and yellow band (0.6%). Eight coral genera were found to be affected wherein Acropora and Porites showed severe damage and the high prevalence of diseases. The coral genus, Porites was found to be affected by four different types of diseases. BBD affected colonies were tagged and photographed at regular intervals to quantify the progression rate in two coral genera, Acropora and Platygyra and the disease progression rate was 3 cm per month. White band disease was widespread and was found to affect exclusively Acropora sp. Corals like Symphylia sp. and Cyphastrea sp. in the Palk Bay were comparatively not affected by diseases. Total heterotrophic bacteria and pathogenic microbial forms in the reef environment were also examined in the present study.

Objective: To screen the antibacterial drugs from different solvent extracts of tissue of marine gastropod Harpa davidis against clinically isolated human pathogenic bacteria and fish pathogens and to evaluate the biochemical composition and functional groups of the sample. Methods: Crude extract of gastropod was tested for inhibition of bacterial growth. Antibacterial assay was performed by disc diffusion method. Biochemical composition of the tissue extract was analyzed using standard procedures. Moreover, Fourier transform infrared spectroscopy (FTIR) spectrophotometry analysis was also studied. Results: The antimicrobial activity was measured based on the zone of inhibition around the disc impregnated with gastropod extract. The maximum zone of inhibition (10 mm) was observed against human pathogen Bacillus cereus in the crude methanol extract of H. davidis and the minimum zone of inhibition (2 mm) was noticed against Shigella dysentriae in the crude ethanol extract of H. davidis. In the case of fish pathogens, a maximum zone of (5 mm) was observed by methanol extract against Vibrio anguillarum and a minimum zone of 2 mm was observed by ethanol extract against V. alginolyticus. The proximate composition, such as protein, carbohydrate, and lipid contents of H. davidis tissue, was estimated. The results of this study revealed that the protein composition was high 38.42% followed by carbohydrate 9.61% and lipid 3.14%. FTIR spectrum of the sample H. davidis showed that 6 major peaks were shown at 3560.35, 2925.81, 2854.45, 1554.52, 1413.72, and 667.32/cm showing the presence of carboxyl, alkanes, aromatic, and alkyl functional groups. Conclusion: The present study indicated that the marine mollusc collected from the Kanyakumari coast possessed several bioactive compounds of therapeutic interest. Further studies are going onto isolate specific compounds and to study the biological activities present in them. © 2016, Innovare Academics Sciences Pvt. Ltd. All rights reserved.

Pattern of reproduction was studied in Acropora species along Tuticorin coast in the Gulf of Mannar from 2006-2008. Extensive surveys were conducted to monitor reproductive maturity and the timing of spawning. Gametes were observed from January with colonies releasing gametes by the end of March. Acropora cytherea showed immature colonies in January (48-79%) and February (56-76%) and mature colonies in March (36-86%). Likewise, the other species of Acropora examined showed 50-75% of immature colonies in January and an increase of 10-20% of immature colonies in February, and matured in March. The average percentage of mature colonies in March was as follows, A. formosa 47-76%, A. valenciennesi 50-81%, A. intermedia 50-81%, A. nobilis 25-82%, A. micropthalma 56-83%, A. hemprichi 39-83%, A. hyacinthus 33-100%, A. corymbosa 59-65%. Spawning was observed in A. cytherea on 24 March 2006, 10 days after full moon; 28 March in 2007, 5 days prior to full moon; and 8 March 2008, 1 day after new moon. Approximately 30,000 egg and sperm bundles were observed in 1 litre of water and each bundle had 20-25 eggs in A. cytherea. Environmental parameters, especially rise in temperature at the end of March was believed to play lead role in coral spawning.
