Abstract Background: Polychaetes are an important component of the estuarine and mangrove ecosystem especially in fisheries perspective. The polychaete fauna of the Manakkudy estuary barmouth and mangrove was examined for species composition and taxonomic classification. A total of 27 species belonging to 16 genera under 12 families were collected. Results: Of these 27 species, 16 are new records to Manakudy estuary. Out of which, those coming under the group Errantia were dominant (9 species) when compared to Sedentaria group (7 species). Among the 12 families identified, the species diversity of Nereidae and Capitellidae were found to be high. Conclusions: Salinity and nature of substrata, two main factors which govern the distribution of polychaetes, are also given along with species description.

The Mean

Mangrove ecosystem services are multi-dimensional (ecological, socio-cultural and economic), and their valuation is complex as not all of these dimensions are quantifiable in terms of monetary value. The main goal of this study was to determine the perception of local residents on the economic values of the mangrove ecosystem along the south west coast of Mauritius (Savanne and Black River Districts). A survey questionnaire (Savanne district, N=142; Black River district, N=126) was designed electronically in English and Mauritian Creole language using dichotomous, multiple choices and closed ended questions. The mean value for the awareness score was 52.3 and the standard deviation was 4.8 for the district of Savanne as compared to Black River district, where the mean value was 53.8 and the standard deviation was 9.0. The mangrove products harvested by locals from the surveyed sites were fish, crabs and oysters. The respondents were less willing to contribute to mangrove conservation activities both in terms of money (Savanne district, 4.2 %; Black River district, 3.9 %), and time (Savanne district, 7 %; Black River district, 4 %). Hence, campaigns and education programmes are critical to raise the awareness and concern of local residents to achieve Sustainable Development Goal (SDG) 14 in Small Island Developing States (SIDS) like Mauritius.

Silver bellies, Leiognathus splendens were studied for their spatial (south-west and south-east coasts of India), annual (2008–2011) and seasonal (pre-monsoon, monsoon and post-monsoon) variations of protein, amino acids, vitamins and minerals. The monthly mean Sea Viewing Wide Field-of-view Sensor data for the period from January 2008 to December 2011 were taken into account to indicate the distribution of the photosynthetic pigment chlorophyll-a to test the hypothesis that surface productivity might be related to nutritional biochemistry of this species. The four year average total protein content and chlorophyll-a showed good correlation during monsoon on the south-west coast and monsoon/post-monsoon on the south-east coast, suggesting that the protein content is prejudiced by the chlorophyll-a concentration. Amino acid scores observed monsoon maxima along the south-west and south-east coasts. Significant seasonal variations in vitamin content were observed at the study locations with high content of vitamins D3, E, K1 and C on the south-west coast. Na content was maximal during pre-monsoon on the south-west coast, while post-monsoon maxima of Ca and K content were observed. The Fe, Mn and Zn were abundant in the samples collected from the south-west coast. The concentration of Se exhibited maximum values post-monsoon along the south-west and south-east coasts. The present study demonstrated L. splendens as a valuable source of the protein, amino acids, minerals and vitamins, showing that this low-value species is a good source of well balanced proteins with high biological value to be qualified as a preferred healthy food for human consumption.

The muscle lipid, fatty acids and total cholesterol profiles of the spiny cheek grouper, Epinephelus diacanthus, collected from south-west (Arabian Sea) and south-east coasts (Bay of Bengal) of India were evaluated over four years (2008–2011) with regard to three seasons (pre-monsoon, monsoon and post-monsoon). Fatty acids were correlated with chlorophyll-a concentration and sea surface temperature. Lipid content, total polyunsaturated, eicosapentaenoic and docosahexaenoic fatty acids of the samples from the south-west coast showed positive correlation with chlorophyll-a concentration during the monsoon (r2 = 0.93, 0.97, 0.97 and 0.99, respectively). Higher hypocholesterolaemic/hypercholesterolaemic ratio (>1.0) and low atherogenic (<1.2), thrombogenicity (≤0.6) indices make the groupers collected from the coast of the Arabian Sea a valued candidate species for human nutrition. High levels of n-3 fatty acids (>19% during post-monsoon), important in the human diet for their platelet anti-aggregating and blood pressure-reducing properties, for groupers collected from the south-west coast, with higher n-3/n-6 fatty acid ratio (>5.1) proved this species from the coast of the Arabian Sea to be a desirable item in the human diet.
