Cephalopods are ecologically and economically important marine groups in the world. Biodiversity description is essential for sustainable utilization of natural resources and to characterize biological entities for conservation. DNA barcoding is an effective tool used for identification of organisms at species level and is been widely used for delineate several ambiguity species. In this study, partial sequence of mitochondrial cytochrome c oxidase 1 (CO1) gene with a mean size of 680 bp was amplified by universal primers. Totally 13 individuals of Cephalopods comprising of three species, were barcoded and genetic variation was analysed. The maximum A+T content (67.60%) was recorded in Cistopus indicus and minimum (63.70%) in Sepioteuthis lessoniana. The maximum K2P distance (0.268) was found between the genus Cistopus and Sepioteuthis whereas the minimum distance (0.188) was observed between Uroteuthis and Sepia. The neighbour joining tree revealed three distinct clades represents Loligonidae, Sepiidae and Octopodidae with high boot strap values. However, Sepioteuthis lessoniana is showing a bifurcated branch and it may due to the co-occurring of cryptic species and till date this species is treated as Sepioteuthis lessoniana complex.

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.

Appropriate day lighting design saves lighting power energy (LPE) and reduces LPE cost. This research investigates daylight contribution of in selected north campus lecture theaters in a South West Coast University of Nigeria. TES 1332A lux meter was used for lux level determination. The window area to wall area (AWD to AW) ratio was determined using reliable algorithms. In the three studied buildings, the daylight contribution varies from 12 lux to 3803 lux; AWD to AW varies from 14 % to 22 % to 37 %; 22 % AWD to AW is considered moderate while 37 % AWD to AW is considered more suitable in the studied buildings.
