Total viable counts (TVC), total coliforms (TC), faecal coliforms (FC), faecal streptococci (FS), presumptive <i>E. coli</i>, <i>Shigella, Salmonella,</i> <i>Proteus/Klebsiella, total Vibrio, Vibrio cholera, V. parahaemolyticus</i> and <i>Pseudomonas aeruginosa</i> as well as physico-chemical parameters are determined. Bacterial population was higher in Mahanadi, Paradip and Puri transects compared to other transects. Higher microbial population was recorded in stations close to the shore than the offshore (5 km and 10 km) stations. FC showed positive significant correlation with presumptive <i>E. coli, Shigella, Salmonella</i> and<i> Proteus/Klebsiella, Total Vibrio, V. cholera, V. parahaemolyticus </i>and<i> </i><i style="">P. aeruginosa</i>. TC showed the positive significant correlation with presumptive <i>E. coli</i>, total<i> Vibrio, V. cholera </i>and <i style="">P. aeruginosa</i>. FS showed the positive significant correlation with <i>Salmonella</i>, <i>total Vibrio, V. cholera</i> and<i> V. parahaemolyticus</i> and <i>Shigella</i>. Correlation analysis revealed positive relationships between faecal indicators and pathogenic microorganisms. Bacterial population showed positive relationship with BOD and negative relationship with salinity indicating dominant influence human activities. <b style=""></b> <br/> <br/>Page(s): 474-480 http://nopr.niscair.res.in/handle/123456789/7087 Title: Effect of salinity and dissolved nutrients on the occurrence of some seaweeds in Manakkudy estuary <br/> <br/>Authors: Jansi, M.; Ramadhas, V. <br/> <br/>Abstract: Manakkudy estuary, located on the South-West coast of India has production of seaweeds to an amount of 15.59 kg/m^2/yr. Four different types of seaweeds viz., <i style="">Chaetomorpha aerea, Enteromorpha compressa, Gracilaria verrucosa</i> and<i style=""> Hypnea musciformis</i> were observed in this estuary. Highest production of biomass (<i style="">C. aerea =</i> 842.33± 32.21 g/m²; <i style="">E. compressa = </i>619±16.09 g/m²; <i style="">G. verrucosa = </i>563.33±13.32 g/m² and <i style="">H. musciformis = </i>225.67±10.79 g/m²) of seaweeds could be recorded in May. During November i.e., a period of peak monsoon rain it is not present. Sea weeds were observed to occur in the euryhaline salinity range of 11.15 ± 0.48 to 27.18±0.88 ppt and the temperature ranging between 23.57°±1.00 and 31.70 ± 0.82°C. The quantity of seaweed is more when levels of nutrients were moderately high. <br/> <br/>Page(s): 470-473 http://nopr.niscair.res.in/handle/123456789/7086 Title: On use of post-stratification for estimating the marine fish landings <br/> <br/>Authors: Mini K G; Kumaran M; Jayasankar J <br/> <br/>Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="country-region"> The sampling design adopted by Central Marine Fisheries Research Institute for estimation of marine fish landings in India is a stratified two stage sampling design with stratification being done over space and time. Present study conists a modified design which uses post-stratified estimator to estimate the fish landings in a month in a zone along with its variance. The modified design improved the precision of the estimator as compared to the existing estimator. An empirical study is also carried out to demonstrate the performance of the modified design. </smarttagtype></smarttagtype> <br/> <br/>Page(s): 464-469 http://nopr.niscair.res.in/handle/123456789/7085 Title: Lipid profiles of Threadfin bream (<i style="">Nemipterus japonicus</i>) organs <br/> <br/>Authors: Nazeer, R A; Kumar, N S Sampath; Naqash, Shabeena Yousuf; Radhika, R; Kishore, Rahul; Bhatt, Sivani R <br/> <br/>Abstract: Present study of the lipid content in different organs of marine fish Threadfin bream (<i style="">Nemipterus japonicus</i>) indicates that a major amount of lipids are accumulated in liver (6.22%) when compared with remaining organs like muscle (2.7%) and skin (1.0%). Cholesterol studies reveal that muscle (36.2%) is having more quantities than liver (32.4%) and skin (24%). Fatty acid composition reveals that the lipids of each organ of threadfin bream are enriched in the unsaturated fatty acids and all the organs were found to be rich in linoleic (C_{18: 2}), oleic (C _18:1) and palmitic (C_{16: 0}). The present study further elucidates that a considerable amount of two physiologically important n-3 PUFAs, i.e. EPA and DHA were found more in skin (1.6% and 0.5%) and liver (1.6% and 0.6%) than in muscle (1.4% and 0.4%). <br/> <br/>Page(s): 461-463
