    Biochemical composition and the elemental chemical constituents of the planktonic sergestid shrimp, Lucifer hanseni Nobili were estimated during October 1991 - May 1992 from a selected station off \^pin island in the Cochin estuary. Protein formed the m^or fraction of the organic constituents. Seasonal variation was observed in the protein content. Protein and lipid fractions were inversely proportional. Neither lipid nor carbohydrate appeared to be significant energy sources. Lipid was the most variable component. An inverse relation was evident between the moisture content of the shrimp and its lipid level. Carbohydrate content of the organism was found complementary to its lipid content. Decrease in carbohydrate content was recorded during periods of low salinity. Values of chitin and ash were less variable. There was marked seasonal variation in the moisture content. Calorific content of L. hanseni estimated as 4.527 k cal/g ash free weight was found comparable with that of other cadidate species selected as live feed. The average values of carbon, nitrogen and hydrogen were 39.84%, 8.73% and 6.09% respectively of dry weight

    The distribution and abundance of decapod shrimps of the family Luciferidae De Haan, 1849 under the super family Sergestoidea Dana, 1852 in the Exclusive Economic Zone of India were studied based on 918 zooplankton samples collected during 37 cruises of FORV Sugar Sampada. All the seven species recorded elsewhere in the world namely, L. @pus H. Milne Edwards, L. hnnseni Nobili, L. penicillifer Hansen, L. faxoni Borradaile, L. chacei Bowman, L, intermedius Hansen and L. orientalis Hansen have been found to occur in the Indian EEZ of which the last three are new records. L. penicillifer is the predominant species in the eastern Arabian Sea and the Bay of Bengal and L. typus in the island ecosystems of Lakshadweep and Andaman- Nicobar. The neretic region of the Indian EEZ up to 50 m depth supports 51% of these shrimps, the mid-shelf between 50 and lOOm harbours 29%, whereas 12% occur in the outer shelf (100 and 200m) and 8% in the deep zone (>200 m). The presence of L.penicillifer in the eastern Arabian Sea and L.hanseni in the Lakshadweep waters is reported for the first time. Matrix of correlation revealed the highest co-occurrence of these shrimps in the Andaman-Nicobar waters wherein six of the Lucifer species co-exist. Diagnostic characters used in species identification are given and illustrated

    The Central Marine Fisheries Research Institute, Cochin was recognized as a 'Designated National Repository' by the Government of India, in December 2007 in consultation with the National Biodiversity Authority under the Biological Diversity Act, 2002. A Designated National Repository (DNR) is an Institution authorised to keep in safe custody specimens of different categories of biological material. The Museum offers a glimpse of the bioresources of the Indian seas. Currently the museum houses six holotype specimens, 878 finfish species, 136 crustaceans, 217 molluscs, 44 echinoderms, 162 corals, 12 sponges, 20 ascidians, 82 seaweeds and 8 seagrasses besides a dolphin and three Antarctic birds. The Museum is open to scientists, teachers, students and the general public. The fact that students form more than 85% of the visitors highlights the role played by the Museum in education. A catalogue of the specimens available in the Museum has been prepared as it is expected to be of immense use to those engaged in marine biodiversity studies. I sincerely thank Dr. G. Syda Rao, Director, CMFRI whose guidance and encouragement made this a reality

    The pteropod and heteropod molluscs formed an Important constituent in the zooplankton of the EEZ of India and the adjacent areas. Between them the pteropods dominated numerically over the heteropads in all situations. The average density of pteropods in the area investigated was 734 (expressed as number per 1000 m3 of water) and heteropoda was33

    A systematic review of cost-effectiveness analyses of complex wound interventions reveals optimal treatments for specific wound types.

    BackgroundComplex wounds present a substantial economic burden on healthcare systems, costing billions of dollars annually in North America alone. The prevalence of complex wounds is a significant patient and societal healthcare concern and cost-effective wound care management remains unclear. This article summarizes the cost-effectiveness of interventions for complex wound care through a systematic review of the evidence base.MethodsWe searched multiple databases (MEDLINE, EMBASE, Cochrane Library) for cost-effectiveness studies that examined adults treated for complex wounds. Two reviewers independently screened the literature, abstracted data from full-text articles, and assessed methodological quality using the Drummond 10-item methodological quality tool. Incremental cost-effectiveness ratios were reported, or, if not reported, calculated and converted to United States Dollars for the year 2013.ResultsOverall, 59 cost-effectiveness analyses were included; 71% (42 out of 59) of the included studies scored 8 or more points on the Drummond 10-item checklist tool. Based on these, 22 interventions were found to be more effective and less costly (i.e., dominant) compared to the study comparators: 9 for diabetic ulcers, 8 for venous ulcers, 3 for pressure ulcers, 1 for mixed venous and venous/arterial ulcers, and 1 for mixed complex wound types.ConclusionsOur results can be used by decision-makers in maximizing the deployment of clinically effective and resource efficient wound care interventions. Our analysis also highlights specific treatments that are not cost-effective, thereby indicating areas of resource savings. Please see related article: http://dx.doi.org/10.1186/s12916-015-0288-5

    Quantitative abundance of amphipods around Andaman-Nicobar Islands

    The present study deals with the quantitative distribution and abundance of amphipods of the Andaman Sea in time and space, based on the zooplankton samples collected during the cruises 46- 73 of FORV Sagar Sampada during 1988-1990. Mean number of amphipods (no/1000 m ) reached the maximum of 1763 in January and the minimum of 315 in July. The seasonal density was maximum during the northeast monsoon and minimum for the southwest monsoon and their mean numbers were estimated as 812 and 463/1000 m respectively. In general, they were abundant in the region where the station depths ranged between 50 and 100 m with the mean estimated as 800/1000 m of water. Analysis of day and night samples did not show any remarkable variation. The distribution and abundance of amphipods in relation to time and space are discussed in the paper

    Higher concentrations of zooplankton standing stock and population occurred in the region off Chilka lake and Paradip (19┬░ 10'N-19┬░ 55'N and 85┬░09'E-86┬░ 50'E) during January and off Visakhapatnam (17┬░30'N- 18┬░28'N and 83┬░14'E- 84┬░29*E) during November and April. The most productive period along the northwestern part of the Bay of Bengal was the northeast monsoon season (October-January) followed by the premonsoon season (February-May). High abundance of copepods, chaetognaths, siphonophores, cladocerans, fish larvae, planktonic molluscs, amphipods, foraminifers and larval polychaetes constituted the northeast monsoon maximum. Very low biomass values were recorded during the southwest monsoon season (June-September). The neretic zone up to 50 m depth was rich in zooplankton population during northeast monsoon and further to a lesser extent up to 100 m during the premonsoon season. However, a steady decline was evident with increasing depth zones. The less saline northern part exhibited remarkable differences in the abundance of the population and standing stock in such a way that 63% of the total was confined to the northern region. Fish eggs were predominant during February-May and larvae in July and January-February. The peak period of the zooplankton population coincided with the maximum landings of the pelagic and demersal fishery resources of the northwestern coast of the Bay of Bengal

    livelihood for millions of people around the world. The complimentarity and interdependence among the women and men is essential for the sustenance of the sector. In fishery sector women play significant role in maintaining household and community needs. Yet their roles remain largely unarticulated and unacknowledged. It is being recognized that fisheries as a sector will achieve full development if women involved in the sector have equal opportunities with men. The empowerment of women is very important for the socioтАРeconomic development of the fisherfolk. It is the need of the day to empower the women тАР socially, economically, politically, an
