Evaluation of fatty acid profile with special reference to hypertension intake from marine edible fishes

The present study describes the changes in fatty acid profile in hypertension patients by up taking the marine edible fishes Elutherenema tetradactylum, Sphyraena obtusata and Siganus javus because these marine edible fishes are rich in ? –fatty acids.  In this study the total cholesterol, HDL and LDL were significantly decreased from 211.9 – 202.1 mg/dl, 177-159.6 mg/dl. The palmitic acid (C16:0) was found significantly higher in all of peoples compared with other SFAs. This study revealed that the most abundant in individual FAs 16:0,18:0,18:1 n9 and 20:2 n6 were present in blood in both before and after dietary intake. The minimal changes of SFAs levels were decreased averagely from 59.2 to 52.2%. In addition to above PUFAs also increased from 27.7-30.5%. The essential FAs like ALA (C18:3n3), EPA (C20:5n3) and DHA (C22:6n3) were accounting in the range of 2.64-2.92%, 3.67-3.94% and 3.65-4.38%. Omega – 6/3 ratio were recorded from 1.77-2.45%. This study proves the marine edible fishes reduce the hypertension of the patients. Keywords: Edible fishes, ? –fatty acids, SFAs, HDL and LD

Distribution of finfish resources along southeast coast of India in relation to certain environmental parameters

This paper embodies the distribution pattern of major finfish resources along the southeast coast of India as observed during the cruises operated by FORV Sagar Sampada. A total of 16 cruises (1985-90) operated along latitude 7° 15'- 15°00' N and longitude 75°50'- 82°3r E hauled a total catch 37.5 tonnes with a catch rate of 537 kg/hr. The catch was constituted mainly by threadfin breams (43%), perches (14%), barracudas (9.72%), carangids (8.56%) and elasmobranchs (4.81%). Seasonally higher catch rates were obtained during July- September period. Depth range of 60 - 80 m had denser population of finfish resources. Water temperature and salinity appeared to influence the distribution of major finfishes more than dissolved oxygen. Groups such as threadfin breams were found preferring cooler waters of Wadge Bank area, while barracudas appear to occupy warmer waters of Gulf of Mannar

Trends in secondary production in the inshore waters of the seas around India

CMFRI has been monitoring the microscopic organisms which belong to the categories of phyto and zooplanktons, being a reliable tool for the identification of areas prone to industrial and natural pollution and for understanding its extent and intensity, especially in the inshore areas selected centres along the Indian coasts.These studies assist in foretelling any alarming situations developed in the living environment that may affect the commercially important resources adversely. The pattern of the occurrence and abundance of zooplankton along the Indian coasts from Bombay on the west coast upto Madras on the east coast were described.The samples were collected from Bombay, Karwar, Calicut, Vizhinjam, Tuticorin, Mandapam and Madras. In conclusion,the rate of secondary production on the west as well as on the east coasts during the 1981-82 period was comparatively lesser than during the previous year

Major and minor fisheries harbours of India. 6. The fisheries harbour and fishery at Tuticorin

The Tuticorin Fisheries Harbour Is one of the old and important fishery ports of India located on the southern Tamil Nadu coast and on the western side of the Gulf of Mannar. Now owing to its commercial and economic importance from the marine fisheries point of view it is considered as one of the major fisheries harbours on the east coast of India. The harbour was constructed at a cost of Rs. 2.1 crore in 1968 in a total area of 17 acres, out of which the berthing area is 2.7 acres. This harbour has a berthing facility to accommodate 450 medium sized mechanised wooden trawlers. The total length of the jetty is 800 m and the depth in the area of berthing is 3m

Survey of Valinokkam Bay and adjoining area to assess its suitability for integrated sea farming — A report

The Valinokkam Bay and the adjoining area, east of the Bay surveyed, lie between Lat. 9°9' N and 9° 12' N and Long. 78°30'E and 78°42'E . The available information indicates that the bay and the adjoining grounds in the sea are highly productive and suitable for sea farming activities

A bibliography of parasites and diseases of marine and freshwater fishes of India

With the increasing demand for fish as human food, aquaculture both in freshwater and salt water is rapidly developing over the world. In the developing countries, fishes are being raised as food. In many countries fish farming is a very important economic activity. The most recent branch, mariculture, has shown advances in raising fishes in brackish, estuarine and bay waters, in which marine, anadromous and catadromous fishes have successfully been grown and maintained

Culture of fishes in cages and pens along the coastal waters of India

The results of culture attempts of milkfish, Chanos chanos, Mugil spp., prawn Penaeus indicus and crab Scylla serrata in enclosures of bamboo splits (thatti), fixed in shallow inshore waters at Tuticorin, are summarized

Effect of Temperature, Dissolved Oxygen Variation and Evaporation Rate in Marine Aquarium

Abstract: A marine aquarium was established at Annamalai University 30 km away from the coast with recycled seawater system. The problems faced during the operations were increase in water temperature, consumption of dissolved oxygen and evaporation of seawater. The rate of evaporation of water in entire aquarium was estimated about 128 liters/day. The temperature increase in the aquarium tank was observed as 0.1ºC due to the operation of canister filter, 0.1ºC due to pumps and 1.1ºC due to aquarium lightings. Further the position of aquarium lids leads to a raise in temperature of 0.5ºC. The consumption of dissolved oxygen by eight band butterfly fishes Chaetodon octofasciatus was taken as a case study and found to be 2.031x10 G4 ppm/g of biomass. The optimum stocking density for balanced dissolved oxygen condition was calculated as 0.919 kg of biomass / 1,000 liters of seawater with the aeration of 0.351 ppm/hr

Clostridium lundense sp. nov., a novel anaerobic lipolytic bacterium isolated from bovine rumen

A strictly anaerobic, mesophilic, endospore-forming, lipolytic bacterium, designated strain R1T, was isolated from bovine rumen fluid and characterized. Cells of this isolate were Gram-positive, non-motile rods that formed spherical terminal spores. The overall biochemical and physiological characteristics indicated that this strain should be placed in the genus Clostridium. The strain grew at temperatures between 25 and 47 °C (optimum, 37 °C), at pH between 5·0 and 8·5 (optimum pH 5·5–7·0) and in NaCl concentrations of 0–3 % (w/v). The isolate was not able to utilize glucose or other carbohydrates as carbon sources. The DNA G+C content was 31·2 mol%. Sequence analysis of the 16S rRNA gene of R1T revealed that it has the closest match (98 % similarity) with Clostridium tetanomorphum DSM 4474T. The highest levels of DNA–DNA relatedness of the isolate were 61·9 and 54·3 % with Clostridium pascui DSM 10365T and C. tetanomorphum DSM 4474T, respectively. Based on 16S rRNA gene sequence similarity, phylogenetic analysis, DNA G+C content, DNA–DNA hybridization data and distinct phenotypic characteristics, strain R1T (=DSM 17049T=CCUG 50446T) was classified in the genus Clostridium, as a member of a novel species, for which the name Clostridium lundense sp. nov. is proposed.Fil: Cirne, Dores G..
