Antibacterial activity of a marine bacterium against pathogenic and environmental isolates of vibrio species

The marine environment covers three quarters of the surface of the planet is estimated to be home to more than 80% of life and yet it remains largely unexplored. The rich diversity of marine flora and fauna and its adaptation to the harsh marine environment coupled with new developments in biotechnology, has opened up a new exciting vista for extraction of bioactive products of use in medicine. In this study inhibitory activity of a marine bacterium isolated from gut of ribbonfish was studied against pathogenic and environmental isolates of Vibrio species. This strain was identified as Pseudomonas stutzeri and it was found active against V. harveyi (luminescent bacteria), V. cholerae, V. alginolyticus, V. damseal, V. fluvialis. The antibacterial substance produced by Pseudomonas stutzeri was soluble in organic solvent and closely bound to external surface of bacterial cells. Reduction of the absorbance of the V. cholera cell suspension was observed when log phase cells of V. cholerae were treated with MIC and 4xMIC concentration of crude extract of Pseudomonas stutzeri.

Mass culture of marine diatom Skeletonema costatum (Greville) Cleve collected from the Bay of Bengal

The growth of Skeletonema costatum in two artificial nutrient media was studied using various culture vessels. Skeletonema costatum was collected from the Cox's Bazar coast around the Bay of Bengal. Different growths stages i.e. lag phase, exponential phase, prestationary phase, stationary and death phase were observed during the culture period. The number of cells increased during the active division period and decreased after the beginning of the prestationary phase. The average densities of S. costatum in primary and secondary cultures were 0.55 x 10 super(6) cells mlˉ¹ and 0.93x10 super(6) cells mlˉ¹, respectively. In mass culture of S. costatum two, types of media were used. Highest cells densities of S. costatum cement tank culture were recorded 1.23x10 super(6) cell mlˉ¹ and 0.78x10 super(6) cells mlˉ¹ in their respective f/4 medium and commercial fertilizer medium. In the cement tanks culture fertilizer medium was found to be the best medium for mass culture of S. costatum in respect of production efficiency and culture stability.

Comparison the nutritional value of cultured Penaeus vanname with marine shrimps Penaeus merguiensis and Penaeus semisulcatus

The purpose for which this study was intended wasto compare nutritive value among the farmed Vannamei, sea Green Tiger and Banana shrimps native to the PersianGulf. To provide the samples of farmed shrimps at the end of the farming season (Oct. 23rd through Nov. 22nd of 2011), we chosen one farm of the Holleh Shrimp Farming, from which 100 shrimps were randomly selected. From among these 100 shrimps, 3 to 5 ones were taken to conduct an analysis upon. Further, to obtain the Banana and Green Tiger shrimps sampling was done at the fishing season (July 23rd through Aug. 22rd of 2011) at Halileh Fishing Wharf located in Bushehr Fishing Harbor and also Bandar Abbas Wharf. The samples obtained were immediately kept in the ice powder. After some biometric tasks done upon them, they were at the shortest possible time transferred to a laboratory where they went through various experiments to determine their content of raw protein, fat, ash, moisture, various fatty acids and their types, cholesterol, vitamins A and E, and such mineral elements as iron and calcium. All the experimentswere carried out three times to establish confidence in the results to be obtained. Findings of the comparison showed the content of raw protein, fat, moisture, and ash of, respectively, 23.233%, 600%, 73.077% and 2.500% for the Vannamei samples, of 22.717%, 427%, 74.133% and 1.826% for our Banana shrimps and of 17.377%, 430%, 79.866% and 1.313% for the Green Tiger samples. A total of 24 fatty acids for the Vannamei shrimps and 27 for the Banana and Green Tiger were detected. SFA of the Banana shrimps was 368.45 mg/100g (51.76%), while those of the Vannamei and Green Tiger samples were observed, respectively, 363.54 mg/100g (37.26%) and 296.06 mg/100g (49.12%).A similar measurement for MUFA content of the three types of our samples revealed 243.85mg/100g (24.9%) for the Vannamei, 203.177 mg/100g (33.76%) for the Green Tiger and 179.033 mg/100g (25.14%) for the Banana shrimps. The content of PUFA unsaturated fatty acids in the Vannamei, 131 Green Tiger and Banana samples were, respectively, 370.660 mg/100g (37.84%), 101.573 mg/100g (16.9%) and 163.733 mg/100g (23.1%). Further, the comparison found a omega-3-fatty-acids total of 151.747 mg/100g(15.51%) for the Vannamei, 57.123 mg/100g (9.54%) for the Green Tiger and 130.460 mg/100g (18.46%) for the Banana species under study.

Indian squid, Uroteuthis duvauceli, is an important commercial marine fauna in the coastal waters of Oman Sea

About 3600 specimens were collected by bottom trawl at 15 sampling stations. 24 biometric characters were measured for each specimens at the laboratory.. Microscopic cross – sections of statolith were used for age determination. Sex determination and fecundity were determined. Population dynamics parameters as well as stock as stock assessment including cohort analysis were estimated using FISAT software. The findings showed that Dorsal Mantle Length (DML) and Body weight (BW) of the Indian squid were 133.9 ± 0.78 mm and 99.61 ± 0.95 g respectively. Strong correlation was found between these 2 variables (R2 = 0.90). The maximum age was 5 years. Relationship between DML and age was highly significantly of p ≤ 0.05. Overall sex ratio (M: F = 0.52) was significantly different from the expected 1:1 ratio (p ≤ 0.05). The ovary weight and nidamental glands weight were 7.72 ± 0.0006 g and 3.07 ± 0.0003g respectively. Absolute and relative fecundity of the Indian squid were found to be 122733 ± 30.87 and 2348 ± 0.4 respectively. GSI were 14.35 in April and 8.63 in July. This squid is therefore a spring spawner. The infinite dorsal mantle length were 258.62 mm for females, 194.72 mm for males and 252.02 for both sexes respectively. For population growth and mortality parameters; K (0.65 per year for both sexes, 0.85 per year for males, 0.65 per year for females); t0 (0.24year for both sexes, 0.22 year in females, 0.26 year in male); φ` (2.30 in both sexes, 2.47 for males, 2.37 for females); Z (1.17 per year for both sexes, 1.10 per year in females, 1.39 per year, in males); M (0.70 per year for both sexes, 0.90 for males, 0.67 for females); F(0.27 per year for both sexes, 0.27 per year in males, 0.195 per year in females). Exploitation coefficient were 0.51 per year for both sexes, 0.57 per year males and 0.51 per year females respectively. The results indicates that since the Indian squid is a short live aquatic organism, therefore, the exploitation coefficient could be raised to 0.7 per year. The analysis showed that total biomass and MSY were 10103.5 ton and 2576.4 ton respectively. These findings are the first study of its sort about the Indian squid in the coastal waters of Oman Sea as well as North-West of Indian Ocean.

The major sources are identified and the Indicator of Coastal Eutrophication (ICEP) is calculated.

Copepods of the genus Hermilius (Caligidae) parasitic on marine catfish of Kuwait, with a key to the species of Hermilius

Three species of caligid copepods (Siphonostomatoida) belonging to genus Hermilius Heller, 1865 were recovered from the giant marine catfish, Arius thalassinus Ruppell, taken from the Persian Gulf. They are H. pyriventris Heller, 1865; H. longicaudus n. sp.; and H. longicornis Bassett-Smith, 1898. H helleri Pillai, 1963 is proposed to be relegated to the synonym of H pyriventris. A key to the eight species of Hermilius is provided.

A method of immersion of panels for ecological studies on marine fouling and boring organisms

The importance of studies on the biology of marine foulers and borers needs no emphasis since they cause damage to submerged wooden structures resulting in considerable economic loss. In order to study their occurrence, settlement and to assess the rate of destruction to timber, several immersion techniques using iron racks, cages and rafts have been adopted. On the east and west coasts of India, at the Marine Centres of Forest Research Institute (Waltair, Madras, Cohin and Bombay) investigations have so far been carried out employing the first two methods.
