Dispersal is a crucial ecological process, driving population dynamics and defining the structure persistence of populations. Measuring demographic connectivity between discreet populations remains long-standing challenge for most marine organisms because it involves tracking movement pelagic larvae. Recent studies demonstrate local reef fish via dispersal planktonic larvae, while biogeography indicates some larvae must disperse 100–1000 s kilometres. To date, empirical measures...
We examined the influence of depth and stocking density on growth survival juvenile sea scallops (Placopecten magellanicus) in suspended culture at Gascons, Baie des Chaleurs. An increase greatly reduced shell, adductor muscle, other tissues, possibly because lower food availability diminished space. Growth was also influenced by greater 9 m than 21 m. However, effect largely masked fouling pearl nets. The pattern seasonal variations varied with parameter used to quantify growth, changes...

Characterizing degree hydrodynamic aperture mandatory for comparing functioning different lagoons.

The dynamics of potentially harmful phytoplankton in relation to environmental parameters was investigated the semi-enclosed Bay Bandar Khayran (Sea Oman) from April 2006 through 2011. In total, 24 algal species were identified, including 11 dinoflagellates and eight diatoms. Prorocentrum minimum (Pavillard) Schiller, 1933, Scrippsiella trochoidea Balech ex Loeblich III, 1965, Noctiluca scintillans (Macartney) Kofoid Swezy, 1921 most abundant during Southwest Monsoon (SWM, July-September)...
We used a high-resolution oxygen isotope (δ18Ocoral), carbon (δ13Ccoral) and Sr/Ca ratios measured in the skeleton of reef-building coral, Porites sp., to reveal seasonal-scale upwelling events their interannual variability Gulf Oman. Our δ13Ccoral record shows sharp negative excursions summer, which correlate with known events. Using anomalies as proxy for upwelling, we found 17 summer occurred last 26 years. These anomalous result from upwelled water depleted 13C (dissolved inorganic...
Ecosystems worldwide are suffering from climate change. Coral reef ecosystems globally threatened by increasing sea surface temperatures. However, gene expression plasticity provides the potential for organisms to respond rapidly and effectively environmental changes, would be favored in variable environments. In this study, we investigated thermal stress response Pocillopora coral colonies two contrasting environments exposing them heat stress. We compared physiological state, bacterial...
Larval connectivity relies on the ability of coral larvae to disperse into environment following ocean currents. At short timescales, larval plays a key role in resilience reefs, as it determines their capacity regain structure and function after major disturbances. longer time scales, controls distribution and, ultimately, biogeography species. We used Lagrangian stochastic model simulate transport routes released from reef communities Arabian Sea Gulf Oman. The surface currents two...
Abstract Inter-annual changes in temperature and chlorophyll a across the Arabian Sea (subdivided into 61 2-degree regions) were analysed. For each region, from appropriate databases, remotely sensed a, sea surface temperature, wind speed time series retrieved. Spatial temporal trend analysis showed physical–biological oscillations with dominant periods of 12 6 months (reflecting seasonality monsoonal winds) globally warming trend, but no overall increase during period 1997–2009. Variation...
A rapid survey of the density and size distribution recently exploited populations Holothuria scabra in Mahout Bay (Ghubbat Hashish Bay) was carried out at six fishing sites. The results showed that population densities varied between 1170 4000 individuals ha-1 biomass ranged 393 2903 kg ha-1. mean sea cucumbers were much lower closer to human settlements, suggestive overfishing. sex ratio estimated be 1:1 distributions males females did not differ significantly. length-weight relationship...
Intraspecific chemical communication between echinoderms has often been limited to prespawning aggregation. However, sea cucumber farmers have long observed year-round adult aggregation as a potential source of disease propagation and the suboptimal use available pen acreage food resources. In this study, through spatial distribution statistics, we demonstrated significant aquacultivated Holothuria scabra both adults in large sea-based pens juveniles laboratory-based aquaria, proving that...
