Tropical commercial sea cucumber Stichopus horrens is extensively distributed throughout the tropical Indo-Pacific region, and wild stocks have been severely depleted over the past decade. In this study, we used the microsatellite enrichment library of S. horrens to identify and characterize 13 microsatellite loci, including 11 polymorphic loci and 2 monomorphic loci. Among the 11 polymorphic l...

The ctenophore Bolinopsis vitrea is first reported from the Turkish and Bulgarian regions of the Black Sea. In Turkish waters, a considerable aggregation was found in Sile on the Asian side and at Kilyos on the European side in 2007. This appears to be the first record of this species in the Black Sea, which is known in the Mediterranean Sea including the Aegean Sea. Bolinopsis vitrea most like...

Changes in the color of sea water caused by algal bloom has continuously risen in recent decades. This increase is due to the harmful effects of human activities that allow sea water to change from a normal to an abnormal state. Satellite sensors are the most accessible, cost-effective means of monitoring. They have been allocated to a large number of marine science studies. The MODIS satellite...

  Eviscerated sea bass, Dicentrarchus labrax were irradiated by Cobalt-60 at commercial irradiation facility at dose of 2.5 and 5 kGy at 2–4°C. The influences of the irradiation on proximate, fatty acid and amino acid composition in cultured sea bass were investigated. Significant differences (P<0.0.5) were found between non-irradiated and irradiated sea bass in terms of moisture, protein, fat,...

Studies on echinoderms along the Panamanian Pacific coast have focused mainly on evolutionary and molecular analyses, however little ecological research has been done and mainly only on 2 species: Diadema mexicanum and Acanthaster planci. Herein, we describe for the first time the diversity (based on Margalef, Shannon and Pielou indices), distribution and density of echinoderms for some islands...

BACKGROUND There is growing interest in mining polymetallic nodules from the abyssal Clarion-Clipperton Zone (CCZ) in the tropical Pacific Ocean. Despite being the focus of environmental studies for decades, the benthic megafauna of the CCZ remain poorly known. In order to predict and manage the environmental impacts of mining in the CCZ, baseline knowledge of the megafauna is essential. The AB...

Changes in the quality or quantity of food can have a dramatic effect on the population status of wild animals. Unfortunately, it is difficult to assess (or define) whether nutritional stress is a contributing factor to the decline of any particular species. The “nutritional quality” of a diet to an animal is a complex matter to assess given the range of components that can influence its value....

In this paper the main factors that influence the Caspian Sea level rising and the probable and improbable factors are discussed in detail. A cyclical behavior of the level of the Caspian Sea according to local records was proposed. This cyclic fluctuation of the sea level is the long-term behavior of the sea so that the investigation is not restricted to a specific time interval. The statistic...

Sea-ice hazard causes serious harm to aquaculture, marine navigation, offshore oil production and other activities in the Bohai Sea, China. To study the spatial distribution characteristics of sea-ice-hazard risk in Bohai is therefore desirable. The thickness and area of sea ice in the Bohai Sea during the winters (December–March) of 1987–2011 were estimated using data from the NOAA (US Nationa...
