Why in the Black sea has become a little fish?

Much worse than with the anchovy and sprats. is the case with the number of predatory fish in the Black sea. In the 1980-1990-ies completely disappeared the population of palamidi, tuna and mackerel. According to the hypothesis of the biologist Y. I. Sorokin from Noumea, on the annual migration paths of tuna and mackerel from the Marmara to the Black sea is irresistible “chemical barrier” is a giant city of Istanbul, all the waste of life in the city with a million residents flows directly into the waters of the Bosphorus. Not only Istanbul, but also all other Turkish seaside towns do not have sewage treatment facilities, resulting in pollution of the Black sea domestic and industrial wastewater.

At least 170 million people are living in all black sea countries, a tangible part of their waste of life and activity is in the Black sea.

Sewage of coastal cities, after cleaning, bring in the sea, it is harmless, even useful minerals that promote rapid plant growth. The trouble is that at the end of the twentieth century these nutrient mineral salts got into the Black sea too much, putting it on the brink of environmental catastrophe. Overfeeding marine ecosystems mineral salts is called eutrophication. The result of this, it is possible to observe on primarycontent sea of slime – filamentous unicellular green algae colonial green Alga, generously fueled by domestic sewage Anapa. The day the simplest tangle of seaweed balls almost doubled in size. In July in shallow water from Anapa to Blagoveschenskaya, grew a huge mass of seaweed balls, and reached 7500 tons! Unicellular algae kladofora prevents the growth of sea grass (eelgrass), green underwater meadows of eelgrass once covered all the sandy shallows. Balls unicellular colonial green Alga shade leaves of eelgrass, entangle and strangle its growth. The eelgrass meadow is the most beautiful underwater scenery and most lively habitat for various species of marine animals – crabs crustaceans-hermit crabs, seahorses, sea eagle, shrimp, etc. Continue reading

Flora and fauna

Over the past Millennium has developed this unique shape of the Black sea. This is the most fresh sea, with the lowest content of salt in sea water, the gentle sea-to-person around the globe!

In the composition of phytoplankton in the Black sea — not less than six hundred species. Among them, dinoflagellates — loricate flagellates (prorocentrum micans, ceratium furca, small scripsiella Scrippsiella trochoidea, etc.), dinoflagellates (dinophysis, protoperidinium, alexandrium), various diatoms, etc.

The fauna of the Black sea

The fauna of the Black sea is markedly poorer than the Mediterranean sea. In the Black sea is home to 2.5 million species of animals (including 500 videodnevnik, 160 species of vertebrates — fish, mammals, 500 species of crustaceans, 200 species of mollusks, and the rest — invertebrates of different species), for comparison, in the Mediterranean — about 9 thousand species.
