Sukhyi Estuary
Sukhyi Estuary, or Sukhyi Lyman ( uk, Сухий лиман - dried estuary), is on open estuary in the north-western Black Sea, near the cities of Odesa and Chornomorsk, Ukraine. In 1957 the estuary was connected to the sea via 14-m depth navigation canal, therefore the water body de facto transformed to the marine bay. Upper site of the estuary is more shallow, up to 1.5 m depth. Northern and western parts are separated by artificial dam and transformed to fresh water ponds. The Dalnyk River inflows to the estuary. The modern name, "Dry Estuary", the water body have got in the time when it was isolated from the Black Sea. That time the estuary dried regularly, sometime up to 1 km² area. The earlier name is Kleinliebenthal Estuary, origine from the german: Kleinliebenthal, "Small valley of love". The name of the water body is given by German colonists. The upper part of the estuary is located in two valleys: * ''Kleinliebenthal'', "Small valley of love". The main part of t ...

Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...

Spawning
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring. The process of spawning typically involves females releasing ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa (milt) to fertilize the eggs. Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mosquitoes and corals, which are actually small ...

Estuaries Of The Black Sea
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, harb ...

Mullet (fish)
The mullets or grey mullets are a family (Mugilidae) of ray-finned fish found worldwide in coastal temperate and tropical waters, and some species in fresh water. Mullets have served as an important source of food in Mediterranean Europe since Roman times. The family includes about 78 species in 20 genera. Mullets are distinguished by the presence of two separate dorsal fins, small triangular mouths, and the absence of a lateral line organ. They feed on detritus, and most species have unusually muscular stomachs and a complex pharynx to help in digestion. Classification and naming Taxonomically, the family is currently treated as the sole member of the order Mugiliformes, but as Nelson says, "there has been much disagreement concerning the relationships" of this family. The presence of fin spines clearly indicates membership in the superorder Acanthopterygii, and in the 1960s, they were classed as primitive perciforms, while others have grouped them in Atheriniformes. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atherina Boyeri
The big-scale sand smelt (''Atherina boyeri'') is a species of fish in the family Atherinidae. It is a euryhaline amphidromous fish, up to 20 cm in length. Description It is a small pelagic fish species which occurs near the surface in the littoral estuarine zone: in lagoons, salt marshes (77 psu), shallow brackish areas (2 psu) and inland waters which are rather unsuitable for other fish species, due to their high ionic strength and salinity. Body is rather long, slender, moderately flattened. Eyes are large. Head and body are scaly. Mouth is protractible, upwardly directed, with small teeth. Lower jaw has an upper expansion within mouth (high dentary bone). There are two separate dorsal fins, with all rays of first and 1-2 anterior rays of second dorsal fin being unsegmented. The anal fin is similar to the second dorsal fin, while the caudal fin is forked. The first dorsal fin has 6-10 flexible spines. It is an omnivorous species feeding on zoo-plankton and small bottom-l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grass Goby
The grass goby (''Zosterisessor ophiocephalus'') is a species of goby native to the Mediterranean Sea, the Sea of Azov and the Black Sea. It is currently the only known member of its genus. Characteristics Grass gobies can grow up to long. The head crown, nape, throat, belly, and bases of the pectoral fins are covered by cycloid scales and the gill covers are naked. The abdominal sucker has no blades and does not reach the anus. The mandibulae are protrusive, and the skin soft, with mucus. Their coloration is green-brown, patterned with merging brown spots.

Gobies
Gobiidae or gobies is a family of bony fish in the order Gobiiformes, one of the largest fish families comprising more than 2,000 species in more than 200 genera. Most of gobiid fish are relatively small, typically less than in length, and the family includes some of the smallest vertebrates in the world, such as '' Trimmatom nanus'' and ''Pandaka pygmaea'', ''Trimmatom nanus'' are under long when fully grown, then ''Pandaka pygmaea'' standard length are , maximum known standard length are . Some large gobies can reach over in length, but that is exceptional. Generally, they are benthic or bottom-dwellers. Although few are important as food fish for humans, they are of great significance as prey species for other commercially important fish such as cod, haddock, sea bass and flatfish. Several gobiids are also of interest as aquarium fish, such as the dartfish of the genus ''Ptereleotris''. Phylogenetic relationships of gobiids have been studied using molecular data. Descript ...
