Fish Tour: October 2009

Hout Bay,Cape Town South Africa

Mould Bay,Prince Patrick Islands

Hudson Bay was the growth center for the main ice sheet that covered northern North America during the last Ice Age. The whole region has very low year round average temperatures. (The average annual temperature for Churchill at 59°N is -5°C;

Caspian Sea

Caspian Sea is the largest enclosed body of water on Earth by area,variously classed as a the worlds largest lake or a full fledged sea. It has a surface area of 371,000 square kilometers (143,244 sq mi) and a volume of 78,200 cubic kilometers (18,761 cu mi). It has no outflows.

The Caspian Sea borders Azerbaijan,Iran,Kazakhstan,Russia and Turkmenistan.

Brahmaputra River,Tibet Asia

When compared to the other major rivers in India, the Brahmaputra is less polluted but it has its own problems: petroleum refining units contribute most of the industrial pollution load into the basin along with other medium and small industries. The main problem facing the river basin is that of constant flooding. Floods have been occurring more often in recent years with deforestation, and other human activities being the major causes.

About 1,800 miles (2,900 km) long, the river is an important source for irrigation and transportation. Its upper course was long unknown, and its identity with the Yarlung Tsangpo was only established by exploration in 1884-86. This river is often called Tsangpo-Brahmaputra river. The average depth of river is 124 feet (38 m) and maximum depth is 380 feet (120 m).

Lake Tanganyika,Africa

It is estimated that 25–40% of the protein in the diet of the people living around the lake comes from lake fish,and that population amounts to around one million.Currently there are around 100,000 people directly involved in the fisheries operating from almost 800 sites. The lake is also vital to the estimated 10 million people living in the basin.
Lake Tanganyika fish can be found exported throughout East Africa. Commercial fishing began in the mid-1950s and has had an extremely heavy impact on the pelagic fish species, in 1995 the total catch was around 180,000 tonnes. Former industrial fisheries, which boomed in the 1980s, have subsequently collapsed.

The lake holds at least 250 species of cichild fish and 150 non-cichlid species, most of which live along the shoreline down to a depth of approximately 180 metres (590 ft). Lake Tanganyika is thus an important biological resource for the study of speciation in evolution. The largest biomass of fish, however, is in the pelagic zone (open waters) and is dominated by six species: two species of tangananyika sardine and four species of predatory lates (related to, but not the same as, the Nile perch that has devastated Lake Victoria cichilds.)
crabs, shrimps,jellyfishes, leeches, copepods. Almost all (98%) of the Tanganyikan cichlid species are endemic (exclusively native) to the lake and many, such as fish from the brightly coloured Tropheus genus Prized within the aquarium trade. This kind of elevated endemism also occurs among the numerous invertebrates in the lake, most especially the molluscs.

Blondulon Lake,Iceland

Blondulon Lake is one of the largest lakes in Iceland.

Qinghai Lake,China

There is an island in the western part of the lake with a temple and a few hermitages called "Mahādeva, the Heart of the Lake" (mTsho snying Ma hā de wa) which historically was home to a Buddhist monastery.
It is also known as the place where Gushri Khan and other Qoshot Mongols, of the Oirat or Dzungar Mongols, migrated to during the 1620s.
