Protomelas Kirkii
''Protomelas kirkii'' is a species of cichlid endemic to Lake Malawi, where it is most commonly found in areas vegetated with ''Vallisneria''. This species can reach a length of TL. It can also be found in the aquarium trade. Description This cichlid fish is relatively deep-bodied, with a small mouth and a yellow-brown colour with an obvious horizontal flank stripe. It often lives together with the similar-looking '' Protomelas similis'' and '' P. labridens''. ''Protomelas kirkii'' can be distinguished by its longer snout and small terminal (forward-facing) mouth. Females and immatures are countershaded, yellowish-brown on the upper surface, and paler on the flanks and underside. There is a strong dark horizontal stripe along the midline, and sometimes a thinner dark band about half-way between the midline band and the base of the dorsal fin. There are often dark blotches along the base of the dorsal fin. Faint dark vertical bars can sometimes be seen on the flanks. The tip of ...

David Livingstone
David Livingstone (; 19 March 1813 – 1 May 1873) was a Scottish physician, Congregationalist, and pioneer Christian missionary with the London Missionary Society, an explorer in Africa, and one of the most popular British heroes of the late 19th-century Victorian era. David was the husband of Mary Moffat Livingstone, from the prominent 18th Century missionary family, Moffat. He had a mythic status that operated on a number of interconnected levels: Protestant missionary martyr, working-class "rags-to-riches" inspirational story, scientific investigator and explorer, imperial reformer, anti-slavery crusader, and advocate of British commercial and colonial expansion. Livingstone's fame as an explorer and his obsession with learning the sources of the Nile River was founded on the belief that if he could solve that age-old mystery, his fame would give him the influence to end the East African Arab–Swahili slave trade. "The Nile sources", he told a friend, "are valuabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seine Fishing
Seine fishing (or seine-haul fishing; ) is a method of fishing that employs a surrounding net, called a seine, that hangs vertically in the water with its bottom edge held down by weights and its top edge buoyed by floats. Seine nets can be deployed from the shore as a beach seine, or from a boat. Boats deploying seine nets are known as seiners. Two main types of seine net are deployed from seiners: ''purse seines'' and ''Danish seines''. A seine differs from a gillnet, in that a seine encloses fish, where a gillnet directly snares fish. Etymology The word ''seine'' has its origins in the Old English ''segne'', which entered the language via Latin ''sagena'', from the original Greek σαγήνη ''sagēnē'' (a drag-net). History Seines have been used widely in the past, including by Stone Age societies. For example, the Māori used large canoes to deploy seine nets which could be over a kilometer long. The nets were woven from green flax, with stone weights and light wood o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish As Food
Many species of fish are caught by humans and consumed as food in virtually all regions around the world. Fish has been an important dietary source of protein and other nutrients throughout human history. The English language does not have a special culinary name for food prepared from fish like with other animals (as with ''pig'' vs. ''pork''), or as in other languages (such as Spanish ''pez'' vs. '' pescado''). In culinary and fishery contexts, ''fish'' may include so-called shellfish such as molluscs, crustaceans, and echinoderms; more expansively, seafood covers both fish and other marine life used as food. Since 1961, the average annual increase in global apparent food fish consumption (3.2 percent) has outpaced population growth (1.6 percent) and exceeded consumption of meat from all terrestrial animals, combined (2.8 percent) and individually (bovine, ovine, porcine, etc.), except poultry (4.9 percent). In ''per capita'' terms, food fish consumption has grown from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spawn (biology)
Spawn is the Egg cell, eggs and Spermatozoa, 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 marine reptile, 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 Ovum, 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 mos ...

Mouthbrooder
Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time. Although mouthbrooding is performed by a variety of different animals, such as the Darwin's frog, fish are by far the most diverse mouthbrooders. Mouthbrooding has evolved independently in several different families of fish. Mouthbrooding behaviour Paternal mouthbrooders are species where the male looks after the eggs. Paternal mouthbrooders include the arowana, various mouthbrooding bettas and gouramies such as ''Betta pugnax'', and sea catfish such as ''Ariopsis felis''. Among cichlids, paternal mouthbrooding is relatively rare, but is found among some of the tilapiines, most notably the black-chin tilapia ''Sarotherodon melanotheron''. In the case of the maternal mouthbrooders, the female takes the eggs. Maternal mouthbrooders are found among both African and South American ci ...

Lake Malombe
Lake Malombe is a lake in southern part of Malawi, on the Shire River, in the Southern Region, Malawi, Southern Region. It is located at around , about south of much larger Lake Malawi. It has an area of about . In recent years the number of fishermen on the lake rose substantially, and this led to local decline in some fish species, especially the Oreochromis, chambo cichlids which is an important source of food throughout Malawi. The lake is extremely shallow with an average depth of approximately eight feet, and during periods of dry weather the water level recedes and can even disappear. The lake-bed was dry for several hundred years until it refilled in the middle of the 19th century.

Kapachira Falls
Kapachira Falls are waterfalls in Malawi. They lie on the lower Shire River near the town of Chikwawa and the Majete Wildlife Reserve. The Kapichira Hydroelectric Power Station was constructed above the falls to provide hydroelectricty. During his 1859 Zambezi Expedition, David Livingstone named them the Murchison Cataracts after the geologist Sir Roderick Murchison Sir Roderick Impey Murchison, 1st Baronet, (19 February 1792 – 22 October 1871) was a Scotland, Scottish geologist who served as director-general of the British Geological Survey from 1855 until his death in 1871. He is noted for investigat .... His river steamer ''Ma Robert'' could not pass them to get further up the Shire; several members of his team died from disease and are buried in the area.

Shire River
The Shire is the largest river in Malawi. It is the only outlet of Lake Malawi and flows into the Zambezi River in Mozambique. Its length is . The upper Shire River issues from Lake Malawi and runs approximately before it enters shallow Lake Malombe. It then drains Lake Malombe and flows south through Liwonde National Park where large concentrations of hippopotamus are common along its shores. Between the towns of Matope and Chikwawa, the middle river drops approximately through a series of falls and gorges, including Kapachira Falls. Two hydroelectric dams have been built along the Shire northwest of Blantyre. Beyond Chikwawa, the lower river turns southeast and enters the low-lying Mozambique plain. Its largest and one of its few perennial tributaries, the Ruo River, joins the Shire near the Malawian town of Chiromo. The muddy waters pass through a large stagnant area known as the Elephant Marsh before reaching the confluence with the Zambezi River south of the town of Sen ...
