Channa

Channa is a genus of the Channidae family of snakehead fish. This genus contains 34 scientifically described species, but the most well known are probably the northern snakehead (Channa argus) and the giant snakehead (Channa micropeltes). Channa has a wide natural distribution extending from Iran in the west, to China in the east, and parts of Siberia in the Far East. They are one of the most common staple food fish in Thailand, Cambodia, Vietnam, and other South East Asian countries, where they are extensively cultured. Apart from their importance as a food fish, snakeheads are also consumed as a therapeutic for wound healing as well as reducing post-operative pain and discomfort, and collected for the international aquarium pet trade. The diets of various species of Channa include fish, frogs, snakes, rodents, birds, and insects. Some can move on land like snakes, and breathe air.

The taxonomy of the genus Channa is incomplete and a comprehensive revision of the family has not been performed. A phylogenetic study in 2010 has also indicated the likelihood of the existence of more undescribed species of channids in South East Asia. In June 2011, the Malabar snakehead Channa diplogramma from peninsular India was shown to be a distinct species, 146 years after its initial description and 134 years after it was synonymised with C. micropeltes, establishing it is an endemic species of peninsular India. The study also suggested that the species shared a most recent common ancestor with C. micropeltes, around 9.52 to 21.76 MYA.

Đắk Lắk Province

Đắk Lắk ( listen) is a province of Vietnam. The name is also spelled Đắc Lắc, which is more in keeping with Vietnamese spelling, and occasionally Darlac, but the official spelling is Đắk Lắk. It is located in Vietnam's Central Highlands, and is home to a high number of indigenous people who are not ethnically Vietnamese (Việt).

History

The area now known as Đắk Lắk was originally controlled by the Kingdom of Champa. When Champa was conquered and annexed by Vietnam in the 15th century, Đắk Lắk was brought under loose Vietnamese rule. Later, in 1540, a noble named Bùi Tá Hán was appointed by the Vietnamese authorities to direct the settlement of the area by ethnic Vietnamese, bringing the highlands under more effective Vietnamese control. Military outposts were established in the area to guard against possible aggression from the west. Later, when Vietnam was occupied by the French, the French established a large number of plantations in the area. Resistance to French rule was strong in Đắk Lắk, with various minority tribes leading a number of significant rebellions. The most notable was a 23-year campaign led by N’Trang Lơng, a M’Nông tribal leader. Later, Đắk Lắk was part of South Vietnam, and saw considerable action in the Vietnam War.
