Cirrhinus microlepis (English Smallscale Mud Carp) is a medium-sized carp fish from Indochina . It is called Kalang or Trey Kalang in Cambodia, Pa Pawn in Laos and 小 鱗 鯪 in China.
description
Cirrhinus microlepis differs from other species of the genus Cirrhinus by its 53 to 60 scales on the sidelines. It is a large fish species with very small scales, no barbels and an intense color that varies widely. In juvenile fish it is still silvery with red tail fins, adult specimens can be purple, purple, pink to bluish with dark fins on the head and body. Its fin formula is: Dorsal 15–16. The fish are on average 60 centimeters long. The catch of a fish weighing 5 kilograms and 65 centimeters in length from the Srinakarin Reservoir in Thailand is guaranteed, but also specimens weighing 15 kilograms and one meter in length.
distribution
Cirrhinus microlepis is distributed in the river systems of the Mekong and Mae Nam Chao Phraya in Thailand , Laos , Cambodia and Vietnam .
Way of life
Cirrhinus microlepis mainly inhabits tropical rivers and temporary flood plains in the lowlands of Indochina. He likes to be near rapids and deep reservoirs. In the rainy season, the species migrates to the flooded rainforests and feeds on leaves, other plant material, phytoplankton and insects. His various hiking patterns above and below the Khone Falls have been documented. Between November and February juvenile fish and subadults in sizes 10 to 50 centimeters migrate upriver towards the Mekong Falls at the height of Phnom Penh . From April to July the migration takes place downstream in the opposite direction. Above the Mekong Falls, the upstream migration begins staggered from the Klong Kaem District, Ubolratchatani in Thailand in February, at Khemmaratch in March / April, at Mukdahan in May and at Klong Kaem in June / July. The downstream migrations of the fish reach as far as the Mekong Delta in Vietnam, where a large number of juvenile fish in lengths of two to 20 centimeters can be found. From Xayabouri in Laos to Chiang Saen in Thailand, two migrations of fish begin in different stages of development from March to August. During the dry season , the deep pools of the Mekong, as a retreat, play a crucial role in the survival of Cirrhinus microlepis .
use
Cirrhinus microlepis is used as a sport fish for anglers and edible fish. It is kept in cages and then marketed fresh, salted or dried. Numerous efforts are being made to prevent the species from becoming extinct. Among other things, the effects of gill net fishing on the population of Cirrhinus microlepis were examined . There are efforts to preserve fish sperm / fish milk from Cirrhinus microlepis and attempts to keep the fish in a pond. The latest breeding successes with wild strains of Cirrhinus microlepis in Laos give hope that the species will continue to exist.
