The silver or Java barb ( Barbonymus gonionotus ) is a medium-sized carp fish from Indochina . It is also called Silver Barb or Thai Silver Barb in English, is called Thai Sharputi in Bangladesh, Keputihan in Indonesia, Pla Ta Pien Khao ( Thai ปลาตะเพียน ขาว ) in Thailand and in Malaysia Tawes, Lawak, Lampam Jawa or Lalawak.
description
Silver barbs are characterized by an intense silver color all over their body, the back area can be colored golden brown or light blue. The dorsal and pelvic fins are yellow and gray, the anal fin light orange. The fin tips can sometimes be red. The sturdy rhombus-like body is strongly compressed, the back is curved. The fish has a small head and a pointed mouth. The barbels are only rudimentary. His fin formula is: dorsal 8-8, anal 6-7. Under most environmental conditions, the fish only grow to around 40 centimeters, but in exceptional cases they are much larger. A specimen weighing 2.80 kilograms was caught in Teak Tree Lake in Thailand and specimens weighing 13 kilograms and a body length of around 90 centimeters in Malaysia.
distribution
Barbonymus gonionotus is widespread in Thailand , Laos , Vietnam , Cambodia , Malaysia , Singapore and Indonesia : Sumatra , Java and Borneo . The main distribution area is the river basin of the Mae Nam Chao Phraya and the Mekong . The fish species live in the Mekong from Chiang Kong in Thailand to the brackish water zone of the Mekong Delta . In addition, the Java bar was introduced in numerous Asian countries such as Bangladesh , the Fiji Islands, Myanmar , the Philippines and India .
Way of life
The silver mullet, which occurs in swarms, prefers tropical streams, rivers and lakes with a water temperature of 22 to 28 ° C. It prefers the mean water or stays on the bottom at greater depths. In his search for food he also wanders on flood plains, flooded gallery forests during the rainy season and in reservoirs. He prefers standing water over fast flowing water. Its diet consists of plant residues such as leaves from, for example, Ipomea reptans and hydrilla or small animals. B. gonionotus is considered a migratory fish, but it does not cover very long distances like other fish species in the Mekong. There are local migrations in tributaries and canals of the main stream during floods, if the water level falls, silver mullets retreat back into the main stream. Introduced fish that escape from managed ponds can often reproduce rapidly in wild waters, as has happened on some Southeast Asian islands.
Use
The silver mullet is a sport fish for anglers and edible fish. After grinding the bones, the freshly prepared fish is sold as lap pa or grilled as som pa in local markets. Java barbs are often used in overgrown reservoirs to destroy aquatic plants. In Bangladesh, the species was introduced from Thailand and established in aquaculture. Studies have also been carried out in Cambodia to increase the productivity of Barbonymus gonionotus in smallholder pond farming. Java barbs can also be kept in aquariums.
