Abstract
Lais fish (Kryptopterus palembangensis) is one of the endemic fish in South Sumatra. The availability of lais fish in nature began to decline because continuous fishing by the community would interfere with the sustainability of lais fish. It is known that high economic value is the cause. Therefore, efforts need to be made to develop lais fish farming so that it can be produced in a controlled manner. The writing method used is a literature study. The technology and management of lais fish include differences in stocking density in floating net cages, feeding different types of feed, soaking larvae in probiotic solutions, the influence of temperature differences and maturation of gonads with Fe minerals. Then for the average water quality in the growth of lais fish is a temperature of 25.2-32ºC, a pH range of 4.7-7.9, DO 2.6-8 mg.L-1 and ammonia content ranging from 0.010-2 mg.L-1. Lais fish belong to the group of carnivorous fish because its main types of food are small fish, insecta and shrimp. In fish studied in a controlled manner, feed using tubifex sp. provides the highest growth and survival. Spawning of wedge lais fish (Kryptopterus palembangensis) once a year with a total spawning pattern of spawners in the rainy season where at the time of splashing water begins to rise and spawning is carried out in the crevices of the rocks. The picture of blood cells is a supporting aspect in determining the health status of fish. The physiological condition of healthy fish is characterized by the presence of increased growth. Physiological growth of lais fish in a healthy state i.e., total erythrocytes 264±3.0x104 cells mm-3, hemoglobin 8.3±0.11 g/dL, hematocrit 26.66±0.57%, total leukocytes 2.53±0.01 x 104 cells mm-3 and Blood glucose 89.00 ± 1.00 mg / dL
