Abstract

Jade perch (Scortum Barcoo) is a highly nutritious fresh water bass species native in Australia and now being a promising candidate for aquaculture in China. To provide a fundamental biological basis for future germplasm improvement and exploitation of jade perch, biological characteristics of jade perch, including propagation, morphological and genetic characters were analyzed in this study. Jade perch becomes sexually mature at four-year-old. Zygotes of jade perch are transparent, buoyant, and swell upon absorption of water to up to 2.1±0.3mm in diameter. At a water temperature of 27.5±2°C, zygoteshatched 21-26h after fertilization. Comparison of morphological characters between two- and six-month-old jade perch revealed that the proportion of the head with respect to the body decreased significantly (P
