Breeding Experiment of Grass Carp from Different Sources in Northern Medium-Alkalinity Carbonate Ponds
Abstract：China has a vast area of low-lying saline-alkali waters, totaling 690 million mu. These waters are generally characterized by high carbonate alkalinity, high pH, and complex ion composition, making their development and utilization difficult, with over 90% being low-yield or abandoned. To address this issue, breeding new salt-tolerant fish varieties and promoting the 'fish farming to control alkali' model in a localized manner is of great significance for expanding suitable aquaculture areas, promoting the efficient use of non-arable land resources, and promoting farmers' income growth and ensuring the supply of high-quality aquatic products. Grass carp is the most produced major freshwater fish in China, favored by breeders for its fast growth and good meat quality. This study conducted a breeding experiment of grass carp from different sources in northern medium-alkalinity carbonate ponds, aiming to provide a reference basis for evaluating the salt tolerance of grass carp and breeding new salt-tolerant varieties.
