Abstract: This paper analyzed the nutritional components and amino acids composition of black and white fleshcolored golden apple snails (Pomacea canaliculata） collected from different habitats (fish pond, ditch, and paddy field), aimed to compare the differences in the nutritional components of these snails and explore the potential utilization values of the snails during the process of integrated control. The snails in fish pond had the highest contents of water and crude fat, those in ditch had the highest ash content, while those in paddy field had the lowest contents of water, crude fat, and crude protein. The crude protein content of the snails in ditch and pond was higher than 13%, and the snails in pond had the highest contents of total amino acids, essential amino acids, and flavor amino acids and the highest index of essential amino acids, but the proportion of essential amino acids was the lowest. The snails in paddy field had higher contents of essential amino acids and flavor amino acids than the snails in ditch, and the index of the essential amino acids of the snails in different habitats was in the order of fish pond > paddy field > ditch. Overall, white flesh snails had higher nutritional values than black flesh ones, and the nutritional composition of the snails essential amino acids was similar to that of fish meal (CP 53.5%). It was suggested that in the utilization of golden apple snails, their flesh color and origin should be fully considered.
