Background
Bullfrog (Rana catesbeian) belongs to Amphinaceae, Anhula, Ranidae, and is a large edible frog because it sounds like a cow. The bullfrog is originally produced in North America, Mexico and other places, is introduced into China from Guba in 1959, and has the advantages of rich nutrition, delicious taste, high growth speed and strong environment adaptability. In 2019, the bullfrog breeding yield is close to 50 million tons, the direct sale yield exceeds 50 million yuan per year, and the bullfrog breeding method becomes an important famous variety for aquaculture in China.
Fish meal is a high-quality protein source which is generally accepted for a long time because of high protein content, abundant and balanced amino acids, rich fatty acids (especially EPA and DHA) and unknown growth factors, good palatability and easy digestion. The rapid development of intensive culture in the present generation leads to increasing demand of fish meal. However, due to the influence of factors such as resource attenuation, bad climate and over fishing, the global fish meal yield fluctuates between 500-. The fish meal yield can not meet the requirement of compound feed production more and more, the price is high due to the contradiction between supply and demand, and the breeding cost is increased, which has become a major problem for limiting the sustainable development of the aquaculture industry.
At present, the using amount of fish meal in commercial bullfrog feed is generally more than 10%, the fish meal cost accounts for a large proportion of the total cost of the feed, so that the breeding cost is high, the breeding benefit is low, and the large-scale breeding of bullfrogs is limited to a great extent.
