Starfish contains a large number of conventional substances such as protein, amino acids, unsaturated fatty acids, calcium, iron and phosphorus, and also contains substances with special effects such as starfish saponin and starfish saponin.
Compared with sharks, the content of unsaturated fatty acids in starfish is not very high, but it is also much higher than that of animals growing on land. It is suitable for the elderly to eat in moderation, which can enhance memory, strengthen brain and improve intelligence.
Main hazards:
More than half of the 25,000-square-kilometer coral reefs in the Philippines were attacked by starfish. Starfish are also terrible. A large number of starfish suddenly broke out in the northern coastal area of China, with a density as high as 300/m2. During the peak period, more than 500 kilograms of starfish can be picked and caught in the 3-5 mu sea area every day.
Starfish are mainly concentrated in Laoshan Mountain, Jiaozhou Bay, Tangdao Bay and Jiaonan sea area, and frantically eat abalone, Philippine clam, scallop and other cultured economic shellfish. One starfish 1 day can eat more than a dozen scallops, and the food intake is amazing, causing huge economic losses to shellfish farming.
The loss of abalone culture in Jiaonan area caused by starfish disaster reached more than 40 million yuan; In 2007, only the variegated clam culture of Qingdao Haifeng Aquaculture Company lost more than 30 million yuan due to starfish swallowing.
