稻田养蟹,如果投放豆蟹,当年起捕的成蟹规格小,卖不出好的价钱;如果投放扣蟹,当年起捕的成蟹一般每只在100—150g,规格大,价格高。但是,由于扣蟹比豆蟹大,而刚栽下田的嫩秧苗,正是扣蟹的适口饵料,因此,扣蟹喜食,轻则将嫩秧苗吃得残缺不全,严重的会将嫩秧苗吃得所剩无几。 If crabs are put in paddy fields, crabs with small crabs will not be sold at a good price. If crabs are delivered, those crabs caught in that year will generally have a size of 100-150g each, with large specifications and high prices. However, since crabs are larger than bean crabs, the tender seedlings that have just been planted in the fields are the bait for crabs. Therefore, if you eat crabs, they will eat the tender seedlings incompletely, and the serious ones will eat tender seedlings There is not much left.
