近年来,随着网箱养鱼模式的发展,一些地区又试用网箱养虾获得高产,而且方法简易。一、育苗选体壮、抱卵多的雌虾,放入网目较稀(9—12目/厘米~2)、面积2米~2的浮式小箱内孵化。小箱放在密目网箱中,使孵出的蚤状幼体落入大箱中生长。两种箱均置少量水草。大箱每天泼豆浆2次。15天后可增投少量麦粉,25天左右幼苗出箱。二、网箱以长方形10×6.67米为宜。网箱水下深0.9—1.0米为好,防逃网应高出网箱0.4米,网目为169目/厘米~2。箱壁箱底用24目/厘米~2为优。网箱排列间距4—5米,行距5—6米。箱内可置些水葫芦,以供栖息。
In recent years, with the development of the cage fish culture mode, some areas try out high-yield cage shrimp farming again, and the method is simple. First, nursery election body strong, spawning females, into the mesh more dilute (9-12 mesh / cm ~ 2), an area of 2 m ~ 2 floating small box hatch. Small cages placed in a cage in the cage, hatched flea larvae fall into the big box growth. Both boxes are placed a small amount of aquatic plants. Large box of milk twice a day. After 15 days can increase investment a small amount of wheat flour, 25 days seedlings out of the box. Second, the cage to rectangular 10 × 6.67 meters is appropriate. Cages underwater 0.9-1.0 meters deep as well, Fangtao network should be higher than 0.4 meters cage, mesh 169 mesh / cm ~ 2. Box wall bottom with 24 mesh / cm ~ 2 is excellent. Cages arranged 4-5 m spacing, spacing 5-6 meters. Box can be set some water hyacinth, for the habitat.
