一、亲虾采捕的方法:我社采捕亲虾的网具是拉网、对网、对虾流网、插网、地网、撩网等五种,随着水温的变化和亲虾的洄游适当地选用。过小满后,温度较低,对虾一般在13—14拓水层,这时应用拉网,到较深较远的海区去采捕;在水温上升到18—20℃时,就得采用对虾流网到3—4拓水深的地方捕捞;水温继续上升到20—25℃时,亲虾大部份洄游到海边索饵和寻找产卵场所,这时就用插网、地网、撩网采捕。这些网具中,以插网、地网、撩网较好,在采捕中不会损伤虾
First, the method of collecting the broodstock: I collected the broodstock netting tools is pulling the net, the net, prawn flow network, intercalated network, network, network and other five, with changes in water temperature and migration of broodstock Appropriate selection. After a small full, the temperature is lower, the shrimp is generally 13-14 water layer, then pull the net, to the deeper farther the sea to capture; the water temperature rose to 18-20 ℃, you have to use shrimp stream The network to 3-4 to develop deep water fishing; water temperatures continue to rise to 20-25 ℃, most of the migratory shrimp to the seaside bait and find spawning sites, then use the network, the network, catch. Among these nets, it is better to insert nets, net nets and nets, which will not damage shrimp during harvesting
