Ecological culture method for sea shrimps

The invention provides an ecological culture method for sea shrimps. The method comprises the following steps: (1) carrying out field plowing and preparation and disinfecting; (2) carrying out rice seedling transplanting and fertilizer application; (3) carrying out traditional Chinese medicine medicated liquid application; (4) stocking the sea shrimps after rice seedlings turn green; (5) carrying out feedstuff feeding; and (6) keeping water fresh and clean, and keeping the water level of rice fields to 60cm to 70cm in a rapid growing stage of the sea shrimps. According to the method, sea shrimp culture and rice planting are organically combined, and the sea shrimps and rice are in mutualism, so that the productivity of farmland is brought into full play, and the economic benefit of farmland operation is improved. According to the method, the medicated liquid is applied before stocking juvenile shrimps, so that the disease resistance of the sea shrimps can be enhanced, the immunity is improved, and the case rate of the sea shrimps is decreased by 6% to 9% compared with that cultured without applying the medicated liquid; and feedstuff for the juvenile shrimps and feedstuff for adult shrimps can excellently meet the nutritional requirements of the sea shrimps in all growth stages, the shrimps grow rapidly after the shrimps eat the feedstuff, and compared with the delivery of only one kind of feedstuff, the growth speed is increased by 4% to 6%, and the yield per mu is increased by 3% to 5%.
