Furthermore, when transporting Litopenaeus vannamei shrimp, different shrimp larvae need to be classified according to size and packed into different transport boxes. However, because the transport boxes cannot be connected and fixed together, they cannot be stably stacked during transportation and are prone to shaking and impact when subjected to bumps.

This invention improves the stress resistance of Penaeus monodon by introducing anti-stress supplementary pellets and adding anti-stress components to the feed, thereby achieving a shrimp larvae survival rate of 40.9%, a body length of 30.6 mm, and a weight of 1.35 g, resulting in higher aquaculture yields and greater economic benefits for farmers.

This invention provides a rice-fish integrated farming method based on a double-rice, triple-shrimp model. It utilizes existing irrigation channels and raised paddy field embankments to increase the water level in the paddy fields without digging ditches, enabling grass planting and shrimp farming. The rice-shrimp integrated farming fields are divided into rice-shrimp co-cultivation and rice-shrimp rotation fields at a 2:5 area ratio. In the rice-shrimp co-cultivation fields, early rice is planted, broodstock shrimp are raised, and shrimp larvae are bred. In the rice-shrimp rotation fields, late rice is planted, and two crops of commercial shrimp are raised, providing high-quality broodstock for shrimp larvae breeding in the rice-shrimp co-cultivation fields. This integrated rice-fish farming model combines shrimp larvae bred in rice-shrimp co-cultivation with commercial shrimp farming in rice-shrimp rotation, forming an integrated farming model that produces one crop of early-bred shrimp larvae, two crops of commercial shrimp, and one season of double-variety rice annually. This invention pioneers a land-resource-saving and environmentally friendly rice-shrimp integrated farming development model with stable grain production and increased income, unique to Shanghai.

This utility model discloses a recirculating aquaculture system for white shrimp larvae rearing, relating to the field of white shrimp larvae rearing technology. The recirculating aquaculture system for white shrimp larvae rearing includes a rearing pond, an intercepting filter, and a sealing disc. The rearing pond is divided into upper and lower sections. The upper section has a straight hollow cylindrical structure, while the lower section has an inverted conical hollow structure, which reduces dead zones in the water flow and guides the water flow to form a uniform circulation. Simultaneously, the inverted conical lower section uses gravity to guide impurities to the bottom. The intercepting filter is embedded in the middle of the lower section of the rearing pond and is horizontally distributed. The intercepting filter is used to intercept shrimp larvae and allow impurities to pass through, preventing juvenile shrimp from being sucked in and damaged. The sealing disc is located on the top surface of the intercepting filter and can cover and seal the filter, causing impurities to accumulate on the disc rather than on the filter, thus preventing filter clogging.

This invention belongs to the field of aquaculture equipment technology, and particularly relates to a shrimp larvae acclimatization system for saline-alkali ponds. Addressing the problems of inaccurate water quality control and high stress during the multi-stage acclimatization process of shrimp larvae, the following solution is proposed: a salinity acclimatization tank, an ion acclimatization tank, and a water quality acclimatization tank are arranged sequentially along the acclimatization process, with transfer tanks between adjacent tanks. Each acclimatization tank is equipped with an independent water purification and conditioning component, capable of purifying the water in real time and precisely adding the required liquids, achieving closed-loop control through an integrated online water quality monitoring system. The salinity and ion acclimatization tanks have inflatable air bladders at the bottom; when inflated, these bladders raise the water level, allowing water to flow through the transfer tanks and form a waterway to induce shrimp larvae transfer. The transfer tanks are equipped with a water flow induction component that can switch flow directions to further assist the transfer. This invention achieves independent water quality control at multiple stages and enables low-stress, automated transfer of shrimp larvae.
