Description

Technical Field The present invention pertains to the technical field of crayfish aquaculture, specifically to a feed for crayfish aquaculture and a method for crayfish aquaculture. Background Technology Crayfish are highly favored by consumers for their delicious taste and substantial nutritional value. With the improvement of living standards and consumer preferences evolve, the demand for crayfish has been steadily increasing year over year. Therefore, crayfish aquaculture not only meets market demand but also promotes the development of associated industries, thereby contributing to local economic growth. Additionally, crayfish aquaculture creates employment opportunities, enhances farmers income, and fosters rural economic prosperity. Existing crayfish feeds and aquaculture methods generally satisfy basic aquaculture requirements. However, most feeds used in crayfish aquaculture primarily consist of fish meal, soybean meal, and corn as the main raw materials, leading to high material costs and increased consumption expenses during the aquaculture process. Therefore, it is imperative to develop a feed for crayfish aquaculture and a corresponding aquaculture method to address this issue. Summary of the Invention The objective of the present invention is to provide a feed for crayfish aquaculture and a method for crayfish aquaculture, aimed at addressing the challenges outlined in the background technology. To achieve the aforementioned objectives, this invention proposes the following technical solution: a feed for crayfish aquaculture, which comprises the following components: fish meal, insect protein, soy protein isolate, cornmeal, wheat bran, spirulina powder, compound vitamin and mineral premix, probiotics, enzyme preparations, natural flavoring agents, sodium alginate, and kitchen waste supplement. The weight proportions of each component are as follows: 1015 parts fish meal, 810 parts insect protein, 810 parts soy protein isolate, 2025 parts cornmeal, 1518 parts wheat bran, 24 parts spirulina powder, 35 parts compound vitamin and mineral premix, 12 parts probiotics, 12 parts enzyme preparations, 12 parts natural flavoring agents, 12 parts sodium alginate, and 1518 parts kitchen waste supplement. As an additional technical solution of the present invention, the kitchen waste supplement is formulated from a mixture of vegetable leaves, fruit peels, rice, noodles, and bread crumbs. The preparation process for this supplement involves several key steps: lnitially, the collected kitchen waste is placed in a sterilization chamber to undergo thorough sterilization. Following sterilization, any kitchen waste containing excessive oil, salt, seasonings, coffee grounds, tea leaves, onions, garlic, or chili is removed, ensuring that no meat or fish remains in the mixture. Subsequently, the selected kitchen waste is thoroughly washed to eliminate soil, impurities, and inedible components. Next, the waste is crushed into a slurry and subjected to steaming and further sterilization. Finally, after steaming and sterilization, the mixture is allowed to cool to room temperature to yield the kitchen waste supplement. As an additional technical solution of the present invention, the insect protein is formulated from a blend of black soldier fly larvae powder, mealworm larvae powder, and silkworm pupae powder. The mixing ratio of these components is 3:1:1, respectively. A method for crayfish aquaculture, comprising the following steps: Step 1, pond preparation; Step 2, seedling stocking; Step 3, feed formulation and feeding; Step 4, water quality regulation; Step 5, disease prevention and control; Step 6, daily management; ln Step 1, a location near a water source with good water quality is selected for pond construction; the pond is excavated to a depth of 11.5 meters; the interior of the pond is pretreated, leaving a certain layer of silt at the bottom; an inlet and outlet are set up, and escape prevention nets are arranged at both the inlet and outlet. In Step 2, healthy crayfish seedlings are selected and evenly stocked into the prepared pond from Step 1 after transportation. In Step 3, the components are weighed according to the specified weight parts: 1015 parts fish meal, 810 parts insect protein, 810 parts soy protein isolate, 2025 parts cornmeal, 1518 parts wheat bran, 24 parts spirulina powder, 35 parts compound vitamin and mineral premix, 12 parts probiotics, 12 parts enzyme preparations, 12 parts natural flavoring agents, 12 parts sodium alginate, and 1518 parts kitchen waste supplement; the prepared raw materials are processed into a feed suitable for stocking and are regularly fed into the pond. In Step 4, water quality regulation is conducted based on the water condition in the pond; 10%20% of the pond water is changed weekly to maintain fresh water quality; potassium monopersulfate and other bottom-condition improvement agents are periodically used to enhance the sediment environment, and microbial agents such as photosynthetic bacteria and EM bacteria are added to improve water quality. ln Step 5, disease prevention and control are carried out by applying iodine preparations through spraying. In Step 6, feeding, water changes, and disinfection operations are recorded for management and traceability; the weight and length of crayfish are periodically measured to assess their growth conditions. As a further technical solution of the present invention, in Step 1, the inner walls of the pond are trimmed, the pond water is drained, and the pond is exposed to sunlight until cracks with a depth of more than 10 cm appear on the pond bottom. The pond bottom is then plowed to a depth of approximately 10 cm, followed by sundrying for about 10 days. Subsequently, the pond is disinfected by evenly spraying quicklime or bleaching powder into the pond. Water is introduced into the pond 57 days after disinfection. As a further technical solution of the present invention, in Step 2, crayfish seedlings are selected based on their health, strong vitality, and absence of visible diseases or injuries. The seedlings are uniform in size, with a length specification of 2 cm to 3 cm, and the transportation duration of the seedlings is limited to within 2 hours. As a further technical solution of the present invention, in Step 3, the process of preparing the feed for stocking comprises: first, separately adding fish meal, insect protein, soy protein isolate, cornmeal, wheat bran, spirulina powder, compound vitamin and mineral premix, probiotics, enzyme preparations, natural flavoring agents, sodium alginate, and kitchen waste supplement into a mixer. The mixture is then stirred at a low speed with a stirring speed of 3060 r / min for 1015 minutes. After that, clean water is added for mixing, with the water addition amounting to 30%40% of the total dry material weight. After mixing, the mixture is processed using a pellet machine for shaping. Upon completion of the shaping process, the feed is ready for stocking. The daily feeding amount is 3%5% of the crayfishs body weight, with feeding conducted twice a day, in the morning and evening. As a further technical solution of the present invention, in Step 4, water quality management ensures that the pH value of the pond water remains between 7.0 and 8.5. Aeration devices or microporous oxygenation equipment are used to increase dissolved oxygen levels, maintaining them above 5 mg / L. Regular monitoring is conducted to ensure that ammonia nitrogen levels remain below 0.2 mg / L and nitrite levels remain below 0.1 mg / L. As a further technical solution of the present invention, in Step 5, during disease prevention and control, iodine preparations are used as medication for treatment upon detection of branchial rot disease; oxytetracycline or florfenicol is used as medication for treatment upon detection of red leg disease. Compared with the existing technology, the beneficial effects of the present invention are as follows: By incorporating a kitchen waste supplement formulated from vegetable leaves, fruit peels, rice, noodles, and bread crumbs into the feed formulation as a primary raw material supplement, the invention enriches the feed with multiple nutrients while simultaneously reducing the consumption cost in the aquaculture process.
