The invention discloses a squaliobarbus curriculus breeding and breeding method based on aquaculture. According to the method, slow flow domestication is started from the fry stage, the fries are made to adapt to the dynamic water environment from small, the physique is obviously enhanced, the fries are not prone to being infected with diseases during adult fish culture, and the trouble and cost of medication are reduced. In addition, through the feed transition domestication in the S3, the palatability of the fries eating the compound feed in the later stage is better, the growth speed is more uniform, the subsequently screened water-infused fishes are neat in specification, the water-infused fishes can more quickly adapt to fasting and water flow environments during water infusing, the weight-reducing and fishy smell-removing effects are more stable, the meat quality is compact and elastic, the mud fishy smell basically disappears, and the quality and the appearance of the fishes are directly improved; a cycle is formed from parent fish selective culture to sales feedback, the parent fish breeding direction and the adult fish culture density can be adjusted in time according to the requirements of the market end, the unsalable risk caused by blind culture is avoided, and the income of farmers is guaranteed.

This utility model relates to the technical field of raw food refrigeration and preservation boxes, and more particularly to a low-temperature refrigeration and preservation box for raw red-eyed trout products. The box includes a preservation box with a low-temperature shelf at the bottom, and placement shelves stacked on top of the low-temperature shelf. Symmetrical guide grooves are formed on the inner walls of both sides of the preservation box. Guide strips adapted to the guide grooves are installed on both sides of the low-temperature shelf and the placement shelves. A flow channel is formed from the center to both sides on the bottom wall of the placement shelves, and a collection channel corresponding to the flow channel is formed on the inner walls of both sides of the preservation box. A refrigerant is placed inside the low-temperature shelf, and a temperature equalization mechanism is provided on the low-temperature shelf to transfer the low temperature from the bottom layer to the top layer. When the refrigerant cools and produces condensation, the condensation flows through the guide grooves into the collection channel and then to the bottom of the preservation box. The condensation is absorbed by highly absorbent cotton, thus preventing condensation from accumulating in the placement shelves and causing the raw fish to spoil.

The utility model discloses a tilapia mossambica hotbed type overwintering device, which relates to the technical field of aquaculture devices and comprises a warmer and a hotbed. The heater is used for providing hot water into the hotbed; the hotbed is arranged at the bottom of the overwintering pond. The tilapia mossambica hotbed type overwintering device is easy to manufacture and convenient to operate, hot water is provided for the hotbed through the heater, only the water temperature in the hotbed is increased, tilapia mossambica overwinter on the hotbed, hot water in the hotbed does not exchange with pond water in the overwintering pond, and energy is saved by more than 40%.

The present utility model relates to a process for producing feed for saline-tolerant tilapia (Oreochromis niloticus) fry and fingerlings using a β-cyclodextrin-encapsulated lemongrass essential oil-based feed additive. The utility model addresses the technical problem of incorporating volatile antimicrobial essential oils into aquaculture feed while maintaining their stability, uniform distribution, and compatibility with conventional feed pellet manufacturing. The process comprises preparing a dry feed mixture, combining the encapsulated feed additive with a binding agent, gradually incorporating the resulting liquid mixture into the dry feed mixture, pelletizing, drying, and storing the feed pellets. The process produces nutritionally balanced feed containing uniformly distributed encapsulated lemongrass essential oil with improved stability and handling characteristics. The disclosed process is particularly useful for producing feed for hatchery and nursery culture of saline-tolerant tilapia fry and fingerlings as a practical alternative to conventional antibiotic-based feed production.

The application discloses a tilapia Npy antibacterial peptide, a coding sequence, and a use and a preparation method thereof, and relates to the following technical scheme: based on a multi-omics method, an antibacterial peptide precursor gene sequence is screened and recognized from a tilapia multi-omics data set based on biological big data, and then the tilapia Npy antibacterial peptide amino acid sequence is obtained through translation design, as shown in SEQ ID NO: 3; through activity simulation prediction and in-vitro experiment verification, the tilapia Npy antibacterial peptide shows inhibitory activity to gram-positive streptococcus agalactiae, staphylococcus aureus and gram-negative escherichia coli, especially to streptococcus agalactiae and staphylococcus aureus, and shows good antibacterial effect at a low concentration (2.5 μmol / L), and can be used for preparing antibacterial products, including preparation of an antibacterial agent, preparation of a medicine or preparation of an additive, and has good practical value and social ecological benefits.

This invention discloses a fermented feed formula for Sudan fish and its preparation method. The fermented feed for Sudan fish first ferments fermentable raw materials such as wet brewer's grains, peanut meal, and grade 2 soybean meal to form fermented material. Then, the fermented material, soybean oil, choline chloride, lysine, fish compound vitamin premix, and fish compound trace element premix are mixed to obtain the fermented feed. This method prevents the easily fermentable raw materials such as soybean oil, amino acids, and premix from being easily destroyed and rendered ineffective by microbial treatment. The main material used in this fermented feed is wet brewer's grains, a byproduct of beer production, which reduces the overall production cost. Furthermore, no additional water is needed when preparing the fermentation base, saving time and labor. Compared with ordinary compound feed, the fermented feed has a better effect on the weight gain of Sudan fish, promotes intestinal function, and improves the digestibility and absorption rate of feed.

The invention discloses a tilapia mossambica prevention and control method combining perch-elopichthys bambusa sequential putting in an artificial wetland. The tilapia mossambica prevention and control method comprises two aspects of sequential prevention and control of grazing feeding fish and water quality regulation and control of a vertical subsurface flow artificial wetland. Wherein the sequential prevention and control of the grazing fish comprises four stages of early-stage physical group pressing, weever grazing, ground cage monitoring and threshold value judgment and elopichthys bambusa supplementary control, and the tilapia mossambica groups which can enter sexual maturity in the current season are pressed to a preset ecological safety threshold value. The water quality regulation of the vertical subsurface flow constructed wetland is that a vertical subsurface flow upstream constructed wetland is built in a water area bank zone, part of water is pumped into a composite functional filler layer, and the water quality condition is improved by combining plants, hydraulic operation, linkage detection and regulation, so that the grazing-feeding fishes keep higher survival rate and ingestion intensity, and the survival rate of the grazing-feeding fishes is increased. And controlling the total nitrogen and phosphorus within a preset range while controlling the number of 5-12cm specification sections of the tilapia mossambica. And finally, forming an annual control file according to indexes involved in the process, and providing a basis for fish putting and optimization in the next year.
