This invention relates to the field of fish feed technology, specifically to a precise nutritional formulation method for low-fishmeal largemouth bass compound feed. It includes the following steps: S1, extruding and puffing the low-fishmeal base raw material, controlling a specific extrusion temperature and instantaneous pressure drop at the discharge port to obtain an extruded granular skeleton with a connected microporous structure; S2, adding an aqueous phase containing water-soluble gut-protecting factors to an oil phase containing a fat-soluble attractant and a low HLB value emulsifier, and preparing a W / O type microemulsion through high-speed homogenization and encapsulation; S3, placing the puffed skeleton in a vacuum spraying machine under negative pressure, spraying the microemulsion, and then gradually depressurizing in a stepwise manner to achieve deep anchoring of the microemulsion. This invention utilizes the fat-soluble oil phase to form a natural waterproof barrier to prevent water loss, and competitive adsorption under the action of high concentrations of bile acids in the largemouth bass intestine to achieve targeted demulsification and release, significantly improving hepatointestinal health and survival rate.

Texas rig fishing is an effective method of fishing, particularly suited for bass, that allows anglers to fish in bodies of water with significant submerged vegetation or other obstacles that may make maneuvering a traditional fishing line and lure difficult. For these applications, a weight is added to the line near the hook to improve the ability for the angler to control the depth of the lure and the maneuverability of the fishing lure. These weights are called bullets. The present invention relates to an improved bullet design that reduces the risk of the fishing lure being entangled by underwater vegetation or other obstacles, protects the soft plastic lure from wear, and prevents breakage throughout the entire fishing process while also removing the need to peg the bullet or use a bobber stop.

This invention relates to the field of aquatic feed technology, specifically to a largemouth bass and black soldier fly oil feed and its preparation method, which is made by mixing basic components, oil source components, additives and functional components. The basic components include the following ingredients in parts by weight: 30-40% fish meal, 3-8% soybean meal, 15-25% chicken meal, 3-8% corn gluten meal, 10-15% cottonseed protein, 4-10% wheat flour and 2-6% cassava starch. The oil source components include the following ingredients in parts by weight: 1-2% soybean oil, 2-5% black soldier fly larvae oil and 1-3% Schizochytrium oil. The functional components include the following ingredients in parts by weight: 0.5-1.5% premix, 0.5-1.0% choline chloride, 0.05-0.2% vitamin C, 0.1-1.0% DL-methionine and 0.05-0.2% ethoxyquin. The fish oil-free compound oil feed of the present invention can not only replace fish oil, but also supplement n-3 LC-UFA through Schizochytrium oil, which can improve the problem of insufficient deposition of unsaturated fatty acids in muscle and deterioration of muscle fiber structure caused by the use of black soldier fly larvae oil alone, thus improving both economic benefits and meat quality.

This utility model relates to the field of bass farming technology, specifically a bass farming box with an automatic cleaning function, comprising: a tiered farming component and a cleaning component. The tiered farming component consists of a box body, limiting blocks, tiered plates, and a filter screen. The limiting blocks are installed on the inner wall of the box body. This bass farming box with automatic cleaning function, through the arrangement of the box body, limiting blocks, tiered plates, and filter screen, allows for tiered farming of bass by fixing the limiting blocks to the box body and connecting the tiered plates. The equidistant arrangement of the tiered plates facilitates the flow of water into all parts of the box, allowing bass of different sizes to be farmed in different water layers. For example, smaller fry can be farmed in the upper layer, while larger adult fish can be farmed in the middle or bottom layer. This fully utilizes the vertical space of the farming water body, increasing the farming density per unit water volume. Tiered farming improves space utilization and increases farming density.

The present application belongs to the field of fish molecular immunology, and particularly relates to an oral vaccine containing a largemouth bass iridovirus ATPase and a preparation method thereof. B. subtilis The spores of the WB600 strain are antigen delivery carriers, the spore coat protein C (CotC) is used as an anchor protein, and the key protein of the largemouth bass iridovirus is fused with the ATPase gene and CotC the gene to construct a recombinant spore surface display system, so that the ATPase antigen is stably displayed on the spore surface, and an oral vaccine is prepared. The vaccine can tolerate the gastrointestinal environment after being orally administered to fish, and is accurately delivered to the gut-associated lymphoid tissue to stimulate the immunity of the fish, so that the prevention and control of the largemouth bass iridovirus is finally achieved.
