Embodiment 1

[0019] Preparation method: First, the Norwegian fish meal, krill meal, fat powder and dehydrated spinach leaves are fully pulverized with a high-speed pulverizer respectively; after crushing, the Norwegian fish meal and krill meal are sterilized in an autoclave at 60°C. After the above components are screened with a 150-mesh sieve, fat powder and dehydrated spinach leaf powder are added and mixed evenly. According to the volume ratio of feed components: distilled water = 3:1, measure distilled water, first add spirulina powder and squid paste into distilled water and stir well, then add other components, fully mix evenly, and press into a thickness of 0.3cm Thin slices; use the characteristics of spirulina powder to produce adhesion when it meets water, without adding other adhesives. Put the flakes into a fume hood and let them air dry at natural temperature. The prepared dry flake feed is sealed and stored in a refrigerator in a fresh-keeping mode.

Abstract

The present invention discloses a special compound feed for pseudacanthicus, a preparation method and a using method thereof, and belongs to the field of aquaculture feed. The preparation method of the special compound feed is characterized in that Norwegian fish meal, krill meal, spirulina powder, fatty powder, dehydrated spinach leaves, squid paste, and compound vitamins are taken as structural components, additive components and adhesive components; and after the structural components, the additive components and the adhesive components are subjected to crushing and screening, partial sterilizing and processing at a low temperature. Compared with a current common ornamental fish feed, the feed prepared according to the method has characteristics that the feed is convenient for demersal pseudacanthicus to scrap and eat, does not add any other feed adhesives, meets the nutritional requirement of the pseudacanthicus for corrupted animal foodstuff as main food and plat fiber as complemental food, meets the requirement of the pseudacanthicus for fat, and has a good attractant effect. The technical process in the present invention adopts a preparation method that partial components are sterilized and the processing process is conducted at room temperature, so that the nutritional loss caused by high temperature sterilization and puffing process is prevented, and the reduction of attractant effect caused by heating is prevented.

Description

technical field [0001] This patent refers to the production and use of a new type of special compound feed for scraping fish as a technical field. technical background [0002] Pseudocanthicus (Pseudacanthicus) is a popular high-end ornamental fish in the Amazon Basin of South America, commonly known as tank fish. The fish has a lower mouth and lives on the bottom. It relies on the horny spines in the mouth and eats by scraping and licking repeatedly. It is very different from the way of swallowing and the food and nutrition needed by ordinary swimming fish. The fish is large in size, high in price, and has a special feeding method and feeding habits. It is necessary to develop a compound feed with good palatability, food attraction and comprehensive nutrition to ensure its daily healthy feeding. The body surface of the pseudo spiny catfish is layered with strong and hard scales (called muscle teeth in fish science), which shows that it has a certain demand for calcium. Th...
