Cartilage fish feed

Abstract

The invention provides cartilage fish feed, which is prepared from the following ingredients in parts by weight: 23 to 34 parts of peanut meal, 15 to 22 parts of bean meal, 4 to 7 parts of cuttlefish paste, 3 to 7 parts of Chinese herbal medicine additives, 8 to 16 parts of fish meal, 15 to 24 parts of algae compounds, 3 to 5 parts of potato starch, 1 to 4 parts of antioxidants, 10 to 20 parts of shrimp shell powder, 9 to 16 parts of wheat flour, 17 to 26 parts of sargassum pallidum, 0.6 to 1.2 parts of complex vitamin and 3 to 8 parts of sweet potato stems and leaves. The feed has the advantages that the nutrition proportioning ratio is reasonable; the requirements of the cartilage fish growth can be met; the immunological competence and the strain resistance capability of the cartilage fish can be effectively improved; the palatability is good; the stability in the water is good; the bait coefficient is low; the growth of the cartilage fish can be effectively promoted; the feed cost is low; the preparation method is simple; the water quality cannot be influenced after the feed throwing; no toxic and harmful substances are contained; green and environment-friendly effects are achieved.

Description

technical field [0001] The invention relates to a feed, in particular to a cartilaginous fish feed. Background technique [0002] Chondrichthyes or Selachii is a general term for all fish, including sharks, rays, rays and chimaeras. Just before the gradual extinction of the placoderms in the Devonian, the bony and cartilaginous fishes arose, and although the cartilaginous fishes were successfully grouped together, the number of species (about 550) was still higher than that of the teleosts or modern bony fishes (about 20,000 species) much less. Cartilaginous fishes differ from bony fishes in many ways, most notably that cartilaginous fishes have a skeleton made of cartilage, with vertebrae that are partially ossified but lack true bone. Other features include: 5∼7 pairs of gill slits; shield-like scales covered with tooth-like structures on the skin; numerous teeth arranged in the mouth. Most cartilaginous fish live in seawater, but there are also some freshwater sharks. ...

Problems solved by technology

By adopting the above-mentioned formula and preparation process, the invention improves a high-efficiency and palatable artificial compound feed, which has high nutritional value, complete color, fragrance and less environmental pollution, and promotes the rapid, stable and healthy development of pollution-free seawater fish breeding , not only can meet the nutritional needs of fish growth, but also has the advantages of good stability in water, less environmental pollution, and environmental protection. Its preparation method is simple, suitable for mass production, and it is prepared into 1-2mm particles, which is convenient for fish to eat, but In actual breeding, fish that eat this feed may have reduced immunity and are prone to infection with germs, and the feed coefficient is high, which may cause problems that fish cannot be completely eaten and affect water quality.
