Embodiment 1a

[0034] A method for preparing fish feed, comprising the following steps:

[0035] Step1, fish paste preparation

[0036] Step1.1, material selection: pass all kinds of small miscellaneous fish caught from the sea through a sieve with a mesh diameter of 10cm, and select marine fish with a fish shape of no more than 10cm through the sieve as raw fish. In this embodiment, , the miscellaneous fish salvaged include matchmaker fish, red golden drum fish, dragon head fish, big head dogfish, golden eye thick, snake mackerel and money fish;

[0037] Step1.2, heating: Weigh 50kg of raw fish into the boiler, add 20kg of water while stirring and cook, heat to 85°C, and keep warm for 15 minutes;

[0038] Step1.3, crushing: adjust the temperature to 80°C, filter through a 10mm sieve under heat preservation, take the raw fish dregs and crush the raw fish through ultrasonic crushing until the broken particles are below 10mm and mix with the filtrate to obtain fish meal raw materials;

[003...

Embodiment 1b

[0055] The preparation method of Example 1b is roughly the same, the only difference being that Step1.2 is heated to 95°C.

Embodiment 1c

[0057] The preparation method of Example 1c is roughly the same, the only difference being that Step1.2 is heated to 90°C.

Abstract

The invention relates to feed production and in particular discloses fish feed and a preparation method thereof, aiming at solving the problems that the food calling rate of part of feed on fishes isnot high so that the growth of the fishes is too slow and the culture cost is also improved. According to the technical scheme, the fish feed is prepared from the following raw materials in parts by mass through mixing: 15 to 20 parts of minced fish, 15 to 20 parts of wheat bran, 15 to 20 parts of shrimp shell dreg, 15 to 20 parts of corn starch, 5 to 10 parts of silkworm pupa powder, 1 to 3 partsof eel blood, 1 to 3 parts of yolk liquid, 1 to 3 parts of honey, 0.1 to 0.5 part of fish bone peptide and 0.1 to 0.5 part of table salt. The fish feed provided by the invention has a relatively highfood calling rate; fish meal is produced by adopting marine small fishes; the fish bone peptide is extracted by utilizing leftovers for producing the fish meal, so that the utilization rate of the raw materials is improved and wastes are reduced.

Description

technical field [0001] The invention relates to feed production, in particular to a fish feed and a preparation method thereof. Background technique [0002] Fish feed, as the name suggests, is feed for fish. Its main components are protein, fat, vitamins and minerals. For example, the patent publication No. CN103404733B discloses a method for making ornamental fish feed, which is prepared from 9 kinds of raw materials: wheat germ, fish meal, chicken liver powder, silkworm chrysalis powder, whole egg powder, dried shrimp powder, dehydrated spinach, red Koji powder and soybean protein peptide. In addition to essential nutrients such as protein, sugar, fat, inorganic salts, vitamins, and cellulose, the feed also contains ingredients such as monascus pigment, various digestive enzymes, and protein peptides. It can increase the color of the fish body, improve the ornamental value, reduce the number of harmful microorganisms in the fish intestinal tract, improve the level of me...
