Problems solved by technology

Therefore, there is a gap between the feeding habits of turbot and the pelletizing process requirements of extruded materials.
As the traditional turbot bait, chilled fish has the characteristics of good food attractant and fast growth rate, but its bait coefficient is high and it is easy to pollute the water quality, especially for turbot that is mainly cultured in indoor cement ponds. The pollution of water quality results in a large amount of water exchange, many diseases and high costs
[0003] As early as many years ago, some pioneers tried to use soft pellet feed to raise turbot. However, due to the phased understanding of turbot nutrition, especially the large defects in the control of total sugar in early turbot soft pellets, made earlier explorations unsuccessful

[0023] The turbot compound feed described in this embodiment comprises chilled fresh fish and concentrated feed, and the mass ratio of said chilled fresh fish and concentrated feed is 3:7, wherein the concentrated feed contains the following components in parts by weight:

[0024] 40 parts of imported Peruvian fish meal, 8 parts of shrimp shell powder, 5 parts of chicken meal, 17 parts of gluten powder, 5 parts of alpha starch, 10 parts of fermented soybean meal, 4 parts of puffed soybean, 9 parts of brewer's yeast, 3 parts of blood meal, 2 parts of soybean oil , 1 part of phospholipid oil, 5 parts of squid paste, 1 part of calcium dihydrogen phosphate, and 5 parts of premixed feed.

[0025] The preparation method of the described turbot compound feed of this implementation comprises the following steps:

[0026] (1) making minced meat from the chilled fish;

[0027] (2) the concentrated material is crossed through a 90 mesh sieve;

[0028] (3) Put the minced meat obtained i...

Embodiment 2

[0030] The turbot compound feed described in this embodiment comprises chilled fresh fish and concentrated feed, and the mass ratio of said chilled fresh fish and concentrated feed is 7:3, wherein the concentrated feed contains the following components in parts by weight:

[0031] 30 parts of imported Peruvian fish meal, 5 parts of shrimp shell powder, 6 parts of chicken meal, 15 parts of gluten powder, 5 parts of alpha starch, 12 parts of fermented soybean meal, 5 parts of puffed soybean, 10 parts of brewer's yeast, 1 part of blood meal, 1 part of soybean oil , 1 part of phospholipid oil, 4 parts of squid paste, 1 part of calcium dihydrogen phosphate, and 5 parts of premixed feed.

[0032] The preparation method of the turbot compound feed described in this implementation is the same as in Example 1.

Embodiment 3

[0034] The turbot compound feed described in this embodiment comprises chilled fresh fish and concentrated feed, and the mass ratio of said chilled fresh fish and concentrated feed is 1:1, wherein the concentrated feed contains the following components in parts by weight:

[0035] 45 parts of imported Peruvian fish meal, 6 parts of shrimp shell powder, 8 parts of chicken meal, 12 parts of gluten powder, 8 parts of alpha starch, 10 parts of fermented soybean meal, 1 part of puffed soybean, 8 parts of brewer's yeast, 5 parts of blood meal, 1 part of soybean oil , 1 part of phospholipid oil, 4 parts of squid paste, 1 part of calcium dihydrogen phosphate, and 5 parts of premixed feed.

[0036] The preparation method of the turbot compound feed described in this implementation is the same as in Example 1.

Abstract

The present invention discloses a compound feed for scophthalmus maximus and a preparation method thereof. The compound feed comprises iced fresh fish and concentrated materials. The mass ratio of the iced fresh fish and the concentrated materials is (3-7):(3-7). The provided compound feed for the scophthalmus maximus has the advantages of being comprehensive in nutrition, small in feeding amount and good in attractant of the iced fresh fish.

Description

technical field [0001] The invention relates to a compound feed and a preparation method thereof, in particular to a turbot compound feed and a preparation method thereof. Background technique [0002] Turbot belongs to the class Osteophytes, and it is also called European flounder. The place of origin is the European Atlantic sea area, and it is one of the world-recognized high-quality flounder. In 1992, the Yellow Sea Fisheries Research Institute of China introduced it from the UK, and after the large-scale production of seedlings was successful in 1999, my country began to promote aquaculture in the northern coast and became an important marine aquaculture object. Up to now, it has developed to Liaoning, Shandong, Hebei, Jiangsu and other regions, with an annual output of nearly 45,000 tons. Known and loved by more and more Chinese people. But progress on turbot bait has been modest. About 70% of turbot bait is still chilled fish. Although extruded feed has made some...
