Problems solved by technology

[0002] Filter-feeding fish feed on phytoplankton, zooplankton and organic debris in the water by filtering; filter-feeding fish have been mainly cultured naturally for a long time, and their feed is often animal manure or organic fertilizer or inorganic Pond culture yield is low, and the pond water is difficult to control, often resulting in hypoxia, pond flooding, and death; the fish's physique is poor, the meat quality is poor, and there is peculiar smell, which affects the commercial value of fish; due to the serious lack of feed sources in cage culture , forced to expand the breeding area and increase investment, resulting in a long breeding cycle. When breeding filter-feeding fish species with a tail weight of 150-500 grams, it often takes more than 3-5 years to be raised on the market. Therefore, the breeding benefits are low and the risk increases. Big

Embodiment 1

[0016] Example 1, filter-feeding fish feed is mainly made of energy feed materials, plant protein feed materials, animal protein feed materials, mineral feed materials, etc., in powder form, and the diameter of the powder particles is smaller than 5mm, the formula ratio is: (in parts by weight) energy feed materials 0-30, vegetable protein feed materials 30-60, animal protein feed materials 10-30, and mineral feed materials-10;

Embodiment 2

[0017] In Example 2, the present invention is made from the following raw materials, which are in powder form, and the diameter of the powder particles is less than 5mm. The formula ratio is: (by weight) 15-25 sub-flour, 10-40 soybean meal, and 4-fish meal 20. Silkworm pupa meal 2~10, meat and bone meal 2~10, feed yeast 2~4, cotton meal 2~20, peanut meal 2~10, rapeseed meal 2~20, calcium hydrogen phosphate 1-2, fish premix 1~4;

Embodiment 3

[0018] In Example 3, the present invention is made from the following raw materials, which are in powder form, and the diameter of the powder particles is less than 5mm. The formula ratio is: (in parts by weight) 20-30 sub-flour, 10-30 soybean meal, and 2~ 10. Cotton meal 10-20, peanut meal 10-15, rapeseed meal 10-20, dicalcium phosphate 1-2, fish premix 1-4;

Abstract

A feed for filter fish is a granular feed prepared from energy-type raw material (0-100 wt. portions), vegetable protein (0-100), animal protein (0-100) and minerals (0-20). The method for raising the said filter fish with the said feed features that the feed is loaded in bags and then suspended in the water. It can be dispersed in the water at moderate speed, so accelerating growth of fish.

Description

Technical field: [0001] The invention belongs to the technical field of feed, and specifically relates to a filter-feeding fish feed and a breeding method. Background technique: [0002] Filter-feeding fish use filtration to feed on phytoplankton, zooplankton and organic debris in the water body; filter-feeding fish have long been naturally farmed, and their feed is often animal manure or organic fertilizer or inorganic Fertilizer; pond aquaculture production is low, the pond water is difficult to control, often resulting in hypoxia, flooding, and death; fish have poor physical fitness, poor meat quality, and peculiar smell, which affects the commodity value of fish; cage aquaculture is seriously lack of feed sources in the water body Forcing the expansion of aquaculture area and investment, resulting in a long breeding cycle. When breeding filter-feeding fingerlings with a tail weight of 150 to 500 grams, it often takes more than 3 to 5 years to be marketed. Therefore, breeding ...
