Artificial pellet feed for adult turbot

Abstract

The invention relates to artificial pellet feed for adult turbot. The artificial pellet feed is characterized by comprising white fish meal, red fish meal, whey protein, soybean protein concentrate, soybean meal hydrolysate small peptide, scallop powder, chicken meal, high protein flour, alpha-starch, L-alanyl-L-glutamine, choline chloride, sea fish oil, soybean lecithin, krill meal, ocean red yeast, photosynthetic bacteria, Schizochytrium limacinum powder, haematococcus pluvialis powder, multivitamins, composite mineral substances, Chinese herbal medicines and sodium alginate. According to the feed, a plurality of kinds of raw materials are added into the feed, so that the comprehensiveness of nutrition is guaranteed. During actual culture of the turbot, the pellet feed for the adult turbot has the advantages that the feed is good in feeding promoting performance, fishes like the feed, are full easily and do not fall ill easily, the survival rate is high, and the feed coefficient is low; the digestibility and the feed conversion ratio are high; the growth rate of the fishes is high, and the culture cycle is short.

Description

technical field [0001] The invention belongs to the technical field of fish feed, in particular to an artificial granular feed for turbot adult fish. Background technique [0002] Since the introduction of turbot into my country, it has set off the fourth wave of mariculture, and it has been cultivated on a large scale in my country's coastal areas for a while, especially in Shandong and Liaoning provinces. The cultivation of turbot has become the backbone of mariculture. It has made great contributions to promoting the increase of fishermen's income and driving the development of local economy. [0003] In the process of turbot breeding, although the industrialized recirculating aquaculture model using underground deep well water has been established, a large part of turbot farming producers, based on the convenience of obtaining materials and the consideration of immediate cost savings, do not use water during the breeding process. Mainly feed chilled miscellaneous fish. ...

AI Technical Summary

Problems solved by technology

In this way, although the feed cost seems to be reduced, from the perspective of the whole breeding process, not only did not reduce the cost, but also it is easy to introduce new pathogens, which brings a lot of risks to the culture of turbot

[0004] At present, feed has been used in the breeding process of turbot adult fish, but most of the low-quality feed has the problem of nutritional imbalance, while the price of imported high-quality feed is too high, and the cost performance is low, and the fisherman's farming benefits are low

In addition, during the breeding process of turbot adult fish, parasitic diseases such as shield ciliates occur frequently, the incidence of lymphocyst disease is high, and the albinism rate is high at the same time, all of which seriously affect the culture of turbot adult fish. The survival rate of different stages, especially the occurrence of lymphocystosis and albinism will affect the appearance of farmed adult fish and reduce the commercial value
