Description

Application of the euphausia superba powder in terms of Pseudorabora parva opening material is prepared
Technical field
The invention belongs to technical field of aquaculture.Pseudorabora parva opening material is being prepared more particularly, to euphausia superba powder The application of aspect.
Background technology
Pseudorabora parva be it is a kind of be important fancy fishes, florid cheeks, towering forehead signifies that many good fortune are long-lived, both sides " the ink speck squama " come in every shape more has the magical effect for urging wealth in art of geomantic omen.Pseudorabora parva is gorgeous except magnificent and mighty king's imposing manner Beyond brilliant moving color, the lovely profile for having hommization, most make numerous fans get drunk wherein be difficult to extricate oneself a bit, just It is them and raises the complex bred of sentiments between master:Arhat is very violent to other fish, but people pole is had sagacity.As long as owner comes In front of fish jar, arhat will swim cheek by jowl, be played with raising main play.
The cultivation cultivation of Pseudorabora parva fry has considerable economic benefit, and the opening of fry has great importance, right There is vital influence in the survival rate and rate of body weight gain of fry.Before opening, fry is affected by environment very big, and the death rate is very It is high;After opening, every Survival outcome substantially increases, so, in this kind of fish breeding production, it is crucial that fry opening also serves as one Control point, attracts attention.At present, the related feed research of Pseudorabora parva focuses mostly in hyperchromic, and is studied on special opening material It is very few.More using natural bait as opening material, there is that cost is high, easy polluted water, quality is unstable, is easily introduced parasite, bacterium The shortcomings of with the cause of disease such as virus.
Research and report in the prior art for aquatic product dedicated openings material is few, the feed of basic simply reference adult fish The nutritional need of juvenile fish is formulated and combined, more fine and high-quality raw material is selected, so that opening material is made.And for different fishes The research of the opening rule and preference of seedling etc. is very related to less.Therefore, the effect of prepared opening material is barely satisfactory, it is impossible to well Meet demand and the requirement of aquaculture industry.
In addition, euphausia superba powder has preferably effect in terms of aquatic feeds, it is that one kind has before larger exploitation The high-quality resource of scape.But euphausia superba powder Oil repellent is high, this is also the problem of its maximum is most difficult to overcome place, and limiting it should With.
The content of the invention
The technical problem to be solved in the present invention is to overcome the research of existing Pseudorabora parva fry opening technology not enough and the South Pole The problem of krill meal Oil repellent is high, is prepared for the euphausia superba powder that Oil repellent is less than 1mg/kg, and then a kind of Pseudorabora parva of optimization Dedicated openings material, is researched and developed for the growth of Pseudorabora parva seedling opening stage, physiology digestion characteristics and Preference of ingesting, special to open Mouth material pin has good food calling performance to Pseudorabora parva seedling, can fully meet the nutritional need of its phase that is open, improves immune Power, anti-stress ability and survival rate;And with preferable hyperchromic effect.
It is an object of the invention to provide application of the euphausia superba powder in terms of Pseudorabora parva opening material is prepared, especially low fluorine south Pole krill meal.
