Abstract
The invention provides a shelling interphase crawfish feed. The shelling interphase crawfish feed is prepared from the following components: corn flour, sorghum flour, wheat middling, peanut powder, shell powder, algae powder, fish meal, calcium hydrogen phosphate, compound vitamin, mineral composites and a core additive, wherein the core additive is prepared from the following components: houttuynia cordata, astragalus root, eucalyptus robusta, radix achyranthis bidentatae, selfheal, garlic, green tea and licorice. The feed can provide basic nutrients for crayfishes in shelling interphase, the algae powder and the core additive are added in the feed to greatly reduce the mortality rate of the crawfishes, and the shelling interphase crawfish feed is high in security, wide in raw material source and low in price.
Description
Technical field
The present invention relates to a kind of cray feed, particularly a kind of shelling interval cray feed and preparation method thereof and application.
Background technology
Cray is the shellfish that survives in a kind of picture lobster in fresh water, and formal name used at school Procambius clarkii is also red crayfish or freshwater crayfish.Procambius clarkii is the widest Invasive Alien Species that distributes in shell-fish.Procambius clarkii because of its omnivorousness, fast growth, adaptablely in local environment, form absolute competitive advantage.Its scope of ingesting comprises pasture and water, algae, aquatic insect, spoil etc., and food is deficient also kills each other when scarce.Procambius clarkii has become Important Economic breed variety in China in recent years.
The growth cycle of cray is relatively short, and a cray, from producing son, hatching to maturation listing, probably only needs half a year.Yet the two large shortcomings of cray become the obstacle that lobster industry further develops: the one, dressing percentage is low; The 2nd, lobster moves on sludge underwater, and feeding habits are assorted again, often take animals and plants corpse as food, thus in body surface and alimentary canal dirt and bacterium more.
Scientific research proves, in cray body, content astaxanthin is positive correlation with its ability of resisting extraneous adverse circumstances, also just says that body content astaxanthin is higher, and its ability of resisting extraneous adverse circumstances is just stronger.In purplish red color cray human body, the content of natural astaxanthin is the several times of prawn.So, wine-colored cray can be in dirty mud survival and reproduction, and in clear water body, be difficult for survival.Because cray self cannot produce astaxanthin, being mainly to pass through food chain--edible microalgae etc. gets astaxanthin, and constantly accumulates and produce superpower oxidation resistance in vivo.Astaxanthin can effectively strengthen ability and the raising fertility of the opposing adverse circumstances of cray.So astaxanthin is the strong guarantee of cray indomitable vitality like this, when lacking in these environment that contain the micro-algae of astaxanthin, cray is instead difficult to survive.Yet due to reasons such as the simple and easy muddiness of pond water, water pollution, the not enough mycotic infections of illumination, cray also can produce various diseases, such as black gill disease, soft-shell disease, tail etc.Existing artificial fecundation method is placed in In water by cray conventionally, has guaranteed the spatter property of cray, yet but causes the cray death rate higher.
The growth of cray realizes by shell.Shell is the important symbol of cray growth.Cray is the same with other crustaceans, and the crust that must slough off body surface just can complete its mutability growth.According to the movable and situation of ingesting of cray, its moulting cycle can be divided into intermolt, proecdysis, ecdysis and postmolt four-stage.The interval that shells is that cray is the stage of growth accumulation nutriment, ingests vigorous this shrimp of this one-phase, and crust is hardening gradually; Shell stops to starting shell early stage from cray stops ingesting, and this one-phase is that cray is that shell is prepared.Cray stops ingesting, and the calcium in crust shifts to the calcium stone in body, and in body, calcium stone becomes large, crust attenuation, deliquescing, and separated with inner cortex layer.The shell phase is to lie on one's side till shell starts completely to slough off to crust from cray, these about a few minutes to tens of duration in stage minute not etc., we observe mostly at 5-10 minutes, overlong time cray is easily dead.The shell later stage is to starting to ingest, to stop from cray shell, and this stage is the process that the crust of cray is developed to crust by cortical layer.Moisture enters in body from cortex, body gains, increase; In body, the calcium of calcium stone shifts to cortical layer, and cortical layer hardening, thickening, become crust, and in body, calcium stone finally becomes very little.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of interval feed of using of cray that is suitable for shelling, can greatly reduce the shell phase cray death rate.
