Method for cultivating rotifers by using dried yeast and Antarctic krill meal

The invention relates to a method for rapidly producing freshwater wheel animalcule and resting eggs of the freshwater wheel animalcule by utilizing a leaching solution of freshwater fishes. According to the method, the leaching solution of fishes is utilized for rapidly producing the freshwater water wheel animalcule and resting eggs of the freshwater wheel animalcule; the leaching solution of the fishes is filtrate obtained after freshwater fish bodies or internal organ wastes are naturally decomposed and degraded by aerated tap water. The leaching solution of the fishes is artificially prepared by adopting the aerated tap water under natural light illumination and room temperature; bait micro-algae and a wheel animalcule solution universal culture medium are prepared according to the ratio of the leaching solution, and the wheel animalcule take freshwater chlorella as a food. The freshwater wheel animalcule and the resting eggs thereof are rapidly produced by adopting a continuous air inflation and continuous illumination method. The method can be used for conveniently, rapidly and economically collecting lots freshwater wheel animalcule and the resting eggs of the wheel animalcule for fish initial feeding baits and other researches. The method is applicable to lab researches and production of biological baits for initial feeding of aquatic product products. The method is simple, convenient, rapid, economical and convenient to use.

Simple method for purifying rotifers in batch

The utility model discloses a breed aquatics pond surface blowdown and device of administering blue alga oxygenation simultaneously. Taking to set up the drain pipe perpendicularly in blowdown department of pond central authorities and inserting the outlet, the drain pipe upper end is through 90 degrees return bends of bearing connection, and the return bend is one section one -way trompil blow off pipe of transverse connection again, passes through an articulate table flotation in the oxygen -increasing machine of the surface of water at the end of blow off pipe. The utility model discloses owing to be fixed with a riser and waterproof in pond central authorities, violently the pipe is upward porose, and half submergence is in the top layer aquatic, so behind the blow off pipe outside extracting, only surperficial water passes through the tube hole and flows out, in addition violently manages and is rotating, just all discharges the filth on surface in the suction pipe. And because the blue alga is generally concentrated on the top layer of water, the utility model discloses discharge top layer water that can be single -minded, the blue alga is administered to the blue alga of just can discharging simultaneously. Because the oxygen -increasing machine is unset, start the oxygen -increasing machine and promote tub rotatoryly around the central canal along the surface of water promptly, rotatory oxygen -increasing machine and the surperficial water of the pipe of drive stirring just can reach the purpose of oxygenation.

The invention discloses an application of viscous fluid animal first feed for fish fries, and belongs to the technical field of biological breeding. The invention breaks through the inherent concept of the traditional first feed, and changes the constant granular shape into plasticity, and the first feed is transformed into cenobium with large grain size from rotifers, protozoa and shellfish larvae as the suitable first feed. The main ingredient of the viscous fluid animal first feed for the fish fries is rhodopseudomonas capsulate. The invention has the beneficial effects that the economic benefit is obvious; by means of applying the viscous fluid animal first feed for the fish fries as the first feed at the initial stage of breeding of seawater fish fries, the survival rate of the seawater fish fries at the initial stage of breeding is greatly increased; the first feed can be produced on scale so as to provide reliable feed sources for the breeding of the fish fries; and the viscous fluid animal first feed has the advantages of simpleness for breeding as well as storage and transportation, wide circulation range, low cost, stable performance, high cost performance and simpleness for promotion, and plays a very important role in breeding the fish fries.
