In this paper, through the analysis of the southern Jiangsu area Megalobramaamblycephala pond aquaculture growth and benefit, to explore a set of relativelyreasonable Megalobrama amblycephala pond aquaculture, obtain better economic benefitof breeding with period。Concentrated in the southern Jiangsu Megalobrama amblycephala aquaculture area of7randomly selected blunt snout bream cultivation pond for data analysis,。Analysis of4aspects for each bream ponds: aquaculture fish stocking, harvest and growth rate,economic value added benefit of farmed fish, forage breeding efficiency and input andoutput the economic benefits of the pond. The results show that: Although it is different ofthe fish pattern for the7ponds, blunt snout bream can obtain the value of the best, andgrass carp can obtain the value of the worst. We can see that: To blunt snout bream asmajor species of pond, blunt snout bream can bring the best added value and benefits, butnot grass carp. So when we feed the blunt snout bream as the main cultured species, wecan put fingerling with some carp, as the filter-feeding fish, bighead and silver carp areindispensable. This model can bring pretty good added value and benefits.And we researchthe7blunt snout bream ponds as a whole, we are trying to find out the effect of the pondoverall input-output and the speed of growth, fingerling culture mode for the growth andbreeding efficiency of breeding; the effect of stocking size and stocking density of bluntsnout bream as the main cultured species for the growth and breeding efficiency ofbreeding; Analysis of different species of input and output and growth rate and analysis ofthe overall cost of breeding and economic benefits. The results show that: The density istoo high or too low can not bring the best benefit growth for blunt snout bream as the maincultured species, the better growth effect is achieved when the breeding density controlwithin the range of115-120kg/666.7㎡, the corresponding blunt snout bream stockingsize control in (41.67-50) g/is relatively reasonable. The overall investment of the pond,breeding fish feed has become the main form of farming costs, accounted for the total input 72,31%, secondly, The investment accounted for about10%of fingerling. Thus it can beseen: In blunt snout bream breeding process, to obtain good economic benefits, in additionto the focus on fingerling stocking collocation mode, feed quality right choice of feedingfish is also an important factor to obtain essential good economic benefit.
