The First Fishery Production Squad of the He-luo Commune,in the culture of edible fishes,has for quite some time been making full use of its rich reso- urces of natural food and plentiful clear-water supply,and paying particular attention to"stocking fish","mixed culture","dense stocking"and"good ma- nagement",and got steady high yield.The important experiences are as foll- ows: 1.Individual fishes at the time of stocking should be of pretty large sizes,e.g.,grass carps of 0.8～1.7 catty/tail and black carps of 1～3 catty/tail. 2.Taking into consideration the food available,ponds are chiefly stocked with grass and black carps.Silver and bighead carps,common carps,breams and crucian carps are to be mixed with the former. 3.Plentiful food,deep water,suitable pond size,mixed culture of some species of fish have made dense stocking possible,which contribute much to the increased yield. 4.Steady high yield can never be materialized without subjective initia- tive and enthusiasm.Careful stocking and good management are also keys to steady high yield. (1)early cleaning and early repairing of ponds benefit the growth of fish. (2)in feeding attention should be directed to"evenness,quality and sufficiency",i.e.,fishes are fed according to weather and climate,water colour and fish appetite. (3)sufficient feeding and suitable dense stocking may cause lack of oxygen and adversely affect growth or even cause death of fish.Through controlling of feeding,adding of fresh water to improve water quality and water colour, suffocation can be prevented. Some problems remain to be solved.(1)The present 4-year culture-cycle for black and grass carps,and 3-year culture-cycle for breams have to be shortened.(2)The gaps in yield between one pond and another have to be narrowed down.(3)The use of fertilizers and the planting of food crops should be promoted.(4)Technique in the culture of yearlings and 2-year olds should be improved.(5)The marketing size of silver and bighead carps should be increased.(6)Disease and high mortality of yearlings and the 2-year-olds of the grass and black carps are to be prevented.
