Comprehensive Utilization Techniques for Fish Fingerling Ponds During the Winter Fallow Period
Using Winter-Fallow Fingerling Ponds to Raise Marketable Fish Raising a crop of marketable fish in winter-fallow fingerling ponds can both increase production and help regulate the "summer shortage" in the aquatic product market. Because the rearing period is relatively short and temperatures are low, the following techniques should be adopted: 1. Stock early, that is, stock immediately after the fingerlings are concentrated in ponds, so as to make full use of the growing period. Based on a maximum water depth of 2 m, the usual stocking rate is 125-150 kg per mu. The usual stocking ratio is about 40% silver carp, about 10% bighead carp, about 30% grass carp and bream, and about 20% black carp and common carp. Stocked fish

Main-culture techniques for freshwater pomfret (piaractus brachypomus) in shallow ponds
Among existing ponds, shallow ponds still account for a very large proportion. Such ponds are shallow, lack matched drainage and irrigation systems, and some are formed by seasonal flooding; when traditional fish species are farmed in them, fish yields are low and returns are very poor. To explore ways to increase production, income and efficiency in such ponds, for two consecutive years from 1993 to 1994, we conducted a "trial of main-culture of freshwater pomfret in shallow ponds" in three ponds with a total area of 9.7 mu and a maximum water depth of 1 m. Without aeration facilities, satisfactory results were achieved: in 1994 the average yield per mu was 227 kg

Comprehensive Utilization Methods of Fish Fingerling Ponds During the Winter Fallow Period
Raising market-size fish: Using winter-fallow fingerling ponds to raise one season of market-size fish can both increase production and help ease the "summer shortage" in the aquatic product market. Because the rearing period is relatively short and temperatures are relatively low, the following techniques should be adopted: 1. Stock early, that is, stock immediately after the fingerlings are combined into ponds, so as to make full use of the growing period. Stocking rate is calculated at a maximum water depth of 2 m, generally 125-150 kg per mu. The stocking ratio is generally about 40% silver carp, about 10% bighead carp, about 30% grass carp and bream, and about 20% black carp and common carp.

The layout of a goose farm requires careful consideration; only scientific planning allows for successful goose rearing
1. Site selection. The site should be close to a water source, with the water surface as wide as possible, a water depth of 1-2 m, and good water quality, and a bit far from residential areas; the soil is best if it is sandy loam, with convenient transportation and a south-facing orientation. 2. Scale determination. The production scale is determined by investment capacity, rearing conditions, technical strength, sources of goslings, and product @#@136@#@, etc. Only by achieving batch production can greater rearing benefits be obtained. 3. Overall planning. First, the buildings should be divided into a production area and an administrative area and living area, with the two areas separated by more than 50 m and separated by a wall.
