How to Improve the Utilization Rate of Winter-Idle Fish Fry Ponds
After the winter pond consolidation until the release of summer fry the following year, most fish fry ponds have an idle period of about half a year. If they are comprehensively utilized, the utilization rate and economic benefits of the fish fry ponds can be greatly improved. Four methods of utilizing winter-idle fish fry ponds are introduced below. Raising market-size fish: Using winter-idle fish fry ponds to raise one season of market-size fish can both increase output and help regulate the "summer shortage" aquatic product market. Because the rearing period is relatively short and the temperature is relatively low, the following techniques should be adopted: 1. Stock early, that is, stock immediately after the fish fry are consolidated into ponds, so as to make full use of the growing period. The stocking amount is calculated at a maximum water depth of about 2 m, generally 125 kg to 150 kg per mu. For the stocking ratio, generally silver carp account for about 40%, bighead carp about 10%, grass carp and bream about 30%, and black carp and common carp about 20%. Release @#@233@#@ large-size fingerlings, generally silver carp and bighead carp above 250 g, grass carp above 500 g, bream above 100 g, black carp above 1000 g, and common carp above 250 g. 2. Strengthen management. Fertilize promptly after the fish are stocked. Fertilization should mainly use organic fertilizer to ensure that the pond water has a certain fertility. In winter, choose clear and warm weather and feed once every 2 to 3 days, with the feeding amount at about 20% of the usual amount. In spring, as the water temperature rises, increase the feeding amount and maintain good water quality, so that the fish school maintains a relatively high growth rate and reaches the market size on schedule.

Using urea as a foliar fertilizer can double its utilization rate, but caution is needed when using it
Someone asked: Can the effect of urea as a foliar fertilizer be doubled? It is unclear which aspect "doubled" refers to here, specifically whether it is fertilizer efficiency or utilization rate. As for fertilizer efficiency, Science Xingnong cannot guarantee whether a doubling effect can truly be achieved,...
