Polyculture of yellow catfish and soft-shelled turtles can net 10,000 yuan per mu
In recent years, with breakthroughs in special feed for yellow catfish and in fry breeding technology, various farming models for yellow catfish, including main culture, polyculture and intercropping, have been rapidly applied. The "18221" efficient pond farming model uses high-economic-value yellow catfish to replace the traditional "four major Chinese carps" in a polyculture model with soft-shelled turtles. This model means that in 1 mu of farming water surface, 800 jin of yellow catfish and 200 jin of soft-shelled turtles are produced, with an output value of 20,000 yuan and a profit of 10,000 yuan. It is a typical high-yield, high-efficiency farming model. Its technical points: One

What are the factors affecting the efficacy of fishery drugs?
1. Dosage and dosage form of the drug. The effect of a drug varies with the dosage, and may even change qualitatively. For example, when the astringent metal drug zinc sulfate is used topically, a low concentration has an astringent effect, a medium concentration has an irritant effect, and a high concentration has a corrosive effect.

Four precautions for autumn fishing to keep in mind
First, choose a good fishing time. Fishing should be done on sunny days, around dawn before the fish surface for air. At this time, fishing has the least impact on the pond fish, and the freshly caught fish can be supplied to the morning market in time. In overcast, muggy weather, or when pond fish are surfacing for air or there is an outbreak of fish disease, it is not advisable to seine and catch fish, so as to avoid causing a large number of fish deaths and unnecessary economic losses. Second, stop feeding or feed less before fishing. One day before fishing, feeding should be stopped or the amount of feed reduced, and one must by no means feed large amounts of concentrated feed just to increase the weight of the fresh fish for market.

Key Points of High-Yield Technology for Integrated Fish-Lotus Culture in Ponds
0. Introduction The grid-pond fish-lotus integrated culture technology involves partitioning hardened lotus ponds with roof tiles, hard boards, etc. into small grids of 2-4 sq m each, and planting lotus within the grids. On average, each mu of water surface produces 0.5 wan kg of lotus and 400-450 kg of fish, with a net benefit of over 10,000 yuan per mu. This technology can utilize abandoned pits, wasteland, riverbank land, and scattered marginal land to build grid-pond fish-lotus integrated culture systems. It features small investment, low cost, quick results, and high efficiency, making it suitable for widespread development by rural households. It can both increase economic income and improve market
