Artificial propagation techniques for large icefish: Practical experience from Hongshan Reservoir
Hongshan Reservoir is located in the lower reaches of the Laoha River in the northeast of Chifeng City. It is a large plain-type reservoir integrating flood control, irrigation and aquaculture, with a catchment area of 24,500 sq km and a total storage capacity of 2.56 billion cubic meters. The reservoir's fish-farming area ranges from 80,000 mu to 130,000 mu between the dry season and the wet season. The reservoir introduced fertilized eggs of large icefish in 1995, and the catch reached 2.5 kg/mu in 1998. In the following 2 years the yield declined somewhat, but in recent years, thanks to relatively well-developed propagation management measures, the resource has gradually recovered.

How to Clear Wild Trash Fish from Fish Ponds? Four Methods to Solve It Easily
When filling, changing water, and feeding aquatic plants in intensive ponds, wild trash fish or their eggs such as sharpbelly, topmouth gudgeon, crucian carp, loach, and grass shrimp inevitably get mixed in. These wild trash fish not only have strong food-grabbing ability, a large feeding volume, and low economic value, but also reproduce quickly. In addition, carnivorous predatory fish such as snakehead and catfish can also swallow cultured fry. Therefore, various measures must be taken in aquaculture management to remove wild trash fish. 1. Kill the wild trash fish in the pond in advance. Before stocking fry, drain the pond water, let the pond bottom freeze and sun-dry for a period of time, then add 20-3

What serious consequences can result from not pruning Schisandra chinensis?
Some fruit growers, after cultivating Schisandra chinensis, stick stubbornly to their own views. Acting on traditional thinking, they do not prune, obstinately believing that "the wild Schisandra chinensis on the mountain is not pruned by anyone either, yet it still blooms every year and bears fruit year after year. Why is it that when cultivated artificially, it instead needs pruning? Isn't that a waste of labor and effort?" Little do they know that although wild Schisandra chinensis bears fruit every year, the amount of fruit borne per individual plant is very low, generally not even reaching one jin. Because of the influence of light and ventilation, only the few branches that climb to the highest point can bear fruit, and affected by the

Processing Technology for Water Chestnut Products and Health-Promoting Flavored Oil from Edible Fungi
The water chestnut is a perennial herbaceous plant; its edible underground stem is flat and round, with a reddish-brown or dark brown skin and white flesh. Deep processing of water chestnut products can increase their economic value. The processing technologies for these products are described below: (1) Water chestnut flour: Select fresh water chestnuts, discard the damaged and rotten ones, wash them clean with water, cut off the tail ends, mash them, add an equal amount of water, crush them with a grinder, then filter the slurry through gauze to remove the residue. After the water chestnut flour settles, pour off the clear water on top, spread 1 to 2 layers of cotton cloth over the flour, and use clean, dry bricks or tiles to absorb the remaining

How to determine if fish are suffering from pollution poisoning
Fish deaths can be caused by many factors such as disease, oxygen deficiency, toxic algae, mechanical injury, and pollution poisoning, and pollution poisoning is the most common type of fatal cause. Below are several methods for visually judging common types of pollution poisoning, for reference in production. Heavy metal pollution poisoning. Heavy metals refer to metals with relatively high density, such as lead, manganese, zinc, etc. The gills of poisoned fish appear grayish-white and secrete large amounts of mucus, forming flocculent deposits that block the gills and cause respiratory impairment; poisoned fish often float and swim at the water surface.

The Akizuki pear is a pear variety originally from Japan.
In Japan in 1991, it was selected by crossing Niitaka with Hosui, and then crossing that with Kosui. In 1998, it was officially registered as a variety. The fruit is oblate, weighs around 500g, and the skin is yellow-red-brown with a clean surface. The flesh is white and soft-textured, with a soluble solids content of 12%. It has a delicate, fragrant taste. It ripens in late September, 10d later than Hosui and 7d earlier than Niitaka. The tree is vigorous, with few flower buds on short fruiting branches, so artificial pollination is required. The flowering period is the same as that of Hosui, the fruit set rate of white flowers is low, and it has good productivity.
