Detailed Explanation of Key Points in the Quick-Freezing Processing Technology for Icefish
Quick-frozen icefish are exported to Japan, Southeast Asia, Europe and other places, and are especially popular with Japanese consumers. With the continuous increase in icefish yields from reservoirs, quick-frozen icefish has become one of China's export aquatic products with a relatively high foreign exchange earning rate. 1. Preservation and transportation of raw fish. Icefish have small bodies and thin skin, are highly prone to spoilage, and have a strong seasonal production period. To ensure the quality of the icefish, ice can be brought aboard the boat during fishing so that preservation can be carried out immediately.

What are the common symptoms when a fish is sick?
Generally speaking, there are some key points we focus on when observing a fish's appearance: 1. Body color: If you observe your fish often, you will know what its color looks like in its normal, healthy state. If it suddenly becomes darker or lighter, or even turns deathly pale, it means the fish may have a problem. 2. Behavior: If your fish is normally always lively and active, and suddenly it no longer likes to move, or even stays in one spot in the tank, sinking to the bottom motionless or floating at the surface, then this too is a sign of a problem.

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

Detailed Explanation of Key Points for Fish Fry Stocking: Do Not Overlook These Critical Points
For newly built ponds, soak in water for 1~2 days, then disinfect. Old ponds must be drained, thoroughly cleared of sludge and weeds, and treated by tilling, sun exposure, and rinsing to promote the oxidation, decomposition, and removal of organic matter, followed by disinfection. Commonly used disinfectants include quicklime, bleaching powder, and sodium dichloroisocyanurate. The disinfection method generally involves first filling the culture pond with 10~30 cm of water, dissolving the disinfectant in water, and splashing it into the pond. Cement ponds should be rinsed multiple times with the medicated solution, then rinsed with clean water. For example, one enterprise culturing whiteleg shrimp (Litopenaeus vannamei) performs disinfection 15

New high-yield techniques for lotus root: straw-fed lotus cultivation and lotus-fish polyculture
In April 2006, the Yindu Industry, Trade, Science and Technology Ecological Park in Wenshang County, Shandong Province, was completed and put into operation. Using waterlogged, saline-alkali and barren land, through scientific methods and the implementation of multi-component composite three-dimensional development, a science and technology ecological park was built integrating vegetable and forage cultivation - livestock and poultry breeding - straw-fed lotus cultivation - fish farming in lotus ponds - fishing and leisure - dining and entertainment, and other functions into a circular economy development model, achieving remarkable economic and ecological benefits. In particular, the new corn straw-fed lotus cultivation technique promoted by the park can achieve a lotus root yield of up to 6000 kg per mu.

The prospects for yellow catfish polyculture are good, and this farming model is worth paying attention to
Yellow catfish, also known as gayazi, huangga, angsi and so on, is an important economic fish in China's freshwater aquaculture. The flesh of yellow catfish is tender, nutritious and delicious, and market demand has continued to grow rapidly in recent years. Because the yield from natural waters and pond culture is very limited, it is difficult to meet the growing market demand, which has kept the market price of yellow catfish high for a long time. Polyculture of yellow catfish in ponds requires little investment and offers high returns, and the farming prospects are generally viewed favorably. Pond conditions: Ponds for polyculturing yellow catfish should be chosen with good water source conditions and no pollution
