What is the best season for river shrimp farming?
Summary Currently river shrimp farming generally adopts a two-season model of summer-autumn and winter-spring. Those stocked from mid-July to early August of the same year and harvested and marketed around the Spring Festival are summer-autumn river shrimp; those stocked in early March of the following year and marketed in mid-to-late June are winter-spring river shrimp. River shrimp can each year

What are the water change requirements during koi carp farming
Summary: When the water color and water quality change due to overfeeding or underfeeding, only a partial water change is needed; if the water quality is very poor and the moss in the water is too long, affecting the growth and development of the fish, then a complete water change should be carried out. A partial water change only requires making

What water temperature is suitable for river shrimp farming? Detailed explanation of the suitable temperature
Summary River shrimp can survive in water temperatures of 0-40°C, their growth water temperature is 10-30°C, and the most suitable water temperature for their growth is 25-28°C. When the water temperature is above 10°C, river shrimp begin to feed, and their feeding capacity increases as the temperature rises; when

What should be noted in catfish farming? These key points are crucial
Summary In catfish farming, the pond area should be large and the water should be somewhat deep. Anti-escape facilities should be installed around the pond. During the farming process, the water in the pond should be changed regularly, and some aquatic plants of suitable height such as water hyacinth can also be planted in the pond, which can both purify the water quality and provide shade for the catfish.

What Feed Is Best for Raising Carp? A Detailed Guide to Scientific Feeding Methods
Abstract When raising carp, you can feed them fish cake, soybean cake, barley, rice bran, wheat bran, silkworm pupae, corn meal, animal offal and other artificial compound feeds as well as various commercial feeds. When feeding, strictly adhere to the "four fixed" principles, and adjust the feed composition according to the different growth stages of the carp to ensure adequate and balanced nutrition. Generally, feed twice a day, and the specific feed to be given needs to be adjusted according to the weather, water temperature and the feeding situation of the fish school.

What water level is suitable for river shrimp farming?
Abstract: For river shrimp at the seedling stage, the water level should be around 60cm; in the middle and late stages of farming, the water level should be above 1.5m, and about 5cm of water needs to be changed every day, with live bacteria added to keep the water fresh. River shrimp farming should be kept away from wastewater pollution sources; the shrimp pond is best built in a location with good lighting and ventilation.

What are the environmental requirements for catfish farming
Summary A farming environment with suitable water temperature and clear water quality will make catfish grow faster and produce higher yields. Catfish generally live in the middle and lower layers of lakes or ponds and can adapt to various environments; they can even grow when water quality is poor. They belong to

What conditions are needed for river shrimp farming? A detailed explanation of the farming environment requirements
Summary Pond requirements: You need to choose a pond with loam soil as the pond bottom, relatively hard soil on the pond slope, good water retention without leakage, and easily regulated water levels, with an area of about 3-5 mu. Water quality requirements: The water body for farming river shrimp can be the same water body used for farming fish. Base fertilizer can be used to fertilize

How many years does a sturgeon generally need to be farmed before it can spawn?
Summary According to relevant research, female fish are around 16-29 years old when they spawn, and their body weight generally reaches around 170-300 kg, while male fish reach sexual maturity at around 9-22 years old, with a body weight of around 40-125 kg. The fish school stops feeding during the spawning period, and the optimal hatching water temperature for the eggs is around 20°C.

Mantis Shrimp Farming Conditions: Water Source and Water Quality Are Key, Keeping Water Temperature Well Controlled Makes Them Grow Fast
Abstract Farming mantis shrimp requires an abundant water source and good water quality. Cement ponds are best for the farming pond, and the size of the nursery pond should preferably be controlled at around 9×4×1.2m. The water temperature should be kept between 20-27°C, the water visibility at around 30cm, more than 1/4 of the water should be changed every day, and the oxygen content in the water should be maintained at
