How to keep guppies alive? A complete guide to breeding techniques for beginners
Setting up a tank Most people think the first step in keeping fish is to just buy the fish first, but this is actually not quite the right idea, because if the tank and the fish are bought together, problems often arise, which will be described in detail later. If you have already decided to keep fish, then you should first go and choose

Key Technical Points for Grouper Culture in Earthen Ponds
Grouper is delicious and comes in a dazzling variety of forms, and is deeply loved by consumers everywhere. At present, cage culture is common in our country, but as the marine environment changes, cage culture suffers from more diseases that are difficult to control, so promoting grouper culture in earthen ponds is highly worthwhile. 1. Pond selection

Detailed Explanation of Ecological Breeding Techniques for Rice Field Eel Farming
1. Ripening and spawning induction of parent eels: After late May, when the water temperature reaches 25°C, each parent eel is first injected with LRH-A (luteinizing hormone-releasing hormone) 12.5 micrograms, injection volume 0.5 milliliters, to ripen the gonads; 7 days later, inject DOM (domperidone) 0.5 micrograms, injection volume 0.5 milliliters, or LRH-

Key Technical Points for High-Yield and High-Quality Freshwater Shrimp (Macrobrachium nipponense) Aquaculture
(1) Monoculture of freshwater shrimp in ponds. 1. Pond conditions: area of 5-10 mu, water depth of 0.8-1.5 m, firm and leak-proof pond embankments, slope of 1:(2-3), flat pond bottom slightly inclined toward the drainage outlet, and silt not exceeding 20 cm. 2. Preparation before stocking: ① Chemical pond clearing: 7-10 days before stocking, fill with 20 cm of water, apply 100-125 kg of quicklime per mu after slaking, and splash evenly over the entire pond for clearing and disinfection to remove wild fish and harmful organisms; ② Aquatic plant planting: species include Hydrilla verticillata, Potamogeton maackianus, etc., with the planting area accounting for 30-50% of the pond area, then fill with water and fertilize. 3. Water quality management: ① Use microbial preparations: such as EM bacteria, photosynthetic bacteria, etc. From late August to early November, use biological bacteria once every 15 days depending on the medication situation to improve the pond water environment. ② Microporous aeration: equip one 3 kW microporous aeration pump for every 20 mu, lay main pipes parallel to the two long sides of each pond, and install 6 disc-type microporous pipe discs with a diameter of 1.5 m per mu of pond. Dissolved oxygen should be above 5 mg/L. When dissolved oxygen in the shrimp pond falls below 5 mg/L, turn on the aeration pump. Aeration time is generally from 12:00 to 16:00 in the afternoon and from 24:00 at night to 6:00 the next morning, and should be extended on rainy or muggy days. 4. Feeding management: mainly feed complete compound feed for freshwater shrimp of different specifications at different stages, supplemented with rice bran and other feed in the early stage. Feed twice a day, with 1/3 in the morning and 2/3 in the afternoon. Adhere to the "four observations" (observe the season, observe the weather, observe the water color, observe feeding activity) and the "four fixeds" (fixed time, fixed location, fixed quality, fixed quantity). The daily feeding amount is 3-7% of shrimp body weight, and the specific feeding amount should be consumed within 2-3 hours. The feed coefficient for the whole season is 1.5-1.8. (2) Mixed culture of shrimp and crabs in ponds. There is no limit to the pond area, but generally no more than 50 mu is appropriate, with a water depth of 1.0-1.5 m. Pond clearing, disinfection, and grass planting are carried out according to the operating procedures for river crab culture. Stock 5-8 silver carp and bighead carp per mu, put in 200-250 kg of live snails per mu, and plant aquatic plants mainly including Hydrilla verticillata, Potamogeton maackianus, Elodea nuttallii, etc., with the aquatic plant coverage controlled at about 60%. During the growth period of young shrimp in autumn, apply fertilizer appropriately and feed a small amount of powdered feed. When using insecticides and disinfectants, avoid both the peak molting period of river crabs and the peak molting period of freshwater shrimp.</p>

Hatchling turtle rearing has its finer points: these eight breeding techniques must be mastered
Turtles hatched from eggs are called hatchlings. When hatchlings emerge from the shell, they generally weigh 3 to 13 grams, with tender bodies and weak mobility, and they do not adapt well to the environment. If not carefully reared, they easily die. Therefore, doing a good job of rearing hatchlings is the most critical part of turtle farming. The following introduces eight

Paddlefish Farming Techniques and Conditions: Both Monoculture and Polyculture Require the Addition of Silver Carp
Summary Models: There are two models, monoculture and polyculture, but both require the addition of silver carp, which can control the amount and growth rate of algae and avoid water eutrophication. Density: Under the monoculture model, at a body length of 50-60 cm and a weight of 1 kg, 80-100 fish per mu; at 2-3 kg, 40-50 fish per mu

Efficient Technical Methods for Breeding Toads in Rice Paddies
The toad is a highly valuable amphibian and reptile used for both food and medicine. The toad skin (chan yi) that it naturally sheds and the milky secretion (chan su) collected and processed from its post-auricular glands are precious traditional Chinese medicinal materials. With the depletion of wild resources, artificial breeding is imperative. Using rice paddies to raise toads offers complementary advantages and can form

Detailed Explanation of the New Technology for Raising Fly Larvae in Plastic Greenhouses
Raising flies in cage nets in ordinary civilian houses is a technology commonly adopted in the fly farms that have emerged in China in recent years. This technology requires heating facilities to be installed in the room; otherwise, when the indoor temperature in autumn, winter and spring cannot reach 27°C, the reproductive capacity of the flies drops severely.
