Green shrimp breeding technology

It's time for the shrimp to reproduce! Here's a straightforward method for fishermen to breed their own shrimp at home. **Breeding Pond Preparation** 1. Drain your fish pond and let it dry for about a week. Then, spread 20 pounds of phosphate fertilizer per mu evenly across the bottom before refilling with water. 2. Use an 80-mesh filter to clean the incoming water before it enters the pond. 3. Two days after filling the pond with water, start introducing broodstock shrimp. For each mu, add 7 kg of female shrimp and 3 kg of male shrimp. 4. When selecting shrimp for breeding, choose those with bright green tails and larger size, as they are more likely to produce bigger offspring. Shrimp often molt when moved, so quality is key. **Monitoring Shrimp Development** 1. Check for shrimp larvae: In the first stage, look inside the female shrimp’s abdomen—before the eggs hatch, you should see them in the pouch. If many have separated from the mother, use a white ceramic bowl to scoop water from 30 cm below the surface. Look for small, snowflake-like particles. If you spot these, it means shrimp larvae are present. It's time to start feeding them soy milk. 2. A few days later, check again. You may see tiny, matchstick-shaped creatures with a head and tail. If you find them, you’ve successfully hatched the second stage. After three more days, the shrimp will be fully developed, swimming backward with their bellies up. Don’t worry—it’s normal. Wait another 3–4 days until they can swim like regular shrimp. At this point, they’ll be around 3,000 to 5,000 per pound, and no longer need to be fed milk. Now, you can transfer them to a culture pond. **Culture Pond Management** 1. Prepare the pond similarly to the breeding pond, but ensure the water depth is at least 80 cm. 2. Restock in late June or early July. 3. Stock about 3,000–5,000 shrimp per 15 kg (dry weight), or roughly 10,000 per 10 kg. To catch them, grow some aquatic plants like water peanuts in the pond and use a net to "snap" the shrimp hiding under the plants. You can also set up a trap cage behind the net. 4. Install oxygenation equipment during summer to prevent hypoxia. Avoid standing water along the pond edge for more than a week. 5. By mid-July, introduce 10 flower buds, 15 white pelicans, and 5 grass carp, all smaller than 20 cm in size. 6. Start selling small catches by the end of October. This method ensures a successful shrimp breeding cycle, from hatching to market-ready size. With proper care and timing, fishermen can enjoy a sustainable and profitable shrimp farming operation.

The instrument workbench adopts high-precision horizontal air floating track and rolling vertical track, with high movement accuracy, good stability, and long service life; High measurement efficiency, convenient card installation, simple operation, suitable for use in workshop inspection stations or measurement rooms. This instrument can further develop software according to the needs of users, meet their measurement shape requirements more widely, and is equipped with various equipment components for users to choose and use according to their own requirements.

A Profilometer is a precision equipment used to measure the shape of various mechanical parts' lines and cross-sectional contours. In the bearing industry, it is possible to measure the contour shapes of various rolling elements and raceways, such as protrusion, contact angle, surface curvature radius, and reference part angle. In the mechanical industry, it is possible to measure the straightness, line profile, parallelism, inclination, and angle of various parts. Especially suitable for measuring the appearance of pistons in automobiles, tractors, and motorcycles. The production instruments of this research run enterprise are controlled by microcomputers, which automatically achieve measurement cycles, eliminate installation errors, directly display the shape and parameters of the measured parts, and can print graphics and data for product quality testing and process analysis.
