How to Raise Grass Shrimp? A Detailed Guide to Farming Techniques and Precautions

The nutritional value of grass shrimp is still quite high, so more and more people enjoy eating grass shrimp, and they often cook grass shrimp at home. The shrimp meat of grass shrimp has effects such as tonifying the kidney and strengthening yang, promoting lactation and resisting toxins, nourishing blood and consolidating essence, resolving blood stasis and detoxifying, boosting qi and nourishing yin, dredging collaterals and relieving pain, and stimulating the appetite and resolving phlegm. So basically everyone can eat them. Next, I will briefly introduce some farming techniques for grass shrimp.

How to Raise Grass Shrimp

1. Feeding amount: feed precisely and reasonably according to the physiological needs of the shrimp at each growth stage and their living state at the time. The daily feeding amount of grass shrimp (compound feed) is generally calculated according to the body weight of each shrimp. For 1g body weight, the feeding amount is 16% of body weight; for 2g body weight, 14%; for 3g body weight, 12%; for 5g body weight, 10%; for 8g body weight, 8%; for 15-20g body weight, 6%-5%; for 20-30g body weight, 5%; for over 30g body weight, 4%.

2. Disease prevention and control, with prevention as the main approach. In the early stage, use Shadu Ling to disinfect once every 15 days; in the middle stage, disinfect once every 10 days; in the later stage, disinfect once every 7 days. Disinfect promptly after strong winds and heavy rain, and disinfect promptly when water quality becomes abnormal. In addition: pay attention to patrolling the pond regularly, observe the activity of the shrimp, and handle any problems promptly.

Grass Shrimp Farming Techniques and Precautions

1. Ponds should be built in areas with flat terrain, little silt, sufficient water sources, good water quality, no pollution, and convenient water intake and drainage. It is advisable to use a mud-sand bottom with an area of 5-8 mu, a water depth of 2m, and 2-3 units of 2.2kw aerators per pond. For old ponds, remove the sludge and weeds in the pond or carry out plowing, and expose the pond bottom to the sun.

2. Fill the pond with 15-20cm of water 20 days before releasing the seedlings to soak the pond, and choose a pond-clearing agent to splash over the whole pond to kill harmful microorganisms. For some newly excavated ponds and some aged ponds with relatively poor water exchange capacity, in order to prevent the explosive reproduction of harmful algae in the middle and later stages of farming, attention should be paid in advance to using algae-removing agents, such as Miezao Wang, Bucaoping and other drugs, to kill harmful algae at the bottom of the pond.

3. The use of Xiateli has a comprehensive effect. Once Xiateli is put into the pond, diatoms can be cultivated within 2-3 days. After cultivating the basic biological bait and confirming that the water quality meets the requirements, release the seedlings.

4. Do not release seedlings when the weather is bad. Seedlings should be released on a clear morning at 8-9 o'clock or when the sun sets in the afternoon; do not release seedlings at noon. Do not rush to release seedlings if pond clearing and pest elimination are not thorough. Do not release seedlings if the pond water color is poor and the water quality is poor.

What Do Grass Shrimp Eat

1. Grass shrimp are omnivorous shrimp and are not strict about bait. Young shrimp feed on plankton, and later they eat aquatic insects, plant fragments, organic debris, and the carcasses of aquatic animals.

2. Under artificial farming conditions, grass shrimp can eat various fish-farming baits (rice bran, raw bran, soybean cake, clam meat, snail meat and fish meat), and especially like fermented feed such as distillers' grains. When feed is insufficient, they will also eat each other. They are negatively phototactic to light, mostly lurking in dark places during the day and coming out at night to feed and move about. Therefore, feed is mostly put in when it gets dark.

3. Grass shrimp, the rostral formula is 7-8/2-3. The carapace has antennal spines, hepatic spines and gastric teeth, with no frontal gastric ridge, and the hepatic ridge is obvious and straight. The lateral rostral groove is short and does not extend backward beyond the middle of the carapace. The fifth pereiopod has no exopod. The body is arranged in alternating dark green, dark brown and light yellow transverse bands, forming bright patterns on the abdomen.

How Big Can Grass Shrimp Grow

1. Grass shrimp have strong vitality, delicious meat, and a large individual size. They are the largest species in the genus Penaeus. The largest female shrimp can reach 33cm in length and exceed 500g in weight. They have two pairs of small chelae, and the inner surfaces of the two fingers of the chelae are concave, slightly spoon-shaped. The ends of the spoon fingers have brush-like setae (bristles), which are a sharp tool for scraping algae, so they often feed by scraping algae, but their algae-cleaning ability is not as good as that of the Yamato shrimp. Their body color is extremely variable and changes with environmental changes.

2. Under certain circumstances (female shrimp being startled, sudden changes in water quality), female shrimp may kick off the eggs on their abdomen, or directly molt and abandon all the eggs (the eggs adhere to the swimming legs on the shrimp's abdomen), or the egg-bearing female shrimp may die unexpectedly.

I have just briefly introduced some farming techniques and precautions for grass shrimp. In fact, with the improvement of people's living standards today, everyone has the ability to buy some good food, so farming grass shrimp still has very good commercial prospects. After all, it is also a healthy green food.
