What is the usual per-mu yield of river shrimp farming?

River shrimp, also known as oriental river prawn, is relatively common in rivers, lakes, reservoirs and ponds. Because its flesh is tender, its taste is delicious and its nutrition is rich, it is deeply loved by people. At present, river shrimp is a high-protein, low-fat aquatic food product, and it is farmed in many regions, so what is the per-mu yield of river shrimp?

1. What is the per-mu yield of river shrimp?

The per-mu yield of river shrimp is about 3000 jin, but due to factors such as the geographical environment, variety and farming management techniques, the yield will differ. Generally speaking, with good farming management techniques, a good variety and a good geographical environment, one mu can produce more than 3000 jin.

2. What do river shrimp eat?

River shrimp is an omnivorous animal. At the juvenile stage, it feeds on plankton. In natural waters, the main food of adult shrimp is various small benthic invertebrates, the corpses of aquatic animals, attached algae, various filamentous algae, organic debris, plant fragments, etc. Artificially farmed river shrimp can feed on various commercial feeds, such as distillers' grains, tofu residue, soybean cake, silkworm pupae, mussel meat, wheat flour, fish meal, cooked rice and river snails, and especially like to eat maggots. When feed is insufficient, they will also cannibalize one another. They are negatively phototactic to light, mostly hiding in dark places during the day and coming out at night to feed and move about. Therefore, feed is mostly put in after dark.

Under artificial farming conditions, compound feed can be used. They especially like to eat animal feed such as snail and mussel meat, earthworms, small trash fish, fly maggots and silkworm pupae, so it is better to appropriately add some animal feed during the farming process.

The oriental river prawn is an omnivorous shrimp species and is not demanding about bait. Juvenile shrimp feed on plankton, and after that they eat aquatic insects, plant fragments, organic debris, the corpses of aquatic animals, etc.

Under artificial farming conditions, adult shrimp can eat various fish-farming baits (rice bran, raw bran, soybean cake, mussel meat, snail meat and fish meat), and especially like to eat fermented feeds such as distillers' grains.
