How much money can you earn by raising 20 mu of lobster?

Lobster is delicious food, the profit of breeding is very considerable, about 120jin of shrimp is planted per mu, and the annual yield per mu can reach about 3000 jin. The shrimp species can be put in one time, and they will no longer buy species within 3 years. Moreover, the offspring are not degraded or mutated, and the yield per mu remains unchanged for a long time. Let's take a look at how much money can be earned by raising 20 mu of lobster.

Can you make money from lobster farming?

Judging from the market rules of the past few years, the price of lobster was relatively high when it was first listed on the market, and declined relatively when it was listed in May and June. After August and September, the volume of the pond was less, and the price rose again. Moreover, in recent years, the demand for lobster in the domestic market is very strong. In large and medium-sized cities such as Wuhan, Wuxi, Nanjing, Changzhou, Suzhou, Huaian, Shanghai and Hefei, the annual consumption of lobster is more than 10,000 tons. Strong consumer demand provides a broad development space and potential for the development of lobster aquaculture, so the development prospect of lobster farming is broad.

How much money can you earn by raising 20 mu of lobster?

At present, based on the estimate of 120jin shrimp per mu, the number of female shrimps per mu is 120jin / mu × 20 / jin = 2400 / mu, 1140 / mu × 200 / times / 2 times / year = 456000 / mu / mu. The survival rate from spawning to young shrimp is 8% to 30%. According to the minimum 8%, the total number of adult shrimp is 456000 / year × 8% / mu, and the eggs can be put on the market in 23 months. The body weight of each adult shrimp grows to 50 grams (about 10 / jin), and the total annual yield per mu is 36480 / mu / 12 / jin = 3040 jin / mu, then the annual gross profit per mu is 3040 jin × 8 yuan / jin = 24320 yuan / mu. Net profit = gross profit 24320 yuan ~ seed purchase cost (120jin × 48 yuan) 5760 yuan = 18560 yuan / mu, 20 mu lobster can earn 18560 yuan / mu × 20 mu = 371200 yuan a year.

What problems should be paid attention to in raising lobster?

1. Seedling: there is no "hybrid variety" of lobster. At present, natural seedlings are abundant and cheap, but artificial seedlings are still in the laboratory stage. In addition, do not mistakenly believe that lobster species are bought at a high price from other places after domestication and killing each other less. There are also many people think that as long as they put into planting lobsters in the first year, they can get good profits every year through their own continuous reproduction. in fact, the yield of lobster culture is the highest in the first year, and then decreases year by year. Because the life cycle of lobster is 16-18 months, coupled with inbreeding, functional degradation, disease resistance decline, the yield will drop sharply or even no harvest after 3 years.

2. Water quality: some people think that lobsters can also grow well in smelly ditches, but not both good and bad water can be raised. Fresh water quality is the key to the high yield of lobster culture. It is required that the coverage of aquatic plants in the pond should be 30-60%. The transparency of the water body is about 30 cm, the dissolved oxygen content is more than 5 mg / L, the water should be changed regularly, and the water level is kept above 80 cm in the high temperature season.

3. Feed: lobster is an omnivorous animal bait creature, and its growth depends on the intake of protein. It can be mainly composed of fresh miscellaneous fish and field snails, supplemented with plant food, or a compound feed with a protein content of no less than 32%. Rotten animal and plant feed should not be fed because of its low utilization rate and easy to deteriorate the water quality.

4. Disease: some people think that "lobster will not get sick". In fact, it is not. After high-density culture, various environmental factors are easy to cause lobster disease. The solution is mainly prevention and regular use of drugs. In the process of culture, the water body should be disinfected regularly. If the pH value of the water is less than 7, quicklime should be pulped at a concentration of 20 grams per cubic meter and sprinkled evenly every 15 to 20 days. In general, the pond was disinfected with chloride every 15 to 20 days, and molting growth-promoting hormone was added to the feed every half a month for 3 days.

5. Mixed culture: many people think that lobster can be mixed with fish in order to make rational use of space and improve the efficiency of aquaculture. In fact, lobster must not be mixed with carnivorous or omnivorous aquatic products. Because the lobster is most likely to be eaten when it is shelled, and silver carp and bighead carp are its natural enemies when the lobster is born, so mixed culture is not recommended.

6. Management: some farmers think that lobsters have miscellaneous food habits and can be fed casually, so some people do not put bait in intensive lobster ponds, causing lobsters to eat each other, or overfeeding animal internal organs to cause organic matter fermentation and smelly water. Produce toxic gases and hypoxia, resulting in culture failure.

7. Yield: the yield per mu of lobster is closely related to stocking density, culture environment, feeding amount, disease control and so on. Lobsters grow fast and can be sold for 50 to 70 days in general. May to June is the peak sales season. After the end of June, they begin to mate, lay eggs and live in caves, and the catch decreases sharply, so the rumors that the lobster culture output is more than 1000 jin and the benefit is tens of thousands of pounds is not credible. Generally speaking, the lobster culture output per mu is about 250kg / mu, with an output value of 1500kg / mu and 2500 yuan.
