Problems solved by technology

[0003] A few points should be paid attention to in the cultivation of freshwater lobster: Do not raise too many bottom fish, and remove miscellaneous fish before placing lobster seedlings and during lobster breeding to prevent lobsters from being swallowed; Lobster farming will reduce the size and output of lobsters and increase the cost of farming; lobster seedlings should not be selected from natural bred lobsters in chai ponds and reed ditches, and it is not suitable to breed lobsters in fish ponds, which will affect the size and output of lobsters and waste water resources, not easy to produce economic benefits
[0004] At present, some freshwater lobster breeding methods are unscientific, resulting in freshwater lobsters containing antibiotics, hormones and other drugs, excessive heavy metals, and even parasites and pathogenic bacteria, posing a threat to people's health

Abstract

The invention provides an environment-friendly lobster culture method. The method comprises the following steps of 1, selecting a pond with sufficient water without sludge, arranging a heat preservation shed on the top of the pond, arranging anti-escaping equipment, draining off water in the pond, and removing natural enemy organisms of lobsters to acquire an empty pond; 2, pouring water into theempty pond acquired in the step 1, after quick lime is put to disinfect the pond, planting aquatic plants, putting slow-release nutrients, placing a shelter, and adjusting the temperature, dissolved oxygen content and a PH value of water in the pond to obtain a culture pond; 3, feeding the lobsters, wherein young lobsters of which the length is 0.8-1 cm are selected and put into the culture pond and are fed with boiled primary feed twice a day from the first week to the seventh week, after the eighth week, the lobsters are fed with traditional Chinese medicine feed according to the water temperature, the water quality is improved every three to five days, and young grass carp and snails are put into the pond. The environment-friendly lobster culture method promotes the rapid growth of thelobsters and increases the yield of the lobsters on the basis of ensuring the health of the lobsters free of pollution.

Description
