The invention relates to a culture method of early-breeding seedlings of Charybdis
japonica, which is characterized by comprising the steps of parent crab culture, egg-carrying crab culture,
larva culture and the like. Aiming at the biological characteristics of the breeding of the Charybdis
japonica, by utilizing the existing facilities for
industrial culture of the seedlings of river crabs and the technical means such as regulation and control of ecological conditions, reasonable feeding,
disease control and the like, the invention cultures the early-breeding seedlings of the Charybdis
japonica required for culture production, the early-breeding seedlings have longer growth period and large scale in the market, and the economic benefit can be obviously improved. The experiment proves that the invention can realize
industrial culture of the early-breeding seedlings of the Charybdis japonica, can solve the problem that
seawater ponds in coastal areas are used for culturing the Charybdis japonica depending on natural seedlings, can fully utilize the existing facilities for the culture of the seedlings of shrimps and crabs and
seawater culture ponds, improves the economic benefit of
seawater culture in the coastal areas, has important economic significance and
social significance, and has the characteristics of science, rationality, low investment and high practicability.
