Cultivating technology of Eriocheir sinensis megalopas in inland freshwater lake

Abstract

The invention discloses a cultivating technology of Eriocheir sinensis megalopas in an inland freshwater lake and belongs to the field of aquaculture. The invention provides the cultivating technology of the megalopas of Eriocheir sinensis by controlling key steps such as culture pond preparation, sterilization and water quality regulation and daily management; by implementing the cultivating technology, the cultivated megalopas are low in cultivation cost, young Eriocheir sinensises are high in survival, consistent in transformation time, and neat in height and can be cultivated on a large scale.

Description

1. Technical field: [0001] The Chinese velvet crab -grained larvae cultivation technology in the inland freshwater lake belongs to the field of aquaculture technology, especially involving the cultivation technology of Chinese velvet crab large -eye larvae in the inland freshwater lake. 2. Background technology: [0002] Inland freshwater lakes are away from both the coast and the freshwater lake in the inland arid areas. Among them, the largest freshwater lake in China is the Bosteng Lake in Xinjiang.Larger; [0003] The big -eyed larvae MEGALOPA is the Metazea (Metazea), which is equivalent to shrimp and shrimp larvae.During the transition from floating to the bottom, many algae that can be discovered on drifting, because it has a large pair of large reunion to the end of the long eye handle and is named outside the eye socket.The shape of the big -eyed larvae is in the transitional stage between the larvae and the crab. The large -eye larvae already have a stronger ability to...

Problems solved by technology

[0004]Because the inland freshwater lake is deep inland, the distance is long, the climate is dry, the temperature difference between day and night is large, and the water temperature and water quality are quite different from other freshwater lakes. Most of the crabs are mainly raised by feeding young crabs directly. The cost of young crabs is high and the cost of long-distance transportation is also high; taking megalopa as an example when they are cultivated into young crabs in cages and stocked in the waters of Bosten Lake, although the problem of seedlings and crabs is solved. The problem of high transportation costs, but due to the inadaptability to water quality, temperature, environment and food, and after long-distance transportation, the survival rate of megalopa into juvenile crabs is low, and some are difficult to decompose into juvenile crabs, and the degeneration time is inconsistent. The size is uneven, which seriously affects the output and quality of commercial crabs
