Aquatic offspring seed intermediate cultivating system

Abstract

The invention discloses an aquatic offspring seed intermediate cultivating system. The aquatic offspring seed intermediate cultivating system is characterized by comprising a round cultivation pool (1), the cultivation pool (1) is communicated with a cultivation pond through a water pipe provided with a pumping device, and an inlet end of the water pipe is arranged along the tangential direction of the cultivation pool (1). A drain pipe (2) is arranged in the center of the cultivation pool (1), the other end of the drain pipe (2) is communicated with a waterweed purifying tank (3), the waterweed purifying tank (3) is connected with a biofilter (4) through the pumping device, and the biofilter (4) is communicated with the cultivation pond through the drain pipe. The cultivation pool (1) is made of thermal insulation material and provided with a cover body which is matched with the cultivation pool (1), and an electric heater with temperature controlled is arranged at the bottom of the cultivation pool (1). The aquatic offspring seed intermediate cultivating system has the advantages of being capable of guaranteeing cultivating water temperature, simple in operation, low in cost, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a cultivation system, in particular to an intermediate cultivation system for aquatic seedlings. Background technique [0002] Some famous and high-quality aquatic species in northern my country, such as prawns, swimming crabs and other aquatic animals, are restricted by climatic conditions and have a short growth cycle. Breeding users usually put in seedlings at the end of May or early June when the pond water temperature rises to a suitable temperature. If the seedlings are small at this time, the size and yield at harvest will be affected. These species are mostly cultured in a polyculture mode. After the seedlings are put into the pond, they cannot be fed intensively. At the same time, the small-sized seedlings are directly put into the breeding pond after being transported. They have poor tolerance to the environment and are vulnerable to harmful organisms. attacks, the survival rate is often low. Therefore need a kind o...

These species are mostly cultured in a polyculture mode. After the seedlings are put into the pond, they cannot be fed intensively. At the same time, the small-sized seedlings are directly put into the breeding pond after being transported. They have poor tolerance to the environment and are vulnerable to harmful organisms. attacks, the survival rate tends to be low
