Culture method for controlling fishpond water in tropical zone plectropomus leopardus RAS

Abstract

The invention belongs to the field of fish culture water body control, particularly relates to a culture method for controlling fishpond water in tropical zone plectropomus leopardus RAS, and providesthe following scheme aiming at the problems of slow pond fish growth, poor stress resistance, low survival rate and the like under the existing plectropomus leopardus industrial culture mode. The method comprises the following steps that S1, culture pond facilities and culture water in a culture pond meet the control requirements that a culture pond is required to be square or round, the area ispreferably 3 m*4 m, the pond depth is required to be 1.2 m-1.4 m, the water depth is required to be 0.7-0.8 m, a sewage draining exit and a water changing pipe are arranged in the center, a sewage draining and water changing adjusting pipe is arranged outside the pond, and culture water circulation times are controlled to be 8 to 12 every day; and S2, for fishpond water inlet pipe arrangement andwater body flow velocity control requirements, two fishpond water inlet pipes are arranged and are respectively positioned at diagonal parts of the culture pond. The unit yield, the stress resistanceand the survival rate of plectropomus leopardus can be improved, and the culture benefit is improved.

Description

technical field

[0001] The invention relates to the technical field of fish breeding water body control, in particular to a breeding method for controlling the water body of fish ponds under RAS of leopard gillfish RAS in tropical areas. Background technique

[0002] Plectropomus leopardus, commonly known as East Star Spot, belongs to the order Perciformes, suborder Percoidei, family Serranidae, genus Plectropomus, and is a high-grade marine economical edible fish kind. The body and head of Leopard spiny perch are olive to reddish brown, the head, body and fins are covered with tiny blue spots, the pectoral fins are red, and there is an inconspicuous dark band at the rear edge of the caudal fin. It is a warm-water island and reef fish, mainly distributed in the western Pacific Ocean to the Indian Ocean, from southern Japan in the north, Australia in the south, Fiji in the east, and the east coast of Africa and the Red Sea in the west. It is distributed on the east coast of...

Embodiment 1

[0026] refer to Figure 1-5 , a kind of culture method of fishpond water control under leopard gillfish RAS in tropical area, comprises the following steps:

[0027] S1. Requirements for aquaculture pond facilities and aquaculture water control in aquaculture ponds: fish ponds can be square or round, with an area of ​​3m×4m, a pool depth of 1.2m, a water depth of 0.7m, and a sewage outlet and water change pipe in the center. , The outside of the pool is equipped with a sewage discharge and water change adjustment pipe, and the number of water cycles in the aquaculture water body is controlled at 8 times a day;

[0028] S2. Fish pond inlet pipe setting and water flow rate requirements: There are two fish pond inlet pipes, which are located at diagonally opposite corners of the aquaculture pond. , to ensure that the entire fish pond culture water body is in a counterclockwise rotation state, and the average flow rate of the water body is controlled at 10cm / s;
