Embodiment 1

[0017] 1. Method

[0018] 1. Selection of cultivation facilities: Select 2 outdoor prawn breeding cement ponds at the Donghai Island Marine Biological Research Base of Guangdong Ocean University, with an area of ​​0.1 hm 2 , and equipped with a sewage system and an aeration system, the aeration system is a turbo aerator; 50m 3 There are 4 outdoor aquaculture wastewater degradation pools; indoor controllable photolarvae and juvenile fish cultivation workshops.

[0019] 2. Shrimp farming:

[0020] (1) After the water in the outdoor prawn breeding cement pool is drained, sterilize with 1200kg of quicklime per hectare; after 3 days, after the toxicity passes, extract the filtered seawater to make the water level reach 1.5m; apply urea 75kg / hm 2 , superphosphate 7.5kg / hm 2 To cultivate basic bait organisms, the amount of fertilizer should be flexibly controlled according to the bottom quality of the shrimp pond; when a large amount of basic bait grows in the water body, that is,...

Abstract

The invention discloses a facility and a method for indoor large-scale cultivation of larvae and juveniles of Sillago sihama using prawn cultivation wastewater and belongs to the technical field of artificial breeding of fishes. The facility comprises two to three prawn cultivation ponds 0.07hm<2> to 0.2hm<2> in area, two to four outdoor cultivation wastewater degradation ponds 50m<3> in volume, an indoor controllable light shop for larva and juvenile cultivation, and a pumping system. The cultivation wastewater of the mid-late phase of prawn cultivation is biologically treated, after organics in the wastewater are degraded, the wastewater is used for cultivating the larvae and juveniles of Sillago sihama in an indoor cement pond on a large scale, zooplanktons in the degraded wastewater are used as feed additive, algal solution in the degraded wastewater is added to cultivation water for cultivating the larvae and juveniles of Sillago sihama, the quality of the cultivation water can be stabilized, and the larvae and juveniles of Sillago sihama are protected from being scared. The method and the facility have the advantages that prawn cultivation wastewater can be effectively utilized, environmental pollution is decreased, and survival rate of the larvae and juveniles of Sillago sihama in indoor shop large-scale cultivation is increased.

Description

technical field [0001] The invention relates to a method for large-scale cultivation of squamous larvae and juveniles, in particular to a method and facilities for indoor large-scale cultivation of squamous larvae and juveniles using prawn breeding wastewater, belonging to the artificial breeding technology of fish field. Background technique [0002] Sillago sihama Forskál belongs to the order Perciformes, the suborder Percoidei, the superfamily Percoidea, the family Sillaginidae, and the genus Sillago. It is distributed in Australia, India, Indonesia, the Philippines and Japan. It is also distributed in the Bohai Sea, Yellow Sea, East China Sea and South my country Sea in China, with a body length of up to 300mm. Commonly known as sand drill, boat smallfish, and wheat ears, the multi-scaled carp is an important economic fish in my country's coastal areas and occupies a very important position in my country's offshore fishing operations. However, due to overfishing in rece...
