Embodiment 1

[0017] 1. Cement pool conditions: select 2 hard bottom square cement pools with an area of ​​15 m 3 , 1.2m deep, the water is filtered with a 40-mesh net to prevent the invasion of harmful organisms. River sand or sea sand with a thickness of 10 cm and a particle size of 0.5 to 3.0 mm is laid on the bottom of the pool as the bottom sand, and spread on the bottom of the pool. The drainage pipe is arranged at a lower position at the bottom of the pool, and is arranged diagonally with the water inlet pipe. Leave 20-30 cm of blank space at the bottom of the pool on both sides of the water inlet pipe and the drain pipe without sanding, so that dirty water can flow away quickly when cleaning the sand surface.

[0018] 2. Pre-treatment of breeding: Disinfect the cement pool with commercially available bleach solution mixed with water, the dosage is 20ml per cubic water, rinse twice with tap water after disinfection, thoroughly rinse the disinfectant solution, and then dry it for 5 d...

Embodiment 2

[0027] Cement pool conditions: select 2 hard bottom square cement pools with an area of ​​15 m 3 , 1.2m deep, the water is filtered with a 40-mesh net to prevent the invasion of harmful organisms. The bottom of the pool is paved with river sand or sea sand with a thickness of 10 cm and a particle size of 0.5-3.0 mm, and spreads it flat on the bottom of the pool. The position of the drain pipe is low, and it is in a diagonal position with the water inlet pipe. Leave 20-30 cm of blank space at the bottom of the pool on both sides of the water inlet pipe and the drain pipe without sanding, so that dirty water can flow away quickly when cleaning the sand surface.

[0028] 2. Pre-treatment of breeding: Disinfect the cement pool with commercially available bleach solution mixed with water, the dosage is 20ml per cubic water, rinse twice with tap water after disinfection, thoroughly rinse the disinfectant solution, and then dry it for 5 days. Sow commercially available juvenile sea...

Abstract

The invention discloses a method for mixed culture of Holothuria scabra and Litopenaeus vannamei in an indoor pond. Technical measures including concrete pond conditions, culture pretreatment, larva stocking, bait casting, water quality control and disease control, Litopenaeus vannamei aftertreatment, Holothuria scabra aftertreatment and sediment treatment after culture are adopted according to biological characteristics of the Holothuria scabra and the Litopenaeus vannamei, and reasonable arrangement of larva specifications and larva casting time is combined with culture technologies of the Holothuria scabra and the Litopenaeus vannamei, so that ecologically complementary and mutually beneficial mixed culture of the Holothuria scabra and the Litopenaeus vannamei is achieved. The Holothuria scabra ingests organic matters and scraps decomposed by residual baits, metabolites of the Litopenaeus vannamei, microorganisms and bacteria, so that survival rates and growth speeds of the Holothuria scabra and the Litopenaeus vannamei are increased, and the Litopenaeus vannamei has a remarkable ecological effect on improvement in the water quality and sediments. The method for mixed culture of the Holothuria scabra and the Litopenaeus vannamei in the indoor pond is simple, convenient, efficient, highly operable and capable of improving the culture water quality and the sediments so as to achieve indoor efficient ecological culture of the Holothuria scabra and the Litopenaeus vannamei.

Description

technical field [0001] The invention relates to a method for polyculture of sea cucumber and whiteleg shrimp in an indoor pond, and belongs to the technical field of seawater culture. Background technique [0002] rough sea cucumber ( Holothuria scabra ), commonly known as "Arrhythmia", has high nutritional value and medicinal value, and is one of the more popular edible sea cucumbers in southern my country. It is a high-temperature-resistant, eurysalinous species that mainly uses organic matter in sediments as nutrients, and feeds on diatoms, bacteria, protozoa, cyanobacteria, foraminifera, and organic debris of animals and plants in the substrate. Typical sediment-feeding animals are cleaners of the marine environment. Sea cucumbers can accelerate the mineralization of sediments through strong feeding and bioturbation of sediments through burial, which is important for the stability of benthic habitat diversity. And the circulation of nutrients has a positive meaning. ...
