A substrate suitable for breeding marine benthic aquatic animals

Abstract

The invention discloses substrate suitable for cultivation of marine benthonic aquatic animals. The substrate is made from, by weight, 50 to 70% of a component A, 20 to 40% of a component B and 20 to 40% of a component C; the component A is one of fine river sand, perlite, quartz sand and rock wool, having a particle size ranging from 3 micrometers to 2000 micrometers; the component B is one of bentonite, kaolin, clay and zeolite powder; the component C is one of rice husk charcoal, rice bran, peat and turf, powdered and having a particle size less than 1000 micrometers; the components are mixed according to the proportion and soaked in 20 to 35%. sea water, CaCO3 is added to adjust pH to 7.5 to 8.5 or so, and the substrate is obtained after ageing and removal of the aqueous part. The substrate has the advantages that materials are easy to obtain, operating is simple, the components are clear, and the substrate is suitable for lives of the marine benthonic animals and is environment friendly.

Description

[0001] Technical field: [0002] The invention belongs to the field of marine benthos breeding, and in particular relates to a substrate suitable for breeding marine benthic aquatic animals. [0003] Background technique: [0004] Marine benthic animals mainly refer to animals that inhabit the surface layer of the ocean base or in the sediment, and are an important part of the marine ecosystem. With the further increase of my country's marine development, marine environmental issues have attracted more and more attention, and most ports and bays have been polluted to varying degrees. At present, the plankton and swimming organisms that are mainly concentrated in the evaluation of the impact on marine environment organisms, as an important part of the marine ecosystem, the research on marine benthic organisms is still relatively lacking, especially the use of marine benthic organisms such as polychaetes and bivalves for biotoxicity assessment of marine sediments. Sediment has ...

Problems solved by technology

Due to the unclear background value of environmental pollution in the sea area, the matrix taken for domestication and control experiments may have been polluted. Even if the matrix has not been polluted, due to the difference in sampling time and location, the components of the sample will appear. difference

The complexity and uncertainty of this composition and the degree of contamination can greatly reduce the accuracy, reproducibility and reliability of test results.
