Embodiment 1

[0036] Oviposition substrate preparation: excavate pond mud, add tap water, stir, settle, remove duckweed and other floating matter, wrap it with 100-mesh nylon sieve, squeeze and sieve, remove snails, chironomus larvae and other benthic organisms and impurities , spread out to a thickness of 15mm, and dry in an oven at 120°C for 30min. Purchase commercially available ADA mud, pulverize it in a blender, filter through a 40-mesh nylon sieve, and pulverize what fails to filter. It is obtained by mixing 70wt% of the treated pond mud and the rest of the ADA mud powder.

[0037] Preparation of peat soil leaching solution: choose a large tank in advance, soak the peat soil in water, the weight ratio of peat soil to water is 1:5, soak for 1 month.

[0038] A glass tank with a length, width and height of 120 cm×60 cm×60 cm is selected as the spawning tank, and a 20-mesh nylon screen tulle bag with a length, width and height of 120 cm×60 cm×65 cm is placed inside the tank, which is ti...

[0042]Oviposition substrate preparation: excavate pond mud, add tap water, stir, settle, remove duckweed and other floating matter, wrap it with 100-mesh nylon sieve, squeeze and sieve, remove snails, chironomus larvae and other benthic organisms and impurities , spread out to a thickness of 15mm, and dry in an oven at 120°C for 30min. Purchase commercially available ADA mud, pulverize it in a blender, filter through a 40-mesh nylon sieve, and pulverize what fails to filter. It is obtained by mixing 65wt% of the treated pond mud and the rest of the ADA mud powder.

[0043] Preparation of peat soil leaching liquid: choose a large tank in advance, soak the peat soil in water, the weight ratio of peat soil to water is 1:4, and soak for 40 days.

[0044] Layout method of spawning tank: select a glass tank with a length, width and height of 100 cm × 55 cm × 55 cm as the spawning tank, and put a 20-mesh nylon mesh tulle bag with a length, width and height of 100 cm × 50 cm × 60 cm ...

Abstract

The invention relates to an arrangement method of an egg-laying tank, and discloses an arrangement method of an egg-laying tank for the breeding of blackfin pearlfish. The method comprises the following steps: 1) selecting a glass tank with an length-height-width size of (80-120) cm*(50-60) cm *(50-60) cm as an egg-laying tank; 2) placing a screen closely attached to the inner wall of the egg-laying tank into the egg-laying tank, wherein the screen has a corresponding size; 3) placing ferris-wheel-type egg-laying chambers which have a height lower than the height of the glass tank into the tank; 4) laying an egg-laying substrate with a thickness of 4 cm on the upper layer of the screen; 5) adding a peat soil leaching solution into the egg-laying tank, wherein the leaching solution immersesall the egg-laying chambers; and 6) arranging a filter at the upper end and the lower end of the egg-laying tank, and arranging a heating rod at the lower end. The invention solves the technical problems that the conventional killifish breeding work is complex, the breeding efficiency is low, the occupied space is large, and consequently the large-scale production cost is high, and provides a technical guarantee for the large-scale breeding of the ornamental fish.

Description

technical field [0001] The invention relates to a method for arranging a spawning tank, in particular to a method for arranging a spawning tank for black pearl killifish breeding. Background technique [0002] Black pearl killifish: scientific name: Austrolebias Nigripinnis (NGP), English name: BlackfinPearlfish, belongs to the South American annual killifish (Killifish), native to the Uruguay basin in South America, its colorful, is a famous tropical ornamental fish, belonging to small ornamental fish High-end varieties. The body length of the adult male ornamental fish is 4-6cm; the female individual is only 3-5cm. [0003] The traditional breeding method of this fish is loaded down with trivial details, and labor cost is high. Usually, sexually mature male and female broodstock are selected and raised separately in a breeding tank. A small pot (or small flower pot) filled with peat soil is placed in this tank. After the broodstock have spawned in the soil for several da...
