Embodiment 1

[0024] A method for artificially cultivating rust-spotted catfish indoors, comprising the following steps:

[0025] (1) Breeding pond preparation:

[0026] In the cultivation pond, the length is 5m, the width is 3m, and the depth is 1.5m. There are 15 air stones (full corundum air stones (40*40*4) from Fengxin Hengan Air Stone Co., Ltd.) to make the dissolved oxygen more than 4mg / L. After disinfecting with 30mg / L potassium permanganate for 3 hours, clean the pool wall. Inject fresh sand to filter seawater, and the water level is 80cm. The water temperature in the cultivation workshop is 28.5°C, and the seawater salinity is 30°C. At the same time, 5mg / L of EDTA was applied, and the density of Monocellular algae was added to 130,000 / m 3 The water body makes the water body appear slightly green.

[0027] (2) Larvae hatch into the pond

[0028] The heartbeat of the embryo reaches 150 beats / min and the oviposit crab is removed to a volume of 0.6m 3 Hatch bucket. Put 1 egg-be...

Abstract

The invention relates to an artificial indoor seedling breeding method for charybdis feriatus and belongs to field of charybdis feriatus cultivation. The method comprises the following three steps: preparing a breeding pond; hatching larvae, and putting the larvae into the pond; breeding seedlings. By taking the technical measures of water quality regulation, water temperature regulation, salinity regulation, illumination regulation, bait reinforcement and the like in the indoor breeding pond, artificial indoor seedling breeding is carried out on the charybdis feriatus. The artificial indoor seedling breeding method for the charybdis feriatus has the technical advantages that the specification of the seedlings is neat, the survival rate is high, and the vitality is high; the technology is mature, safe and easy to master, can be quickly absorbed and mastered by farmers, and is applied to development of large-scale artificial seedling breeding; the healthy and quick development of national artificial seedling breeding jobs for the charybdis feriatus is facilitated prospectively.

Description

technical field [0001] The invention belongs to the field of rust-spotted catfish culture, and in particular relates to a method for artificial indoor seedling cultivation of rust-spotted catfish. Background technique [0002] Charybdis feriatus is a large seawater crab with high economic value. It is mainly distributed in the southern part of the East China Sea and the South China Sea in China. Rust-spotted catfish has delicious meat, good taste, large individual, bright red and festive color, and high nutritional value. It is regarded as a high-end sea treasure, and its market price has always remained high. Rust spotted crab is one of the four most suitable economical crab species in the Western Pacific-Indian Ocean. At present, most of the commercial crabs sold on the market come from natural sea areas, and there are few artificially cultivated commercial crabs. Due to overfishing and changes in the seawater environment, the wild resources of rusty spotted catfish have...
