Embodiment 1

[0013] A seawater pond fish and shellfish mixed culture mode, is realized through the following steps:

[0014] (1) Pond selection: select a pollution-free pond in the coastal area of ​​Ningde City, and test the water quality to meet the water standard for mariculture, with a salinity of 8-32‰, a water temperature of 12-30°C, and sufficient fresh water sources;

[0015] (2) Breeding species and quantity: 800 large yellow croakers / mu of more than 700g / tail are cultured in ponds, of which 100 large yellow croakers / mu of 700-800g / tail, 300 large yellow croakers / tail of 800-900g / tail, 900g / mu 400 large yellow croakers / mu with more than one tail, 20 mullet / mu with 300-500g / tail, 1kg / mu cockle seedlings with a shell length of 1mm;

[0016] (3) Management during the breeding period: when the water temperature is higher than 20°C, feed the pelleted feed at 4% to 5% of the weight of the cultured large yellow croaker. When the water temperature is 15-20°C, 2% to 4% of the weight of the...

Embodiment 2

[0019] A seawater pond fish and shellfish mixed culture mode, is realized through the following steps:

[0020] (1) Pond selection: Choose a pollution-free pond in the offshore area of ​​Fuding, test the water quality to meet the water standard for mariculture, with a salinity of 8-32‰, a water temperature of 12-30°C, and sufficient fresh water sources;

[0021] (2) Breeding species and quantity: 800 large yellow croakers / mu of more than 700g / tail in ponds, of which 200 large yellow croakers / mu of 700-800g / tail, 200 large yellow croakers / tail of 800-900g / tail, 900g / mu 400 large yellow croakers / mu with more than one tail, 20 mullet / mu with 300-500g / tail, 1kg / mu cockle seedlings with a shell length of 1mm;

[0022] (3) Management during the breeding period: when the water temperature is higher than 20°C, feed the pelleted feed at 4% to 5% of the weight of the cultured large yellow croaker. When the water temperature is 15-20°C, 2% to 4% of the weight of the cultured large yello...

Abstract

The invention discloses a mixed aquaculture mode for fishes and shellfish in a seawater pond and relates to the technical field of aquaculture. The mixed aquaculture mode is realized through steps of pond selection, aquaculture variety and number selection, aquaculture management and pond water management. According to the mixed aquaculture mode for fishes and shellfish in the seawater pond, mixed aquaculture is carried out on large yellow croaker and Chinese razor clam, and moreover, filter feeding mullet and bottom shellfish are cultured together, the aquaculture capacity is completely used, water full of fertilizer generated by the large yellow croaker aquaculture serves as the bait of the Chinese razor clam, the water full of fertilizer is discharged after the Chinese razor clam completely absorbs the alga therein, the multi-level large yellow croaker bait nutrition absorption and use are realized, the spending on the purchase of fertilizer for the Chinese razor clam is saved, and the rich nutrition level of the discharged water is greatly reduced; fresh water is continuously filled into the pond to lower the salinity, the white-spot disease of the large yellow croaker is effectively avoided, the large yellow croaker and Chinese razor clam benefit from each other, and the mixed aquaculture mode is an effective and energy-saving aquaculture mode.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a seawater pond fish and shellfish mixed culture mode. Background technique [0002] Mixed farming is a new type of farming mode, that is, two or more types of aquaculture are raised together, and the aquatic products coexist in a mutually beneficial manner to achieve better farming effects and obtain greater farming benefits. The invention patent with the application number 200610135254.X discloses a method for cultivating organic blue crabs. The culture mode adopted is mixed culture, and at least one of single species such as mud crabs and prawns, mullet, razor clams, and Gracilaria is mixed. The polyculture is carried out at least twice a year; the invention patent with the application number 201410422024.6 discloses an inland breeding method of large yellow croaker, which adopts a three-level salt reduction method to make the large yellow croaker reach full freshness bree...
