Abstract

The invention discloses a kind of cage culture method of Scioenops ocellatus, including net cage, fingerling dispensing, bait preparing, four steps of nursing and management are set.Net cage is set in suitable sea area, the fingerling of health is chosen, by 150~200 tails/m3Density deliver, be that primary raw material prepares bait with small fish, small shrimpses, daily right place feeds bait, and strengthens prevention from suffering from the diseases and work.This method exchanges high-grade aquatic products for using the characteristics of Scioenops ocellatus feeding habits are extensive, premunition is strong with the food of low-quality, and focuses on the prevention work of disease in breeding process, substantially increases the survival rate and yield of fingerling.

Description

A kind of cage culture method of Scioenops ocellatus
Technical field
The present invention relates to field of marine aquaculture, the cage culture method of particularly a kind of Scioenops ocellatus.
Background technology
Sea-farming is using shallow sea, beach, bay, encloses the marine sites such as the pool and raised and bred marine products Economic animals and plants The mode of production, is that mankind's orientation utilizes one of living marine resources, the important channel of Development of Marine aquatic products industry, and sea-farming is water The important component of industry.Scioenops ocellatus, scientific name sciaenops ocellatus, also known as red bulging fish, Scinenops ocellata, spot tail perch, Atlantic Ocean sheepshead, straits perch, blackspot sheepshead etc., lipid content is low, category high protein and low fat, low specific energy values fish, muscle amino Acid content belongs to medium level compared with other economic fish.The content of essential amino acid is low and scarce sulfur-containing amino acid, is non-fully Albumen, its delicious amino acid percentage composition is high compared with other fish.And Scioenops ocellatus are individual greatly, yield is high, economic benefit is good, are adapted to Large-scale cultivation.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of Scioenops ocellatus that can improve yield Cage culture method.
In order to achieve the above object, the technical scheme that the present invention is provided is as follows:
A kind of cage culture method of Scioenops ocellatus, comprises the following steps:
1) net cage is set:
Selection substrate is silt or husky mud bottom, and water quality is clear, pollution-free, sea area flow velocity within 1m/s, the sea without swirling flow Area, it is desirable to which at 10~32 DEG C, in 6~12m, net cage depth is the half of the sea area depth of water to the sea area depth of water to water temperature excursion;Net cage Specification is 3~6x3~6x3~6m, and mesh size is 0.8~1.2cm;The installation of completion net cage in 7~10 days before fingerling cartonning Work, and aerator is installed simultaneously;Scioenops ocellatus lower oxygen concentration resistance, but it is rapid and active to swim, and need to observe dissolved oxygen in water, works as dissolved oxygen Oxygenation operation need to be carried out when amount is less than 2.5mg/L;
5) fingerling is delivered:
In 5~June, 4.5~6cm of selection is long, body surface is bright and clean, scale is complete, the fingerling without disability, and fresh water is used before cartonning Cleaning 5~10 minutes, while attention avoids fish body of damaging, can put into net cage after cleaning, dispensings density for 150~200 tails/ m3, Scioenops ocellatus dorsal fin is undeveloped, easily escapes, therefore mesh is smaller than common fingerling, and being cleaned with fresh water before cartonning to prevent The adaptability of the new environment of disease and enhancing fingerling pair;
6) bait preparing:
Fresh small fish, small shrimpses are taken, after being shredded through bait machine, per kilogram is mixed into that 2~3g dusty yeasts are well mixed to be obtained Bait;Or freezing fishes and shrimps are taken, and cleaned up with seawater after defrosting, after being shredded through bait machine, per kilogram is mixed into 1g dusty yeasts and 40 Bait is obtained after~50g powdered glucoses are well mixed;10~15g Chinese medicines are added in the above-mentioned bait of per kilogram every two weeks Powder;Traditional Chinese medicine powder is added to primarily serve strengthen immunity, prophylactic effect;
7) feed and management:
1~5 day after fingerling dispensing, day feeding volume is the 1~2% of fish body weight, observes the food-intake of fish, if feed every time Without residue, day feeding volume increases to the 5~10% of fish body weight to bait;Fingerling is off one's feed before shaking down, if feeding Many influence water quality;Feed 3 times daily, each feeding volume is respectively 50%, 40%, the 10% of day feeding volume;First fed when feeding The 60% of each feeding volume, during remaining bait slowly is put into water when the remaining deficiency half of bait in net cage, first feeds one Part, the strongr more sensitive shoal of fish of reaction of body slowly puts into remaining bait again after taking food in advance, prevents more small and weak fish Group cannot eat food;
With growing up for fish body, once net is changed within 18~20 days, mesh size increases by 0.3~0.5cm every time, is washed every 7-10 days Etting of brush, it is ensured that seawater circulation amount and dissolved oxygen amount in net cage;Fish body is embathed with fresh water once, every time leaching during each draping Wash in operation, action is rapid, should handle with care, forbids mechanical damage, can effectively strengthen fish resistance prevention disease.
Preferably, the traditional Chinese medicine powder is to grind to obtain after the weight such as cloves, fennel seeds, scutellaria, dandelion mix.
Preferably, step 4) in the daily time for feeding bait be respectively 6:00~7:00、15:00~16:00、18:00 ~19:00.
Preferably, step 4) in it is daily feed bait feed an all same.
Preferably, in the small fish be free of ooze loach, ooze loach containing grease it is high, it is nondigestible, fish food after easily oil and Suffer from enteritis disease.
Beneficial effects of the present invention:The cage culture method of a kind of Scioenops ocellatus of the invention, with the small fish of low cost Small shrimpses are bait, strict control feeding volume and feeding method, using Scioenops ocellatus feeding habits it is extensive, premunition is strong the characteristics of, with The food of low-quality exchanges the aquatic products of top grade for, and focuses on the prevention work of disease in breeding process, substantially increases fingerling Survival rate and yield.
Specific embodiment
The following specific embodiments are described below is described in further detail to the present invention.
Embodiment 1
