Continue to move about toward fish channel direction is crossed, thus by fish channel swim in network access case naturally, be hung on drawstring in net cage Enteromorpha,
Sargassum, fragrant plant mentioned in ancient texts, sea grape and feed packet, the macula lutea basket fish of seedling is received in trapping naturally to be able to domestication simultaneously in net cage
Raising；
(4) cage culture daily management
When the density of the macula lutea basket fish of trapping network access case reaches 30-40kg/ cubes of water body, the cylinder mould of macula lutea basket fish will be traped
It removes, and fish channel will be crossed and tied up on net cage frame far from one end pull-out water surface of net cage, or fish channel rope is beaten
Knot does not allow macula lutea basket fish in net cage to swim out of net cage, starts simultaneously at and carries out daily cultivation pipe to the macula lutea basket fish traped in net cage
Reason:
1. bait throwing in management
According to ingest characteristic and the cage culture environment of macula lutea basket fish, little particle buoyancy feedstuff feeding, the feeding of selection are selected
Protein content is 25%-30% in material, early, middle and late daily respectively to feed once, feeds daily and follows periodically, is quantitative, determining matter principle,
Day feeding volume is 5% ~ 7% of macula lutea basket fish total weight in net cage, arrests the measurement of 3-5 tail macula lutea basket fish at random simultaneously every 7 days
Record that body is long and weight, as the foundation of adjustment feeding volume, 2 hours surplus material situations after specific feeding volume is fed according to upper one,
Water flow, stormy waves size, water temperature and water clarity height are adjusted, while Enteromorpha, sargassum, fragrant plant mentioned in ancient texts or sea are hung in net cage
Grape, routine observation, above-mentioned seaweed are mended in time after being eaten up and hang；
2. water quality is observed
Daily monitoring usually mainly measures water Inversion phenomenon, dissolved oxygen, pH and the turbidity of caged-culture waters, after lasting heavy rain,
The silt and fresh water of land largely pour marine, will cause coastal seawater salinity altercation and muddiness；After typhoon, due to wave
Increase seabed organic matter, will also result in seawater muddiness and nutriment increases, need algae phase change in close observation seawater, in advance
The preparation of prevention breakout of red tide is carried out, typhoon and rainstorm weather, stopping in 1 day in advance feed feed, replace and increase extra large in net cage
Algae veil, reduce extreme weather in net cage macula lutea basket fish stress；
3. periodically inspection
When feeding daily, record of patrol, essential record water temperature, dissolved oxygen, transparency, pH, fish are carried out to each cage culture situation
Activity, situation of ingesting and sick fish and dead fish situation；Meanwhile whether there is or not breakages for inspection net cage frame, etting and anchor chain structure, avoid
The macula lutea basket fish escape cultivated in net cage；
4. disease prevention and control
Common disease has enteritis, vibriosis and virus infection during macula lutea basket fish culture, when disease occurs in macula lutea basket fish
When state, disease type is promptly and accurately determined by examining, comparing fish disease data and consulting fish disease expert first, finds disease accurately
Cause, macula lutea basket fish suffer from enteritis and vibriosis early period, and fresh garlic is added in feed and feeds and pay attention to material controlling, can be effectively controlled
Progression of the disease；Macula lutea basket fish passes through improvement breeding ecological environment after infecting irido virus, increases fish body autoimmunity and carries out
Prevention and control reduce or stop feeding for feed during one's sickness；
5. wheel is caught wheel and is sold
It catches and grabs the tall and big macula lutea basket fish in 7cm of body in net cage and sold；Wherein,
The fish channel of crossing is netted channel, and the netted channel interior is equipped with the screw support rack of stainless steel or plastic material,
The screw support rack is close to the netted vias inner walls；The fish channel of crossing is perpendicular to the net cage and the cylinder mould line
Cross section is round or rectangular；It is described cross fish channel perpendicular to the net cage and the cylinder mould line cross-sectional area by described
Cylinder mould one end gradually becomes smaller to described net cage one end.
2. as described in claim 1 trap the method received seedling and cultivate macula lutea basket fish, which is characterized in that on the food calling platform
Equipped with elastic stainless steel item or clip to fixed bait.
3. as claimed in claim 2 trap the method received seedling and cultivate macula lutea basket fish, which is characterized in that described into fish channel
Height be the cylinder mould height 1/3 to 1/2.
