Description
Technical Field
The invention relates to the technical field of oyster cultivation, in particular to a cage hanging cultivation method for monomeric oyster fries.
Background
In the traditional cultivation process of the monomeric oyster fries, 1-3cm fries are thin in shells, small in size and fragile, and hung in a cultivation cage in a high-flow-rate sea area (with the flow rate of more than 3 knots) and can move back and forth due to water flow impact, so that most shells of the fries are broken, the death rate is high (about 50%), and therefore the fries can only be temporarily cultivated in a low-flow-rate and gentle sea area. The oyster fries need abundant algae in water as baits for growth, and the flow rate is slow, the baits are lacked when the water body is updated slowly, and the growth speed is slow. And the fries are stacked and extruded in each layer in the cage body, so that the shape of partial shells of the fries is poor, and the sale quality of the finished oysters at the later stage is influenced. Meanwhile, after the traditional oyster fries grow, the traditional oyster fries need to be transferred from a small-mesh (1.0cm) cultivation cage to a large-mesh (3.8-4.0cm) cultivation cage, the operation of the method needs to purchase cultivation cages with two specifications, and needs to be manually poured twice a year, dead oysters and impurities need to be manually sorted in the manual pouring process, and the process can cause certain damage to normal oyster shells (the oysters can die later, so that the survival rate is low), and a large amount of manpower and material resources are needed, so that the labor cost and the oyster fries cost are high.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the defects of the prior art are overcome, the cage hanging cultivation method of the monomeric oyster fries is provided, the bottleneck problem that the monomeric oyster fries cannot be hung in a cage for cultivation in a high-flow-rate sea area is solved, the mortality rate of the same number of oyster fries is greatly reduced, the mortality rate is reduced from about 50% to about 10%, and the cultivation cost of the oyster fries is saved.
The technical scheme of the invention is as follows:
the single oyster fry hanging cage cultivating process includes packing single oyster fry into small netted silk net bag with two ends sealed and wrapping oyster fry with silk net bag; putting the silk thread net bags into a multi-layer cultivation cage with a large mesh, putting one silk thread net bag in each layer, and hanging the cultivation cage in an open cultivation sea area; and (5) after the oyster fries grow to naturally break the silk net bags, carrying out cage-reversing hanging cultivation.
Preferably, the mesh of the wire mesh pack is 1.5-2.5 cm.
Preferably, the mesh of the multi-layer cultivation cage is 3.8-4.0 cm.
Preferably, the filling quantity of the monomer oyster fries in the silk net bag is as follows: 100 and 150 single oyster fries of 1-3cm are filled in a silk net bag of 20-25cm length. When the density is lower than the density, the volume ratio is firstly reduced, the volume of the silk thread net bag is reduced, the moving space in the cage layer is enlarged, the death rate is increased, and meanwhile, the tension required for breaking the silk thread net bag is difficult to achieve after the oysters grow.
Preferably, the layer height of the multi-layer cultivation cage is 20-30 cm.
Preferably, the number of layers of the multi-layer cultivation cage is 8-10.
Compared with the prior art, the invention has the following beneficial effects:
1. the breeding method solves the bottleneck problem that the single oyster fries can not be bred in cages in high-flow-rate sea areas, greatly reduces the death rate of the oyster fries with the same quantity, reduces the death rate from about 50 percent to about 10 percent, improves the survival rate of the fries, and saves the breeding cost of the oyster fries. In addition, the number of times of cage falling is reduced, and the specification of a single cage body is used, so that the related matched production cost and labor cost are reduced. And in the culture cage with the same specification, more oyster fries can be hung, the culture volume rate is improved, and the production efficiency is further improved.
2. In the culture process of the method, in the high-flow-rate sea area, the growth speed of the monomeric oyster fries is also high due to the fact that the water body is fast to update and the bait is sufficient, and compared with the monomeric oyster fries temporarily cultured in the low-flow-rate sea area, the growth speed is improved by 30% -50%.
3. According to the breeding method disclosed by the invention, oyster fries are restrained by the silk thread net bag, the activity space is reduced, the damage rate of oyster shells is reduced, the normal growth of the fries is ensured, the high-quality shell rate is high, and a foundation is laid for the later-stage high-sale quality of the oysters.
4. The culture method prolongs the cage turnover period from twice a year to three times a year, and only needs to use the culture cage with one specification, thereby saving the purchase cost and the labor cost of the high-price culture cage.
5. According to the invention, oyster fries are restrained by the silk net bag, friction damage to the oyster fries is reduced, meanwhile, the fry putting amount is increased, and in addition, the fry putting amount is increased, so that the movement space of the silk net bag on a cage layer can be reduced, and the collision death rate is reduced. Meanwhile, the silk thread net bag has flexible characteristics, can expand along with the growth of oyster fries, can not limit the forming of the shells of the fries while protecting the oyster fries, ensures that the shells are normal after the fries are normal, and lays a foundation for the sales link.
