A kind of Patinopecten yessoensis seed breeding device described in the utility model is done further combined with specific embodiments below
Detailed introduction, the technical solution of the utility model include but is not limited to following embodiment.
Conventional chambers seedling method is mainly larvae-rearing at present, and the time is mainly 1 annual~March, in nursery, there is liter
Temperature changes water and falls the processes such as pond, inflation, bait throwing in, and cost mainly has water, electricity, bait and labour cost, wherein the water of nursery stage, electricity
Expense accounts for the 50~60% of total cost, and since nursery is just worth around the Spring Festival, labour cost is higher, also accounts for 30% or so.It rises
The second level seedling price that warm seedling method is brought out is in 0.02 yuan/or so.And the method that the utility model uses, due to not needing to rise
Temperature without bait throwing in, in 4, May starts to breed, and labo r usage is few, initial estimate second level seedling price in 0.01 yuan/or so, at
It is substantially reduced on this.Since breeding device provided by the utility model can use in its natural state, early period proof strength it is high,
Later period high survival rate, without using any drug in entire reproductive process, quality is also obtained far better than indoor larvae-rearing
Obtain seed.
Embodiment
By seedling rearing room breeding indoors, through choosing the spat young of excellent D-shaped larval phase according to 1/mL concentration launch
In scallop seed breeding device, whole process need to be monitored and measure to the growing state of the spat young, to the spat young
Average size is greater than 250 μm, when the ratio for the eyespot young occur accounts for 5~10%, launches adhesion bag.The long data of young shell such as Fig. 4
It is shown.
Since the timing launching the spat young, test monitoring data is as shown in table 1 before launching adhesion bag:
Spat young density and distribution in net cage before the dispensing adhesion bag of table 1
From Fig. 4 and table 1: showing that seedling is being grown always, seedling is concentrated mainly on upper layer, and as time goes by, part
The young is dead, and what is remained is all the strong spat of viability, realizes high-intensitive screening.
Second stage attachment
Each breeding net cage launches 25 string adhesion bags, and the total length of every string adhesion bag is 3m.
Find by monitoring: the spat young is more to adhere at the middle and upper levels, and bottom attachment is less.
Since method for culturing seedlings of the invention puts into the D-shaped young in net cage, there are the physical factors such as wave, ocean current, water temperature
The reason of effect, there are also bait competitions, the survival of the fittest, what is remained is all high-quality seed, so proof strength is high, it is preceding
The high-intensitive screening of phase, makes later period high survival rate.The survival rate of the seed second level seedling of conventional larvae-rearing is 30% or so, and this
The survival rate of the seed second level seedling of invention can reach 80% or so, and (this test is bred as about 26.6 ten thousand pieces of second level seedling altogether, and survival is about
220000 pieces).And without using any drug in entire reproductive process, quality is also far better than the obtained seedling of indoor larvae-rearing
Kind.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
