Abstract
The invention belongs to the field of aquaculture, and particularly relates to a method for culturing one-year patinopecten yesoensis. The method effectively avoids vigorous attachment periods of mussels, oysters and heterogeneous algae by one-time seedling separation and three-time cage inversion so as to improve the survival rate of seedlings; the quality and the specification of the seedlings are promoted by seedling selection; and the density is reasonably dispersed and the living space is expanded so as to facilitate the growth of the seedlings. The method is suitable for large-scale offshore culture, and has great significance for the development of the shell industry.
Description
Technical field
The invention belongs to aquaculture field, be specifically related to a kind of one age Patinopecten yessoensis cultural method.
Background technology
Patinopecten yessoensis originates in Japan and Far-east Area of Russia, is the cold water shellfish, and it is higher to be distributed in salinity, and the substrate that no fresh water injects is hard, and the few and depth of water of silt is no more than the littoral sea area of 40m.Be one of the improved seeds of the comparatively suitable artificial increasing cultivation of quality in world's Pectenidae, China introduces from Japan early 1980s, culture in sea areas such as main Liaodong Peninsula in northern China, chang-dao, growth rate is slower, begin to the high 11-12cm of shell from juvenile mollusk, the shortest time needs 1 year 07 months.According to record, maximum shell Gao Keda 27.94cm, its life-span was about 25 years.
In recent years because the expansion of scale is cultured in the surrounding area, Liaodong Peninsula, delicate variation has taken place in breeding environment, excessive breed has destroyed ecotope, and scallop begins to occur large quantities of phenomena of mortality, and Changhai County, Daliang City scallop lethality in 2007 is 70～90%; Reached 60%～90% in 2008.Therefore, be badly in need of the orderly development that a kind of good ecologic breeding pattern is taken whole industry at present, promote scallop culture health, orderly, permanent development.
At present, the breeding way of Patinopecten yessoensis mainly contains the end and broadcasts propagation (propagation of releasing) and suspended longline farming dual mode; Be suitable for Patinopecten yessoensis the release sea area of propagation substrate condition of water temperature condition and not being suitable for of growing for possessing, carry out floating raft type and hang down that to culture be the main mode that Patinopecten yessoensis is produced.It is a kind of cultural method that generally adopts in the present scallop culture that the lantern cylinder mould is cultured, and this breeding way capacity of anti-storm is strong, and water fills unobstructedly, and the scallop growth is fast, and the survival rate height is operated more conveniently, but one-time investment is big, and risk is very high.
Summary of the invention
The purpose of this invention is to provide a kind of standard, efficiently one age Patinopecten yessoensis suspended longline farming method, this method can reduce the influence of culturing environment, improve one age shellfish output.
Technical scheme of the present invention is: a kind of cultural method of Patinopecten yessoensis, this method be at greater coasting area, adopts the floating raft type cylinder mould to culture, and described buoyant raft comprises at least two parallel floating well ropes, and floating well rope is provided with float, is connected with buoyant rope between buoyancy and the floating well rope.Breeding cage is hung on floating well rope, and Patinopecten yessoensis is in breeding cage, and concrete steps are as follows:
(1) reaches 17 ℃～20 ℃ in water temperature every year, the Patinopecten yessoensis seed of screening shell height more than 0.5cm put breeding cage into, put 150 pieces of Patinopecten yessoensis seedlings in every layer of breeding cage, breeding cage is hung on by the 70-90cm spacing distance and is provided with on the afloat floating well rope, and breeding cage is put in a suitable place to breed in the dark seawater of 5-8m;
(2) be lower than 23 ℃ in water temperature, the seed shell is tall and big to be accounted for more than 80% in 1.5cm, and the monitoring mussel adheres to the peak period and falls later cage, seed is cleared from former breeding cage, filter out the tall and big Patinopecten yessoensis seed of shell and advance cage in 1.5cm, the evacuation of falling cage density, breeding cage layer loading amount is 40-50 piece;
(3) water temperature is below 18 ℃, the seed shell is tall and big to be accounted for more than 70% in 3.5cm, assorted algae, assorted shellfishes such as sea leaf mustard, oyster adhere to the peak period phase and fall cage later, filter out the tall and big Patinopecten yessoensis seed of shell and advance cage in 3.5cm, the evacuation of falling cage density, breeding cage layer loading amount is 18-25 piece, seam cage line is wanted more than 18 strands, every layer of 2-3 pin, one age shellfish advance in the cage process to grasp the growing state of seed at any time, but advance cage 3.5-3.8cm advance cage early stage, and the later stage transfers to more than the 4.0cm on suitably according to seed growing way situation;
(4) the Patinopecten yessoensis seedling is through the high-speed rapid growth in a winter, and reach 2 ℃ or more in water temperature next year, and temperature reaches more than 0 ℃, continue to evacuate density and falls cage, and the tall and big Patinopecten yessoensis seed in 5.0cm of screening shell advances cage, and the layer loading amount of breeding cage is 15-18 piece;
(5) the Patinopecten yessoensis shell is tall and big accounts for 95% and begins results when above more than 6.0cm.
Cylinder mould in the breeding process is according to the seawater velocity situation, select the cylinder mould of different mesh, seawater velocity is greater than the sea area of 1.5km/h, select the little mesh cylinder mould of 1.0/1.5/0.5cm, reduce the influence of flowing water to seed, seawater velocity is selected the mesh cylinder mould of 1.5/2.0cm less than the sea area of 1.5km/h, increase the permeable of cylinder mould, increase the filter appetite of scallop.
Distance between the described parallel floating well rope is 8-10m.
Culture float and will use rationally,, increase float at any time, connect the long 30-350cm of being of buoyant rope of float and floating well rope according to raft weight, float stressing conditions.
Described breeding cage is 20 layers, and every layer height is 13-15cm, and the diameter of breeding cage is 32-34cm.
The invention has the beneficial effects as follows: by once dividing seedling, fall cage for three times, effectively avoided adhering to the Sheng phase of mussel, oyster, assorted algae, improve weed survival rate; By the seed seed selection, promote seed quality and specification; Rationally evacuate density, explore more opportunity for survival, be beneficial to the seed growth.The present invention is applicable to the breed of big standard coastal waters, is significant for the shellfish industry development.
