Description

The cultural method of sweetfish

Technical field

The present invention relates to the cultural method of a kind of sweetfish.

Background technology

Sweetfish is a kind of peculiar, famous and precious fresh-water fishes of Nanxijiang river, long 15 to 20 centimetres of body, one heavily about three liang to about half jin.Nanxijiang river abounds with sweetfish, for a long time well-known.As far back as between Ming Dynasty's year in Wanli year, Nanxijiang river just produces sweetfish.Record according to bright Wanli year " mansion, Wenzhou will ", sweetfish " long three or four cun, taste is good and without raw meat, raw clear stream only October time have, with happy produces different less "." Wild Goose and Reed Marsh Mountains will " carries again: " all water institutes of swinging enter to locate all have it, swing water west and flow Nan Xi forever, then also have it from maple woods, shelves small stream, Xia Tan, ancient temple pool Zhu Chu." sweetfish is commonly called as " small stream carp " and also cries melon fish, is subordinate to salmon shape order pawl fish suborder recklessly, sweetfish and gaining the name.Fragrant fish length and flat-sided, a little point of chewing, body drapes over one's shoulders thin squama, and back is greyish black, belly silvery white, oppresses delicate greasiness, delicious and savory, and being first-class food fish, is famous and precious economic fish, have the good reputation of " kings of fresh-water fishes ".。Therefore, farmers', in aquaculture structural adjustment, makes full use of the waters such as pond, reservoir development mullet breeding prospect wide.

Summary of the invention

The object of the present invention is to provide to have and reduce aquaculture cost, improve the productive profit of raiser, shorten the cultural method of a kind of sweetfish of the advantages such as cultivation cycle.

Technical scheme of the present invention is: the cultural method of a kind of sweetfish, and the step of the cultural method of described sweetfish comprises:

(1) pond is selected: fishpond is neglected greatly water source and the water yield and determine, and each fishpond is suitable with 100-300 square metres, and pool wall thickness should be 15 centimetres, depth of water 60-90 centimetre, at the bottom of pond and pool wall stone or concrete be built into;

(2) seed is put in a suitable place to breed: fry body length is advisable with 3-4 centimetre, put season in a suitable place to breed April, it is 100 ~ 300 tails/every square metre that seed is put in rectangle pond in a suitable place to breed, circular pond be 200 ~ 400 tails/square metre, these ponds are except employing continuous-flow type intensive culture, day and night must start aerator, continuous oxygenation, the survival rate of guarantee fry, before fry enters pond, first need carry out dipping sterilization, bring fishpond into bacteriological protection;

(3) feed management: the breeding density of number of times Main Basis fry of throwing something and feeding, the environmental factor such as developmental stage and water temperature, water quality and the water yield and determining, sweetfish is larger in morning, late food ration according to observations, therefore should throw mixed bait in morning, evening more, the daily ration, feeding quantity of mixed bait is sufficient at dissolved oxygen, water temperature is 20% of fish body weight when 17-22 degree Celsius, if temperature lower than 17 degrees Celsius and dissolved oxygen amount is lower time should reduce feeding volume;

(4) daily management: adhere to sooner or later patrolling the pool, keep water quality pure and fresh, in good time start oxygenation, ensure that the water-soluble oxygen amount in pond often rises more than 4 milligrams, meet abnormal weather and will prevent the general pool of anoxic especially, splash the change of pond water temperature, sweetfish ingests when water temperature less than 10 DEG C or more than 27 DEG C minimizing, growth weakens, and even stagnates, and water temperature more than 30 DEG C stops ingesting completely, do not ingest to water temperature 33 DEG C and lethally to die, at high temperature season, when water temperature is more than 26 DEG C, then cooling measure should be taked, as taken sunshade or the low reservoir water of filling water temperature or spring.

In a preferred embodiment of the present invention, described mixed bait is fish meal, animal albumen powder, chicken meal, dregs of beans, rice bran, pale reddish brown first Mu, vinasse, vitamin and inorganic salt mixt, solid fat, grits.

In a preferred embodiment of the present invention, each Ingredients Weight of described mixed bait is that fish meal accounts for 33%, animal albumen powder accounts for 5%, chicken meal accounts for 4%, dregs of beans accounts for 10%, rice bran accounts for 15%, pale reddish brown first Mu accounts for 5%, vinasse account for 8%, vitamin and inorganic salt mixt account for 4%, solid fat accounts for 6%, grits account for 10%.

The cultural method of a kind of sweetfish of the present invention, has and reduces aquaculture cost, improves the productive profit of raiser, shortens the advantages such as cultivation cycle.

Embodiment

Be described in detail below in conjunction with to preferred embodiment of the present invention, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.

In one embodiment, the cultural method of a kind of sweetfish, the step of the cultural method of described sweetfish comprises:

Further illustrate, described mixed bait is fish meal, animal albumen powder, chicken meal, dregs of beans, rice bran, pale reddish brown first Mu, vinasse, vitamin and inorganic salt mixt, solid fat, grits, and each Ingredients Weight of described mixed bait is that fish meal accounts for 33%, animal albumen powder accounts for 5%, chicken meal accounts for 4%, dregs of beans accounts for 10%, rice bran accounts for 15%, pale reddish brown first Mu accounts for 5%, vinasse account for 8%, vitamin and inorganic salt mixt account for 4%, solid fat accounts for 6%, grits account for 10%.

Further illustrating, aquaculture management: (1) fry put in a suitable place to breed before preparation: should check before putting in a suitable place to breed, keep in repair every facility, and within first about 15 days, intake in advance putting seedling, after making pool wall cover with diatom, put seedling again.(2) seed is chosen and transport: sweetfish is a rare variety, artificial seed at present only in Zhejiang, Hebei etc. several nursery on sale.Seed transport automobile can be adopted to transport for long-distance, during water temperature 17-19 degree Celsius, density be 7-8 tails/liter, after 7-8 hours, survival rate can reach more than 98%; Short-distance transport density can strengthen.(3) fry puts the management at initial stage in a suitable place to breed: fry, before putting fishpond into, first must carry out dipping sterilization, in order to avoid bring germ into growing pond, dipping antibiotic dosage is about 1,/50,000 one 1,/10 ten thousand of the water yield.Put the same day in a suitable place to breed just can bait throwing in, daily ration, feeding quantity is depending on the health condition of fry and weather, and after in a few days, daily ration, feeding quantity progressively brings up to about 15%.(4) management is formed: the fry generally putting body weight 5-6 gram in mid-March in a suitable place to breed, just can reach commercial specification to early June.The feed coefficient of sweetfish is 2.5-3.Form main attention the following aspects: a in management, throw something and feed more fresh, be of high nutritive value and be rich in the bait of animal protein, to produce the business compared with large gauge; The change of b, often attention water temperature, sweetfish is not low temperature resistant, when water temperature is lower, easily causes indigestion, can bring up to optimum water temperature or increase bait throwing in material, but avoid fatty more bait of throwing something and feeding when having ready conditions; C, according to our observation, sweetfish also kills and devour mutually sometimes, so often will patrol pond, observes ingesting and active situation, to adjust daily ration, feeding quantity in time of sweetfish; D, often observe the whether normal and appetite change of the activity of fish in pond.Inspection has disease-free generation, in order to avoid cause damage.The invention provides the cultural method of a kind of sweetfish, have and reduce aquaculture cost, improve the productive profit of raiser, shorten the advantages such as cultivation cycle.
