Abstract

The invention discloses a method for breeding puffer. The method specifically comprises the steps that a bulldozer is used for pushing sludge at the bottom of a pond onto the basic plane or enabling the sludge to be flushed out of the pond, and the pond is sterilized and disinfected; after the pond is cleaned and the pest removing is achieved, chicken manure used in per mu of the pond is mixed with quick lime to be fermented; single-cell plants are planted in the pond; during the fry throwing process, bighead carps, sea eels, soft-shelled turtles, giant freshwater prawns, South America white shrimps and the like are bred in the pond in a mixed mode; at the fry breeding stage, planktons and limnodrilus hoffmeisteri are mainly fed; after the puffer grows to 2 centimeters, puffer is fed with breaking food baits; farmers patrol the pond one time in the morning and one time in the evening; appropriate bait is thrown to feed the puffer, and the number of times of bait throwing and the bait throwing quantity are determined. By means of the method, the mixed raising method is adopted through the method for breeding the puffer, the yield of the buffer is increased, the meat quality of the puffer is increased, other aquatic products can be bred, and the profit of farmers is greatly increased.

Description

The cultural method of a kind of filefish

Technical field

The present invention relates to aquaculture field, relate in particular to the cultural method of a kind of filefish.

Background technology

Filefish belongs to globefish shape order, globefish suborder, platanistidae in classification, globefish belongs to, and this genus economic worth is very high, and kind and quantity are also more, each coastal distribution that all has in China, Korea, Japan and other Southeast Asia, the Huanghai Sea, the Bohai Sea and the East Sea are one of filefish kind and the maximum sea area of quantity in the world.

What inhabit the Huanghai Sea and the East Sea just has 15 kinds more than, especially in Middle of The Huanghai Sea and the north, as there is special filefish longline fishery in the marine sites such as the Changhai County From Zhangzi Islands China in the Rongcheng in Shandong, Liaoning, oceanic island and Wang Zong island, Zhuanghe county, the marine site such as off-lying sea, Yantai, oceanic island coastal waters that key operation fishing ground is Northern Huanghai Sea in history.The receipts phase is to being the Sheng phase at the beginning of 8 months at the beginning of 8 months, in 6 months in 5 months.In addition also there is, the double fishing industry of filefish in Hai Zhou gulf; There is the distribution of anadromous dark line globefish and fugu ocellatus globefish in THE LOWER YANGTZE VALLEY to river mouth.

Filefish is one of poisonous seafood fish, the internal organ such as its blood, liver, sexual gland and digestive tract contain severe toxicity, eating trace by mistake can make people poisoning fatal, but the muscle of filefish is nontoxic or containing micro-poison, as long as processing is proper, can make delicacy on seat, taste is very delicious, still state, Japan and Korea S are among the people is regarded as " first of hundred fishes ", and especially Japanese has a liking for food filefish when claiming the first in the world, and China also spreads the custom of " defy death and eat filefish " and says.

Filefish is except edible, and its tetraodotoxin " TTX " has very high medical value, is senior anodyne clinically, the effect regaining one's vigor in addition, and price is very expensive, and filefish micromicro is with process hides, so filefish whole body is precious, DEVELOPMENT PROSPECT is very wide.

summary of the invention

The technical problem that the present invention mainly solves is to provide the cultural method of a kind of filefish.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the cultural method of a kind of filefish, and concrete steps comprise:

1) in the winter time or arid season, mud at the bottom of the pool is pushed to basal plane or flushed out the pool with bulldozer, tan by the sun at the bottom of the pool 2～3 days to be full of cracks, remove humus, ammonia nitrogen, hydrogen sulphide and nitrous acid at the bottom of the pool, kill pathogenic bacteria and harmful organisms.Then pour into new water with 80 mesh filter screens to fish pond and reach 65 centimetres of degree of depth, every mu with 20 kilograms, bleaching powder or 70 kilograms of sterilizings of quicklime;

2), after cleaning up the pond and removing the evil, by 45 kilograms of mixed 15 kilograms of quicklimes fermentations of chicken manure for every mu of pool, in pond, make base manure with being hung in after 60 eyesight scholar mesh bag packing;

3) offer 1 aerator for average every 2 mu, and unicellular plant on planting in pond;

4) throw before seedling first with the anosis fry examination of a small amount of health of the same race water 1 day, determine water quality suitable after input in a large number again;

5) also can in pond, mix raising bighead, eel, soft-shelled turtle, Macrobrachium rosenbergii, Penaeus Vannmei etc.;

6) the fry phase is mainly fed its plankton and water silk earthworm;

7) grow into more than 2 centimetres after specification, feed its tame and docile bait material;

8) rain or shine sky, sooner or later respectively patrol the pool 1 time every day, observes activity and the situation of ingesting of filefish, to find in time fish disease or floating head phenomenon, measure water body physical and chemical factor as water temperature, dissolved oxygen, transparency etc., adjust in time, and carry out current entry, generally to change weekly 1～2 time water;

9) for fear of the appearance that mutually kills and devour phenomenon, must have and determine bait throwing in number of times and daily ration, feeding quantity in mind from the suitable bait of throwing something and feeding, fish body weight in 50 grams time one day 4 times, 50-100 gram time one day 3 times, 100 grams above one day twice, water temperature drops to 15 ℃ of food rations when following and reduces, and stops completely ingesting during lower than 10 ℃.

In a preferred embodiment of the present invention, the granular bait that the aquatic products such as the cuttlefish of described tame and docile bait material, shrimp, oyster, clam are made.

In a preferred embodiment of the present invention, the dissolved oxygen amount of described pond water is more than 4 mg/litre, pH value 7～8.5.

The invention has the beneficial effects as follows: the cultural method of a kind of filefish of the present invention adopts mixes the mode of raising, and has not only increased the output of filefish, has improved its meat, and can cultivate other aquatic products, has greatly increased raisers' profit.

Embodiment

Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.

The embodiment of the present invention comprises: the cultural method of a kind of filefish, and concrete steps comprise:

3) offer 1 aerator for average every 2 mu, and unicellular plant on planting in pond, it is more than 4 mg/litre keeping the dissolved oxygen amount of pond water, pH value 7～8.5;

6) the fry phase is mainly fed its plankton and water silk earthworm;

7) grow into more than 2 centimetres after specification, feed its granular bait made from aquatic products such as cuttlefish, shrimp, oyster, clams;

Compared with prior art, the cultural method of a kind of filefish of the present invention adopts mixes the mode of raising, and has not only increased the output of filefish, has improved its meat, and can cultivate other aquatic products, has greatly increased raisers' profit.

The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention to do, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
