Abstract
The present invention proposes a kind of cultural method of fresh water perch, comprises the following steps:1) pond selection and processing:Scavenger pool shape rectangle, North and South direction, carried out disinfection with quick lime and use clear water service sink, pond spreads the thick pool mud of one layer of 30~40cm in bottom of pond, plants pasture and water above mud, place into the water of cleanliness without any pollution;2) pool water treatment:Water-quality control carries out between pH5~6.5 plus mixing liquid and draining, the mixing liquid is the filtrate after tealeaves, American aloe and dried orange peel boiling filtering cooling for 1~2 month before perch lists daily;3) perch is put in a suitable place to breed;4) feed is launched.The perch delicious flavour that this method obtains, protein content is high, and removes the mud taste of fresh water perch, reaches the requirement to process raw material.
Description
Technical field
The invention belongs to freshwater fish culturing technical field, and in particular to a kind of cultural method of fresh water perch.
Background technology
Perch it is Fresh & Tender in Texture, yellowish pink is pure white, nutritive value is high, be processing high level product quality raw materials.Perch is grown on
Sea water and fresh water boundary waters, it is a kind of fish that cultivation can be reversed with sea water and fresh water.In recent years, the perch seedling through desalination enters in freshwater ponds
Row large-scale cultivation succeeds, and turns into large freshwater aquiculture Quality and economy fish after Tilapia mossambica, turns into freshwater aquiculture
The main breed variety in region, freshwater aquiculture benefit is effectively improved, drive the development of Poor Mountainous Area culture fishery.
Mountain area freshwater aquiculture is mostly more original Ni Dichi, and the natural ecological environment in pond is good, and pond mud contains perch must
The various trace elements, association water earthworm, small fish and shrimp etc. of need swim to give birth to provides nutritional supplementation, the pool cultivated perch in mud bottom for perch
Have the advantages that the speed of growth is fast, sarcocyte is plump, mature stage is short.But the factor such as the soil property due to mud bottom pond, environment, water source, production
The perch gone out carries the distinctive mud taste of fresh-water fishes more, does not meet the requirement of processing of aquatic products raw material, turns into development freshwater aquiculture perch
The bottle diameter of fish industrialization.
It is grouper good appearance, delicious meat, nutritious, marketable fish can be both used as, ornamental fish can also be used as, it is wild
Raw grouper build is relatively small, obtains planktonic organism and the aquatic larva of insect as food to gnaw to be attached on cliff, it grows speed
Degree is slower, but lower oxygen concentration resistance, resistance against diseases are strong, if can be propagated artificially, it will bring larger economic benefit.
The content of the invention
The present invention proposes a kind of cultural method of fresh water perch, the perch delicious flavour that this method obtains, protein content
Height, and the mud taste of fresh water perch is removed, reach the requirement to process raw material.
The technical proposal of the invention is realized in this way:
A kind of cultural method of fresh water perch, comprises the following steps:
1) pond selection and processing:Pond shape rectangle, North and South direction, the depth in pond is 2.2~2.6 meters, in pond
The bottom on the pool is provided with water inlet pipe, and pond is carried out disinfection, and is carried out disinfection with quick lime and uses clear water service sink, in bottom of pond
The thick pool mud of one layer of 30~40cm is spread, pasture and water is planted above mud, places into the water of cleanliness without any pollution;
2) pool water treatment:Water-quality control is between pH 5~6.5,70~80cm of depth of water when fry is launched, then every 3~
5 days plus water once, every time plus 10~15cm of water, make the depth of water reach 180~200cm, and take float it is small enter, repeatedly change doing for water
Method regulates and controls water quality, carries out adding mixing liquid and draining daily within 1~2 month before perch lists, the mixing liquid is tealeaves, dragon
Tongue is blue and the filtrate after cooling is filtered in dried orange peel boiling;
3) perch is put in a suitable place to breed:The selection of perch seedling is healthy and strong, and body size is consistent, and length is in 4~5cm, every mu
1~20,000/tail is launched, fry is handled using 3~5wt% saline solutions irrigation and disinfection before lower pond, a little stone is suitably put in a suitable place to breed in pond
Spot fish is raised together together, and breeding density is 5~10kg/ mus;
4) feed is launched:Man-made feeds are launched, the day feeding volume of man-made feeds accounts for the 0.1~0.8% of total fish weight, the people
Work feed is mainly prepared from the following raw materials in parts by weight:40~50 parts of fishbone dust, 4~8 parts of spirulina polysaccharide extract, dregs of beans

Native filter and cardboard filter carry out filter at low temperature, obtain filtrate, added into filtrate spirulina polysaccharide extract with it is micro
Element, then Granulating process.
Beneficial effects of the present invention:
1st, carry out adding mixing liquid and draining daily within 1~2 month before perch lists, the mixing liquid is tealeaves, dragon
Tongue is blue and the filtrate after cooling is filtered in dried orange peel boiling, can not only effectively remove the mud taste of perch, and mud fishy smell is removed and basically reached
More than 90%, it is protein to also help it by adipose conversion, additionally it is possible to improves the anti-oxidant and anti-disease effect of fish itself.
2nd, the man-made feeds palatability used in breeding process of the present invention is good, is advantageous to the mixed breeding of perch and grouper, increases
Add fish to accelerate its speed of growth to the food ration of feed, while increase the utilization rate of feed, reduce feedstuff feeding amount, reduce and raise
This is formed, increases fanning economics, and the destruction of the waste and feed remnants of feed to cultivation water can be avoided.
3rd, bottom of pond cultivation pasture and water can not only be purified water, and enough oxygen can also be provided for perch, improves perch
Motion activity, so that the perch of cultivation reduces fat content, the tight meat of squama is real, meat flexible.
