Description
Technical field
Embodiments of the present invention are related to fishery field, more specifically, embodiments of the present invention are related to a kind of pelyad
The breeding method of fry initial feed.
Background technology
Pelyad belongs to salmonidae Coregonus, is a kind of high oxygen consumption cold water fishes, live in high latitude outwash stream and
In lake, three kinds of three types, i.e. river type, lake type and river lake type can be divided into.River type species, they are in migration to river
Egg reproduction in stream, juvenile fish again to lake forage fatten by migration, carries out the migration of different length；Lake type species, they are adapted to
Lake hydrostatic life, can complete all biological process of the vital movements such as forage, growth, breeding；And river lake type species, they
Between river type and lake type species.Comprehensive nutrition in pelyad muscle, protein, unrighted acid, required amino
Acid content is far above most of common cultured fishes, and muscle protein content average out to 18.83% is only lower than snakehead, fat
Unrighted acid is higher than saturated fatty acid content in content average out to 13.75%, aliphatic acid, and height therein is unsaturated
Content of fatty acid is higher, amino acid content average out to 17.48%, A wide selection of colours and designs, Fresh ear field (glutamic acid, aspartic acid, third
Propylhomoserin, glycine) content is higher, therefore delicious meat, liked by people.At present, each state all selects lake type species to make
For lake, the object of reservoir and pond aquaculture.
Pelyad belongs to filter-feeding fish, and mainly ingest planktonic organism, also absorbs part benthon.Squab prelarva master
Ingest wheel animalcule and nauplius, life that the species ingested after alevin stage is skill angle class, have mercy on sufficient class, aquatic insect and some bottoms are dwelt
Thing, to survive to require, although requirement of the prelarva to bait is not very strict, using yield to require, the quality and quantity of bait
Production to artificial culture pelyad still has a great impact.
The artificial culture of pelyad will pass through Juvenile stage, fish for transport, maturity inspection, ovum artificial collection, hatching, fry
Several stages such as cultivation and fishpond cultivation.The artificial culture complete set technology of current pelyad is less, Chinese patent
200910113538.2 disclose a kind of method of pelyad artificial breeding, describe in detail several from Juvenile stage to fry rearing
The operating method in individual stage, in the fry rearing stage, the fry after membrane is transferred in breeding groove and raised, the breeding groove depth of water
30cm, breeding density is 400 tails/L, and water-soluble oxygen amount is more than 7mg/L, and fry starter diet is artemia, and daily feeding volume is fry
20% or so of gross weight, feeds point 6-8 time, and until fry growth to more than 1.5 centimetres of body length, and shadow reacts clever to external world
When quick, emerge to fishpond and bring up.The opening foodstuff of spray, a turn food foodstuff are artemia, nutrient composition in the patented technology
Simply, it is unfavorable for the cultivation of spray.
The content of the invention
