Embodiment Construction

[0024] A preparation method of bait for larvae of Chlamys farreri, the specific steps are as follows:

[0025] Step 1 Preparation of Microalgae Culture Solution

[0026] The composition of the culture solution (weight ratio): 0.4 parts of butylidene diurea, 0.3 parts of ammonium oxalamide, 0.01 parts of ammonium polyphosphate, 0.002 parts of potassium metaphosphate, 0.004 parts of diammonium phosphate, 0.005 parts of ammoniated calcium superphosphate, NH 4 NO 3 0.8 parts, KH 2 PO 4 0.004 parts, Na 2 SiO 3 9H 2 O 0.02 parts, NaHCO 3 0.8 parts, NH 4 VO 3 0.02 parts, ZnSO 4 ·7H 2 O 0.08 parts, Cr 2 (SO 4 ) 4 24 hours 2 0.02 part of O, 1.2 part of f / 2 trace element solution, 0.8 part of vitamin S-3 solution, 0.4 part of soil extract, 0.6 part of sea mud extract, 0.0001 part of indole acetic acid, 0.002 part of spermidine, 0.5 part of Chinese herbal medicine extract 1,000 parts of seawater after boiling and cooling magnetized; use 15% acetic acid solution (volume ra...

Abstract

The invention discloses a preparing and feeding method for chlamys farreri larva baits, and belongs to the field of aquaculture. In a chlamys farreri seedling growing process, the problems of tender physique of seedlings and low survival rate which are caused by inadequate baits exist. The technical key points of the preparing and feeding method are that four ocean microalgaes are aquacultured by magnetized water and blue light so as to prepare algae paste which is fed to chlamys farreri larva seedlings; the nutrition is comprehensive, the chlamys farreri larva grows fast and is strong in physique and high in survival rate; the microalgaes are cultured by the magnetized water, so that microalgae bodies grow fast and are pure in color; the microalgaes are cultured by a water storage tank, so that the cleaning is convenient, the cost is low, damage caused by collision seldom occurs, repeated use is realized, and pollution is basically avoided; with the adoption of blue light cultivation, the EPA and DHA contents in the microalgaes are high; the algae liquid is prepared into the algae paste for feeding, so that the feeding amount is easy to control, and a water body cannot be polluted; the baits can be produced all the year round, the occupied space is small, and the transportation and the storage are facilitated.

Description

[0001] Technical Field The present invention belongs to the field of aquaculture, and in particular relates to a method for making and feeding bait for larvae of Chlamys farreri. Background technique [0002] Chlamys farreri, scientific name Chlamys Farreri, common name scallop clam, sea fan, belongs to Molluscs, Phyllobranches, Pearl Oysters, Scallopidae, and Scallops. Generally, the shell length is 74mm, the shell height is 77mm, and the shell width is 27.5mm. The two shells are slightly symmetrical, and the right shell is relatively flat. Pale off-white color. Chlamys farreri live below the low tide line, with fast currents, high salinity, high transparency, 10-30m water depth on rocky reefs or hard seabed with shells and gravel. The double shell can be opened and closed to drain water, and it can swim for short distances with reaction force. The shell closing movement makes a crisp sound, and can shed the silk to swim in the water. During normal life, it opens its two s...
