After Tylorrhynchus heterochaeta Quatrefages paedomorphosiss are to 5 guiding principle section nectocaete, need to add in bait and wash, through 300 mesh, the fish that pocket washes filtration by rubbing with the hands
Powder, feeding volume is eaten up in 5 hours by Tylorrhynchus heterochaeta Quatrefages germling and is defined；
6), mark thick phase water quality management:
After Tylorrhynchus heterochaeta Quatrefages paedomorphosiss are to 5 guiding principle section nectocaete, start to change water desalination；The thick region of water suction mark by culturing area
Interior, day salt reduction degree be less than 2 ‰, until mark thick region identical with culturing area salinity when, remove mark thick region colour bar cloth, allow standing grain
Worm seedling is naturally swum and carries out adult cultivation to full pond；
7), cultivate period management:
The early stage depth of water keeps 20～30cm, is beneficial to the growth and breeding of Micro Algae, and after larval growth to 60 firm sections, the depth of water increases
It is added to 30～50cm；Drain within every 15 days water, the dry at the bottom of pond of dew 1～2 day, promote at the bottom of pond bait decomposition and benthic algae breeding life
Long；The girth of a garment according to water and water colour change carry out changing water, change water and can utilize fresh free of contamination river, through 40～60 mesh sieve tulles
Filter, you can bring a large amount of unicellular algas and organic debrises, provide food for Tylorrhynchus heterochaeta Quatrefages, be avoided that trash fish enters beach again；Bait
Material feed adheres on a small quantity more eat, take the circumstances into consideration to increase and decrease according at the bottom of pond residual bait amount, typically daily bait throwing in 3 times；In breeding process, water body dissolved oxygen
More than 4mg/l should be maintained at；
8), cultivation harvests:
Tylorrhynchus heterochaeta Quatrefages have group to float habit, available drainage collection in mating period, lay 100 mesh sieve tulles in discharge outlet and are collected by filtration,
Long 10～the 15m of net, network interface will cover discharge outlet and prevent from escaping.
2. a kind of semi-artificial nursery mudflat aquaculture method of Tylorrhynchus heterochaeta Quatrefages according to claim 1, is characterized in that, described step 2) water
In the step that body is adjusted, also include: after 6～7 days, the property of medicine eliminates, and applies fertilizer 200～300g/m by fermentation2Afterwards, such as
Really after 2～3 days, water transparency is more than 40cm, need to take the circumstances into consideration to apply carbamide 2～4g/m3, compound fertilizer 4～8g/m3, to cultivate basic life
Thing bait.
