The invention relates to an ecological trepang culture method in silt sandy ponds in coastlands, which belongs to the aquaculture field. The method comprises the steps of setting a pond, setting trepang reefs, disinfect the pond, controlling feed water, cultivating feedstuff, stocking young trepang and managing culture. The feedstuff culture which is performed in April to May comprises the following steps: firstly, transplanting benthic diatom in a height of 0.8 to 1 m feed water depth in the pond in the prior period, with 5 to 10 L of benthic diatom liquid per Chinese acre; secondly, transplanting ruppia maritime and amphilhoe japonice, especially, integrally transplanting ruppia maritime through pulling up by the roots according to the quantity of 5 to 15m per square meter, and transplanting amphilhoe japonica according to the quantity of 1.5 to 3 kg per Chinese acre after the transplanting of ruppia maritime; thirdly, poly-culturing mussel organism; fourthly, feeding water to the pond to the depth of 3 to 4 m, and stocking prawns according to the quantity of 500 to 1500 per Chinese acre. In the method of the invention, ecological feedstuff is adopted for transplanting and polyculture, therefore, not only the cost of artificial feedstuff is saved, but also the natural ecological environment is created for trepang culture.
