A sea cucumber commensalism method is disclosed, which comprises the following steps of: constructing a culture water body exposing a culture pond under the sun and then adding seawater and placing a sea cucumber culture device adding benthic diatom, photosynthetic bacteria and EM (Effective Microorganisms) to culture biological baits at a water temperature ranged between 19 DEG C and 24 DEG C, salinity of 27-33% and a dissolved oxygen content of not less than 5mg/L for one week adding one-year-old young sea cucumber seedlings into the culture water body and adding larval shrimp or fish into the culture water body after two weeks or one month since the sea cucumber seedlings are added. According to the disclosed sea cucumber commensalism method, bred algae or pests can be eliminated by virtue of dietary habits of fish and shrimp organisms, excrements of fish and shrimps can also become important baits for the growth of the sea cucumbers, and the generated residual baits and excrements can be eliminated by virtue of omnivory characteristics of the sea cucumbers, capable of effectively utilizing the culture water body.本發明為一種海參共養方法,包括下列步驟:建構一養殖水體,係將養殖池於陽光下進行曝曬後,加入海水及放置海參養殖裝置,並加入底棲硅藻、光合菌及EM菌(Effective Microorganisms)以培養生物餌料,水溫保持在19~24℃之間,鹽度為27~33‰,溶氧量不小於5mg/L,時間為一週;投放參苗,將1年齡幼參投入該養殖水體;以及投放蝦苗或魚苗,分別於投放參苗2週或1個月後,將蝦苗或魚苗投入該養殖水體。本發明利用該魚蝦類生物的食性以清除滋長的藻類或害蟲,同時魚蝦之排泄物亦可成為海參成長的重要餌料,並利用海參之雜食性特色清除產生之殘餌及排泄物,使養殖水體做最有效之利用。
