Abstract: An aquafarming system is provided that includes a cultivating barrel with a multi-floor net assembly for the cultivation of shellfish creatures or the like. In the aquafarming system, the use of the multi-floor net assembly allows an increased cultivating area such that the quantity of the shellfish creatures being cultivated can be increased to thereby increase the productivity. At the harvest time, the multi-floor net assembly can be lifted up so as to be separated from the cultivating barrel such that the cultivated shellfish creatures can be easily and conveniently collected to reduced labor time and cost.

Abstract: Disclosed herein is an improved closed algae cultivation system that has an algae supplier, a first conduit, at least two containers, and at least two light light-emitting devices. The algae supplier is coupled to the at least two containers via the first conduit. Each container includes at least one sidewall, a bottom and an upper lid, which together define an accommodating volume for accommodating an algal stock culture from the algae supplier. Each container is made of at least one opaque material and includes a first opening disposed on one of the at least one sidewall, and a second opening disposed at the bottom.
