“…Feeds account for more than 50% of the production costs in semi intensive fish farming [28]. The commonly used feed ingredients (fishmeal, soybean, and cereal bran) are increasingly becoming scarcer due to a decrease in production and an increase in competition from other consumers [29].…”

Organic wastes can be recycled in an ecologically sound way in fishponds by applying integrated agriculture and aquaculture systems (IAA). This kind of waste recycling can help to protect the environment from pollution and improve fishpond yields. Additionally, IAA provides an opportunity for diversification of the output from two or more existing subsystems leading to higher overall farm economic returns. This study explored the potential application of amaranth wastes (AW) as a dietary ingredient for tilapia in a tilapia-amaranths integrated system (ITA). An experimental diet (AD) contained 10% (based on the control diet, CD) inclusion of AW collected from a nearby vegetable market. The experiments included triplicate treatments with; (i) fish fed on AD, where the pond water was used for irrigating the amaranth plants (IAA-fish), and (ii) fish fed on CD, where no pond water was used for irrigating the amaranth plants (non-IAA fish). 90 days after fish stocking, eighteen 4 m2 amaranth plots were prepared and treated with (i) tap water without fertilization (control amaranths), (ii) water from IAA-fish pond and organically fertilized (IAA amaranths), and (iii) tap water and inorganically fertilized (non-IAA amaranths). The use of AW improved the fish feed conversion ratio. The overall net income from ITA was 3.2, 2.3, 2.6, and 1.8 higher than from non-IAA amaranths, IAA-amaranths, non-IAA fish, and IAA fish sub-systems respectively.

“…Thirdly, WECs can replace fossil fuels to meet the daily energy needs of offshore platform automation, due to low costs and high environmental friendliness. For example, WECs can satisfy the daily power consumption (4.78 kW h) of a typical single column-dual row offshore cage [8]. Fourthly, an efficient layout of WECs along the periphery of offshore structures can reduce the transmitted wave height and provide a mild wave environment downstream, which reduces the motion response of floating bodies.…”
