As the demand of high quality protein increases with the increasing income level of Malaysian, many aquaculture systems have been established to suit the demand (Department of Statistic Malaysia, 2017; Teh, 2012). However, most of the aquaculture systems have the potential in causing disruption of the environment and required intensive land use as they are practiced in brackish water, coastal areas, earthen ponds, lakes, ex-mining pools and so on (FAO, 2008).
As a comparison to the conventional aquaculture practices in Malaysia, this project aimed to introduce a new way of aquaculture system which can be set up in urban area of Malaysia. The target site of this project is located at the Kuala Lumpur City Centre (KLCC) and the culture system uses transparent tanks to resemble the walls of a building where the inner unoccupied area of the building can be served as office, restaurant or even home.
The main feature of this new aquaculture system is that it uses multiple large rectangular tanks to act as the walls of a
For example, furunculosis caused by Aeromonas salmonicida and Aeromonas liquefaciens which causes reddening of fins, vibriosis by Vibrio anguillarum with bleeding around mouth and gills, bacterial kidney disease (BKD) by Corynebacterium which causes bleeding of kidney and liver, bacterial gill disease by Myxobacterium with swelling and reddening of gills, and others too (FAO, 2005).
As for walleyes, they are also certain common diseases such as bacterial diseases by Flexibacter columnaris that causes ulcerations on the skin, gills and mouth, Aeromonas and Pseudomonas that causes swollen abdomen, protruding eyes, raised scales and irregular red or grey lesions on the skin. Parasites like trematodes and protozoan can also threatening the health of walleyes as they creating stress to the fish and causing open wounds on the fish body that increases the chances of further infection (Miller,
