Carp fish is among the typical fish in the Asia-Pacific region with both foreign and domestic species. Domestic species include kalibaus, mrigal, and Katla, while foreign species include grass carp, black carp, bighead carp, common and silver carp. Maintaining carp fish farming requires skills and knowledge so that the business can be profitable. The technique employed in carp fish farming is determined hugely by financial capabilities, environment, and availability of modern equipment.

It is suitable for large-scale fish farming, and one of the best ways of farming carp fish is using cages. Pontoon cages are easy to install when you use the right supplier. You will also need to buy or hire floating pontoons, bridges, and docks to make the farm accessible.

A fish hatchery is an artificial center where juvenile fish are reared for the natural water or sold into fish farms. Many farmers are attempting this idea since it has become very profitable as many fish farms demand different fish species. It brings more return on investments for medium and large-scale businesses compared to small-scale ones. It is a brilliant business opportunity; however, you have to work for it to be successful.

Shrimp farming can either be freshwater or marine. Marine shrimp farming is common in areas like Western Europe, Asia, and the US. Freshwater farming is best done in warmer climates and involves rearing shrimps from being juvenile to adulthood and selling them for income. For more profits, it is best to practice large-scale farming. Besides that, if you want successful freshwater shrimp farming, you have to invest in the pond. Ensure your pond is high quality with enough supplies for the fish to grow optimally.

Shellfish farming is aquaculture farming that involves fish species like mussels, oysters, scallops, and clams. As a farmer, you have to be responsible for protecting the fish from predators to increase production. The process begins from rearing larvae into juvenile fish, and this is done by technologically advanced methods designed to ensure their maturity is reached in perfect condition. 

Pontoon cages are also another way of rearing shellfish as this ensures they are in their natural environment. When constructing the cages, include a floating bridge that is of high quality to access the farm whenever needed.
