For fish farmers, especially consumption fish farmers, increasing fish production is a desirable goal. One of the things that can help increase aquaculture production is that it must be supported by good facilities and infrastructure that support the development of aquaculture.  Aquaculture facilities and infrastructure include various facilities and equipment needed to support fish farming. Some examples of these facilities include: 1. Aquaculture Ponds.  Ponds used for fish rearing must be well designed to meet the needs and suit the habitat of the fish being reared. Fish farming ponds must be able to hold sufficient water volume and have water available throughout the year. The fish farming pond should also have ideal environmental conditions for fish growth.

Make sure the selected...

Green economic development is a development model that combines economic growth and environmental quality improvement. The green economy is a resilient economic growth that does not exclude environmental problems. This green economy prioritizes low-carbon development and pays attention to its social impacts.  The green economy concept is an economic concept that takes into account economic growth and prevention of environmental damage. The green economy also includes three policy areas, namely the scope of economic development, social development, and environmental protection. The goal of the green economy is to achieve balanced economic growth by maintaining ecosystem balance and reducing negative impacts on the natural environment. (shutterstock.com) In aquaculture the concept of green economy needs to be applied because in principle the output of aquaculture activities in addition to fish production there is also waste released. Waste production from fish farming will be more if...

Freshwater fish are fish that live and grow in freshwater environments, such as in rivers, lakes, and fish farming ponds. These fish do not experience changes in salinity because freshwater fish are not in the sea. Some examples of freshwater fish include Cyprinus carpio, catfish, tilapia, gourami, and Barbonymus gonionotus. These types of fish have a variety of shapes, sizes, and food habits depending on the species. In the article below, the author will explain some of the differences between Barbonymus gonionotus and Cyprinus carpio. Cyprinus carpio and Barbonymus gonionotus are two types of freshwater fish that have different characteristics. These differences can be explained in the description below:  1. Barbonymus gonionotus fish: a. Distribution.  Naturally, Barbonymus gonionotus fish spread widely in Indochina and the Sunda islands. In Indonesia, this fish has been cultivated in ponds since the 19th century and spread to other islands in Indonesia and Asia including S...

One type of fish that can be cultivated with a biofloc system is catfish. This catfish is a type of carnivorous fish that requires feed with high protein content for its growth. The protein content of the feed is not all absorbed in the body of the catfish, only about 20-30% can be absorbed, the rest accumulates in water both in the form of feces and urine.  Organisms that live in water in the metabolic process generally produce ammonia as a result of its excretion. High protein from uneaten feed residues and metabolite decomposition results will produce the same by-product, ammonia in the form of Total Ammonia Nitrogen.  biofloc fish pond (shutterstock.com) Waste from aquaculture in the form of ammonia can reduce the level of water quality and this waste is toxic and can kill the fish being raised. Ammonia produced from fish farming will be a limiting factor in the success of fish farming. Fish farming activities will be successful if ammonia control can be done with good man...

Fish farming with the biofloc system is currently in great demand by fish farmers in Indonesia because fish farming with the biofloc system has several advantages when compared to traditional fish farming. These advantages can be explained in the article below, which include:  1. Controls toxic compounds. Fish farming with this bioflock system can provide the advantage of controlling toxic compounds. Bacteria that are heterotrophic and live in aerobic conditions can control and eliminate toxic ammonia levels in the cultivation media into cell proteins.  biofloc fish pond (shutterstock.com) Other compounds are oxidized by nitrifying bacteria into nitrite by Nitrosomonas bacteria. Then this nitrite is converted into nitrate by Nitrobacter bacteria. With this decomposition process, the water quality in the biofloc system cultivation media will be more stable and optimal. This good water quality will provide benefits because it can reduce the stress level of the fish being ra...

Freshwater fish farming activities with intensive cultivation systems will cause the emergence of residual organic matter in fish rearing media. The presence of high organic matter will cause the need for water for replacement to be large. In line with that, to reduce the need for water and to streamline the need for feed, the application of biofloc system fish farming is very appropriate to do.  Biofloc Pond (shutterstock.com) Biofloc technology continues to develop over the years. Among other things, there is the utilization of new bacteria and the use of the latest technology, as well as expanding its application to the cultivation of various types of fish. Unlike traditional fish farming, biofloc technology utilizes the waste medium to produce compounds that are useful for the development of the fish. Biofloc fish farming is one of the new technologies in aquaculture. Fish farming with this system comes from the adaptation and modification of domestic activated sludge sewage tr...

Gold saum fish is a type of freshwater fish that comes from the Cichlid family. This fish comes from the Pacific side of South America. Gold saum fish live in public waters in rivers that have moderate lighting levels.  When viewed from the body shape, fins and colors, Gold saum fish are suitable to be kept and used as ornamental fish because these fish have beautiful shapes and colors. Ornamental fish hobbyists will also feel interested and happy if they see this fish kept in an aquarium.  When we are going to keep Gold saum fish in an aquarium there are several things we need to pay attention to including maintenance containers, water quality, feed and care. Gold saum fish (shutterstock.com) Maintenance container. The maintenance container that can be used to keep Gold saum fish must be selected from safe materials, usually for the selected maintenance container is an aquarium made of glass. The shape of the aquarium used to keep Gold saum fish can be rectangular or rectangu...
