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...
