One way to increase the production of aquaculture is by applying aquaculture technology. One example of the application of technology in aquaculture is the use of waterwheels and the application of fish farming with the Recirculation Aquaculture System (RAS).  Fish generally require oxygen for breathing and metabolism. Lack of oxygen can cause fish to become stressed, sick, or even die.  (shutterstock.com) The oxygen content required by fish varies depending on the type of fish and its life stage: 1. Fish in the spawning, egg, and larval stages: Requires up to 6 mg/L of oxygen. 2. Freshwater farmed fish: Requires DO (Dissolved Oxygen) 4-6 mg/L. 3. Shrimp: Requires DO 4-8 mg/L. 4. Tilapia: Requires 7 ppm dissolved oxygen. To increase fisheries production, the amount of harvest must be increased. One way to increase the amount of fish farming production is by applying intensive fish farming techniques with high stocking densities. Intensive fish farming with high stockin...

Disease attack on cultured fish can be prevented if the culture environment where the fish live and develop is in a healthy condition. Proper preparation of the culture pond, which includes drying, liming and salting, can also prevent the occurrence of disease in fish. The environment where fish are kept can be the cause of fish disease. If the environment does not meet the standards recommended in good fish farming, the fish will be susceptible to disease. Generally, fish diseases will arise if the fish and the environment are not in balance. Disease caused by the environment.  The environment as a place for fish maintenance cultivation media affects the problem of disease attacks. Generally, fish diseases caused by environmental factors cause considerable losses, because these deaths occur and last very briefly and generally kill the entire number of fish being kept. Diseases that kill the entire fish population usually occur due to turnover in the environment where fish are kept...

Fish that are kept either in ponds or in aquariums must be healthy, because healthy fish can grow and develop well. The health status of fish kept in the cultivation medium is influenced by several factors, namely Genetics, Nutrition, Environment and Pathogens.  These four factors influence each other and can be used as a strategy for managing fish health and the environment.  (shutterstock.com) 1. Genetics.  Avoid In-breeding Seeds. Seeds produced from In breeding results have several disadvantages, namely stunted fish growth, susceptible to pathogen infection. To avoid the occurrence of genetic decline due to the results of in breeding, the application of Good Fish Hatchery Methods and Good Fish Cultivation Methods needs to be carried out by fish farmers.  2. Nutrition.  Nutrition has an important influence on the health of the fish being raised. Good nutrition can be obtained from what type of fish feed is given. Fish feed that is given the right type, quanti...

The production of black tilapia ( Oreochromis niloticus Bleeker ) seed class is formulated as an effort to improve quality assurance and food safety, considering that black tilapia seeds are widely traded and have a great influence on cultivation activities so that certain technical requirements are needed.  Production of black tilapia seed grade scatter seed.     Production requirements:  Aquaculture pond.  tilapia (shutterstock.com) a. Location of the pond.  - Pond water source.    Clear unpolluted water available throughout the year. - Ponding area.    The pond area is free from flooding and free from the influence of environmental pollution. - Pond soil type.    Sandy clay loam soil with a ratio of 3: 2.  - Altitude of fish farming land.   0 m to 1,000 m above sea level. b. Container.  Fish larvae production. - The spawning container is a pond with a minimum size of 400 m2. - Larval rearing containe...

Catfish is a type of freshwater fish that is widely consumed b Indonesians because it tastes good if this fish is fried or grilled. This catfish is a type of fish that easily recognized by everyone. The Characteristics of catfish are that it has aslippery body, is slightly flattened lengthwise, and has a long “mustache”. This catfish mustache sticks out from around the mouth.  Catfish is high in protein with a very low fat content. This makes catfish a very healthy fish to consume. In addition, catfish contain omega-3 and omega-6 fatty aids needed by the body.  Catfish (shutterstock.com) The demand for catfish meat is increasing day by day. With the increasing market demand, the amount of catfish produced by fish farmers needs to be increased so that the market demand for catfish can be met. Below is a look at what it takes to increaasing catfish production : 1. Quality of stocked catfish fry.  Catfish seed that will be stocked must be of high quality and superior for cul...

Fish is one of the food ingredients needed by the community to fulfill the need for animal protein. Fish meat generally contains protein, vitamin D, Vitamin B12, iron, selenium, zinc, and iodine which are beneficial for our bodies.  Cyprinus carpio fish is a freshwater fish that has important economic value and is widespread in Indonesia. Cyprinus carpio fish is classified as a popular consumption fish in Indonesia and is consumed by the community to meet nutritional needs of animal origin.  Cyprinus carpio fish (shutterstock.com) The number of Cyprinus carpio fish produced by fish farmers needs to be increased so that the market demand for Cyprinus carpio fish can be met.  Below can be seen the things needed in an effort to increase the production of Cyprinus carpio fish:  1. Quality of Cyprinus carpio fish fry stocked. Choose high quality and superior Cyprinus carpio fish seeds for cultivation. Superior fish seeds will produce healthier and more productive fish. S...
