Home-based Fish Farm: A Breakthrough Amid the Pandemic COVID-19

Enhancing Marine Biodiversity Research on Indonesia (EMBRIO) IPB University held the 2nd Embryo Talk Series (ETS) in the form of a webinar with the theme "Home-based Fish Farm: A Breakthrough Amid the Pandemic COVID-19" on Tuesday, (5/19) . On this occasion Dr. Yani Hadiroseyani (IPB University lecturer from the Department of Aquaculture) and Dr. Roza Yusfiandayani (IPB University lecturer from the Department of Fisheries Resources Utilization) were present as resource persons guided by Dr. Ichsan Ahmad Fauzi (IPB University lecturer from the Department of Aquaculture).EMBRIO IPB University is a Center of Excellence which has a focus on diversity of marine biological resources. EMBRIO was called to help the wider community specifically to strengthen the family economy by utilizing the yard. The 2nd ETS activity is intended as a form of EMBRIO's dedication to the community.

The event which was held through the zoom application was attended by 221 participants from academics, researchers, students, entrepreneurs and housewives, from various parts of Indonesia. Food security during the COVID-19 pandemic is a challenge at the moment, therefore home-based fish farms are one solution. Aquaponics technology can be used as an option in implementing this home-based fish farm. Aquaponics is a cultivation technology by combining two production systems, namely fish production or aquaculture and vegetable production without soil. The two systems are interconnected by the recirculation of water.

On the occasion Dr. Yani explained that in the recirculation system there will be accumulation of feed waste and fish metabolic waste. "On the one hand there is an excess of organic material, while on the other hand it needs fertilizer so that there is a merger of the two systems with the utilization of aquaculture waste for vegetable production," he said. Fish food is composed of complete nutrition to support fish life. The content consists of protein, fat, minerals, vitamins and so on. The rest of the feed and the results of fish metabolism can later be toxic to fish. This waste will be converted into non-toxic substances by bacteria, in the aquaponic system will grow diverse bacteria. "What is desirable is good bacteria that can convert metabolic waste. Ammonia which is harmful to fish into nitrites and nitrates in the nitrogen cycle and can be utilized by plants," he added Dr. Yani.

He explained, in principle, this activity was to utilize nutrients that were added to the aquaponic system as optimally and as efficiently as possible and to use water and land sparingly. Aquaponic productivity is influenced by fish species, plants, bacteria and oxygen levels for fish and sunlight for plants.


While Dr. Roza shared his experience as an aquaponic practitioner since 2016 until now. In his aquaponic system, Dr. Roza maintains red tilapia fish combined with various vegetable plants such as kale, spinach, long beans and others. "The container that I use for plants is a 5 liter ice cream container, the planting media are rockwool and granular clay, while the fish container is a fiber tub with a length of 2.3 m and a width of 1.2 m with 3 filter chambers and a submersible pump," he said.

Dr Roza conveyed the need to understand the basic principles of hydroponics. Certain plants have different requirements for nitrogen, so they must consider the dosage requirements of each plant. Next things that need to be considered include water quality, plant seed quality and fish seed quality. To get started, the first thing to do is to prepare the plants. "We prepare rockwool media for seeding plants, then the seeds are planted using toothpicks or hands that have been soaked in water. Spinach does not need to be stabbed into rockwool but kale is necessary. Then rockwool is sprayed with water using spray and then covered and stored in a dark place until it breaks the skin, "he said.

Dr Roza added, after the plants germinated and four true leaves came out, the plants were moved to a net pot and placed in an aquaponic container. After the plants are then prepared 3-5 cm red tilapia (10-20 g / head). "I feed my fish morning and evening after work, I can harvest tilapia after four months with a size of 300-400 g / head, besides that I can also harvest water spinach, spinach, long beans and ocra, do not forget to periodic maintenance. "Pesticide-free aquaponics are cleaner, fresher and taste more crunchy, the fish is also fresh," he said.

Now Dr. Roza besides harvesting fish also harvests a variety of plants every day. In addition to food security at home, aquaponics can also be used as a means of education for children at home. Aquaponics activities are easy and efficient if applied at the household scale or at the business scale. Therefore, the two speakers invited the participants to use the yard and the area around the house by growing vegetables and saving fish with the aquaponic system. (IAAS / NAS)
