What should i feed my aquaponics fish? food selection depends on which species you are trying to raise in your aquaponics garden. generally speaking, fish food should consist of the following nutrient breakdown: 32-45% proteins; 4-24% fats; 10-30% carbohydrates; 1-2.5% minerals; 1-2.5% vitamins; however, some fish require more protein than others.. Fish eat an amazing variety of foodstuffs. it is important to recognise that you are not just feeding the fish. fish food is also indirectly the source of food for the aquaponic bacteria that are necessary for a successful biofilter. in addition, it is also the ultimate source of all the plant nutrients required in an aquaponic system.. In an aquaponic system, the fish feed is one of the most important inputs. there is a direct relationship between the feed going into the system and the growth of your plants. think about it: you add feed into the system, the fish eat the feed and produce ammonia, bacteria convert ammonia into nitrates, the plants consume the nitrates and grow..
You should be using an aquaponic fish food that provides 30-40% protein and contains a good source of other essential vitamins, minerals, and nutrients. keep in mind that younger fish and those living in colder waters will require more protein and fat than older or warmer water varieties.. If you have a small amount of fish, you may need to feed your fish more frequently so that they will produce the amount of waste that your plants need. if you have too many fish for your plants, you can reduce the number of times that you feed them. to get the most out of your aquaponics fish, you should be feeding with quality food. since the waste of the fish makes your plants grow, good quality food will provide your plants with the best nutrients that they can get.. The fish to plants ratio is directly dependant on the feeding rate in a properly maintained aquaponic system. in general, fishes use about 80% of food and excrete the rest 20% as waste. the amount of feed fed to the fish daily is considered for per square meter of plant growing area..
