Fish diet/nutrient requirementsĬrayfish are omnivorous so that means you can feed them a varied diet. Ideally, dissolved oxygen requirements should also be maintained above two parts per million (ppm). However, if they have no way to climb out of the water, they will drown. If you don’t have a filter or airstone, they will climb up to get the oxygen from the air. The ideal pH level is between 7.2 and 8.2 Oxygen requirements SunlightĬrayfish don’t really require light in their environment, so either provide shade for your tank or provide many hiding spots inside the tank. Maintain your tank’s temperature between 70 to 75 deg F to keep your crustaceans happy. Another thing to keep in mind when preparing a tank for Crayfish is that it should have plenty of hiding places. Keep in mind that your tank should be taller than longer as most crayfish species like to climb out of the tank. Given the stocking density, if you want to keep five crayfish, for example, then you will need a 25-gallon tank. You need to consider how many Crayfish you want in your system. For larger species, the stocking density is at 15-20 gallons of water per Crayfish. Requirements for Caring for Crayfish in Aquaponics SystemsĬheck out the requirements to have a thriving crayfish aquaponics setup: Stocking densityĬrayfish need space to move around, so ideally, the stocking density would be 5 gallons of water for every Crayfish. It’s less aggressive than other species, which makes them ideal for keeping. Dwarf orange – native to northern Mexico and southern/southeastern U.S, this species is the most popular among hobbyists because of their small size and their interesting bright orange color.They can grow up to three inches only, but they’re considered among the more tolerant of the different crayfish species. ![]() Miami Cave Crayfish – native to Miami, Florida, this species is colored bright to light yellow-orange.They can reach a length of 8.5 inches, so they will need to be housed in a larger tank. Red claw – this species is native to Northern Australia and they can have an interesting color spectrum ranging from blue-green to almost black with yellow lines or spots.If you are considering adding Crayfish to your setup, consider the following species: While Crayfish can be fun to keep in your aquaponics system, many species cannot thrive in captivity. Because they’re readily available, keeping Crayfish can be an inexpensive way of adding that unique touch to your system. They may not be as popular as most fish species in aquaponics systems, but they have been successfully raised in thriving aquaponics setups. Why Raise Crayfish in Aquaponics Systems?Ĭrayfish (also called crawdads or crawfish) are freshwater crustaceans found not only across water bodies in the U.S, particularly in Mississippi through Louisiana, but also in different parts of the world. In this article, you will learn valuable tips on how to raise Crayfish in an aquaponics setup. These crustaceans may not be your typical aquaponics resident, but they can definitely help in the sustainable method of growing crops. If you’re feeling adventurous and you want to keep unique creatures that can benefit your setup, you may want to consider caring for Crayfish in aquaponics systems as an alternative to traditional fish.
