What is more exciting than being completely sustainable and not having to buy new fish fingerlings every year? If you are like me you also feel proud to be able to offer such good condition for the fish that you are able to complete the full cycle and hatch your own! Unfortunately it is often easier to think than to do… We can classify the fish in different categories as below: Ovoviviparous fish The reproduction of ovoviviparous fish involve a sexual penetration and the eggs are developed and kept in the female body until they are ready to hatch. Those are able to give birth to babies that are able to swim and already look like little adults. This category of fish is generally relatively easy to breed. Unfortunately those fish are rare and most of them are too small to be grown and harvested for human consumption. We generally grow them for their ornamental qualities as some of them display very nice colours. Here are a few of them: In aquarium we have the guppy, the molly, xypho, platy… In “colder water” the Gambusia also known as mosquito fish are sometimes kept in little ponds to eat the mosquito larvae. Oviparous The Oviparous fish represent the large majority. They lay eggs on the bottom or on a support (aquatic plants, roots …) and the egg will hatch after the incubation period. We can divide the oviparous category in the 2 following subcategories: -Fish spawning eggs but not taking care of the eggs or even eating their own eggs if they find them -Fish laying the eggs and taking care of them until they hatch and sometimes even taking care of the young larvae until they are able to live by themselves. As you can imagine it is generally more challenging to breed the oviparous fish in aquaponics. They generally need specific conditions to breed and reach the needed gamete maturation (ovule maturation). In aquaculture some hormones are sometimes used to initiate the maturation and the spawn. In aquaponics we don’t use those hormones but it is still possible to obtain spawning behaviour in some species. Even when you obtain eggs you will still face the following problems and especially with the first category of oviparous fish which is the most common: Challenge 1: Predation The fish tank surface is generally limited and with a higher fish density than in nature. The bottom of the tank is generally flat and it expose the eggs to the parent’s appetite. Challenge 2: Water pump In aquaponics we generally have a water pump into the fish tank or an overflow with a water pump. This water pump represent a real danger for the eggs and for the young larvae. The young baby fish is generally few millimetres long and extremely fragile. They can be easily sucked by the pump and die. Challenge 3: food availability The new born fish larvae are generally not adapted to eat fish food pellet. They have an extremely small mouth opening and generally eat plankton such as microalgae or zooplankton (little crustaceans). In a classic aquaponics fish tank they have very little chances to find the required food needed for their survival. There is still hope! Now that you are exposed to the number of challenges that we can face, let’s see what we can still do in aquaponics. Green water technique Some fish are spawning on supports such as aquatic plants or tree roots. For those species of fish (gold fish, carps, redfins…) we can present some artificial supports and when ready they will spawn on it...
