The Goldfish Gazette, Issue #109 Mosquito Larvae - Goldfish Superfood January 30, 2023 |
Goldfish Care TipsA Free Monthly Resource For Goldfish Enthusiasts In This Issue Mosquito larvae are usually destroyed at the first opportunity they are discovered because of the diseases they spread. However, in countries where serious diseases are not carried by mosquitoes, the larvae can be used as high-value Goldfish food. Mosquito Larvae - Goldfish Superfood
Mosquito larva hanging at the water surfaceMosquitoes can be a nuisance to humans, but their larvae are a great source of nutrition that I consider a superfood for Goldfish. They are incredibly easy to find, especially in ponds and other water sources.Mosquito larvae provide Goldfish with a high-protein meal that is packed with essential vitamins and minerals. Furthermore, they are a great source of healthy fats and carbohydrates. Not only are they a great source of nutrition for goldfish, but they are also a fun and engaging snack for them. Goldfish become very adept at hunting them, even the visually impaired varieties such as Moors. What are Mosquito Larvae?Mosquito larvae, also called wrigglers, are the aquatic stage of the mosquito’s lifecycle that hatch from eggs laid on the surface of still water. The eggs hatch within 48 hours and the filter-feeding larvae grow rapidly if there is sufficient food available.The larvae spend a lot of time at the water surface with their siphon tube pushed through the surface tension as they are air-breathing. Between four and nine days after being laid, the larvae pupate and a day or two later hatch out as adults. Benefits and Nutritional Value of Mosquito LarvaeMosquito larvae contain a variety of nutrients that can support the health and growth of your Goldfish. They are a great source of essential fatty acids, which are important for normal growth and development. They are also rich in protein and amino acids that are beneficial for boosting immunity in Goldfish.Additionally, mosquito larvae contain essential vitamins and minerals that can help your Goldfish grow strong and healthy. Newly hatched larvae can be fed to Goldfish fry as a first food but they struggle to swallow them. Within hours they grow too big for the fry to eat so I usually wait until the second week before feeding them to fry. There is no better food for fry or juveniles. Growth is accelerated considerably over any other food options. As an example, I recently needed to increase the size of a Black Moor juvenile that was half the size of its siblings. I put the 20mm fish into 28oC (82oF) water, and fed it mosquito larvae continuously. As the larvae are air-breathing, I was able to maintain a supply of non-polluting food in the tank at all times. The fish grew to 35mm in 14 days, and the food cost me almost nothing. Feeding Mosquito Larvae to Your GoldfishMosquito larvae are less than 1mm long when they first hatch but quickly grow to around 7-10mm before they pupate.Newly hatched larvae can be fed to the smallest fry, but adult Goldfish can easily eat the fully grown larvae and pupae. If you are feeding small fry, grow the larvae to the maximum size the fry can easily swallow. Growing the larvae bigger means fewer larvae are needed to feed your fry. To feed adults, I grow the larvae until I see a few pupae appearing, which means the larvae have reached their maximum size. Where to collect mosquito larvaeYou have two options to source live larvae:1. Puddles of stagnant water near your home 2. Collect eggs and raise your own. Generally, the cleaner the water, the fewer larvae you will find present. It is the smell of decaying matter in the water that attracts the females to lay their eggs. I collect egg rafts deposited on the water surface of a specially prepared tub daily, and place each day’s collection into individual raising containers. I then know when the eggs were laid, and how long it will be before they are ready to harvest. ConclusionMosquito larvae are an often-overlooked superfood for Goldfish, but they can provide a range of health benefits that can’t be found in other Goldfish foods. They are rich in essential vitamins, minerals, and essential fatty acids that can boost Goldfish immunity and accelerate growth. They are packed with proteins and amino acids that help your Goldfish stay healthy and active. With their high nutritional value and low cost, mosquito larvae make an ideal food source for Goldfish.For more information, go to my Mosquito Wrigglers page... Comments? Ideas? Feedback?
