    Insect based Koi feed

    Hi guys

    I have been part of this forum since I was 15/16 (now 21) and I am developing a business for my final year university project. Recently I posted some questions on feeding Koi Black soldier fly larvae, these answers were really helpful. The business is based around feeding insects to koi as a more sustainable and environmentally friendly feed. I have some further questions for everybody if they wouldnt mind answering? All help will be greatfully recived.

    Would you consider switching your current food to an insect based diet?
    what price do you currently pay per Kilo for Koi food?

    The diet will be sustainably sourced preventing damage to global fisheries as it is 100% free of marine ingredients. The diet will have a high protein percenatge (approximatly 45%) and represent a more natural based diet, still containing colour enhancement additives.

    Any answers would be great, if you would rather not share this information, pm's are more than welcome.

    Cheers Chris

    I would try it at least one season
    I pay 80 € - 15 kg ...It's about 5,3 € for one kilogram

    1) Would only consider completely changing if the cost vs benefits had been proven. Would be more than happy to do a 50% mix with existing food, but unlikely I would switch completely as Koi are my pets and I like to feed a variety of foods. If I had a fish farm on the other hand, my considerations would be cost vs growth. If the numbers stacked up in that scenario I would completely switch.

    2) £4.40 kilo frozen mussels, £25 kilo Saki Hikari, £11 kilo NT Labs probiotic growth. These are the 3 main foods I've fed this year.


    As for insect based foods..... some anecdotal evidence.

    A relative was given a water feature as a gift, 3 wooden half-barrels stacked on top of each other. No filter, just a pump that was used during the day in summer. In total I'd say it took around 50 litres. They bought 3 tiny shubunkins and chucked them in the bottom barrell which contained around 20 litres. Once autumn came the feature was forgotten about... forever.

    4 Years later I received a phone-call. The feature had rotted and she was emptying the water out ready to dispose of it and a fish came out. I went round there to discover a beautiful 6" long shubunkin. That shubunkin hadn't been fed for over 3.5 years and can only have survived on insects and larvae throughout the time. The colours were incredible, it looked so healthy.

    I took it home and stuck it in an ornamental tank, feeding it predominently on Hikari Gold and Hikari staple. Within a few Months its colours had faded and no matter what I did I never managed to get it looking like the day I picked it up and the only reason I can think of for that was the food I was feeding. I just could not replicate the diet of insects and larvae it had lived on throughout its life.

    That all happened in 2011 and sadly she passed away in May 2018 at around 12 years old. (No parasites or diseases, just deteriorated over 2 or 3 days and died).

    Here's an old photo from 2014. Her colours had already faded by this point but she still put on a further 2 or 3 inches before passing away. The incredibly long fins are a possible sign of stunted growth even though she did continue to grow slowly and spawned at least once per year.

    Insect based Koi feed

    Carp are omnivores so they naturally do not select an insect only based diet, Especially a non marine one. They graze on algaeís and plant life too dont forget.
    Some people purposely run green water at certain times as they believe and i also do to an extent that it really helps with colours? I dont think theres any hard proof but some do seem to show that it works.

    As for the feeding chris, i already feed dried insects such as black soldier fly, silk worm and meal worms etc... as treats or additions.
    I dont believe a purely insect based is any good for carp as there natural food source is very much fresh/live marine based ay such as shrimp and other crustaceans/larvaeís.
    I would definitely feed an insect based food but not soley.
    I cant really give an accurate cost per kilo of what i feed because i feed all sorts ha ha, pellets from saki hikariís range to queni koiís/coppens, fresh mussels and cockles to dried shrimp/flys/mealworms etc... even fresh worms from the compost bins at home.
    I like your idea but as a business venture i think the purely insect base is floored from the off if im honest. Plus its all already out there, any sustainable source can already be bought dried and packaged for koi. It would be a tough market to be in for sure.

    Hi Lee,

    You are correct about green water. On Asian fancy goldfish forums there are whole categories devoted to getting the best green water. They also use green water as a natural filtration with no mechanical filter fitted at all. Those people are really competitive in the show scene so not being able to see their fish all year round isnt a problem.

    Green water definitely improves colouration on goldfish, and probably koi too.

    Hi Lee

    Thank you for your detailed reply, it was really helpful and gave some interesting pointers.

    The diet isnít solely insect based. Itís just using insects to replace the Marine portion of the diet. With a more natural diet for carp. The diet is very similar to other Koi diets but the main ingredients are insects rather than marine fish/oil. The diet is therefore sustainable sourced and more eco friendly. The diet also contains natural colour enhancers, prebiotics and clay. I donít Believe there is another Koi food currently on the market providing this but I may be wrong. The business is aimed at initially supplying a sustainable more natural feed for Koi, goldfish and predatory fish such as cichlids.

    Thanks for the criticism, this is helpful as it allows us to research the floors or potential areas the business needs to be changed on. Thanks for taking time to help. Will have a look into algaeís and possibly working this into the diet.

    Many thanks
    Chris
