Sepp Holzer on fish feed

In one of the videos you see Sepp throwing something into the water and the fishing rising to the surface to eat it.  But ... Sepp takes great pride in not feeding the fish - instead he creates fish food habitat. 

He pointed out that the people making the video brought the fish food and asked him to feed it to the fish so there can be something more interesting to put on video.

Further, he pointed out that most of that pelleted fish food that is used for most aquaculture is made from the dead animals that were often extremely medicated in their last days in an attempt to keep them from dying.  It even includes euthanized pets (cats/dogs/horses/etc.)

boy am I glad I read this! I was thinking of purchasing some fish food just for fun but I would actually like to eat some fish out of our pond and don't want to be throwing nasty stuff in the water. I thought there were some tough regulations regarding using euthanized animals for feedstuffs but maybe the regs are looser for fish food.

I'm sure it is heavily regulated.  And, it seems, a lot of regulations are designed to help out one industry or another. 

I think that the recycling of the meat is wise.  I think that concerns over the heavy medication is a valid concern.

When you take that pelletized fish food and throw it on the water ....

Its an ancient technique for farming carps.
Here we add manure on the edge of lakes and that manure feeds algae and aquatic plants wich are the plancton food.
In China they build chicken farms on lakes ,where the chickens poo fells into the water and feeds the algae then the plancton and ultimately the fish.
Such techniques have made westerners to believe that fish really feed on poo or manure.
They were making claims like ,,dont buy fish farmed in China because its fed with human feces,,.
In reality ,these fish that grow in such a sistem where they feed on the zooplancton and phytoplancton blooms are actually wild fish that come from organic farming and much healthyer to eat and of better quality than fish that are fed pellets ( usually,sometimes fish wich   are fed pellets are organic farmed too).
This techniques of naturally growing fish do need a lot of space,big ponds and the density of the fish its like that found in nature not 200 kilos of fish in a cubic meter of water.
