My larger loaches and similar fish prefer trout-food pellets to other dry food. I only dare to give it every 2 weeks, as I am not sure about the content. The farm, I got it from, stated it should be free from medication, as medicated food would be not allowed for growing fish for human food. Does anybody have any experience in that field? thanks

I know the fish love it.
Should be treated with caution.
hi there, i work within aquaculture, we are an industry of hard working professionals growing trout and salmon for human consumption and i can assure you that there will be no antibiotics added to the food unless in the unusual circumstances that a bacterial infection were present, in which case a veterinarian would be required to write a prescription, and there would be a period after the treatment had finished (usually a month or more, depending on the medicine) before the fish would be safe for human consumption, and the flesh is tested to ensure that there are no unsafe residues remaining. The whole process is highly regulated and audited
if the farmer assured you that this was not medicated feed then i would be surprised if he were lying to you, why shoud he?
i dont mind if folks like to eat wild fish (hopefully sustainably caught non-vulnerable species) as apposed to farmed fish but please don't spread untruths. To dispell a few more myths, there will also be NO growth promoting hormones, these are illegal. Pigments are used but these are usually yeast derived rather than synthetic. Even the synthetic ones are anologues of the same compounds that give shellfish their colour. Many foods that we as aquarists use also contain these same pigments in order to enhance colouration, so they are completely safe both for fish and for fish that are for human consumption.
As for the suitability of trout food for aquarium fish, i would agree that it will be higher in fat and protein becuase farmers want their fish to grow optimally, but is probably along the lines of beef-heart in terms of its calorific value, so i would give it as a treat but as with most feeds and foods, most things are good if you dont overdo it

When I was a kid I spent a whole summer holidays working for a well known importer and wholesaler of ornamental fish. One day I got to open 25 kilo bags of BP salmon grower and weigh it out into set amounts, before it was repackaged as a very well known brand of catfish pellet. The same company also does something very similar with sea trout pellets of different sizes and sells it to this day as a well known brand of high protein food.
Use it very sparingly!!!
The same company also used to mix flake food into dental plaster and sell it as 'holiday feeding blocks'.

You don't work for a company called Marine Harvest do you? I note you're in Argyll, the old man and I have caught a couple of their escapee salmon in Loch Linnhe and Loch Leven over the years.... /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />
Hi Jarcave, are you local to argyll? i'm looking out over loch linnhe at the moment
hmmm hopefully not too many escapees about these days. /blush.gif" style="vertical-align:middle" emoid=":blush:" border="0" alt="blush.gif" />
fin-shape is not as reliable as you might think for telling whether a fish is farmed or not. i have seen wild fish with more rounded fins and farmed fish with perfect fins. if you think its farmed best look for the vaccination marks internally to confirm, usually a patch of strands/bands of fibrous connective tissue among the internal organs that look a bit like cobwebs sometimes accompanied by pigmentation on surfaces of organs like a charcoal black peppering. Though if in doubt and it might be a wild fish returning to spawn its probably best left to get on with it.
i have heard that the wild catch is good in the river lochy this year with more than expected returns of two-sea-winter fish and in good condition. they are also starting to get a good return of adipose-clipped fish that the restocking hatchery released 2 years ago.
hopefully the trend will continue

Got your PM. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />
I live in Derbyshire but I do spend a lot of time in Argyll every year (I'm a qualified deer stalker and have ground up there). I know Fort William extremely well. I was last there about four weeks ago when you had the bad storms. I was actually in Crannog having lunch as the restaurant got battered by the wave, before having to close for the day.
It's been a while since we caught salmon in Linnhe or Leven. The last one was close to Ballaculish bridge. It did look like a stockie though. Split fins and tail. This year I only managed pollock. /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> I think we were too early for the mackeral. But had a good days trout fishing on Loch Lundavra.
I keep reading good things about the Lochy. It's just a shame it can only be booked by the week. next time I plan on having a day or two on the Leven (If they still do day permits?).
All the best
