Looking at Pricey's fine trout and looking at the odd property with either a small stream or lake in it has got me thinking about trout. What sort of conditions do they need? I don't know much about them but I vaguely think brown trout like decent flowing water but rainbows will be happy in a decent sized lake. Anyone know much about them and can shed a bit of light?

Brown trout are native while rainbow aren't. Rainbows only breed in a few locations in the whole of the UK so just about all the Rainbows we catch are stock fish. Lake or pool wise the water for trout has to be well aeriated other wise you get die off in the hot summer weather.

well oxygenated ,a healthy food chain . not too fussy brownies but a natural stream or river rather than a channelled one helps . deep pools and tight flows with some quiet areas for spawning seem popular with them.

The problems with the rainbow trout that we can all catch at our nearest put and take fishery are the price and the quality.

I'm sure plenty of board readers will have shied away from the hideous looking clingwrapped rainbow trout on display at the supermarket. Unfortunately the ones you'll catch at a fishery are fed the same crap at the same fish farm - it's just that they get to swim around a lake for a few days before you pay treble the price for catching and cleaning them yourself.

Another problem (ecologically speaking) is the food itself. Farmed fish are fed on high protein pellets made from wild fish caught at sea in industrial quantities. For every five tons of wild fish removed from the sea, the manufacturers manage to produce one ton of fish food, i.e. an 80% loss to the biomass. Then they add asbestos to the food to stop it catching fire when stored in large quantities, and dye to make the fish flesh a more 'natural' colour. Mmmmmm, nice!

Rainbows are overfed in fish farms, and are genetically altered to become 'triploid' i.e females unable to produce eggs so they grow at an accelarated rate, and this usually means that at least for the first year of their (drastically shortened) lives, rainbow trout have a cardio-circulatory system that is unable to supply their grossly overweight bodies with enough oxygenated blood. That's why you don't get much of a pull from them when you catch 'em on anything other than the lightest of flyfishing gear. They are the lardy couch potatoes of the fish world, as opposed to wild brown trout, sea-trout and salmon who are olympic athletes by comparison, and in the twelve years since I was first informed of what they eat (ergo what they have in their flesh) I haven't eaten a single rainbow trout!

hard to beat the flavour of a brownie from a peat or chalk stream and stock pond fishing is like shooting caged lions.
i find most shop fish are rather too long dead ,even at the seaside most will have been airside for at least 12 hours .
feeding pond fish is always wasteful unless they are veggie fish and they can mostly be fed with "leftovers " like monastic carp .
feeding flesh to make flesh is daft (sand eel soup is quite nice ) and pond rainbows are pasty things ,wild ones are very different being both textured well ,good flavoured and if thats your bag an interesting catch as they can be a bit vigourous when hooked .
even from the same water i prefer brownies .
roll on april

cos i was poorly they got a set aside this year so there should be some fat ones in there next season .

I would agree with everything posted by Gus however, unfortunately farmed fish may be the only way forward in terms of eating fish in future given the depleted stocks.

Although organically farmed and fed on sustainable food sources of course..

Having said that most of the trout around here that's in rivers and canals are stock fish that have escaped (or their parents did!) and taste very nice- even the ones from the canal. I don't think it takes too long in running water with wild food sources to give fish their natural sleekness and flavour. I still think rainbow trout are pound for pound the hardest fighting fish I've ever caught...but then I've only ever caught one brownie and he was a tiddler.

If I was to stock a lake or a mill pond then I'd not be buying in fish food! If possible I might supplement their food with things I could grow myself but the main idea would be to produce a habitat where the fish would live naturally. I would have to ensure there's nothing rare that would be wiped out by the fish of course. I would also not expect to farm and sell trout but to have somewhere where friends and family could do a spot of fishing and have something different for the pot.

trout are carnivores ,cannibals if they can find littler ones or if they are a bit peckish they can be quite ambitious . carp may be better for a "natural pond with suppliments and not using high protien pellets

Silas I have a mate who refuses to eat Sea bass. It stems from the day that his brother caught a 10lb er down in South Wales and he reckons that it puked up a small kitten

Silas, don't let it put you off trout - wild brownies are one of the most delicious and nutritious things you'll ever add to your diet. And they are most certainly a substainable resource!

The only time I've balked at eating a sea bass was an occasion some years ago, when after catching two beauties in an estuary and seeing plenty more splashing around the same pile of flotsam, I got close enough to realise that it wasn't flotsam, but a decaying Alsation carcass. They were gorging themselves on bits of rotting dog!! I gave those two away and settled for a bag of chips on the way home!

Which is disgusting but surely not that different to what fish usually eat- I always assumed the reason why maggots are such a good bait is that they occur naturally in their diet from corpes of dead animals, rabbits, foxes, livestock, birds etc that find their way into the river. Now i'm putting myself off
