I think there IS a difference between a stocked rainbow and a stocked brown. Browns are the indigenous species and so supplementing the naturals with stockies is acceptable IMO and when done sympathetically. Rainbows are a faster growing, more aggressive species introduced to this country to satisfy the boom in people wanting to catch trout. they're also more nomadic than the territorial brown and so are likely to disappear into other stretches nearby. We dont want to see 'spartics' 'blues' and 'goldies' in our chalkstreams do we.? lets stick with indigenous fish (preferably from the broodstock in the river)I still cannot see any difference at all between a stocked rainbow or a stocked brownie. They're all triploid so it's just a difference in colour to me. If there has to be a stocking I think sensible size and quality of fish is the most important thing. Thinking that stock browns are somehow more natural than stock rainbows is a cop out to me. Like you say sewinbasher, different views I guess.
