Hi James.
Horseshoe may be a commercially run fishery but it is hardly overstocked in comparison with the 'baggin up' match puddles being discussed here. In fishery management it is suggested that the ideal weight per acre is under 300lbs which will allow for decent growth rates. I don't know what the biomass of fish per acre is at Horseshoe, but as the fish (tench in particular) grow very big, I'd imagine it is well under 300lbs an acre. Apparently some of these baggin up puddles boast a stocking density of over 1000lbs per acre, which effectively prevents any semblance of a natural aquatic bio-diversity existing.
1000lbs per acre, thats a tad conservative an estimate for the puddle this article was based on; 7000lbs landed on second days match divided by larger of the two areas given (3 acres) = 2333lbs per acre = grossly over stocked.
What is needed is scientific research to be conducted as too what is a safe, welfare friendly stocking density.
As an example Boddington reservoir, BW say they stocked 50,000 carp now weighing an average of 6lb each, the lake is 68 acres, though at the top end of the stocking level scale, its possible for fish to find safe sanctuary and weed still grows but only where anglers tend not to fish most of the time.
Head to the dam pegs and you'll find huge numbers of scarred up battered and beaten fish.
Then head up towards the less popular swims you'll find good conditioned fish that are undamaged.
My point being despite a biomass of aproximately 4400lbs per acre, this lake functions without the necessity of aerators etc.
Thing is like I said before, facts are needed and these facts need interpreting then implementing into legislation because guide lines will inevitably be ignored by any greedy so and so that opts to do so.
If agriculture has to work with stocking density legislation for livestock then it seems perfectly reasonable that fishery's follow suit because else greedy owners will continue to over inflate stocking numbers unchecked.
Chris, you asked; "Dave, if you're still there, can you click on the website at the bottom of my post and see if it opens it, as on my computer it don't?"
If you were referring to the link to your site, then yes it works fine, some nice carp pics, any of chub?
