`top lake had fish in it already a long time back, top lake is one of the lakes where i can say i have never seen so much natural food in a dam, like this past weekend, there are so much snails in there at the moment that when you reel out on each and every rod there is a few snails and if you bring back grass you will have a handful. These fish are the correct strain if you look at their heads and tails.
Rushmere was stoked with carp from top lake, ike the lady was a top lake fish given to rushmere,but the fish were taken back because the water wasnt managed. Top lake has no need to feed x tons a year because each member there buys feed for the fish like most give a 50kg bag of trout pellets every 2nd month plus the amount of natural food going in and only boillies being used there is no need for extra feed, there is more than enough in there, and remembr i also said they control the population so they keep the biomass intact so that if anything goes bad that the natruals can atleast keep the fish at their current weights.
And please get this, the post about feeding fish from the fry stage is to do with WORLD RECORD carp not big carp but massive carp, not all carp grow to those sizes very few do, because it depends on a hell of alot. Some fish will gain 20-25lbs a year and grow like that for 5 years then all their growth just stops, or they grow very fast and die, its not just ok that fish has a big head lets grow a record. Its easy to get 30-50lb carp because on a world standard thats pretty average, 70's 80's and 90's are what they're aiming for at the moment. If it was easy and a simple task to grow 100lb plus fish there would be more than one scar trust me.
If you think its a simple task to grow big carp and im talking a load of crap, go phone a koi breeder that has at least won some sort of competition and ask him how to grow carp as fast as possible, just grab a chair you might be there for a long time. To give you an idea how hardcore these guys take it, they add salts,minerals,and feed the fish various diets and try to establish an environment for the specific fish to grow the fastest in once they have this figured out the growing starts.
