We have plenty in stock Red beard. Got to keep the trout in feed, they are voracious feeders.

cheers stevesmartt we were goining down to see faye tomorrow anyway
but we would like to check your system out if possable some time
we are fairly new at this (having lots of fun)

I have 6 in long trout on 6 mm pellets

The technical answer to your question of "what size pellet to feed the fish"....

Is that you should feed a pellet... that is half the size of the fishes "gape"..... totally open mouth....

It's always a good idea to mix the different gradings of pellets together as you increase pellet size...

This uses the older pellets... and makes the smaller ones available for the smaller fish...

My 200mm trout are quite happy to eat 2mm pellets

Here is a rough guide of what size pellet to feed Trout compared to their weight.
These figures come from one of the feed producers.

20 - 85gm 3mm
85 - 200gm 4mm
200 - 300gm 5mm
300 - 750gm 6mm
750 plus 7 or 8mm

I usually skip the 5mm and just continue feeding 4mm before going onto the 6mm. If in doubt you are better off with the smaller sizes as at least you wont lose any fish to them chocking on a pellet thats too large to fit down their throat. In nature often Trouts diets consist of large quantities of very small food items. I have caught many 2kg plus Trout where the largest food item inside them has been no larger than a 3mm pellet.

no worries mate, just flick me a pm and we can go from there
