Steve M. :

Welcome to the PB forum. Can you provide when and what you stocked ? Time and size of fish and type. It would be unusual to have 3-4in LMB at this time of year under normal circumstances. It could be the result of a fall spawn which is unusual but can happen. If you have 3-4in. LMB they are not the original LMB you stocked (unless you just stocked them) so you must have had a spawn for them to show up. Growth rates vary but as a general matter a LMB spawned in March in the south will be 3in. by mid summer and 6in. by fall. They don't grow much during the winter but usually are about 8in. by their first birthday. These are averages and any pond can have a faster or slower growth rate depending on its productivity. New pond growth rates can be faster than normal.
