For lakes across the Lower Mainland (or across most of BC actually), there are no distinctions between wild and hatchery stocked trout or char, so only the blanket daily quota of four trout (wild or hatchery) applies. Most fish released from the hatchery into lakes are not marked, so to an average angler whose only concern is to purchase a licence and keep fish within his or her limit, it makes no difference. There are exceptions to the regulations of course. At lakes where anadromous trout and char may return from streams, catch and release of wild trout and char applies. For example, pitt Lake, Morris Lake. For Chilliwack Lake, most anglers/guides who target char (bull trout) only choose to keep smaller fish and release larger fish as they are the drive of recruitment. Again, this is voluntary and would only happen if the angler is informed of the biological background of the species that he or she is targeting. If there is a particular lake where wild trout or char population becomes a concern due to blanket freshwater fishing regulations, then send an email to MoE. The local biologists should take a look at it to make changes if they determine that there is a need to.
