According to the literature, among freshwater fish in the Philippines are largemouth bass, crappie, walleye, and bluegill which were introduced into the river systems in 1999. You could probably get more accurate information from your wife's extended family.
Enjoy your retirement and all that the Philippines has to offer.
Thank you sir, but my wife's family doesn't know if these fish are in the Philippines, they all salt water fish. I've searched Google and could not find any discussion regarding crappie, bluegill and bass. Is it Philippines to share that link for my research? Thanks again for the reply.
