The Mystery of the Missing Fish

It wasn’t quite the mystery of whether aliens landed in Area 51, but around Casa Melamud everyone was perplexed and spending considerable brainpower trying to solve the case of the missing fish.
    It is my habit to go out every evening after dinner and cast my pole from my dock, trying to catch fish for our lunch or to bait my crab traps. I have been consistently getting a handful of medium-sized white perch. Unhooking the fish, I’d tossed them on the dock. But when I went to pick my catch, there were fewer fish than I remembered. This was happening evening after evening. I heard nothing and saw nothing. The fish were just disappearing.
    My wife was sure I was miscounting; she called the missing fish a “senior moment.” Maybe the first time, but not night after night. It’s easy to remember whether you caught two or three fish.
    My daughter thought a feral cat was stealing the fish. This sounded reasonable, except that in the almost four years we have lived in this house, I had never seen a cat outside, feral or otherwise.
    For a better explanation I went to the mother of all knowledge: Google. Search results made the answer clear.
    Aliens are no longer slaughtering and abducting cows. They are eating healthier as they are now abducting fish. I found some compelling arguments, but I reasoned that if I were an alien looking for fish, I would be after sushi-grade tuna, not white perch.
    Finally, I posed the question on the fishing bulletin board I participate in. About 15 other members chimed in with their thoughts on our mystery. Seven said all fishermen are liars, so none of this was happening. Seven told me I was using the wrong lure. If I used the one they recommended, I would catch enough fish to not care about a missing few. One supported the alien abduction theory.
    I was resigned to living with my mystery. But one of the keys to success is luck and timing. About a week after the mystery first posed itself, I happened to turn my head at the precisely right moment, and I saw my answer.
    Who’s got my missing fish?
    See for yourself.
