A fisherman finds flocks of fish floating dead in Texas City. On a boat on Moses lake Mark Raby was fishing and suddenly, literally, ran into droves of dead fish drifting in the water. Raby and his wife were so alarmed they saved a bag of dead fish for future lab testing, if necessary, and to figure out if whatever killed the fish can also harm humans. "We saw a bunch of small dead fish but the thing that was so amazing there were millions of them. Acres and acres of dead fish," explains Raby. Another resident says she has lived here six years and this is the largest fish kill she has ever seen.
So what is it? What killed the fish.
The guys over at Texas Parks and Wildlife have solved the mystery on Moses Lake for us. We're told it's likely a case of low dissolved oxygen in the lake. It's something that tends to happen in the heat of summer and small fish such as Menhaden get trapped in that low oxygen zone and die.
According to the Parks and Wildlife folks larger fish can detect the lack of oxygen and swim away but I'm told state biologists are looking into the matter to be sure.
So has Raby been fishing here since spotting the streams of dead fish? "No I haven't. I haven't fished since that day but I probably will. We would be hesitant to eat them until we really got to the bottom of this," adds Raby.
Whatever this is is clearly fatal to fish but is it harmful to humans? According to Texas Parks and Wildlife the fish are likely dying due to low oxygen in the lake and that isn't anything that will be hazardous to humans.
