One of the local old timers told me a story today about the correlation between barometric pressure and "cow" feeding/grazing patterns. According to my local guy, the cows gaze and feed more aggresively at the same time at which the catfish are feeding more aggresively. So I looked up some information on cow eating etc. To make a long (and boring) story short, Cow digestion produces alot of methane gas from the digestion of cellulose. Now if barometric pressure affects the volume of a gas, higher pressure=smaller volume and vis-vera at the same temperature, then it would seem like during high pressure atmospheric conditions the volume of the gas in a cow's gut would be smaller. The smaller volume of gas would allow for more room for more food intake and the cow's would eat more.But most fisherman observe than falling barometric pressures produce the best fishing. Anybody know anything about this cow grazing and fish biting thing? anybody have any ideas?
