The groundhog was coming under my new fence from his den on the other side, under my neighborâs shed. I got him/her with a head of lettuce too brown for me to eat. I wedged rocks and positioned the trap so when exiting the hole on my side of the fence he had no where to go but into the trap. He ate all the lettuce.
The average weight of the fish (weight in a sample / no. of fish in sample); Feed Rate which is a percentage of its body weight (this data could be gotten from a feed chart of a feed production company or study materials) Feed ration per pond= average fish size (weight) x feed rate (%) x total number of fish in the pond. E.g. If an African catfish of 180 grams requires a ration of 2.5% of its body weight, how much food should it be given per day?
Fish should be fed no more than three times per day. In cooler water they should only be fed once per day, if that. In much warmer water, three times per day is not 'crazy' however, you have to be wary of bacterial blooms (cloudy water and low oxygen levels) if you feed heavy and there's a lot of waste. Fish should be fed for about five minutes per feeding. If they don't come up and eat voraciously, they are telling you that they are too cold, or too warm, feed light. If they come up and hit hard you can sprinkle food on the water for five minutes as long as there are fish there to carry it off.
