Fishing Methods
There are a wide variety of fishing methods used. Each has it own environment impact that varies on intensity. The table below highlights a fishing method along with its environmental repercussions.
Method | Equipment uses | Type of fish | Environmental Impact |
---|---|---|---|
Pole/troll | Fishing rod/pole and bait | Open ocean swimmers to bottom dwellers | Low environmental impact. Reduced chance of bycatch |
Purse seining | A large net is used to surround fish. The bottom of the net is pulled close to push the fish to the middle | Schooling fish | Higher chance of bycatch |
Gillnetting | Uses a system of nets with floats and weights. The nets are anchored to the sea floor and allowed to float at the surface | Sardines, salmon, cod | Animals cannot see the net therefore, they swim into it and are tangled. Huge risk of bycatch. |
Longline fishing | Fishing line cast out from the boat. Can range from one mile to 50 miles. | Pelagic fish | Higher risk of bycatch. Fisherman use weights to sink their lines, which reduce the risk of bycatch. |
Traps and pots | Wire or wooden cages attached to the sea floor; fishing weirs | Lobsters, crab, shrimp | The traps keep the fish alive. Lower chance of bycatch. |
Trolling | Line towed behind the boat | Salmon, mahi-mahi, tuna | Release bycatch |
Harpooning | Harpoon | Large pelagic fish | Fisherman have to visualize prey. No chance of bycatch. |
Trawls and dredges | Use huge nets that can either drag on the bottom of the sea floor or in the middle of the surface or the floor. | Pollock, cod, flounder, shrimp | Large number of bycatch. Can damage the sea floor. |

Famous quotes containing the words fishing and/or methods:
“The hill farmer ... always seems to make out somehow with his corn patch, his few vegetables, his rifle, and fishing rod. This self-contained economy creates in the hillman a comparative disinterest in the worlds affairs, along with a disdain of lowland ways. I dont go to question the good Lord in his wisdom, runs the phrasing attributed to a typical mountaineer, but I jest caint see why He put valleys in between the hills.”
—Administration in the State of Arka, U.S. public relief program (1935-1943)
“We are lonesome animals. We spend all our life trying to be less lonesome. One of our ancient methods is to tell a story begging the listener to sayand to feelYes, thats the way it is, or at least thats the way I feel it. Youre not as alone as you thought.”
—John Steinbeck (19021968)
