how does fishing affect the water?

Question

homework help!!how does fishing affect the water quality?

Answer 1

I would have put it another way. How does the water affect the fishing? It seems to me that this is a more pertinent question.

Answer 2

Speaking as one who went to graduate school on an assistantship sponsored by the state Department of Natural Resources - I would say the answer to your question can go either way. Question is which outweighs the other. Some negative impacts include lead sinkers that get eaten by and poison waterfowl (not as serious as made out to be), fuel from boat motors and occasional spills does get into the water, and of course the many non-indigenous plants and animals that are easily transported on boats and fishing gear (spiny water flea, zebra mussels, Eurasian water milfoil, etc).

However you can look at it this way - no fisherman wants to be casting his line into a cesspool. Fishing is a multi-billion dollar industry worldwide - with much of that profit going directly back into the environment through various cleanup and education efforts, research projects, etc. Likewise much of the licensing fees go toward efforts to maintain or improve water quality. As an example - there are countless lakes throughout the country and the world which have been cleaned up, waste treatment systems installed to replace leaky septics, etc - ALL FOR THE IMPROVEMENT OF WATER QUALITY. How the local fishery responds (usually an improvement) is a guage as to how well these efforts have worked. And an improved fishery means more dollars spent by fishermen - more dollars for continued improvement.

Fishing is a way to enjoy nature, and fishermen will do what they can to enhance and preserve the outdoors. The benefits definitely outweigh the incidental negatives.

I mentioned my education was partially funded by the state DNR. Whenever you buy your fishing or hunting license - the seller should ask if you want to make a $1 donation for research - please make the donation - you'll be helping to fund state and/or student research projects which will ultimately help the environment.

Answer 3

Fishing in itself does not affect water quality. Think of it. How can dropping a monofilament line into water affects its chemical and physical qualities? One has mentioned the use of lead sinkers. Lead sinkers have not been used in years.

Now, if you are thinking of commercial fishing and its affects on water quality, then you are probably asking how commercial fishing affects the habitats of fish. Most net fishing also has no affect on water quality. However, the use of drag-nets to fish for ground fish does damage the sea floor habitat.

Movements are on to limit the areas fished, the number of nets and the number of hours that drag-netters are able to fish.

And, has been pointed out, the fishermen themselves pay fees that lead to research, recovery, and enhancements of fish and their environs. To end fishing, would be to end fisheries.

Answer 4

it kills the fish, and the fish eat the dirt in the water

Answer 5

the boat that carry the fisher men out into sea the can let out oil in the sea and can cause the fish to die

Answer 6

fishing and water are corelated to each other
