Apes
at which latitude would you expect to find the most abundant fisheries?

0 degrees latitude.
10 degrees latitude.
30 degrees latitude.
50 degrees latitude.
70 degrees latitude.

one of the key environmental problems addressed directly in the magnuson-stevens fishery conservation and management reauthorization act is

overfishing.
fishing techniques.
loss of biodiversity.
loss of ocean habitat.
increase in bioaccumulation in large fish.

70 degrees latitude.

Loss of ocean habitat.

Explanation:

First question:

The most common fishery are the wild fisheries, that tend to happen in cold waters, for example, in Alaska. So it is 70 degrees latitude.

Second question:

Magnuson-Stevens Fishery Conservation: Legal provision for promoting optimal exploitation of U.S. coastal fisheries, to provide conservation for the fisheries. So the enviromental problem tackled is the loss of ocean habitat.
