question What have you found to be the best incentives to alleviate large numbers of bycatch in ocean fishing? Do large fishing boats wind up with a higher percentage of bycatch than smaller-scale fishing operations?    -- Angela Mallard, Telluride, Colo.

answer Bycatch control and reduction is an important conservation goal. In Alaska we have employed several different strategies to control and reduce bycatch. Some of these include bycatch caps where a fishery shuts down when a specified amount of bycatch occurs in a fishery. In other instances, we have required retention of all catch of certain species, forcing harvesters to look for ways to catch only the fish they want. Individual bycatch quotas can provide an individual harvester with incentives to minimize unwanted catch in order to maximize the catch of desirable species.

Interestingly, bycatch is not vessel-size specific. In some fisheries, larger vessels actually have lower bycatch rates than smaller vessels. In other fisheries, it is the other way around. It is important to develop bycatch controls tailored to the specific conditions of the fisheries. The bottom line, though, is to measure the amount of bycatch, put in place limits on the rate or amount, and then enforce the rules.

question What sort of debris do you find most while doing your coastal cleanups? What's the most unusual thing you've found?    -- Name not provided

answer We find everything under the sun. The biggest volume seems to be old fishing gear. We are taking a lot of samples to determine where it's coming from. Our preliminary look indicates that a substantial amount comes from Russian waters and is very old. Watch for more information on this when we get our marine-debris website up and running.

The oddest thing to me was a shopping cart from Brazil. Go figure.

question Alaska has done a fabulous job designating protected areas on land. Partly as a result, most of Alaska's land-based animals exist in fairly healthy populations. In contrast, Alaska has few designated protected areas in the marine environment, and the majority of Alaska's endangered species are marine animals. Marine protected areas have proved effective in many areas of the world, and they often benefit commercial fishing. If Alaska is to be perceived as a model for marine conservation, isn't it time that we get busy establishing a network of marine protected areas that equals our land-based conservation system?    -- Brad Meiklejohn, Eagle River, Alaska

answer Alaska has done a reasonably good job on land, but you miss the mark about what constitutes sound conservation practices in the marine environment. What works on land doesn't always translate into success if applied in the ocean. The marine environment is much more dynamic, especially in the Arctic and subarctic, where our marine environment is subject to forces often on a global scale. Drawing lines on a map often won't address the problem.

For example, many of the marine species you refer to are highly migratory, and the conservation problem arises from areas outside Alaska. A case in point is the short-tailed albatross, a highly endangered seabird. Driven to near extinction by hunting on their ancestral nesting islands off Japan, these birds now have only one nesting site, on the side of an active volcano. Marine protected areas will not do them any good. New nesting sites on more hospitable islands will. Our group is actively working to help in the efforts led by Japanese scientists to establish additional nesting populations. This is just one example. Endangered whales (decimated by whaling during the past century), some seabirds (pesticides, loss of nesting habitat), and sea otters (predation, changing ecosystem characteristics) all require conservation action but MPAs would not address the root issue.

Having said that, place-based conservation areas are appropriate in some instances. In the North Pacific, several of the terrestrial conservation units have marine waters within their boundary, thus affording some general protections to marine species. More to the point, though, the North Pacific Fishery Management Council has set aside nearly 400,000 square nautical miles to protect marine habitat and important species. This is a huge area.

Can more be done? Of course it can, if additional actions are needed. Management agencies like the council are continuously looking at the need for additional conservation measures including new or adjusted MPAs. But in our view, action to establish such measures needs to be driven by science, address specific conservation issues, have clear goals with measurable benefits, and have a sound monitoring and enforcement plan.

Most importantly, we have very healthy populations of fish in Alaska, and that is due to conservative management guided by science. Remember, there are no overfished stocks of fish in Alaska, where over half the nation's seafood is harvested.

question What's your favorite seafood meal? Are there any types of seafood you avoid because you're concerned about overfishing?    -- Name not provided

answer Salmon, halibut, crab -- you name it and we eat it! The best thing about Alaska seafood is that it is wild, it comes from the clear waters of the North Pacific, and it's sustainable. No overfished stocks up here.

I do avoid species like orange roughy and blue fin tuna because I am concerned about overfishing. Same with farmed fish, especially salmon. There are just too many potential problems.

question I'm mindful that it's best to eat local wild or organically farmed fish if possible. I'm aware that our local Californian fisheries are really stretched. So I'm wondering, do you think I should buy Alaskan fish down here in Los Angeles, or not? And if not, what do you suggest?    -- Ysanne Spevack, Los Angeles, Calif.

answer By all means you should buy Alaska fish if you can get it. And, believe it or not, flash-frozen or frozen-at-sea products are really good. Sometimes "fresh" really isn't. Check with your grocer or the restaurant before you buy. Good bets are halibut, salmon (my favorite is troll-caught king salmon from Southeast Alaska), king or snow crab (which should now become more available to the consumer because the fishery went from a derby fishery to a quota fishery), and smoked fish products. If you feel adventuresome and it's available, try smoked blackcod.

question A friend of mine, a naturalist in Alaska, recently told me that he thinks that overfishing of the Bering Sea fishery is the greatest environmental disaster happening that nobody seems to be paying any attention to. How do you respond to that?    -- Name not provided

answer I wish I could show you a graphic I have about the levels of fish harvesting in the U.S. waters of the Bering Sea, but the file is too big to send here. But to put in perspective, overfishing limit for the Bering Sea/Aleutian Islands in 2005 was around 3.5 million metric tons, and the catch was around 1.9 million metric tons. The overall biomass was roughly twice the overfishing limit.

What that means is that there are several buffers built into the harvest levels to ensure that overfishing does not occur. The NPFMC has a long track record of setting harvest levels at or below the levels recommended by the scientists. And it works. No overfished stocks, large areas of habitat protected, ecosystem considerations taken into account. We use hard caps, careful monitoring, and strict enforcement to make sure that what the scientists recommend, and the target levels set by the managers, are not exceeded.

I would recommend you go to the North Pacific Fishery Management Council website and look up the overall harvest levels there, as well as other information about how good management works.

question We've heard a lot about the effects of climate change on Alaska's glaciers and tundra, but what (if any) effects have you noticed thus far to the marine environment?    -- Name not provided

answer I personally think this is the big question. There is no doubt that ocean conditions are changing. Whether or not those are short-term phenomena or a long-term change remains to be seen. But harvesters are reporting that species are moving north, ranges of species are changing, and weather patterns seem different, as well as changes in ice cover in places like the Bering Sea.

One thing our organization is doing is developing a cooperative research program to bring state and federal scientists together with harvesters and other industry experts to look at a number of pressing fishery conservation issues. One thing we are looking at is the possibility of using fishing vessels as platforms of opportunity to carry oceanographic monitoring equipment. It could be an efficient and effective way to gather temperature, salinity, and other data from a wide area of the ocean for relatively little cost. I'm excited about this new program, and hope we can make a solid contribution to better understanding the marine environment.

question Since the technology exists to dramatically extend the life of hydraulic fluid or lubricating oil, why don't we require implementation of the "best available technology" to prevent the generation of this waste at sea? I know some of the cruise ships were dribbling oil out the back and got caught and fined. The waste oil is a problem and does not have to be if we could start adopting cost-effective new technologies to prevent pollution.    -- Chuck Mitchell, Center Harbor, N.H.

answer I agree with you. And a lot of fishing operations now recycle their oils. It's illegal to dispose of this stuff in the ocean and violators must be punished.

question Do you see Alaska moving from being a red state to a blue one?    -- Angela Mallard, Telluride, Colo.

answer Haven't a clue. I have always pondered what would have happened to Alaska if the Czar had not sold it. Look what happened with some of the other Russian provinces when the Soviet Union fell apart -- they get to print their own money. Of course, some folks think we do that with the oil dollars anyway.
