The <a href="http://blueocean.org/">Blue Ocean Institute</a> and <a href="http://www.montereybayaquarium.org/cr/SeafoodWatch/web/sfw_factsheet.aspx?gid=49">Monterey Bay Aquarium Seafood Watch</a> both rate it "green" -- that is, one of the most sustainable fish. "Abundance of salmon, particularly Pink and Sockeye, is high in Alaska due to good management and healthy habitat," writes Blue Ocean. "The majority of salmon is caught with purse seines, followed by gillnets and troll gear. These fishing methods cause little habitat damage and result in moderate levels of bycatch, typically other fish."<br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg3PNCt5SFmEZ3C1TxF9mT_swyQWRRRSFmH-waIZmLoCORJNhoV9b6Hbe5_I5l3CpyfqOnifaSPcP1ZMy9sZZZ2JJ24TCBRgljDqQaOZbcxUuPVwyxU3CzlZXN5ZK0li2OFQEBhmUXldjVZ/s1600/tlingit-food.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg3PNCt5SFmEZ3C1TxF9mT_swyQWRRRSFmH-waIZmLoCORJNhoV9b6Hbe5_I5l3CpyfqOnifaSPcP1ZMy9sZZZ2JJ24TCBRgljDqQaOZbcxUuPVwyxU3CzlZXN5ZK0li2OFQEBhmUXldjVZ/s400/tlingit-food.jpg" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Tlingit food, display in Sitka National Historical Park</td></tr></tbody></table>The Tlingit tribes that have lived in southeast Alaska for centuries depended on salmon, which they preserved by smoking or drying to make a variety of long-lasting foods. Traditionally, they also ate other seafoods, including seal meat, and used seal fat to preserve berries. Their fishing and hunting practices were very sustainable and efficient, but of course the population was small and there were no exports.<br /><br /><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: left; margin-right: 1em; text-align: left;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3-sSJ7V0uCtRWmtkoGRabd6ZMbAA4D2KVRHWEA7qgmM0MhC_EqbfpBGBiyecJ-7ob5Hzaqja0EVoyhdwAvP5t4J9hn5LhHgJLFPxbZFqXKLt18FbUa3ST-afboRAaV_7XH1BsOamwPexM/s1600/petersburg6128.jpg" imageanchor="1" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" height="211" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3-sSJ7V0uCtRWmtkoGRabd6ZMbAA4D2KVRHWEA7qgmM0MhC_EqbfpBGBiyecJ-7ob5Hzaqja0EVoyhdwAvP5t4J9hn5LhHgJLFPxbZFqXKLt18FbUa3ST-afboRAaV_7XH1BsOamwPexM/s320/petersburg6128.jpg" width="320" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Boats in Petersburg (Len's photo)</td></tr></tbody></table>Now the Alaska fisheries are among the most productive anywhere, and their products both fresh and preserved, go all over the world. In view of the utter depletion of other fishing grounds, such as Atlantic cod, it's encouraging that Alaska fisheries still seem sustainable.<br /><br />Petersburg, which we visited, has only a few thousand people, but ranks sixteenth among US fishing ports, with a total of 101 million pounds of seafood, worth $65 million, caught in 2011 (<a href="http://www.ufa-fish.org/CFF/2012/25.Petersburg%20Community%20Fish%20Facts%20V%202012.1.pdf">source</a>). When we visited, most of the salmon boats were out at sea where the salmon were running.<br /><br /><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: left; margin-right: 1em; text-align: left;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjASAy4A-Mj2AqstZU3oSGjlwGMLILb8RoL7Y6O7EnYlmPp31UFPYrRuJ9lL8Juft2At7tWLVDQwpJk3x0xhpf-J8wGRf4Q09LqjSaCh9SVHUcJeRUpyNNFY5VjxVFxFwkdBlRFh8LnltpM/s1600/petersburg6160.jpg" imageanchor="1" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" height="211" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjASAy4A-Mj2AqstZU3oSGjlwGMLILb8RoL7Y6O7EnYlmPp31UFPYrRuJ9lL8Juft2At7tWLVDQwpJk3x0xhpf-J8wGRf4Q09LqjSaCh9SVHUcJeRUpyNNFY5VjxVFxFwkdBlRFh8LnltpM/s320/petersburg6160.jpg" width="320" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Petersburg Alaska (Len's photo)</td></tr></tbody></table> Petersburg fishermen also catch other Alaska seafoods rated environmentally responsible: Dungeness crab; red, blue, and golden king crab; pink shrimp, Dover and rock sole, and sablefish. Halibut, another valued fish, is abundant in Alaska. Monterey rates it green, but Blue Ocean classifies it as yellow (not as desirable) because of the danger of mercury.<br /><br />As I wrote yesterday, we tasted several of these, as well as some type of rockfish (which I suspect is only available locally so the Alaska version doesn't appear in the ratings).<br /><br /><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjh8Ei9JucMC45pIjcWR6fRZcYKPcZ4JrPi8R95xbYMlscXlL6_ww0f48dn45ebwNg_Dk8lI9UJwd5FtLPOpLZXzm_Dtu8jLQ8U0PvaVIJej4UhycPDjAvP2kotOAC96B5F21oL_HLIBN5o/s1600/petersburg3304.jpg" imageanchor="1" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjh8Ei9JucMC45pIjcWR6fRZcYKPcZ4JrPi8R95xbYMlscXlL6_ww0f48dn45ebwNg_Dk8lI9UJwd5FtLPOpLZXzm_Dtu8jLQ8U0PvaVIJej4UhycPDjAvP2kotOAC96B5F21oL_HLIBN5o/s400/petersburg3304.jpg" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Cannery on the wharf in Petersburg</td></tr></tbody></table>Now that I'm home, I am definitely missing the wonderful flavors of many types of fresh fish. However, I do try to comply with the suggestions of the two rating agencies that suggest responsible ways to eat seafood; as it happens, I shop for fish at Whole Foods which has partnered with both of them and committed to sell only recommended fish.<br /><br />Both the Blue Ocean and Monterey ratings agree with the fisherman in Petersburg in condemning farmed salmon for its dangers to the environment. In contrast, by inspecting a variety of farms, Whole Foods claims to have identified responsibly and safely designed salmon farms that satisfy higher standards. These farms use "carefully monitored, low-density pens and tanks without antibiotics, pesticides or added growth hormones." They also are believed to prevent the escape of fish or their toxins and diseases into the wild.

Last week in southeast Alaska we hiked and kayaked beside streams crowded with salmon swimming upstream to spawn and die. We saw salmon jumping in the waterways near our ship, the Sea Bird. We watched bears snatching salmon from the streams and eating their favorite parts. We heard lectures on the natural history of salmon and on its importance to the local native people, the Tlingit. We visited a fishing village, Petersburg. And several times, we ate local smoked, cured, or fresh salmon.<br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhSr_sXvyAZm-Cyis2Dsuhb7VBVpjpF3t2tfWEJJubSgSoGvkW24GvzTUAnZZtB9Sz9ZLohf1AQyccYmn8V6CypbUNHNCS1wVi-4KgzXrOKGUEvQhAjEa_aqrF53-w5X96sME9LU75UX95g/s1600/salmon-len.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="427" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhSr_sXvyAZm-Cyis2Dsuhb7VBVpjpF3t2tfWEJJubSgSoGvkW24GvzTUAnZZtB9Sz9ZLohf1AQyccYmn8V6CypbUNHNCS1wVi-4KgzXrOKGUEvQhAjEa_aqrF53-w5X96sME9LU75UX95g/s640/salmon-len.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Salmon swimming up a stream (Len's photo)</td></tr></tbody></table><br /><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: left; margin-right: 1em; text-align: left;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMf2QaSOmT3tfZInJkxNARhyme11AKIV6-m8CDIJf8ls6T-smM36n3xSKtFgSwEw3EBlowqV2PUiHkuyQ64aKKMYJSmufHZBp-6IhGZax3vzm6Y7amljHU51kjIGeS9O8CQaNUxd1KDlBt/s1600/salmon3.jpg" imageanchor="1" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMf2QaSOmT3tfZInJkxNARhyme11AKIV6-m8CDIJf8ls6T-smM36n3xSKtFgSwEw3EBlowqV2PUiHkuyQ64aKKMYJSmufHZBp-6IhGZax3vzm6Y7amljHU51kjIGeS9O8CQaNUxd1KDlBt/s400/salmon3.jpg" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Dead salmon in the stream</td></tr></tbody></table>The salmon, we learned, are not just good for human food. They play an incredible role in forest ecology, bringing the nutrients they ate while at sea back to the forest where they were born: "When they return to spawn, salmon become a veritable conveyor belt for nutrients. For example, an adult chum salmon returning to spawn contains an average of 130 grams of nitrogen, 20 grams of phosphorus and more than 20,000 kilojoules of energy in the form of protein and fat; a 250-meter reach of salmon stream in southeast Alaska receives more than 80 kilograms of nitrogen and 11 kilograms of phosphorous in the form of chum salmon tissue in just over one month."<br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: left; margin-right: 1em; text-align: left;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiuKLs75UQzZWyjDJl9886LhXXwluutl_m2MiaoOQ9LWnvxaBNOobJOOXNj_4uzva1MJmSmJnJRBCT0lg9AMIUg3VppGm_Le3RF-H5jYDD2qJchZh4GcxmDrFgv0u29P1mqMzWMAW2jVpLz/s1600/salmon4.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiuKLs75UQzZWyjDJl9886LhXXwluutl_m2MiaoOQ9LWnvxaBNOobJOOXNj_4uzva1MJmSmJnJRBCT0lg9AMIUg3VppGm_Le3RF-H5jYDD2qJchZh4GcxmDrFgv0u29P1mqMzWMAW2jVpLz/s400/salmon4.jpg" width="300" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Trees by the salmon stream</td></tr></tbody></table>Using all these nutrients, trees near salmon streams grow faster and larger than trees further away: beside the streams, "Sitka spruce take 86 years, rather the usual 300 years, to reach 50 cm thick." Growth rings in the trees are larger in years with good salmon runs.<br /><br />"And just as trees need salmon, salmon depend on trees. Every part of a tree participates in enriching a stream for aquatic life, from its tiny needles to its strong twisted roots. Streamside vegetation shades spawning streams, keeping developing eggs cool." -- from "<a href="http://www.adfg.alaska.gov/index.cfm?adfg=wildlifenews.view_article&articles_id=407">Why Fish Need Trees and Trees Need Fish</a>" by Anne Post.<br /><br />Distribution of the nutrients brought back from the sea by salmon is the job of the bears who fish in the streams and then spread the leftovers and their droppings nearby: "each adult female grizzly bear on the Kenai Peninsula in Alaska eats about 3000 lbs of salmon per year". The bears are much better nourished by salmon than by the berries and other plants or small animals that they feed on: "Grizzly bears that eat a lot of salmon are 80% larger, produce 25% more cubs, and live in populations that are up to 50 times denser than grizzly bears that fatten primarily on fall berries." -- <a href="http://nrs.wsu.edu/Research/Bear-Center/research/ecological.html">Washington State University Bear Center</a>.<br /><br />The entire quality of the stream is created by nearby trees, birds, animals, insects, and other plants. All are nourished by salmon that died after spawning or were partially eaten by bears; the salmons' bodies particularly feed the insect life that later feeds the growing salmon larvae.
