From , releases of hatchery-raised Atlantic salmon smolt to supplement natural production in the streams of the Gulf of Maine resulted in adult spawning returns of approximately 0.
This low return rate is the result of numerous factors including high mortality in the river from downstream passage barriers and low marine survival. Fish passage is essential for adult salmon to be able to travel upriver to spawn and for salmon smolts to be able to travel down river to reach the sea. A fish ladder, or fishway, is often constructed to help salmon swim upstream around a dam or a natural barrier that might prevent or impede progress to spawning grounds.
Downstream passage of migrating smolts and some post-spawned adults past barriers is sometimes provided by constructing a bypass structure or by allowing sufficient amounts of water to spill over a dam. Before the decline of Atlantic salmon, anglers competed annually to land the largest spring salmon. The tradition was suspended due to low salmon abundance in President George H.
Bush was the last President to receive a Presidential salmon.

Why are fish ladders constructed? Because they may become sexually mature anywhere between 2 and 7 years old, the size of the spawning fish can vary greatly. A sexually mature 2-year-old fish will likely weigh less than 4lbs, but a 7-year-old mature fish can easily weigh more than 50lbs! King salmon return to the freshwater river where they were spawned between May and July.
Each river usually has only one run of King salmon. Fresh-water lakes, streams and their estuaries are the spawning and rearing grounds for King salmon. In the ocean, juvenile fish are found where the bait fish are, generally between 30 and 60 feet deep. Tackle: Saltwater Trolling: Rod: An ft, lb rod with a bait caster reel. The ideal rod has a good back bone a flexible tip. This makes it strong enough to land a big fish in a reasonable amount of time, while still letting you feel the fish, and enjoy a good fight.
Mature Chinook Salmon eat a different range of food to parr and fry. Mature adults feed primary on other fish species, avoiding smaller foods such as insects and small fish. Smolts and young adults still consume large zooplakton, herring, pilchard, sandlance and other fishes, squid and crustaceans. The myth came about because of the reproduction cycle. The element of truth behind this myth has to do with reproduction. I came across this little fact the other day and it made me think for a while.
Everyone knows that there are more sheep than people in New Zealand. In fact any mid-size city in North America has more people in it than the entire country of New Zealand. While tiny, the country has stunning beauty. You can see this in some of the movies like the Lord of the Rings trilogy, which was filmed in the south.
Ok, I ramble on. New Zealand is the worlds largest producer and market supplier of the Chinook salmon, though they call it King Salmon. In , New Zealand managed to export a staggering 5, tonnes of Chinook Salmon. This is not surprising really knowing how important fish is in their diet.
