Red and Blue King Crab Research


The Alaska Sea Grant has announced that it will be giving $1 million to research why many red and blue king crabs in Alaska die during hatchery and other factors that influence the decrease in number of these crabs. Researchers have been working since 2006 on this task and have successfully increased the amount of crabs who reach juvenile stage from zero to 50 percent. Some researchers have proposed a nutrition deficiency for the cause of the numerous hatchery deaths and it is currently being investigated. Many tests, though, must be performed in order to discover the nutritional factors that can affect the health of the red and blue king crabs.
In addition, the Alaska Sea Grant has also given money to researchers who are attempting to test whether strontium, a naturally occurring element, can be used to trace king salmon back to their birthplace streams. Scientists believe that discovering their birthplaces will play a key role in maintaining the health and stability of both the king salmon and the surrounding human population.
I personally believe that these studies, both of them, could be very vital to the environment in Alaska and even the Arctic as a whole. If either of these two species become endangered or even extinct, then that could severely affect the stability of the Arctic and eventually the entire world climate and stability.

  1. I agree with your opinion that these tests are very vital. It makes sense that the nutrition factors could be depleting and not plentiful enough for the number of crabs that hatch causing most of them to not live. This very well could affect the Arctic environment as well as the food web that these crabs are in. If they keep depleting, then the things that eat them will have trouble and the things that they eat will begin to grow in number.

  2. I think that funding this type of research is very important. If studies like these were simply ignored, the Arctic food web could seriously be affected. I find it very interesting that one alteration in an ecosystem can have such a heavy impact--not only on the ecosystem itself, but also on the world as a whole.

  3. I completely agree with your belief. This goes not only against us, as humans, but also wildlife. Tests would be extremely beneficial in finding out if they are sick or if it is occurring naturally. I definitely wouldn't want to be eating something that was exposed to a bad area and could effect me!

  4. I am glad that money is being put towards researching this issue as I agree that this is an important issue to look in to for the Arctic food web, and ecosystem, if the crabs becomes endangered or extinct. I am happy that they were able to increase the number of crabs that reach the juvenile stage of their lives and that they are taking strides to do tests to fix the problem.
