CO2 can stink its salad with salad, as the new study says


A new study by the North Atlantic Fisheries Research Center in Washington and NOAA shows the rise in carbon dioxide in the ocean that salmon detect smells.

"Their sense of smell is very important throughout their lives," said Chase Williams, the lead author of the study Global Change Biology Monday.

The salmon depends on the nose, to prevent prey, to find food, to attract a friend and to retrieve it where they grow up to grow and kill.

"The question of how potential chemicals in the oceans affect this sensorial function would definitely answer an important question," Williams said.

The study was also known as a koho salmon found in the Alsuk-Tatshenshini River in Yukon, and northwards in the Porcupine River system.

The ocean absorbs airborne carbon dioxide; which concentrates water, lowering the pH. Ocean is the acidification process.

The research group has analyzed salmon for small children in different tanks of different pH levels. The first tank was pH level from Puget Sound water, and other deposits predicted pH levels between 50 and 100 years.

The fish were kept for salts for two weeks depending on the surface of the salmon, and was used to respond to the predator's attack.

Aquatic fish responded by the current CO2 levels away from the smell, but they did not fish in the other two fish.

"Really … They are changing the way the brain is processing the signs that are really happening," Williams said.

Fish still smell their scents, but it's not dangerous.

Williams has said he does not know how to put things in such situations, but it's enough proof to prove it.

"The final proof is worrying," Williams said.

Williams tells how other species of salmon that talk about each other are like cohoes, and there is a good evidence that other species can respond to it. They are interested in something that Williams and his team are looking for in the future.

"Pacific Northwest is a large part of the salmon ecosystem, they are also very important culturally and financially," said Williams.

The acidification of the ocean can be increased in the salmon environments with the help of other agents, placing more species at risk, according to Williams.

"It shows that rising CO2 concentrations in CO2 emissions are becoming increasingly widespread in the oceans," Williams said.
