NOAA: Ocean Acidification Rises, Shells Shrink

NOAA: Ocean Acidification Rises, Shells Shrink | GarryRogers Biosphere News | Scoop.it

"The oceans act as a “carbon sink,” absorbing vast amounts of carbon dioxide. Acidification occurs when amounts of carbon dioxide are dissolved into seawater, where it forms carbolic acid.

Scientists say the oceans are now 30 percent more acidic than they were at the beginning of the industrial revolution about 250 years ago.

Among the sea species most vulnerable to acidification are shellfish, because a build-up of acid in waters prevents species developing their calcium shells. Alaska’s salmon stocks are also at risk as one of the main ingredients of a salmon diet are pteropods, small shell creatures."

Garry Rogers's insight:

Greenhouse gas (mainly CO2) buildup in the atmosphere has a spreading web of consequences. The tentacles of the web are spreading quickly, too quickly for species to adapt.  The human impact is more like a massive meteorite strike than the ice-age climate changes or the slower continental drift changes.

National Bycatch Strategy :: Office of Sustainable Fisheries

National Bycatch Strategy :: Office of Sustainable Fisheries | GarryRogers Biosphere News | Scoop.it

NOAA Fisheries is committed to minimizing bycatch in U.S. fisheries. While we've made great progress, there is more to do. We have developed a draft National Bycatch Reduction Strategy, and we want your input.

 

Efforts to address bycatch fall into six broad program areas.

 

1) Monitor and Estimate: We monitor and estimate the rates of bycatch and bycatch mortality in fisheries to understand the level of impact and the nature of the interaction.

2) Research and Development: We conduct and support research to improve estimates of bycatch rates, better understand the impacts of bycatch on species interactions and community dynamics, modify fishing gear, and develop mitigation tools to minimize bycatch and its impacts.

3) Implement and Manage: We work with partners to develop and implement domestic management measures and promote the adoption and implementation of international measures to address bycatch and its impacts.

4) Evaluate and Improve: We evaluate the effectiveness of science and management programs to determine whether programs achieve stated goals and identify needed improvements.

5) Enforce: We enforce fishery management measures and work with state, federal, and international partners to ensure compliance with all applicable laws.

6) Communicate: We communicate within the Agency and to stakeholders to maximize the impact of bycatch reduction efforts
