U.S. Fisheries - Reports on Economics and Status of Stocks
April 29, 2014Fisheries of the U.S. - Economics and Status of Stocks Released TodayToday NOAA Fisheries released two important reports that continue to document positive trends in the sustainability of U.S. federally-managed fisheries--Fisheries Economics of the United States 2012 and the Status of U.S. Fisheries 2013. Together, these two reports highlight the strength of our federal fisheries as responsibly managed and underscore the broad and positive economic impacts that commercial and recreational fishing contribute to the nation's economy.In 2012, U.S. commercial and recreational saltwater fishing industries generated more than $199 billion in sales impacts, contributed $89 billion to gross domestic product, and supported 1.7 million jobs in U.S. marine fishing and across the broader economy.With regard to the status of our nation's federal marine fisheries, in 2013, 91 percent of assessed stocks/complexes were not subject to overfishing and 83 percent not overfished. This underscores the strength or the U.S. fisheries management system and the significant progress that collectively NOAA Fisheries, the regional fishery management councils and our stakeholders have made to end overfishing and rebuild our nations' fisheries.For full details on each report visit us online.Warm Regards,Laurel BryantChief, External AffairsNOAA Fisheries CommunicationsLaurel.Bryant@noaa.govwww.nmfs.noaa.gov
Lowly squid tops king salmon as Monterey's top cash fishery
More than 6 percent of California's seafood haul comes from the Monterey area, a region with a deep history of commercial fishing. Last year, catches of the humble squid generated about twice as much cash as the kingly chinook salmon.We've crunched the numbers to rank the top 10 commercial fisheries in the coastal fringes of Silicon Valley, which you can peruse below.

A super El Niño on the way? Subtle signs emerging
Mashable’s Andrew Freedman has penned an intriguing and important piece suggesting the possible El Niño in the pipeline may be a doozy, comparable to the strongest ever recorded:Since climate forecasters declared an “El Niño Watch” on March 6, the odds of such an event in the tropical Pacific Ocean have increased, and based on recent developments, some scientists think this event may even rival the record El Niño event of 1997-1998.Recall an El Niño event is an episodic warming of the eastern tropical Pacific ocean, which often has worldwide weather implications.Freedman interviews two scientists, Eric Blake from the National Hurricane Center and Paul Roundy from SUNY-Albany, who see early indicators reminiscent of the development stages of past whopper El Niño events.One important possible indicator of the lead up to an El Niño is a reversal in the trade winds observed in the equatorial Pacific, from a prevailing easterly (from the east) to westerly (from the west) direction. In recent weeks and months, there have been strong westerly “bursts”.Read the full article here.
Oceana bycatch report first salvo in next NGO campaign to restrict fisheries
Oceana has released a report on the nine dirties US fisheries in terms of bycatch to great media fanfare. "Anything can be bycatch,” said Dominique Cano-Stocco, campaign director at Oceana. “Whether it’s the thousands of sea turtles that are caught to bring you shrimp or the millions of pounds of cod and halibut that are thrown overboard after fishermen have reached their quota, bycatch is a waste of our ocean’s resources. Bycatch also represents a real economic loss when one fisherman trashes another fisherman’s catch.”“Hundreds of thousands of dolphins, whales, sharks, sea birds, sea turtles and fish needlessly die each year as a result of indiscriminate fishing gear,” said Amanda Keledjian, report author and marine scientist at Oceana. “It’s no wonder that bycatch is such a significant problem, with trawls as wide as football fields, longlines extending up to 50 miles with thousands of baited hooks and gillnets up to two miles long. The good news is that there are solutions – bycatch is avoidable.”This is not the language of scientists seeking to lower bycatch. It is a call to arms to shut down fisheries.Bycatch issues in fisheries are not new. US fishery managers have spent huge amounts of time addressing bycatch.For example, one of the key functions of fisheries observers is to accurately record and document bycatch, so that impacts on stock are understood and included in fishery management decisions.Read the full article here.
World's oceans hold 30 times more fish than believed
Pew research by an international team of marine scientists suggests that the global biomass of fish is 30 times more than the accepted estimate, contradicting previous beliefs about the biomass of fish in the world's oceans.The team investigated mesopelagic fish that tend to dominate the world total fish biomass. Mesopelagic fish are open-sea species that occupy the mid-depth of the oceans from 200 metres to 1,000 metres below the surface.They are small, often migrate to the surface at night, and have remarkable senses - in vision and in sensing pressure and motion - which enables them to avoid nets and fishing gear.In a report in Nature Communications, the scientists say they had not been able to accurately estimate the biomass of fish in the past because of the difficulties in sampling and the fact that available estimates were based on false premises.To overcome these problems, the researchers analysed acoustic observations collected during the Malaspina 2010 Circumnavigation Expedition. Their calculations showed that the previous estimate needed to be revised to a higher biomass of at least one order of magnitude.This means there could be more than 3,000 million tonnes of mesopelagic fish in the ocean - a stock still untouched by fisheries and possibly increasing because of the decline of their main predators, tuna and swordfish.Read the full article here.
Assessing the Vulnerability of Fish Stocks in a Changing Climate
What is the Fish Stock Climate Vulnerability Assessment?NOAA Fisheries, in collaboration with the NOAA Office of Oceanic and Atmospheric Research - "Earth System Research Laboratory, is finalizing a methodology to rapidly assess the vulnerability of U.S. marine stocks to climate change. The methodology uses existing information on climate and ocean conditions, species distributions, and species life history characteristics to estimate the relative vulnerability of fish stocks to potential changes in climate.Climate change is already impacting fishery resources and the communities that depend on them. Scientists are linking changes in ocean temperatures to shifting fish stock distributions and abundances in many marine ecosystems, and these impacts are expected to increase in the future.To prepare for and respond to current and future changes in climate and oceans, fisheries managers and scientists need tools to identify what fishery resources may be most vulnerable in a changing climate and why certain fish stocks are vulnerable. By providing this information, the methodology will be able to help fisheries managers and scientists identify ways to reduce risks and impacts to fisheries resources and the people that depend on them. These kinds of climate change vulnerability assessments are increasingly being used to help assess risks to terrestrial and freshwater natural resources and man-made structures such as buildings and bridges.Read the full article here.
El Nino predicted to return this year with implications for weather and fisheries
A warming of the central Pacific Ocean this year will change weather worldwide, US forecasters predict.The warming, called an El Nino, can mean an even hotter year coming up and billions of dollars in losses for food crops.Australia and South Africa should be dry while parts of South America become dry and parts become wet in an El Nino. Peru suffers the most, getting floods and poorer fishing.But it could bring good news for some parts of the planet, leading to fewer Atlantic hurricanes and more rain next winter for drought-stricken California and southern US states. It could also bring and a milder winter for the frigid US north next year, meteorologists sayThe National Oceanic Atmospheric and Administration issued an official El Nino watch today. An El Nino is a warming of the central Pacific once every few years, from a combination of wind and waves in the tropics. It shakes up climate around the world, changing rain and temperature patterns.Read the full article here.
