North Carolina State University In a new study, fisheries researchers from North Carolina State University found that black sea bass (Centropristis striata) can usually survive the physical trauma that results from being hauled up from deep water then released at the surface. The finding is part of a larger study of the fish’s mortality rate, which will inform stock assessments designed to help ensure that the black sea bass fishery is sustainable. Black sea bass are bottom-dwelling...

GSMFC concludes that Gulf menhaden stock is not overfished, nor is overfishing occurring. Houston, Texas (PRWEB) November 18, 2013 The Gulf States Marine Fisheries Commission (GSMFC) has completed a comprehensive, three year stock assessment of the Gulf menhaden population and found that the stock is healthy and sustainable at current harvest levels. The assessment was conducted in coordination with the National Oceanic and Atmospheric Administration’s Southeast Data, Assessment, and...

Biologists from Kiel and Vancouver present a simple way to estimate Maximum Sustainable Yield Up to now, methods to estimate the maximum sustainable yield (MSY) of fish stocks are very complex and, as a consequence, expensive. However, Dr Rainer Froese, biologist with GEOMAR | Helmholtz Centre for Ocean Research Kiel (Germany) and Dr Steven Martell, biologist with the University of British Columbia (Canada) have recently presented a new, much simpler method to estimate the MSY. This method...

New Population Model Explains Historic Trends, Shows Importance of Ecological Interactions NOAA scientists have developed a population model for Atlantic herring that links herring population trends to the size of the haddock population. The model also provides evidence that egg predation by haddock can cause alternate stable population levels in Georges Bank herring.  These results have significant ecological as well as management implications. In a study published online August 8,...

A measure widely advocated as a means of assessing the health of marine ecosystems is an ineffective guide to trends in biodiversity, and more direct monitoring is needed, a new study has found. The findings "“ published this week in Nature "“ followed an examination of  whether changes in fishery catches reflect changes in the structure of marine food webs, and therefore are a suitable guide to assess the impacts of fishing on marine ecosystem health. CSIRO Wealth from...

Inaccurate conclusions may have been reached in many ecosystems The most widely adopted measure for assessing the state of the world's oceans and fisheries led to inaccurate conclusions in nearly half the ecosystems where it was applied. The new analysis was performed by an international team of fisheries scientists, and is reported in this week's issue of the journal Nature. "Applied to individual ecosystems it's like flipping a coin; half the time you get the right answer and half the time...

The most widely adopted measure for assessing the state of the world's oceans and fisheries led to inaccurate conclusions in nearly half the ecosystems where it was applied according to new analysis by an international team led by a University of Washington fisheries scientist. "Applied to individual ecosystems it's like flipping a coin, half the time you get the right answer and half the time you get the wrong answer," said Trevor Branch, a UW assistant professor of aquatic and fishery...

ALEXANDRIA, Va., May 5 /PRNewswire-FirstCall/ -- The Atlantic States Marine Fisheries Commission ("ASFMC") today received the results of the latest Stock Assessment Workshop for Atlantic menhaden at the Menhaden Board meeting in Alexandria, Virginia. Consistent with the prior two ASMFC stock assessments reports in 2003 and 2006, the new report concludes that the Atlantic menhaden stock is not overfished and that overfishing is not occurring. A review panel of independent experts...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
