(12/13/2005) Coralreeffish.com, a coral reef fish research site, today announced the availability of a photographic web-guide to the late-stage larvae of coral reef fishes. The guide is aimed at both assisting researchers in identifying the myriad fish larvae that are caught in reef surveys and providing an overview of this intriguing, and often invisible, world to students and interested laymen.


Amazon drought continues, worst on record
(12/11/2005) The worst drought ever recorded in the Amazon continues according to an update from The New York Times. The drought has turned rivers into grassy mud flats, killed tens of millions of fish, stranded hundreds of communities, and brought disease and economic despair to the region.


Overfishing of fresh waters of serious concern
(12/1/2005) Systematic overfishing of fresh waters occurs worldwide but is largely unrecognized because of weak reporting and because other pressures can obscure fishery declines, according to an article in the December 2005 issue of BioScience.


U.S. fishing bycatch wastes 1 million metric tons of fish per year
(12/1/2005) A new study shows that for every five pounds of fish caught by U.S. commercial fisheries, one pound is dumped -- dead, dying and wasted.

Invasive species date back thousands of years
(10/13/2005) Much has been made of the economic impacts of recent biological invasions, but what are the implications of invasions in deep time? Luiz Rocha leads geneticists who time travel through ocean environments.

Africa Heats Up -- climate change threatens future of the continent
(10/11/2005) A series of recent studies have revealed a sobering future for the majority of Africa, a future predicated by undeniable and significant climate change. The threat traverses all levels of the environmental, social, political and economic spheres, from heightened socio-economic disparity to dwindling fish populations, from civil strife to desperate hunger. The greatest and saddest irony of this dark fate projected for the continent is that while Africa has the world's lowest levels of carbon dioxide and other greenhouse gas emissions, contributing the least to global climate change, it has been forced to bear the brunt of the phenomenon.


Link between ecosystems uncovered as fish in ponds help flowering plants

Summit explores how fish could feed Africa
(8/22/2005) This week policy makers, industry leaders, and development experts are meeting in Abuja, Nigeria to discuss the future of African fisheries and aquaculture.

Fish production, processing and trade provides employment for more than 10 million, while fish exports from Africa are worth US$ 2.7 billion annually. The following is a description of the summit from Fish for All, an initiative seeking to shape public policy on issues from issues as fish and development, fish and nutrition, health, livelihood, environment, gender, water, river basins and coasts, trade and economic growth.
