| | What are seamounts? | | | Seamounts are undersea mountains (usually of volcanic origin) rising from the seafloor and peaking below sea level. Underwater mountains of heights above 1000 m are considered to be seamounts, those between 500-1000 m as knolls, and those below 500 m as hills. A seamount tall enough to break the sea surface is called an oceanic island, e.g., the islands of Hawaii, the Azores and Bermuda were all underwater seamounts at some point in the past.

| Best Fish Guide 2007-2008 launched: More fish go red but some nearly green
by Forest and Bird Preservation Society, New Zealand, Forest and Bird Media Release 13 November 2007 |  |
| | Seven more species of fish have joined the red list of unsustainable fisheries, but several come close to earning a sustainability tick on Forest & Bird’s new Best Fish Guide. Today Forest & Bird launched its third Best Fish Guide to help consumers make the best choices for the sustainability of the marine environment when they buy fish. Forest & Bird Conservation Advocate Kirstie Knowles says it is disappointing to see that seven more fish species – red snapper, moonfish, striped marlin, blue shark, mako shark, porbeagle shark and lookdown dory - have joined the list of fisheries which are environmentally unsustainable since the guide was last compiled in 2005-06. On a more positive note, several species – kina [sea urchin], anchovy, pilchards, sprats and blue mackerel – are within just 1-2 points of making it into the green list of fisheries which are sustainable. Again, no species are ranked as sustainable, but with improvements to fisheries management we could potentially see some fisheries be ranked in the green list in future. | |
