BRUSSELS (Reuters) - Europe's trawlermen should cut back drastically next year on trawling for herring in the North Sea as juvenile herring are not maturing properly, a respected group of international scientists warned on Tuesday. Serious reductions were needed in next year's catch due to worrying falls in the area's herring stock, the International Council for the Exploration of the Sea (ICES) said, adding that the EU's quota should be slashed by nearly 50 percent for 2007....

BOSTON -- A group of Boston-area scientists has come up with what they say is a better way of tracking and estimating fish populations, which in turn could change the way fishery regulators manage the resource. The new sonar technique is able to scan for fish over an area a million times larger than what could previously be studied, the report's lead author said. "I've had these dreams where you are floating in the water in the darkness and look down and suddenly see everything; that's what...

By Alister Doyle, Environment Correspondent OSLO -- Thousands of salmon, tuna and other fish with electronic tags are revealing mysterious Pacific Ocean migration highways that may give clues about how to rebuild dwindling stocks, scientists said on Wednesday. Marine experts also found 78 new species of fish in 2005 along with scores of other creatures ranging from a 3-meter (10 ft) rocket-shaped jellyfish in the Arctic to a tiny carnivorous sponge in the South Atlantic. "Fish with chips" --...

SEATTLE (AP) -- With a record number of dead seabirds washing up on West Coast beaches from Central California to British Columbia, marine biologists are raising the alarm about rising ocean temperatures and dwindling plankton populations. "Something big is going on out there," said Julia Parrish, an associate professor in the School of Aquatic Fisheries and Sciences at the University of Washington. "I'm left with no obvious smoking gun, but birds are a good signal because they feed high up...

SAN FRANCISCO (AP) -- Each winter, schools of silvery herring pass beneath the Golden Gate Bridge on the way to drop their eggs in the lushly vegetated corners of San Francisco Bay. In recent years, however, scientists have worried about the health of the bay's herring population. Fishermen also have found it increasingly difficult to earn a living in the bay's last significant commercial fishery, but argue the herring population is healthy and state restrictions are the cause of their woes....

How a flock of birds or school of fish may go in a single direction without having a permanent leader is a mystery of social organization. But adding a mechanized component to the question raises the possibility of robotic swarms which may lack much in the way of social skills or leadership qualities. Astrobiology Magazine -- A study led by Princeton biologists has revealed a remarkably simple mechanism that allows flocking birds, schooling fish or running herds to travel in unison without...

The Atlantic herring, Clupea harengus, is the one of the most abundant species of fish on the planet. They can be found on both sides of the Atlantic Ocean congregating together in large schools (or swarms). They can grow up to 17.72 in (45 cm) in length and weigh more than 1.1 lb (0.5 kg). They feed on copepods, krill and small fish, and their natural predators are seals, whales, cod and other larger fish. The Atlantic herring fishery has long been an important part of the economy of New...

The Blue runner (Caranx crysos) is a fish found along the coastlines of the Atlantic Ocean, mostly in the inland waters of the east coast of North America and the west coast of Africa. The fish has a rounded body shape and can grow to up to 27.56 in (70cm) long and weigh more than 11 lb (5kg). The body is silvery blue in color with a large eye. Blue runners are known as very fast and aggressive fish, traveling in schools and eating smaller fish and invertebrates. Schools may also pick...
