Why do eels have slime

Now, two Alaska biologists are testing the waters for a fishery with longliner in Southeast who were given a special permit to catch 60, pounds of hagfish for their studies. The slime has several functions — it suffocates predators, helps hunt prey by forcing them out of burrows and it lubricates entry into fish through the anus.

Studies by the U. Navy and other researchers has shown that the chemical makeup of hagfish slime is stronger than spider silk. Navy is using synthetic hagfish slime to produce a substance that is lighter and stronger than Kevlar. The slime also shows potential as an anti-foulant for ship hulls. And medical research has shown that hagfish slime heals burns quickly and may be used as microfibers for cell repair.

The Commission tracks chums, cohos, pinks, sockeyes, Chinook and steelhead trout in the North Pacific, Bering Sea and the Sea of Okhotsk, and also provides the venue for coordinating research and enforcement activities.

For , just over million salmon weighing more than two billion pounds were caught in those waters, less than recent odd-year averages. Salmon catches tend to increase in odd-numbered years when the most abundant species — pink salmon — tend to run higher. Last year the U. Russia took 38 percent of the North Pacific salmon last year nearly 77 million pounds , with all other countries in single digit percentages.

As usual, pink salmon made up the bulk of the commercial catch at 49 percent by weight, followed by chums at 29 percent and sockeyes at 19 percent.

These types of fish can generate electric currents within their own bodies, enough to stun a person or kill a small fish.

Some countries eat a delicacy called a slime eel, but these are not true eels either, even though they resemble them. When they are agitated, they do produce a coat of thick, slimy mucous. But they are actually known as hagfish. Actual eels are indeed slimy.

In fact, the phrase 'slippery as an eel' is often used to describe someone who is devious or elusive. This mucous is produced from the glands just beneath its scales.

The slime affects how much water that the fish can bring in and out of its body from the gills. Water is constantly pumped in and out in order to optimize the biochemical balance of its body, a process called 'osmoregulation'. The thinner the layer, the more water can move in and out. Some researchers believe that the amount of slime coating allows eels to move easily from seawater to freshwater without effect.
