Can Hag Fish gloop be useful to humans?

May 19, 2016 Marine Science

The carrion-eating hagfish has been described as the “vacuum cleaner of the ocean”. But it also has another claim to fame: it can see off its attackers in a puff of slime. Zurich scientists are researching how this fast-forming hydrogel could be harnessed for human use. Jawless and boneless, the hagfish is a rather ugly-looking marine creature that has been around for more than 300 million years. So why are the hagfish of interest to researchers at the lab? The answer is in the creature’s slime. When the hagfish is attacked or stressed it secretes vast amounts of the substance as a defence mechanism – as this shark finds out in this clip. It has to back off or face suffocation. “Hagfish slime is special in many ways,” doctoral student Böni told swissinfo.ch. “It’s the most dilute hydrogel known today. It consists of 99.996% water which is a world record.” Read the article here 13:46

The New England groundfish debacle (Part III): who or what is at fault? Nils E. Stolpe/FishNet

It took me a while to decide how to most accurately describe the situation that has been visited upon the New England fishing communities that are and since colonial times have been dependent on the groundfish fisheries.

NILS STOLPE: The New England groundfish debacle (Part IV): Is cutting back harvest really the answer?

While it’s a fact that’s hardly ever acknowledged, the assumption in fisheries management is that if the population of a stock of fish isn’t at some arbitrary level, it’s because of too much fishing. Hence the term “overfished.” Hence the mandated knee jerk reaction of the fisheries managers to not enough fish; cut back on fishing. What of other factors? They don’t count. It’s all about fishing, because fishing is all that the managers can control; it’s their Maslow’s Hammer. When it comes to the oceans it seems as if it’s about all that the industry connected mega-foundations that support the anti-fishing ENGOs with hundreds of millions of dollars a year in “donations” are interested in controlling.
