Fish eggs are sexy

...at least to female fish seeking a mate. Having a pack of offspring nearby is a good way for some male fish to find a mate.

Of course, some males can't be bothered with the real work, and have developed "fake" offspring that fool females into mating with the phony dads. The fakes can be elaborate appendages that look like eggs or baby fish.

Similar things seem to work for people. Women prefer men who like children and can identify them just by looking. But the good daddies don't get all the benefits. For short-term flings women choose manly men with high testosterone levels--again just by looking.

Fish thriving in Tortugas reserve

Five years after fishing was ended, fish are thriving in Florida's Tortugas marine reserve.

Scientists have found more fish and larger fish in the areas where no fishing is allowed. No great surprise, really, it's simple common sense.

But it's far from simple to get some areas closed to fishing. Some fishermen fight vigorously against all attempts to create marine reserves where no fishing is allowed.

I'm a fisherman and I accept the idea that some areas should be set aside for fish and not for fishermen. I wonder how many fishermen would accept closure of some areas where fish can thrive in the absence of fishing?

Hawaiian ocean reserve success

Stunning success is rare for conservation, so I'm thrilled to point to the new Northwest Hawaiian Islands marine reserve!

Renowned environmentalist George Bush signed an order making the reserve off limits to activites that can harm ocean ecosystems. The limits are strict and sweeping, and they take effect immediately.

Wow.

I repeat, WOW!

This is ocean conservation done right. I hope it's just the beginning in reversing the tide of ocean decline. This has taken a lot of work by a lot of people, over a period of many years, and it's great to see the deal close.

Cold water coral discovery off Washington

Coral jungle discovered in the cold Pacific waters of the US northwest.

"It was really breathtaking," said researcher Mary Sue Brancato, describing "huge red sea corals atop boulders that had rockfish all over them."

Sadly, most of the sites have been damaged by fishing. Some were "festooned" with abandoned fishing gear, and others were crushed or overturned, with the telltale tracks of bottom-trawling fishing nets nearby.

Despite being in the Olympic Coast National Marine Sanctuary, most of the sites are unprotected. Recently enacted coral protection zones were placed elsewhere, where few people fish, at the behest of the fishing industry.

Starving ocean animals--links to global warming?

Fish and birds have gone missing off the US west coast, and the culprit seems to be a lack of plankton, the base of the ocean food web.

Big surprise for the US west coast, which is one of the places in the world where lush ocean life is fueled by fairly reliable "upwelling." All thanks to winds and currents that collide in the springtime and bring nutrient-rich water burbling to the surface, creating a feeding frenzy. Imagine college students flocking to free pizza and beer.

Is there a link to global warming? Plankton expert John McGowan of Scripps Institution of Oceanography said there's "a great deal of disruption going on in food webs and it's climate related."

Salty John McGowan taught my first oceanography class and he's watched plankton in the region for 50 years. If he's worried then so am I.
