HOW MUCH DAMAGE HAS HUMAN FISHING DONE TO THE OCEAN?

HOW MUCH DAMAGE HAS HUMAN FISHING DONE TO THE OCEAN?

We thought we could fish forever, because the sea was a limitless protein mine. But dawning now is a realization that we were wrong about that. But how naive were we? And what price will be paid? Ocean life is dying back in unexpected ways: although there are fewer fish and other sea animals, more of them are starving, while waves of 'sickness' spread as primitive microbes gain the upper hand. Symptoms include spreading 'dead zones,' harmful algae blooms and a diminished presence of sea animal life in general. Is fishing implicated in all of this?

Atlantic Canada reveals what is probably the clearest evidence anywhere of the ecosystem-effects of persistent human fishing. The early 1990's crash of the once great Canadian cod stock is held up as a global cautionary tale against fisheries mismanagement, against greedy human 'overfishing.' But less well known is that the story is not that simple, that, at the level of scientific detail, so much has gone severely and unexpectedly wrong in Atlantic Canada...that the most basic assumptions underlying the 'science of overfishing/sustainable fishing' must now be questioned.

Zooplankton were unexpectedly and inexplicably lost along with Canadian fish stocks. If, as seems likely, this is part of the ecosystem impact of fishing, then this finding has global significance.

Evidence: a Transformed Ecosystem

As the size and abundance of commercially targeted fish species has plunged in recent decades, populations of smaller, unexploited organisms, the 'foundation' species of the marine ecosystem, have also experienced major downshifts. Oceanic zooplankton is in decline, and NASA/NOAA has recently reported an apparent global declining trend in marine phytoplankton production. Evidence suggesting lowered marine nutrient cycling can also be seen along clean oceanic shorelines.

Example: A clean, rocky intertidal zone in Atlantic Canada was heavily dominated by barnacles (filter feeding animals) in summer, 1948, reflecting relatively high marine productivity at that time. (Photo from Stephenson and Stephenson 1954 J. Ecol. 42:14-70 ) Move mouse over photo to see this site in summer, 2002. Now dominated by rockweed with relatively sparse barnacle cover, with individual barnacles very small, this shift away from dominance by filter feeders, and towards dominance by seaweeds, offers classic evidence of a decline in "nitrogen loading" rates. (Carpenter and Capone, Nitrogen in the Marine Environment (Acad. Press, NY, 1983)) This pattern of shifting dominance from filter feeders to seaweed is also widely evident today in the tropics where mass coral bleaching and infectious coral epidemics signal the failing health of those once dominant filter feeders.

Diving With Sharks

My first experience with sharks came at the age of six, looking through the glass of a San Diego Aquarium, looking bright eyed and up at these big fish with fangs and ugly teeth. Kind of like what my daughter looks like when she wakes up in the morning.

When I was little and every chance to visit this sharks I took the chance, not many visits but the few I was able to do, until I got older, I knew then what I knew now. I fell in love with these beats. They are magnificent creatures of mystery and intrigue.

You want the best; dive with these guys:

NO Body BETTER!

Discover cage diving with great white sharks off Australia, California, and South Africa, or try scuba diving with the Caribbean reef sharks of the Bahamas, encounter whale sharks, or hammerheads. This section features some of the top shark diving destinations around the world, and where to go for the best shark diving opportunities

Learn why sharks are some of the most interesting and mysterious creatures in the sea. Have you ever wondered where would be the best place to go cage diving with great white sharks? Or what kind of shark is the biggest fish in the sea? Here are a few quick facts about some of the species most commonly encountered by divers.

For over 400 million years sharks have been the oceans top predators, dominating the marine world and swimming without fear. But now over-fishing and a rising demand for shark body parts, such as cartilage, teeth, and especially the fins, have placed many of the worlds sharks in danger. Check this section to learn more.

Diving With Sharks is here to make your next shark diving experience as seamless as possible. We have selected the top vessels out of San Diego, checked the dive crews and reviewed everything down to your meal service and cage construction. In short these vessels are the best you can get.Shark diving allows shark enthusiasts, divers and non-divers an easy way to observe the extraordinary world of Great White Sharks.

The shark cages we use create a discernable barrier that our sharks quickly recognize allowing us to safely observe and experience these incredible animals up close and personal. Safety is our highest priority, for both divers and our sharks. Shark diving is unique in the fact that the rewards often far exceed the effort both physically and mentally. Not to say that shark diving is not challenging, getting in the water with up to five Great Whites can very challenging and very exciting to say the least!

Shark diving with us requires less equipment to bring along, and only minimal equipment is needed to dive in our cages. For instance we use surface supplied air at Isla Guadalupe, thus no tank is required to be worn in the cage or while climbing in and out of the water leaving more room in the cage. We also provide regulators and weights. Our shark diving crews are industry professionals who care about your safety and enjoyment. In the world of cage diving with Great Whites you can either go where everyone has been before, or discover a newer and better world.

It will change the way you think of adventure forever. Period!
