Offshore Osa Drilling Again in 2012

clock November 9, 2012 13:36 by author BlueEcoBlog

Marine life behavior alters after drilling

From The Tico Times Posted: Friday, June 17, 2011 - By Shawn Larkin
THE BIG BLUE: Dolphins have scattered and no whales have been seen in the area since a foreign research vessel drilled into the ocean floor earlier this year.
Rash of Rashes: A dolphin off southwestern Costa Rica’s Osa Peninsula displays a skin rash.

The blue-water pelagic ecosystem offshore of southwestern Costa Rica’s Isla del Caño Biological Reserve and Corcovado National Park took serious one-two punches during the past few months, and it remains to be seen whether things will ever return to conditions of the past. The area around, not inside, the two protected areas is probably Costa Rica’s most critical dolphin and whale breeding and feeding waters. But the whales are gone, and the dolphins have changed. The fishing has been off, and boats are headed elsewhere to find fish.

The first few months of the year shaped up to be one of the best seasons for marine life in Costa Rican waters in recent memory. The cool currents of La Niña stoked a profusion of big pelagic species like dolphins, whales, tuna, turtles and giant mantas. Divers and snorkelers from the Southern Zone reported more giant mantas seen at Caño Island in February and March than in the past 15 years put together. Flights and boats searching for marine life in the area were finding dolphin superpods, groups of dolphins numbering in the hundreds to thousands, all over the area. There were many mating and birthing humpback whales, a large pod of false killer whales, orcas, fin whales and even three blue whales, including a baby, feeding on giant bait balls of small fish brought up from the depths during the normal strong upwelling at this time of year. There were uncountable hectares of turtles, tuna and billfish. There were even a few big sharks.

Then, a giant foreign ship showed up and began drilling deep holes in the ocean floor not far from Caño Island, in the name of scientific research. Within a day, the whales were gone. Search time for dolphins from a plane went from a half hour or less to two hours or more. Most dolphin superpods broke into smaller groups and headed north toward offshore Quepos. Others broke into smaller groups and moved inshore, closer to the coast. Dolphins that stayed in the area developed a strange skin rash.

The spewing ship kept at it for a month. Great areas of waters turned from marine blue to metallic brown and green. The day after the ship left, a new one showed up towing many kilometers of giant air guns blasting extremely loud sounds repetitively. A week later they were still at it. Drake Bay ecotourism and sportfishing boats foolish enough to still be looking in their favorite hot spots were told to leave the area by burly men on a yacht out of Quepos. Scuba divers at Caño Island could hear the giant booms of the guns during their dives.

No environmental impact study was done for the area. No dolphin and whale observers were onboard to look out for cetacean safety. There were no Costa Ricans onboard until someone noticed. Many questions were never answered. No notice was given to area residents of what was going to happen.

Since the drilling, no whales have been reported in the area – the longest period without whale sightings that anglers and guides in Drake Bay can remember. No large dolphin superpods have been seen. The fishing is bad. No wonder so few tourists seem to want to visit the area right now.

This serious lack of ocean oversight has left locals wondering what is next. There are reports of making a permanent drilling riser here and of laying an undersea cable from the mainland to Caño Island and then offshore to the rig.

Let’s hope an environmental impact study is involved and that locals dependent on the area’s marine life are given some notice so they can find new jobs. Because what’s next could be the knockout punch for a good chunk of Costa Rica’s famous marine life: whales, dolphins, turtles – and fishers and divers.

Are tourists keeping Costa Rican dolphins awake?

clock August 30, 2012 09:28 by author BlueEcoBlog

Are tourists keeping Costa Rican dolphins awake?

Dolphins need protected areas and times.

Recent research on Hawaiian spinner dolphins indicates that they need protected times and places. Surprise! One bay is visited by as many as sixty swimmers at a time who try to play with a small group of dolphins. Seems the dolphins rest in the early daylight hours, and that’s when many swimmer tourists head out. Less dolphins may come into the bay and the dolphins might leave earlier than usual when too many people show up. Spinners in Hawaii rest in small groups near shore in shallow sandy bays near deep water. Scientists say these places need protection. Clearly tourists should be told to leave the dolphins alone in the early daylight hours and fishing and extraction should be stopped in the bays. Costa Rican dolphins should have it so good.


Costa Rican spinner dolphins deal with giant nets towed by ships, helicopters dropping bombs, long lines full of hooks, shrimp trawlers bulldozing the bottom, surprise drill ships making a big mess, big banging seismic surveys, cargo ships blitzing by, sport fishers plowing through the pod with lines and hooks, tourist boats gawking, and even some divers in the water. How do you think that effects their beauty sleep?


Don't forget here in Costa Rica spinner dolphins have no protected place at all.


Costa Rican spinner and spotted dolphins, who also rest in the early daylight, need tourists to leave them alone at this time. Sport fishing boats need to stop fishing in the dolphins as they particularly like the early hours of the day. Many hotel managers want tours to leave early to get everyone out of the hotel, but this is the wrong strategy if you are concerned about dolphins. Tourist operators like divers and fishers should put up on their web pages that they leave the dolphins alone in the am. Guests of Costa Cetacea over the years will recall that all tours leave late and respect the dolphins rest time, much to the frustration of some hotel managers. The interactions here in Costa Rica are much more interesting in the PM anyway.


Aloha to the Hawaiians for once again being the world ocean leaders. Lets hope Costa Rica follows.

Pelagic Park’ Would Help Save Spinner Dolphins

‘Pelagic Park’ Would Help Save Spinner Dolphins

From The Tico Times, Posted: Friday, September 05, 2008 - By Shawn Larkin

The most hightech, large-scale fishing in Costa Rica’s oceans is commercial tuna fishing.

From hardworking crew and helicopters to radar and satellites, these operations take catching fish very seriously.

They drop enormous nets bigger than a city block into the sea to catch vast quantities of an assortment of marine life. They are after mostly tuna, among the most valuable fish of any denizens of the deep.

When fishing boats find a big group of spinner dolphins, they find some of their ever-present sidekicks: giant yellowfin and bigeye tuna. Mostly seen only below the surface, the tuna would not be so easy to locate without the help of the dolphins, which must surface regularly to breathe. The giant tuna pack together around the dolphins that find their food for them. Here, offshore of southern Costa Rica’s Osa Peninsula, the big tuna and the spinner dolphins are always together.

I reckon the dolphins think: “Now that the  moon is full, the current is from the southwest at two knots and the wind is calm, a bigspaced swell is coming in from west-southwest, it rained last night and the layers of water temperatures changed a lot, it’s a sunny day, almost high noon, and I think I know where all those other dolphins are going, and the orcas will not hunt today, and the tuna boats will be busy for a few hours – hope my friends and family make it out! – we should go hunt the south end of the Osa drop-off upwelling.”

And I reckon the tuna are thinking just one thing: “Follow the dolphins.”

Follow the dolphins. Just as the seabirds, the sailfish and the marlin, the sharks and the whales, the sportfishing captains and the commercial tuna-fishing fleets do. Follow the dolphins; they have the best actionable ocean intelligence. The dolphins have the network. They are always with the food.

In the Osa drop-off upwelling, where dense, cooler and nutrient-rich water is pushed toward the ocean surface, the tuna, birds and other marine life are nearly always with the dolphins. All a commercial fishing fleet has to do is find the birds on a special radar, send up a helicopter or two to check it out and call in coordinates, start corralling the dolphins with the helicopter and explosives dropped from the helicopter, put down small, fast chase boats to further corral the dolphins, use the ship to corral the dolphins even more, and then put down a very big net around the dolphins and associated marine life with the help of a special net boat.

If you do this, you get a lot of tuna in the net below the dolphins, and it’s worth a lot of money.

Sadly, this kind of bonanza is unsustainable. The longer-lived, more slowly reproducing spinners will probably die out before the tuna are exhausted, perhaps giving the tuna a chance to recuperate, because once the dolphins are gone, no one will be able to find the tuna. But how will the tuna find food without the dolphins?

Fishing industry insiders have told me that dozens of spinner dolphins are killed every day by busy boats. They die most frequently when their narrow, smiling mouths get stuck in the holes of the nets. Hundreds more must be manhandled by diving crews and thrown out of the nets daily, lest the nets are damaged.

Other Osa dolphin species, such as bottlenose and spotted dolphins, are somewhat likelier to swim out if a small piece of one end of the net is put down for a while, a procedure known as a “backdown.”

Backdowns do not help Osa’s spinner dolphins, however; they stay in the net.

Tuna fishermen say the spinners are tontos, stupid, because they do not swim away from the ship and out of the net. They seem unable to stop surfing the ship’s waves. The same trait the tourist boats love dooms the poor spinners.

Time for ‘Pelagic Park’

The blue-water pelagic (open-ocean) ecosystem domain of the Osa’s spinner dolphins is probably the most productive ecosystem in Costa Rica, perhaps in the tropical marine world. According to former members of Jacques Cousteau’s legendary conservation ship, Calypso, and the BBC’s top “Blue Planet” underwater cameramen, offshore Osa is the richest tropical blue water they have seen anywhere on the planet (see sidebar).

The dolphins’ domain is an area between five and 20 nautical miles from Caño Island Biological Reserve. The reserve’s waters currently extend only about two nautical miles; this is not enough to protect large animals such as dolphins and tuna. To protect large marine animals, you need a Corcovado or Amistad-sized park at sea.

For many years, around the world, protected marine areas have proven to increase catches in surrounding areas. With a big enough pelagic park, or better still, parks and corridors, tuna-fishing boats could make money in the long term, not just short.

An astounding number of big, amazing  animals live in the Osa drop-off upwelling area and would be protected along with the spinners. Fin, sei, Bryde’s, humpback and blue whales and orcas frequent this little upwelling. Sailfish, marlin, tuna, manta rays, whale sharks, turtles, beaked whales, pilot whales, pseudorcas, bottlenose dolphins and spotted dolphins are found here in some of the highest concentrations in the world.

A special area of the Osa drop-off upwelling, the clearest waters in Costa Rica, would be an excellent place to prohibit commercial fishing, save the spinners and allow boaters and divers to see and snorkel with dolphins and other amazing marine life in the big blue.

Many people in Costa Rica, including yours truly, already benefit greatly from tourists visiting the giant dolphin pods and other marine life congregations off the Osa. But the commercial fishing fleet will end it soon for us all if some sort of pelagic park is not created.

The spinners are dying. There seem to be a lot fewer little spinners now then there were in the past. The pods no longer stretch to the horizon in every direction.

A park is the only solution. Just as Costa Rica has demonstrated to the world the value of protecting functioning terrestrial ecosystems, we can show the world the same goes for the ocean. Costa Rica needs to make peace with the ocean as well as the rain forest. It’s time to set aside a meaningful, not miniscule, part of Costa Rica’s biggest ecosystem: the open ocean.

Tuna Fishing Endangers Dolphins in Costa Rica

clock August 7, 2012 12:25 by author BlueEcoBlog

Dolphins are Costa Rica’s most famous divers – and they have a problem. For decades, in the eastern tropical Pacific, the commercial fishing industry has hunted dolphin species that form enormous congregations, such as pantropical spotted, spinner, bottlenose, common and Risso’s dolphins.

Tuna always school beneath large groups of dolphins, so corralling the dolphins with helicopters and speedboats causes the tuna to form a more easily netted mass below. Unlike most sport fishers who catch a few fish in a sustainable way, many commercial operations set vast nets around dolphins in hopes of grabbing all the tuna possible. This technique has killed millions of dolphins, and continues to kill them as recently as last month off the Southern Zone’s Osa Peninsula.

Dolphin and tuna are often about the same size, and eat the same size of prey. The vast groups of yellowfin tuna constantly following large dolphin groups are led to lunch. The tuna seem to instinctively follow the dolphins, as do birds and other fish, because dolphins will find the food. The big brains of these marine mammals figure to look for chow a few miles offshore of an island, when the tide is high, the moon is full, the wind is clam, the water temperature is just right and the coast is clear, and the needlefish are schooling. The tiny brain of the tuna might just think: follow the dolphin.

Dolphins, being so social and traveling in such large groups, actually create a sort of structure, like a reef, in which smaller fish can hide as well as collect scrapes. Many species of fish, besides tuna, cruise in groups with the dolphins, including silky sharks, blue marlin and sailfish.

We call this famous phenomenon the tuna-dolphin association of the eastern tropical Pacific, not because it’s just tuna and dolphins but because huge commercial fishing fleets use dolphins breathing at the surface to find the tuna swimming below them. Many different species die in the nets of commercial fishing fleets. You may have heard of “dolphin-safe tuna”; this catchy phrase is better described as “some dead dolphin and mixed-species tuna.” The aforementioned catching method, sometimes still used, is “major dead dolphin and mixed species tuna.” As far as I know, none of the forms of massive-scale tuna fishing is even remotely safe for dolphins – some ways just kill less than others do.So, how do the methods differ? One is called a “backdown.” After netting all the tuna and dolphins through the normal process, the ship motors slowly in reverse. This, with the help of a few speedboats, lowers a part of the net down below the surface. Hopefully, the freaked-out dolphins will then swim out. Sometimes they do. Sometimes boats chase them out. But if the tuna follow them, the net is quickly yanked up. All the while, daylight is fading, the crew and workers are on the clock, and fuel is being guzzled. This is “dolphin-safe” tuna. Other methods don’t even use a backdown.

Waiting to catch the tuna when they are away from dolphins requires more time, effort and money, but is the only way to ensure dolphins are safe from slaughter. Reportedly, some boats do not set on dolphins, but until tuna consumers make this distinction, the prices of unscrupulous competitors will hurt the real “dolphin-safe” businesses.

Dolphin tourism can sometimes be at odds with commercial fishing interests. It makes it a little harder to surround a group of dolphins with helicopters, speedboats and a factory ship when a happy group of photosnapping tourists is in the way. On rare occasions, frustrated pilots in rickety helicopters that look more like lawn mowers than aircraft will attempt to drive off the people by buzzing a tourist boat near dolphins. If you are rooting for the dolphins, you can stay with them until there is not enough daylight for the time-consuming process of chasing and netting.

Why don’t the dolphins just smack a few boat captains on the head as they jump over the nets and swim away giggling? Because, like humans, dolphins, once they start to panic, are not so smart. Ancient instincts, such as freaking out, take over. And, as with humans, being in large groups makes panic worse. Dolphins are used to vast spaces; a net causes panic, and they just don’t think to jump over.

I wonder how commercial fishers will fare once the big pods are gone. This may sound distressingly familiar if you know about the vast herds or flocks of animals, such as American bison and passenger pigeons, which have disappeared on land and in the air. As the buffalo once did, the dead dolphins rot in waste or fall to scavengers, and, as with the passenger pigeons, a point may arrive when the population crashes suddenly to extinction.

Dolphins-Should we swim and sing with them or put hooks and nets in with them?

clock July 20, 2012 14:00 by author BlueEcoBlog

Dolphins from this pod still being killed in July 2012.
Should Costa Rica kill them for tuna?
The video in the link below is Shawn Larkin freediving and singing with the spinner dolphin superpod of Osa, Costa Rica. Some people net dolphins, some people put lines and hooks in the water with dolphins. Some people sing and swim with them. What do you think is the right answer?

Why does KETO Costa Rica and Mar Viva and PROMAR,do nothing to help these spinner dolphins? They will take your money though and praise themselves for dolphin conservation, but what about our largest dolphin pod?.


Why do so many Costa Ricans cry about Faeroe Island and Japan and Greenland Cetacean kills, yet do NOTHING YEAR AFTER YEAR, to help their own resident spinner dolphin superpod from being killed in net and lines?

Why have so called Costa Rican dolphin conservation organizations not said one word about our Osa spinner dolphin superpod, the biggest resident dolphin superpod IN THE WORLD!
why?

$$$$ and corruption
Thats why.

Sharks are getting a lot harder to fish in Costa Rica, as the thieves have hardly left any.
The money now is in tuna that swim with dolphins, and its a lot more profit if you Ticos keep looking the other way por favor.

At least the other countries try to defend their sick atrocities. We Costa Ricans try to hide ours by whining and directing attention to others.

Pelagic Parks For Everyone!
