Daily Fishing and Outdoor Report

Sat. Sept. 5, 09 -- Nicer day but fishing might not take notice

Saturday, September 05, 2009: Waves: 3- to 4-foot easterly groundswell. Water clarity: Good. Water temps: Low 70s. Winds: Light.

Looks like we can pull off a real nice Saturday. A solid week or brisk northerlies has backed off a bit. It’s calm as all get-out this early a.m. and I see a few boats already heading out for blues or bass or weaks or whatever – anything but fluke. It would be nice if the fall fishing began juts like that. poof it’s Labor Day and big bass and blues begin bustin’ out all over. No such luck, especially with this 70-dgree water seemingly entrenched, despite cooler nights. The bay is cooler so the bait will surely be readying to move. In the past ten years, the mullet have come and gone by the time the big stuff arrives on the beach and boat scene. The huge number of fluke that will be caught as bycatch will not be pretty. I can assure that enforcement has turned it up just for that reason.

We’re on the down side of the full moon so tides will be decreasing, though winds will be picked up from a relatively rare easterly direction by tomorrow, and could get testy. This will blow in very mild water. Holgate will remain a tricky drive at higher tides.

{Copyright 2009 NewsRx Science] - September 4, 2009 -
Sandbar, dusky and tiger sharks are among dozens of shark species living in the coastal waters off the U.S. East Coast.

Little is known about many of the species, but a survey begun nearly 25 years ago is helping scientists and fishery resource managers to monitor shark populations and their role in marine ecosystems.

NOAA scientists from the Northeast Fisheries Science Center (NEFSC) lab in Narragansett, R.I., recently conducted their ninth coastal shark survey from Florida to Delaware. The survey, conducted every two to three years, is the longest survey independent of the fishing industry of large coastal sharks in the U.S. Atlantic Ocean.

Using commercial Florida-style longline fishing methods to standardize results from survey to survey, researchers caught 1,675 sharks from 19 different species and tagged 1,352 individuals during the 2009 survey in April and May. Most of the animals caught and tagged were sandbar sharks, a common species in the western Atlantic. Longline fishing is a type of fishing that uses a long or main line with baited hooks spaced out at certain intervals along the line.

'During the survey, we often catch 19 or more species, many of which are highly migratory, and we still have a lot to learn about them,' said Nancy Kohler, who heads the Apex Predators Program at the Narragansett Lab and has been on every survey. 'We do not know how large certain species are when they mature, for example. It is important that we obtain basic biological information from the fish we catch so that we can learn as much as possible about their life histories, or the changes that the animals undergo from birth to death.'

Researchers record the length, sex and location of each animal caught before the fish is tagged and released. The sharks can range from 1 foot to 15 feet; they are not weighed. Any dead fish are carefully dissected at sea, with researchers looking for parasites, collecting DNA and blood samples, and obtaining samples for studies of age and growth, reproductive biology and food habits.

The first systematic survey of Atlantic sharks was conducted by the Apex Predators Program in 1986 between Florida and southern New England waters from 5 to 200 meters deep (about 16 to 660 feet). In addition to basic biological information, researchers gather data on shark abundance and distribution and migration patterns.

Kohler said the survey is conducted in the spring because coastal shark species distributions are concentrated during this time of year since the waters north of Delaware are too cold, thus making it easier to survey the whole population. Nearly all of the surveys have been conducted from the NOAA ship Delaware II, based at the NEFSC's Woods Hole Laboratory.

'We caught more fish and tagged more fish on this survey than any other,' said Lisa Natanson, who heads the coastal survey effort and has been on all but one of the surveys. 'The previous high total was in 1998, when we caught 917 sharks and tagged 859. Some years we catch very few, so it really varies.' In addition to numerous sandbar sharks, the researchers also caught one great white, many tiger and dusky sharks, and some Atlantic sharpnose. The current data are part of just one of several long-term data sets that are used to determine the health of shark populations.

The survey takes six weeks to complete and is divided into three legs, each approximately two weeks long. Eight scientists are on board for each leg, and fishing is conducted around the clock. Environmental information, such as water temperature and ocean chemistry, is obtained at each station.

Survey data are provided to the fishery managers who monitor populations in the Atlantic and Gulf of Mexico. NOAA Fisheries Service manages the commercial and recreational shark fisheries in U.S. waters, including the Caribbean Sea and the Gulf of Mexico. The United States began regulating shark fisheries in 1993 and currently manages 39 species. A fishery management plan that includes sharks, swordfish, and tunas went into effect in 1999, regulating sharks under a catch limit and quota system.

In addition to the coastal shark survey, Kohler, Natanson and colleagues in the Apex Predators Program work with thousands of volunteers throughout the Atlantic Ocean, Gulf of Mexico and the Mediterranean Sea through the Cooperative Shark Tagging Program10./. The lab also manages and coordinates the Cooperative Atlantic States Pupping and Nursery Survey, collaborating with researchers in coastal states from Rhode Island to Florida to conduct a comprehensive and standardized investigation of shark nursery areas.

Scientists in the program conduct life history studies of commercially and recreationally important shark species, participate in and conduct a variety of research cruises, and often go aboard commercial vessels to obtain biological samples from the catch as well as to tag sharks. Biological samples are also collected from recreational fishing tournaments in the Northeast U.S

[Asia Pulse] - September 4, 2009 - SYDNEY, Two Taiwanese longline tuna fishing vessels were yesterday caught by Greenpeace in the act of illegally transferring fish in Pacific waters.

Fishing vessels Her Hae and Jia Yu Fa were carrying tuna and shark fins, and were photographed while transferring tuna from one ship to another in a pocket of international waters between Papua New Guinea and the Federated States of Micronesia, an area proposed as a marine reserve. They abandoned their transshipment process and fled the area as the Greenpeace ship Esperanza approached the vicinity.

The Esperanza, campaigning to end the destruction of the world's oceans, peacefully escorted the vessel Jia Yu Fa out of international waters and into the waters of the Federated States of Micronesia where it has a license to fish. Greenpeace has reported the Taiwanese vessels' illegal transshipment at sea to relevant authorities.

Pockets of international waters in the Pacific, which are regulated by the Western and Central Pacific Fisheries Commission (WCPFC), are known to be especially vulnerable to pirate fishing as previous Greenpeace expeditions in the region have demonstrated. The WCPFC has agreed to close two of the pockets to purse seining from January 2010 but the areas will remain vulnerable to overfishing by longline fleets.

Members of the WCPFC must now shut down all pockets of international waters to all fishing including longlining and ban the transshipment of fish at sea, which currently gives pirate tuna fleets the opportunity to keep plundering the Pacific Ocean, said Josua Turaganivalu, Oceans Campaigner of Greenpeace Australia Pacific on board the Esperanza.

Longliners like Her Hae and Jia Yu Fa are part of a vast Taiwanese fleet of such vessels and mainly target bigeye and yellowfin tuna, destined for luxury sashimi markets. Many also fish exclusively in international waters where little regulation exists. Scientists have warned that both species are already seriously overfished and fishing must be drastically reduced . In addition, approximately 35 per cent of longline catch consists of non-target species, including threatened oceanic sharks and turtles. Many tuna longline vessels also engage in controversial shark-finning activities.

Pirate fishing by longline fleets is also thought to be significant, and often facilitated by the transfer of fish at sea (4). A recent report estimated pirate fishing in the Pacific makes up an average of 36 per cent of the entire fish catch, which is much higher than the global average of 19 per cent.

The Esperanza's 'Defending Our Pacific' tour is part of an international campaign for clean and healthy oceans through the creation of a global network of marine reserves and effective enforcement of laws that protect ocean life. Greenpeace is monitoring the pockets of international waters that Pacific Island Countries want closed from all fishing activities in order to protect the declining tuna stocks. The WCPFC has already agreed to close two of the areas to tuna purse seining from January 2010 onwards, but the areas are still vulnerable to overfishing.

Time and tuna are running out. The WCPFC can become a global leader in oceans conservation by agreeing to immediately reduce fishing by half and by closing all four pockets of international waters in the Pacific at its summit in December,' said Karli Thomas, Greenpeace New Zealand oceans campaigner, on board the Esperanza.
