Sci-News.com Four New Species of Deep-Sea Anglerfish Found in New Zealand Waters Sci-News.com Marine biologists from Taiwan and New Zealand have identified four new species of deep-sea fish in the anglerfish genus Chaunax.
In a 2003 study, fish were injected in the lips with bee venom or an acid solution.
The fish reacted immediately, rubbing their lips on the side or bottom of their tank, rocking from side to side and breathing at a rate comparable to that of a fish swimming at top speed,New Scientist reports.
And a 2009 study found that after experiencing a painful event, fish demonstrated defensive or avoidance behaviors, indicating the fish felt pain and remembered it.
"Yes, we’re going to have to learn to live with the lionfish. We’re going to have to accept their presence in the Atlantic, Caribbean, and Gulf of Mexico, but we can use science to arm us against this invasion. In the quiet lab in North Carolina, Morris isn’t just studying fish. He’s preparing us for battle. In this endless war with a formidable foe, knowledge truly is power. The power to predict. The power to pre-empt. The power to fight back and save the species we value most. The power to educate and rally reinforcements to drive back invaders. The more we know about the lionfish, the better our strategies will be to deal with them and future invaders and the better our chances of success. The lionfish caught us by surprise, but Morris isn’t going to let them stay one step ahead. Even if we can’t eradicate these gluttonous fish, we may be able to manage them and minimize the damage they do to our precious marine ecosystems.
Considering it’s our fault that lionfish are here in the first place, it’s really a war against ourselves: against our bad habits, against our casual disregard for the ecosystems that protect and sustain us, against the attitudes and mindsets that led to such a devastating invasion to begin with. It’s a war that, as a nation, as a species, we cannot afford to lose.
Big fish in many species can reproduce much more efficiently than their younger, smaller counterparts, and lionfish are known to travel considerable distances and move to various depths. This raises significant new concerns in the effort to control this invasive species that is devastating native fish populations on the Atlantic Coast and in the Caribbean Sea.

Marian Locksley's insight:
Four days later, the mycelium has grown through the substrate into the shape of the mold, producing a material almost indistinguishable from styrofoam in form, function and cost. An application of heat kills the mycelium and stops the growth. When broken up and thrown into a compost pile, the packing material biodegrades in about a month.
The fish were reportedly asphyxiated after a cattle food plant poured hundreds of liters of molasses into the canal that feeds the Hurtado reservoir, Emeterio Corona, the mayor of the nearby town Acatlan de Juarez, told Agence France-Presse (AFP).

As this video illustrates, subsidies are fuelling overfishing in European seas.
This has to stop!
You can help by letting your MEP know that you want your money to protect the future of our fisheries, not to pay for overfishing.
The gulls attack during the whales’ calving season, when mother whales arrive in the waters off Argentina’s coast with youngsters in tow. Lacking the lung capacity that allows adults to stay submerged for long periods of time, calves are forced to come to the surface for air more often, making them prime targets for patient kelp gulls, who take a few pecks from the hide of emerging whales every time they come to the surface. Those pecks add up to painful wounds, but the physical damage may be the least of the whales’ issues. The main problem, according to some researchers, is that these attacks disrupt the calves’ feeding routines, making it harder to get a full meal of whale milk from their mothers. According to researcher Mariano Sironi:
“The lack of nursing causes serious nutrition problems for the calves. Post-mortem studies have shown evidence of malnutrition, and this is a working hypothesis that needs to be confirmed with several studies.”

Bullish expansion in China’s third-largest seafood producing region means more overseas fishing and an expansion of local brands for the domestic market.
Marian Locksley's insight:
27 June, 2013 - Bullish expansion in China’s third-largest seafood producing region means more overseas fishing and an expansion of local brands for the domestic market. That’s the vision of the government in Fujian province, which recently brought together the region’s universities, maritime authorities and seafood industry representatives in a bid to establish “10 seafood superbrands from Fujian.”
Pledging grants and the support of the local (largely state-controlled) media, the Communist Party officials encouraged companies to cooperate in creating brands that can compete in a growing domestic market.
China has put much emphasis in recent years on increasing trade with Africa and Latin America, largely by government-to-government agreements and with the help of preferential loans to developing countries in return for access to local markets. Likewise fisheries here have turned to overseas waters for fish to feed growing domestic demand. Fujian has 24 companies operating 277 vessels on the high seas and has 209 vessels currently under construction.
