Parasitic Sea Lice Threaten Salmon Farming

 By Theodora Filis

Salmon farmers around the world consider sea lice to be the most dangerous threat to their industry.



Salmon farms and their farmers are being disrupted around the world because of sea lice attaching themselves to, and feeding on, the #Salmon. This is causing many salmon to die or making them unsuitable for people to consume.



Price of salmon going up
Salmon prices are going up as much as fifty-percent - wholesale - from last year. That means as consumers we will see higher prices for salmon stakes, fillets, and the lox on our bagels.

Vice President of Cooke Aquaculture, Jake Elliott, from Blacks Harbour, New Brunswick, Canada, said that the salmon #Farmers need to be quicker and work faster than the lice.

New and established ways are being used
Both new and established technology will be needed in order to defeat the lice, experts say.

Older tools like pesticides and more recent practices like breeding for genetic resistance need to be tried. Some of the more recent solutions that are either in use now, or in the developmental stages include such things as zapping the lice with underwater lasers and trying to remove the lice by bathing the salmon in warm water.

Salmon farmers say sea lice is considered one of the biggest and most dangerous threat the industry faces - worldwide. In 2015 the Food and Agriculture Organization of the United Nations reported farmed salmon to be worth close to twelve billion U.S. dollars.

A scientist from the Canadian Department of Fisheries and Oceans, Shawn Robinson, said the only hope of controlling the infestation of these parasitic sea lice is to find new ways to control the spread. Lice are present in the wild, too, Robinson said, but they apparently live longer and stronger in tightly packed ocean pens like fish farms.

He went on to say that right now, there are just not enough tools for fish farmers to effectively deal with the sea lice.

Sea lice lay thousands of eggs
Sea lice grow to roughly the size of a pea and lay upwards of a thousand eggs in their very brief lifetime. Wild salmon growing in the Atlantic ocean have had to deal with sea lice for centuries, and fish farmers have been able to control these parasites in aquaculture environments for many years.

However, in 1994 farmers in Canada noticed they had a lice problem, said the executive director of research and environment with the Atlantic Salmon Federation, Jonathan Carr.

Carr said that by feeding salmon with a pesticide that contains the active ingredient - emamectin benzoate - they were able to control the lice infestation. But in 2009 the lice began to reappear and were no longer killed by the pesticide. Without the help of pesticides, the parasitic sea lice have been laying thousands of eggs each, around the world, for past 16 years.

Plastic Pollutes Every Waterway, Sea and Ocean In The World

By Theodora Filis


When we damage our water systems, we're not only putting marine life at risk, we're also putting human life and resources in peril.

Our planet currently has six plastic islands made of trapped garbage. The damage to sea life by these plastic death traps can only be imagined, but scientists are now investigating the long-term impacts of toxic pollutants absorbed, transported, and consumed by fish and other marine life, including the potential effects on human health. 



Plastic that now pollutes our oceans and waterways is having
a severe impact on our environment and our economy. 
Seabirds, whales, sea turtles and other marine life are eating
marine plastic pollution and dying from choking, intestinal
blockage and starvation. 

Scientists previously thought that only actual plastic floating in the ocean could harm marine animals. But, new research proves there are additional unseen dangers being created by the plastic we discard daily. Initially it was thought that larg…

Shoot First, Ask Questions Later – House Judiciary Committee Decides The Fate Of Online Piracy

By Theodora Filis

The US House Judiciary Committee is now discussing an anti-online piracy bill that will allow independent parties to cut off websites accused of posting copyrighted material. Called the Stop Online Piracy Act (SOPA), the bill is designed to get around the Digital Millennium Copyright Act (DMCA).

Committee Chair Rep. Zoe Lofgren (D-CA)
Currently, under the DMCA, a copyright holder can request a website remove material he or she owns. If the website refuses, the matter can go to court.
Under SOPA, which will go before the House Judiciary Committee on November 16, 2011:
      o Search engines can be required to block accused websites from results.

      o Internet service providers can be required to block accused websites from their customers.

      o Payment companies don't need a request from a copyright holder to block a website. Instead, they can do so on their own if they suspect a website may be posting copyrighted work without permission.


SOPA allows the third pa…

Patty Ameno's “Mad, Junkyard Dog Mentality” Is Barking Up The Right Tree and Getting Results

By Theodora Filis
Patty Ameno has been a steadfast and solitary solider, for over 25 years, in the battle to set to rights the horrific, self fulfilling acts of the Nuclear Industry. Ameno is well known for her environmental activism and for spearheading a 14-year lawsuit with Attorney Fred Baron, for wrongful death, personal injury and property damage from the operations of two former nuclear fuel plants in Armstrong County, Pennsylvania. The owners of the plants, Babcock & Wilcox and the Atlantic Richfield Co. settled with over 300 plaintiffs for more than $80 million in 2009. Ameno has received honors and recognition from the State of Pennsylvania, US Senate, and The Group Against Smog and Pollution (GASP).

Most recently, Patty was the focus of an article written by John Emshwiller, Wall Street Journal, titled: Waste Land: One Town's Atomic Legacy: A $500 Million Cleanup:
