Wild salmon deaths linked to sea lice at fish farms

Wild coho and pink salmon die when young fish migrate through areas where there are sea lice outbreaks on fish farms, a new study concludes.

The paper, whose lead author is Martin Krkosek, a researcher at the University of Otago, Dunedin, New Zealand, was published Monday in the Proceedings of the National Academy of Sciences and the findings directly contradict a previous study that concluded there was no link.

"Our results show that sea lice abundance on farms is negatively associated with productivity of both pink and coho salmon in the Broughton Archipelago," it says.

"When lice numbers on farms are high, the numbers of wild stocks decline," Krkosek said in an interview.

Oil-slicked pelicans found near TC port

Two oil-slicked pelicans are recovering at a wildlife rehabilitation center in Seabrook after being found Monday near where 50 barrels of bunker oil spilled into the Texas City ship channel during the weekend, officials confirmed.

It was unconfirmed if the birds were covered in oil from the spill at Dock 34 at the Port of Texas City or the oil source was from elsewhere.

Officials with the Unified Command initially said there were no impacts on wildlife from the spill.

It was Texas City officials who revealed the information to The Daily News after finding out.

One of the birds had a wing missing, an injury that is not believed to be related to the slick that forced the closure of the Port of Texas City and Texas City Dike on Friday and Saturday, Unified Command spokesman Henry de La Garza said. The bird also was malnourished.

A second bird did not have any injuries, but also was covered in oil.

Both birds were being cared for at Wildlife Response Services in Seabrook.
