Forage Fish Should Stay in the Ocean

Yesterday a task force of thirteen distinguished scientists from around the globe released a new report, “little fish BIG IMPACT” that investigates the science of ocean food webs, the critical role of forage species, and the urgent need for changing fishery management approaches.  In the most comprehensive global analysis of forage fish science and management to date, the Lenfest Forage Fish Task Force details how current management is too risky and how it fails to account for the critical role of forage fish as food for marine mammals, seabirds, and commercially important species such as salmon, tuna, cod and rockfish.  This report validates what Oceana has been pushing for in the fishery management arena for years, and provides conclusive scientific justification for major overhauls in how we manage fisheries for forage fish.

This is part of a series of posts about our Pacific Hotspots expedition. Today's highlights: On their final day in Oregon, the crew ventures into uncharted territory and finds a variety of corals and fish.

Oregon Leg, Day 5

Friday was our last day aboard the R/V Miss Linda and it could not have been a better day for working on the ocean. We left the Charleston Marina at 7 AM bound for the nearshore reef south of Cape Arago and west of Seven Devils State Park. 

As we were working in and out of Charleston today, we invited guests to join our expedition including Dr. Craig Young, the director of the University of Oregon’s Oregon Institute of Marine Biology and Dr. Jan Hodder from the Oregon Institute of Marine Biology.

The University of Oregon has been operating marine studies in the Charleston area since 1924 with year-round research programs beginning in 1966. Dr. Young and his graduate students have made hundreds of deep dives in submersibles and sailed on oceanographic ships in the Atlantic, Pacific and Indian Oceans. Yet surprisingly, nobody has ever been to the areas we went Friday with a Remotely Operated Vehicle (ROV) and underwater camera.

Exploring Oregon's Coquille Bank

This is part of a series of posts about our Pacific Hotspots expedition. Today's highlight: prehistoric hagfish.

Oregon Leg, Day 4

Today we ran the R/V Miss Linda twenty miles west of Bandon, Oregon to Coquille Bank. This offshore bank, also known as the Bandon High Spot, rises up off the continental shelf break to a relatively shallow 300 feet in depth. Oceana worked to protect this area from bottom trawling in 2005. The regulations went into place in 2006 and now five years after the area was protected, we had the chance to dive there with the ROV. 

In 2007, Drs. Mark Hixon and Brian Tissot published a scientific paper on the effects of bottom trawling at Coquille Bank. They found striking differences in the seafloor communities between heavily trawled and untrawled areas including more fish abundance and more diversity in the untrawled areas. They also found that bottom trawling affects marine life living in soft sediments and not just rocky seafloor habitats.

Coral Gardens Near Bandon, Oregon

 Oregon Leg, Day 3

Last night we anchored the R/V Miss Linda just north of Bandon, Oregon and two miles offshore. We woke to calm seas and high anticipation for another day of work with the Remotely Operated Vehicle (ROV), surveying seafloor habitats. 

Steaming west about six miles offshore we crossed paths with a rapidly moving pod of dolphins and we were graced with the company of black-footed albatross and sooty shearwaters.

As the ROV descended on the first dive, we passed through a swarm of krill just before reaching the seafloor 300 feet down. At the bottom we saw a garden of colorful corals, sponges and crinoids that looked like sword ferns in an old growth forest.
