Where’s the kelp? Warm ocean takes toll on undersea forests

August 22, 2017 — APPLEDORE ISLAND, Maine — When diving in the Gulf of Maine a few years back, Jennifer Dijkstra expected to be swimming through a flowing kelp forest that had long served as a nursery and food for juvenile fish and lobster.

But Dijkstra, a University of New Hampshire marine biologist, saw only a patchy seafloor before her. The sugar kelp had declined dramatically and been replaced by invasive, shrub-like seaweed that looked like a giant shag rug.

“I remember going to some dive sites and honestly being shocked at how few kelp blades we saw,” she said.

The Gulf of Maine, stretching from Cape Cod to Nova Scotia, is the latest in a growing list of global hotspots losing their kelp, including hundreds of miles in the Mediterranean Sea, off southern Japan and Australia, and parts of the California coast.

Among the world’s most diverse marine ecosystems, kelp forests are found on all continental coastlines except for Antarctica and provide critical food and shelter to myriad fish and other creatures. Kelp also is critical to coastal economies, providing billions of dollars in tourism and fishing.

The likely culprit for the loss of kelp, according to several scientific studies, is warming oceans from climate change, coupled with the arrival of invasive species. In Maine, the invaders are other seaweeds. In Australia, the Mediterranean and Japan, tropical fish are feasting on the kelp.

NORTH CAROLINA: 40,000 oysters ‘planted’ in Great Bay

October 11th, 2016 — Your thoughts about oysters may not extend beyond the dinner table, but it turns out the little critters are pretty important to the ecosystem.

Realizing that the local oyster population was greatly depleted, the University of New Hampshire and The Nature Conservatory launched a program in 2009 to bring them back by nurturing millions of microscopic larvae each year and “planting” the surviving young oysters in Great Bay.

Friday was the culmination of the eighth season, when some 40,000 new oysters were heaved into the bay near Nanny’s Island by a group of about 30 volunteers and conservation workers, both adults and children.

“To the oysters!” said Molly Bolster, over an apple cider toast. “May they flourish and spend a lot of time down there,” said Bolster, who is executive director of the Portsmouth-based Gundalow Company, which provided the boat.

Oysters help filter the water, reducing pollution. However, due to diseases, excess silt, climate change and past over-harvesting, the population has greatly declined over the last few decades, said Ray Grizzle, research professor of biological sciences at UNH. Many oysters were not living long enough to produce offspring.

So how does one go about “planting” an oyster?

Millions of larvae each year are sent to the UNH Jackson Estuarine Lab, where the microscopic oysters are reared using shells collected and donated from restaurants around the state. The vast majority of larvae die before reaching adulthood, but those that survive are placed back in the bay after they have matured for several months.

University of New Hampshire researcher trying to develop sustainable fish farm

September 27, 2016 — MADBURY, NH — A researcher at the University of New Hampshire hopes to increase local food production through an integrated land-based aquaculture and hydroponic plant production system.

Todd Guerdat, an assistant professor of agricultural engineering, is leading a series of studies at Kingman Research Farm in Madbury.

He and others are taking waste nutrients from fish and using them for plants.

In three greenhouses, they are trying to determine if higher protein diets are more beneficial for plant production.

“The goal is to use all the nutrients from the feed, without having to supplement anything,” Guerdat said.

Researchers are using tilapia because they are efficient, cheap and reliable, but researchers hope is to start using cold water fish such as striped bass.

Guerdat said that if they are successful, more seafood can be raised on the local level.

According to Guerdat, more than half of the world’s seafood is farmed and 90 percent of the seafood Americans eat is imported, resulting in an annual trade deficit of nearly $11 billion.

“We are food insecure when it comes to seafood,” Guerdat said. He said there are companies that are already implementing similar systems, including Victory Aquaponics in Londonderry.

UNH research on horseshoe crabs reveals connection between water, spawning

June 24, 2016 — DURHAM, N.H. — It appears that horseshoe crab spawning is based more on water temperature than lunar cycles, according to new research from the University of New Hampshire.

Researchers found that Atlantic horseshoe crabs in New Hampshire’s Great Bay Estuary time their annual spawning based on water temperature.

It was thought that the lunar cycle triggered spawning.

The study provides a first-of-its-kind look at the environmental factors that influence horseshoe crab spawning activity in the state and could pave the way for changes in how monitoring surveys are conducted on the East Coast.

“We wanted to establish a baseline for horseshoe crab populations in New Hampshire because it had never been done before,” said Helen Cheng, who led the research. “Knowing how a species behaves is important in managing their populations, so we needed to know more about horseshoe crab spawning behaviors for effective management.”

A decline in the horseshoe crab population could affect several fields.

In medicine, horseshoe crabs play an important role in eye research and surgical sutures and a component of their bright-blue blood is used in the pharmaceutical industry.

American eel and conch fisheries use them for bait, and several other species in the ecological food chain depend on them for survival.

Northeast Consortium and NEFMC Announce Funding for New Collaborative Research Projects

NEWBURYPORT, Mass. — July 8, 2015 — The following was released by the New England Fishery Management Council:

The Northeast Consortium, a University of New Hampshire-based institution established in 1999 to foster collaborative research, under contract to the New England Fishery Management Council, announces funding for three new research projects that will focus on spawning groundfish in waters off the New England coast.

Awards totaling over $335,000 will support a mapping study examining the distribution of spawning cod on Georges Bank, an acoustic and trawl survey of winter-spawning cod in Ipswich Bay, an inshore area off the coast of MA, and work on winter flounder spawning activities offshore in the Gulf of Maine.

The result of a supplemental request for proposals issued last February, projects were required to articulate collaborations between commercial fishermen and scientists, and could include, among other approaches, research that enables the Council to improve groundfish spawning protection by increasing the understanding of groundfish spawning activity or aggregations of spawning groundfish.

Here are more project details.

Project Title: Mapping the distribution of Atlantic cod spawning on Georges Bank using fishermen’s ecological knowledge and scientific data
Lead Institution:
University of Massachusetts – Dartmouth, School for Marine Science and Technology; Co-Principal Investigators: Steven X. Cadrin, Gregory DeCelles, and Douglas Zemeckis

Purpose: To map the spatial and temporal distribution of cod spawning on Georges Bank using existing scientific information and data acquired from interviews with current and retired fishermen who fish for cod on Georges Bank. The information is needed to better understand cod population structure and essential fish habitat in this region.

Project Title: Synoptic acoustic and trawl survey of winter-spawning cod in Ipswich Bay, western Gulf of Maine Lead Institution: Gulf of Maine Research Institute; Project Leader: Graham Sherwood
Purpose: To expand our knowledge of the winter-spawning component of Atlantic cod by conducting a synoptic acoustic and trawl survey of Ipswich Bay. Improved knowledge of spawning dynamics in this area will lead to more fine-scale (in both time and space) management options.

Project Title: Identifying offshore spawning grounds of Gulf of Maine winter flounder
Lead Institution:
University of New Hampshire; Project Leader: Elizabeth A. Fairchild
Purpose: To determine where winter flounder in the Gulf of Maine are spawning offshore and when, by studying their populations during the spawning season at offshore sites identified by commercial fishermen as locations where large numbers of adult winter flounder are seen during the spawning season.

 NEC/NEFMC – Cooperative Research Projects Funded 

These awards represent a continuation of the 2014 partnership established between the Consortium (NEC) and the Council. The NEC has representation from four research institutions: the University of New Hampshire, University of Maine, Massachusetts Institute of Technology, and the Woods Hole Oceanographic Institution, with Dr. Chris Glass at the University of New Hampshire, in the lead as its Director.

The Council is a group of 18 fishery officials that includes representatives from each New England coastal state, the federal government, and appointees from the region, all of whom are charged with managing the groundfish complex (cod, haddock, pollock and several species of flounder), in addition to other regional fish stocks. Funding collaborative research is fully consistent with its interest in understanding and improving this resource.
