Growing Food and Fish at the Same Time

Posted in Uncategorized, tagged , , , , , , , , , , , , on September 18, 2015| Leave a Comment »

I liked this Marketplace radio story on Duluth, a very cold place where people are managing to grow lettuce and fish in the same water year-round.

Chris Julin reports, “Tony Beran is standing in the kitchen at the Lake Avenue Restaurant in Duluth, Minnesota, with a head of romaine lettuce in one hand and a clump of curly lettuce in the other.

” ‘They’re beautiful,’ he says.

“Beran’s the executive chef, and one thing he likes about these bunches of lettuce is how clean they are. ‘They’re grown aquaponically instead of in dirt,’ he says. ‘Which is wonderful in the kitchen. It’s less labor for us.’

“Another thing he likes about this lettuce is that it was grown just up the road. The restaurant features local ingredients, and Beran serves locally grown lettuce all year, which is a bit of a trick in a place like Duluth. Last winter, the temperature was below zero 23 days in a row.

“But it’s always warm in the greenhouse at Victus Farms, where Beran’s lettuce came from. It’s about an hour’s drive from Duluth in a little mining town called Silver Bay.

” ‘These are all our babies,’ says Mike Mageau, as he shows off his latest lettuce crop. [He’s a] professor of geography at the University of Minnesota Duluth. He runs a program in environment and sustainability, and this indoor farm is a research project. …

“Most of Mageau’s lettuce is floating. Each plant is stuck into a hole in an inch-and-a-half-thick sheet of polystyrene foam. The foam rafts float in pools in the greenhouse, and the lettuce roots dangle through the foam into the water.

“The fish live in a neighboring room. They’re tilapia, and they swim in nine round plastic tanks, each one about six feet tall. Waste from the fish gets pumped over to fertilize the plants in the greenhouse, and some of the pools in the greenhouse grow algae and duckweed that come back into this room to feed the fish.”

Learn more about this continuous loop and the cost to set one up at Marketplace. People commenting on the website say the concept isn’t new, but it was new to me.

Newly Freed River in Maine

Posted in Uncategorized, tagged , , , , , , , , , , , , , , , , , , on September 7, 2015| Leave a Comment »

Casey Kelly has a story at WBUR’s Only a Game on a sport enabled by the removal of dams on the Penobscot River in Maine.

“The recent removal of two dams (and upgrades to others) in Maine’s Penobscot River made available over 1,000 miles of habitat for Atlantic salmon and other fish — and also made the river available to whitewater enthusiasts.

“The dam removal was the culmination of years of restoration efforts by several groups. The Penobscot Nation, for whom the river has been vital for centuries, helped lead that effort.

“ ‘The creator put us here, in the Penobscot River Valley,’ said James Eric Francis, Sr., the director of cultural and historic preservation for the Penobscot Nation. ‘We are surrounded by the sacred river.’

“Last month, paddlers from all over the country gathered for a race celebrating the removal of the dams.” More here, including a video.

Here’s how freeing the river came about. It was a major collaboration by disparate groups committed to identifying and acting on the values they held in common.

The dismantling of the Veazie Dam is also giving 11 species of fish better access to 1,000 miles of spawning habitat.

Anglerfish use bioluminescence to attract their prey in the darkest depths of the ocean.

When John was little, he liked a book called Fish Do the Strangest Things. Strangeness is a great focus for a nature book, because everyone likes offbeat critters.

Steve Curwood, founder of the radio show Living on Earth, recently interviewed the author of a book that focuses on the strangeness of ocean life.

CURWOOD: “In an engaging new book called The Extreme Life of the Sea, biologist Steve Palumbi and his novelist son Tony deepen our understanding of how strange sea life has managed to survive against all odds. … Why did you write this book. Why now?

PALUMBI: “Well, the real reason is that we’re trying an experiment: can you take the narrative style and approach that a novelist would use and combine it with what a scientist would do? … You don’t really care about the plot until you care about the characters, and so we wanted to write a book that made you care about the characters.

CURWOOD: “Now, you write about the extreme life of the sea, the oldest, the hottest, the shallowest, to name a few. Why did you choose this approach?

PALUMBI: “Because it was a way of getting people’s attention to the really sort of amazing things that these critters do. Organisms in the sea live in some of the hottest places, they live in some of the coldest places, and how they do that is something marine scientists have paid a lot of attention to. So it was really a way to make it more engaging, more fun, and to let us move credibly between different kinds of organisms all in the same chapter. …

CURWOOD: “You had one extreme that you called immortal.

PALUMBI: “That’s an amazing jellyfish called turritopsis, and it has the remarkable ability to age in reverse. So when the environment is bad, this animal can essentially go from its adult body form back, back, back to its larval form, and then start all over again. … It’s called transdifferentiation. It’s the only critter known to be able to do that.”

More here, where you can read the rest of the transcript and listen to the recording. It’s all pretty amazing.

Isle of Eigg Says No to Fish Farm

Posted in Uncategorized, tagged , , , , , , , , , , , , on September 9, 2011| 5 Comments »

In case you just tuned in, this blog was started at the invitation of my daughter, who is the founder of the birthstone-jewelry company Luna & Stella. Sometimes I blog about the jewelry, but Suzanne told me to write about whatever interests me. Already a customer who was previously wary of online purchasing found the blog and wrote Suzanne that it helped her decide that Luna & Stella was good people.

The blog is currently housed at WordPress, which makes life easy for a neophyte like me. One thing that is fun at WordPress is clicking on posts from the other bloggers, posts that are on the Freshly Pressed page or found by clicking on a key word at the Tags page.

Today I got quite interested in an entry from a WordPress blogger in northern England who calls herself Heather Uphillanddowndale. She shows her photographs of a lovely Scottish island and talks about its fight against a major commercial fish farm.

I used to think fish farms made a lot of sense, but lately I have read about possible environmental damage and overcrowding that can spread disease to wild fish.

Heather quotes from a statement by island residents: “Highland Council has recently received an initial application to site a fish farm off the east coast of Eigg, north of Kildonan. The site identified covers an area extending to 20ha (this equates to 28 football pitches) & would consist of 14 x 30m diameter cages which would be serviced by a 10m x 10m permanently sited barge (powered by diesel generator).

“The community has considered this proposal at length. The outcome of the resulting ballot which had an 86% turnout was 97% against the development.

“Eigg lies within the Small Isles National Scenic Area. A large fish farm would have a considerable negative impact on the approach to the island and could also impact negatively on the peace and quiet that visitors seek when they come to the island, as well as on the quality of life of nearby residents.” Read more at Uphilldowndale.

Buying Fish Directly from Fishermen

Posted in Uncategorized, tagged , , , , , , , , , , , , , , , , , , , on August 17, 2011| 1 Comment »

I had heard about community-supported-agriculture-type efforts that deliver fish directly to consumers in the Greater Boston area. Very fresh. What I did not know is that this sort of initiative is taking place on a wider scale.

My husband recently pointed out a NY Times story on how professional Rhode Island fishermen have made it easy for chefs to buy directly from the daily catch. And according to the Times, the chefs are ecstatic.

“This boat-to-table initiative is part of Trace and Trust, a program that [Point Judith-based fisherman Steve] Arnold; Christopher Brown, the head of the Rhode Island Commercial Fishermen’s Association; and Bob Westcott, another local fisherman, started this year to make fishing more lucrative and shopping more reliable. …

“Trace and Trust comes at a moment when the seafood industry is under attack because of misleading labeling as well as the freshness and sustainability of what it sells. Consumers and fishermen have reacted by setting up community-supported fisheries, in which consumers pay in advance for a weekly delivery of seafood. And fishermen have reached out to chefs before. But Trace and Trust has used technology to create a more direct and responsive connection between consumers and fishermen than any other program in the country, said Peter Baker, director of Northeast Fisheries Program for the Pew Environment Group.”

Because of the field I’m in, I do have to spare a thought for the fish-processing jobs that may be lost with more of this direct marketing, but there is no doubt that for the fisherman, the consumer, and the restaurant, fresh is best.

Here’s a picture I took of the Point Judith (RI) fishing fleet at rest.
