Fish Feed

Aquaculture is found world-wide but one irony of the industry is that often wild caught fish are used as feed for their farm raised cousins, which is both counter-productive and environmentally unsustainable. A recent breakthrough by scientists at the University of Maryland Center for Environmental Science’s Institute for Marine and Environmental Technology will make that vicious cycle a thing of the past.

“Aquaculture cannot sustainably grow and expand to meet growing global population and protein demand without developing and evaluating alternative ingredients to reduce fishmeal and fish oil use,” said the study’s lead author, Dr. Aaron Watson.

Supported by another paper published in the Journal of Fisheries and Aquaculture, the team has proven that a completely plant-based food combination can support fast-growing marine carnivores like cobia and gilthead sea bream in reaching maturity just as well as—and sometimes better than—conventional diets of fish meal and fish oil made from wild-caught fish.

Pulluvan Pattu is the music sung by the caste known as Pulluvas, which means lower caste. It is accompanied by hand-made stringed instruments such as Pulluva Veena.  In Kerala this is the traditional music is associated with the worship of Snake Gods.

Clothing Without Pretension

 

This may be the only time you find a link related to clothing on this site.  But it is not the clothing that motivates the link.  We liked the way this fellow explained his unique humility, so we have watched the same publication for more surprises.  Here is one. A man of considerable success and apparently little pretension. Artisan ethos.  Nothing about conservation, but a pretty clear sense of community (never mind the blue bloods and rock stars; it is the early morning conversations with the road sweeper that we can relate to) and at least with his five decades of marriage a clear sense of collaboration as well:

What’s the best thing and what is the weirdest thing you’ve ever received?

I have a fan that has been sending me things covered in stamps for over 20 years. I don’t even have any idea who it is, there’s never any letter. Around my desk at the moment I have a red watering can for the garden, a yellow sunflower, a bowling pin, a boat-shaped birdhouse, a yellow chicken and a long piece of wood, all covered in stamps with the address on it. So that’s just one crazy thing. But I get all kinds of things – I just had a little book sent to me, a story about me by a 10-year-old schoolgirl. Continue reading

Foraged Cuisine

The concept of ethical eating isn’t new to these pages and neither is the suggestion that cuisine might be the secret weapon in the fight against invasive species. So we were thrilled to read about chef, artist, environmentalist and social activist Bun Lai’s menus based primarily on what he can forage from his 100 acres of shellfishing grounds off of the Thimble Islands in Connecticut.

The kitchen is the perfect place to exhibit the spirit of exploration and creativity–why not exploit it as a method of controlling ecological pests?

Pondicherry is the capital city of “The Union Territory of Puducherry”, one of the famous tourist destinations in South India. The main attractions are the backwaters, palm-fringed beaches, fishing villages and the French boulevard town with its French heritage–not to mention the charming and picturesque beach side promenade. Pondicherry was the largest French colony in India with a long and interesting history of trade and war. Continue reading

Iceland’s Fearful Agencies at Work

Over the summer, several people have asked me, after I tell them what I’m researching, whether the books I’m looking at are actually enjoyable to read or just another dry primary source, as dreary and monotonous as many travelers found Iceland’s vistas during the eighteenth and nineteenth centuries. As with most things, the answer depends (largely on the book and certain chapters of each book), but for the most part I’ve flipped through hundreds of pages of travel literature with pleasure, not only because I know I’m being productive despite the beautiful day two floors above me outside Cornell’s Olin Library, but also because I find the Victorian British style of these authors–most of the works I’ve read so far were published between 1850 and 1880–quite engaging and fun to read.

Consider, for example, the following excerpts from Sabine Baring-Gould’s description of Námarskarð, an area full of hot mud springs in northern Iceland, in his 1863 book,  Continue reading

Chidambaram is uniquely interesting because it is the only temple complex to understood to be built primarily between the 12th and 13th centuries. This temple is dedicated to Lord Shiva. A huge Shiva Ganga tank is the one of the main attraction of this temple. Continue reading

Be, Cause (Simon Pearce)

This slideshow requires JavaScript.

He is an entrepreneur, so we find him interesting.  As with some other entrepreneurs featured on this podcast, we find him more interesting because of a higher calling in his business model.  He starts with excellence as defined by a few keywords–simplicity, quality, clarity, individuality, functionality–but he clearly cares about family and others outside his business. We find him most interesting because Simon Pearce contributes to the common good.  It is these ethics, not revealed directly in the From Scratch interview, but visible (though not “in your face” visible) on his company’s website, that make him worthy of more attention:

What Should We Expect of Solar?

I was pleased to see our fellow contributors give voice to the promising outlook of solar energy in a recent post. There is no doubt that this technology will be a game-changer for utilities in the coming century, and I’m excited to be a part of it. Last month, I was thrilled to start my first full-time position at SunPower Corporation, one of the largest solar cell manufacturers in the United States. Tempering that excitement was the knowledge that, at least for the short term, I wouldn’t be traveling to India to work with Crist and some of his wonderful staff. But let’s back solar.

This is every solar installer’s dream: a perfectly tilted, south-facing, non-shaded, sun-bathed roof.

Thekkady Nature in Focus

I’m a pediatrician by profession but a wildlife photographer by passion. They might not appear connected at first glance but the joy of being with children and the ability to be patient and understand their world has assisted me behind the camera in the field. Photographing animals has allowed me to use my expertise to get closer insights into their behavior.
The idea of having a photographic workshop in the lap of nature, in the Western Ghats with renowned wildlife photography guru Sudhir Shivaram was very exciting. I felt like a child waiting to get a new toy.

 

Thekkady-Kumily and the Periyar Tiger Reserve lie near the border between Kerala and Tamil Nadu. Periyar lake is an important watershed and a lifeline for wildlife in the region. The lake was created by the building of the Mullaperiyar Dam in 1895. What was started as a private game reserve became a wildlife sanctuary, and later the Periyar Tiger Reserve. While the area where the reserve is located is well-known as Thekkady, the town is named Kumily. It was a 5 minutes drive from our hotel to the PRT (Periyar Tiger Reserve) and from the entrance it’s a 500 meter walk to reach the boating jetty. From the jetty point, many visitors to the reserve take an hour-long boating safari where, with luck, the action along the bank can be viewed. For birders, most of the aquatic species can be expected, so luck is far less of an issue.

The evening of our arrival we had a workshop session during which our mentor gave us a good grip on exposure, metering, ISO and lots of inputs about the technical aspects of photography in general and wildlife photography in particular.

White-cheeked Barbet by Dr. Eash Hoskote - La Paz Group

White-cheeked Barbet

Early morning on the first day after a quick tea and snacks we headed out to PRT with all our gear. We were met by forest naturalists who were very well versed with the local conditions and the birding scene at that particular time of the year. We were given thick canvas knee-length “leech” socks which are dusted with tobacco powder, making them 100% leech resistant. We boarded a small raft driven by rope pulley to cross one of the many “fingers” of the many branched reservoir. After a brief time following the banks of the water we turned into the dense forest, where the penetration of morning sunlight was minimal. With such heavy equipment we really had to dodge the trees and hanging vines and made our way through the forest. The bird species sighted that first day were Malabar Trogon, White-bellied flycatcher, small blue kingfisher, spot-billed ducks, grey heron, Indian pond heron, little cormorant, white-cheeked barbet and a Malabar frog as an added bonus. It was a good 3 hr forest walk with birds chirping, frogs croaking and crickets making their presence felt. While just walking out of the PRT, we had a good sighting of a pair of grey Malabar hornbill with good photographic opportunity for all of us at close range. Our mammalian captures included a Malabar giant squirrel munching a nut and a group of Nilgiri langurs with young ones jumping around trees providing fantastic opportunities for dynamic shots.

What Would You Do For Perfect Coffee?

We appreciate those who make the effort to figure out the best way to make coffee, and especially those who share the art and science freely.  Here, from the Atlantic‘s website (always full of extras too eccentric or esoteric for the print version of the magazine) a bit from the science side:

It was November 23, 2010. We were in Surf City, North Carolina, getting ready to fortify ourselves before another grueling day. As the thin, black liquid oozed into the stained carafe, we stood bleary-eyed. We were roommates, Marine infantry officers, perpetually sleep-deprived from the training, the planning, the preparations for war. Back then coffee was little more than a bitter, caffeine-delivery system. It was just what we needed to stay awake.

We were missing so much. Continue reading

Scientific Findings About Those Famous Cousins

According to fable attributed to Aesop, there was once a country mouse who invited his cousin who lived in the city to come visit him…If you do not know that story, it is easy to find. The moral of that story seems to be that peace and quiet in the country ultimately provide a better life than the dangers of the city, no matter the attractions of the latter.  Hard to argue with that, unless you are a city mouse at heart.  And/or if your mouse brain has been hardwired that way. In which case, you can thank the tendency of humans to transform the natural environment into built space. Carl Zimmer explains recent scientific findings along these lines:

Evolutionary biologists have come to recognize humans as a tremendous evolutionary force. In hospitals, we drive the evolution of resistant bacteria by giving patients antibiotics. In the oceans, we drive the evolution of small-bodied fish by catching the big ones. Continue reading
