Not a NZ salmon farm I will point out, but very interesting all the same.

Evolution at warp speed: Hatcheries change salmon genetics after a single generation

Evolution at warp speed: Hatcheries change salmon genetics after a single generation | Commercial fishing | Scoop.it
The impact of hatcheries on salmon is so profound that in just one generation traits are selected that allow fish to survive and prosper in the hatchery environment, at the cost of their ability to thrive and reproduce in a wild environment.

What Should Illegal Logging and Illegal Fishing Have in Common ... | Commercial fishing | Scoop.it
The value of the fishing and aquaculture industries exceeds US$190 billion annually and an estimated 240 million people depend on marine fisheries for their jobs. There's no doubt that oceans generate big business.

Warmer seas may raise mercury in fish | Climate News Network

Warmer seas may raise mercury in fish | Climate News Network | Commercial fishing | Scoop.it
Scientists in the US say they have found evidence suggesting that warmer sea surface temperatures may increase the ability of fish to accumulate mercury.This could present a risk to the health of some consumers of seafood as the mercury rises up the marine food chain.The scientists, based at Dartmouth College, New Hampshire, report their research in the journal PLOS ONE (Public Library of Science ONE).Until now science has known little about how global warming may affect mercury accumulation in marine life, and this is the first study to show the effects using fish in both laboratory and field experiments.The researchers studied Killifish, found in much of the world – but not in Australia, Antarctica or northern Europe – and living mainly in fresh or brackish water.They studied the fish under varying temperatures in the lab and in salt marsh pools in Maine. Fish in the marshes ate insects, worms and other natural food sources, while the lab fish were fed mercury-enriched food.The results showed that fish in warmer water ate more but grew less and had higher methylmercury levels in their tissues, suggesting that increases in their metabolic rate caused the increased mercury uptake.Mercury released into the air from industrial pollution can accumulate in streams and oceans and is turned into methylmercury in the water.Click headline to read more--

Promising solution: Bioplastic made from shrimp shells

Promising solution: Bioplastic made from shrimp shells | Commercial fishing | Scoop.it
"or many people, “plastic” is a one-word analog for environmental disaster. It is made from precious petroleum, after all, and once discarded in landfills and oceans, it takes centuries to degrade. Then came apparent salvation: “bioplastics,” durable substances made from renewable cellulose, a plant-based polysaccharide. But problems remained. For one, the current bioplastics do not fully degrade in the environment. For another, their use is now limited to packaging material or simple containers for food and drink. Now researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering have introduced a new bioplastic isolated from shrimp shells. It’s made from chitosan, a form of chitin — the second-most abundant organic material on Earth. Chitin, a tough polysaccharide, is the main ingredient in the hardy shells of crustaceans, the armorlike cuticles of insects, and even the flexible wings of butterflies. The Wyss Institute makes its shrilk from chitin from shrimp shells, most which would otherwise be discarded or used in fertilizer or makeup, and a fibroin protein from silk. Researchers discussed it in a March online study in the journal Macromolecular Materials & Engineering. Shrilk is cheaply and easily fabricated by a novel method that preserves chitosan’s strong mechanical properties. The researchers said that for the first time, this tough, transparent, and renewable material can be used to make large, 3-D objects with complex shapes using traditional casting or injection-molding techniques. That means objects made from shrilk can be mass-manufactured and will be as robust as items made with the everyday plastics used in toys and cell phones. “There is an urgent need in many industries for sustainable materials that can be mass produced,” Wyss Director Donald E. Ingber said in March. “Our scalable manufacturing method shows that chitosan, which is readily available and inexpensive, can serve as a viable bioplastic that could potentially be used instead of conventional plastics for numerous industrial applications.” This environmentally safe alternative to plastic could also be used to make trash bags, packaging, and diapers."

टिकाऊपण, लवचिकता आणि सक्षमता यामुळे प्लॅस्टिकचा वापर विविध क्षेत्रामध्ये मोठ्या प्रमाणात वाढला आहे. मात्र, त्याच वेळी त्याच्या अविघटनशीलतेमुळे प्लॅस्टिकचे प्रदुषणही वेगाने वाढत आहे. त्यामुळे विघटनशील असे जैवप्लॅस्टिक विकसित करण्यासाठी जगभरामध्ये सातत्याने संशोधन होत आहे. मात्र, सध्या उपलब्ध असलेलेजैव प्लॅस्टिकचा वापर अत्यंत मर्यादीत कारणांसाठी होऊ शकतो. त्यातही खाद्यपदार्थांचे पॅकेजिंग आणि पेयपात्रासाठी सामान्यतः केला जातो. तसेच हे जैव प्लॅस्टिकही अत्यंत कमी वेगाने विघटीत होते. या साऱ्या समस्यावर मात करण्यासाठी हार्वर्ड विद्यापीठातील वायस इन्स्टिट्यूट फॉर बायोलॉजिकल इन्स्पायर्ड येथील संशोधकांनी कोळंबीच्या कवचापासून जैव प्लॅस्टिक वेगळे केले आहे.

 

प्लॅस्टिकच्या अविघटनशीलतेमुळे होणारे प्रदुषण रोखण्यासाठी हे जैव प्लॅस्टिक अत्यंत उपयुक्त ठरेल.
