grass carp farming

I’ve always liked pasture, especially with real, native, mixed species hedgerows and the occasional mature native tree in the field.
There’s lots of beef and sheep farming hereabouts (North Cornwall), which is fine, but:
a. In an overpopulated world, 500 lbs of of meat per acre every other year seems a small crop;
b. Small farms are failing, because the profit per acre is miniscule with large supermarkets driving the price down. Hence less people are able to farm, and there’s the danger that agriculture will follow the U.S.

Grass Carp
Cold-blooded fish are the most efficient means of turning vegetable protein into animal protein, and most fish are low-fat, healthy alternatives to lamb, pork, most beef (exceptions being silverside, top rump … which are very lean).
Imagine a small grass farm, cutting grass to feed a large pond of grass carp. An electric pump to aerate the water; another pump to pump the soiled water back onto the grassland and fertilise it.
The fertility in the pond water would keep the grass growing organically with no need for chemical fertilisers.
A fresh water supply would be necessary to keep the pond toppped up, and both pumps could be powered by photovoltaic cells, because in the winter the grass hardly grows and carp barely feed.
Young grass carp can be bought in the U.K. for about £3 each. The price is lower when buying more fish.
They prefer fairly slow running water or ponds, except for breeding, and can grow very quickly in ideal conditions: from 8 inches (20 c.m.) to 18 inches (45 centimetres).
Adult grass carp can reach 40 lbs (about 17 kilograms) bodyweight.

Of course, if you have a lawn, you could probably keep your own grass carp, and farm your own high-quality protein.

Aquaponic Gardening: A Step-by-Step Guide to Raising Vegetables and Fish Together

Aquaponic Gardening - Sylvia Bernstein
A highly rated book by Sylvia Bernstein, released in March 2013, and already on offer at Amazon.
The publishers blurb says this:
Aquaponics is a revolutionary system for growing plants by fertilising them with the waste water from fish in a sustainable closed system. A combination of the best of aquaculture and hydroponics, aquaponic gardening is an amazingly productive way to grow organic vegetables, greens, herbs and fruits, while providing the added benefits of fresh fish as a safe, healthy source of protein. On a larger scale, it is a key solution to mitigating food insecurity, climate change, groundwater pollution and the impacts of overfishing on our oceans. This is the definitive do-it-yourself home manual, with an introduction by Charlie Price, head of Aquaponics UK. It focuses on giving you all the tools you need to create your own aquaponic system and enjoy healthy, safe, fresh and delicious food all year round. Starting with an overview of the theory, benefits and potential of aquaponics, this book goes on to explain: system location considerations and hardware components; the living elements – fish, plants, bacteria, and worms; and, putting it all together – starting and maintaining a healthy system. Aquaponics systems are completely organic. They are four to six times more productive and use 90 percent less water than conventional gardens. Other advantages include no weeds, fewer pests, and no watering, fertilising, bending, digging, or heavy lifting – in fact, there really is no down side! Anyone interested in taking the next step towards self-sufficiency will be fascinated by this practical, accessible and well-illustrated guide.

  1. At last – about 40 years after I fancied the idea – I have 5 grass carp. Tiny little creatures, but I'll enjoy watching them grow.

    I have some wheat germ, which is a recommended food for the very young fish, but they are already eating the pond weed. I have to grow replacement pond weed in a separate tiny pond because they strip the leaves off the weed in their pond.

  2. aquatic #biodiversity in Georgia New maps show Southeast streams teeming with life conservation Georgia

    Now, thanks in part to a local organization, freshwater biologists have a set of detailed maps showing where that diversity is strongest and where it is most endangered.

    Biologists from the Tennessee Aquarium Conservation Institute in Chattanooga and the University of Georgia's River Basin Center worked on the project with grant funding from the National Fish and Wildlife Foundation.

    "Freshwater doesn't have large, charismatic animals," George said. "There aren't whales and dolphins, but what we do have is like a rainforest, where all these different species add up together for something beautiful and unique.

    It's a point of pride, and what this work does is make it a little more easily understandable to people that aren't scientists that we have this incredible biodiversity in the south."

    Nearly two-thirds of the country's fish species are found in the Southeast. So are almost half of the world's crayfish species and 90 percent of the nation's mussel species.

    The project relied on the Conservation Institute's regional connections to gather data from museums, researchers, government reports and other agencies across 290 watersheds to be used in formulating the maps.

  3. #growyourown #gardens Grow your cherry tomatoes on the commute with Ex-Countryfile presenter Julia Bradbury

    Family gardening or ‘community gardening’ is becoming a huge project for urban cities as they tackle the lack of accessible green space by introducing pop up gardens. That’s exactly where Julia is today thanks to a partnership between the Honest organic tea company and national charity Groundwork. She explains, “Right now I’m standing on a building site in Stratford where we’ve got a temporary garden. I’m surrounded by gorgeous railway sleepers and boxes of curly Kale and beetroot. The birds are singing while the building cranes are in the background, it’s a real juxtaposition of urban and green space.”
