Aquaculture Quotes

Merrill Meewee knew his stones. As a boy in Kenya, skipping stones was his favorite free-time activity. There had been an abundance of saucer-shaped missiles on the banks of his father’s own fishpond. Fat, river-smoothed disks, they skipped ten, twelve, sixteen times before slipping beneath the surface with a watery plop. His father, a man of little wealth but great forbearance, was not pleased with his boy’s solitary pastime, but he never ordered him to stop. Instead, he asked the boy how many stones he thought the pond could hold. I don’t know, Meewee remembered answering. A hundred thousand? Oh, such a big number! And how many stones do you suppose you’ve thrown already? Merrill, who was an excellent student, calculated the number of stones he might have tossed in an hour and how many free hours were left each day after school and chores, how many afternoons in how many years since he first discovered the sport. I would estimate 14,850, he informed his father with a certain amount of swagger. His father was impressed. So many? And all of them have gone to the bottom? Of course they’ve gone to the bottom, he had said, embarrassed by his father’s apparent ignorance. They’re stones. They’re heavier than water. And heavier than fishes? Of course heavier than fishes. Good, good, his father concluded, patting him on the head. Keep at it, son, and soon I won’t have to work so hard. Father? It’s true. When you fill up my pond with your stones, I won’t need nets and plungers to harvest the fish. I’ll simply wade up to my ankles and pick them like squash. It was a lesson in diplomacy, as much as aquaculture, and it stayed with him all these years.

The scariest thing is that nobody seems to be considering the impact on those wild fish of fish farming on the scale that is now being proposed on the coast of Norway or in the open ocean off the United States. Fish farming, even with conventional techniques, changes fish within a few generations from an animal like a wild buffalo or a wildebeest to the equivalent of a domestic cow. Domesticated salmon, after several generations, are fat, listless things that are good at putting on weight, not swimming up fast-moving rivers. When they get into a river and breed with wild fish, they can damage the wild fish's prospects of surviving to reproduce. When domesticated fish breed with wild fish, studies indicate the breeding success initially goes up, then slumps as the genetically different offspring are far less successful at returning to the river. Many of the salmon in Norwegian rivers, which used to have fine runs of unusually large fish, are now of farmed origin. Domesticated salmon are also prone to potentially lethal diseases, such as infectious salmon anemia, which has meant many thousands have had to be quarantined or killed. They are also prone to the parasite Gyrodactylus salaris, which has meant that whole river systems in Norway have had to be poisoned with the insecticide rotenone and restocked.

Increasingly, we will be faced with a choice: whether to keep the oceans for wild fish or farmed fish. Farming domesticated species in close proximity with wild fish will mean that domesticated fish always win. Nobody in the world of policy appears to be asking what is best for society, wild fish or farmed fish. And what sort of farmed fish, anyway? Were this question to be asked, and answered honestly, we might find that our interests lay in prioritizing wild fish and making their ecosystems more productive by leaving them alone enough of the time.

By 2030, says the UN Food and Agriculture Organization, fish farming will dominate fish supplies. Given how wrong the FAO has been in the past--saying catches were going up when, in fact, they were going down--this statement is worth examining carefully. When you do, you find it to be an observation of previous trends, not a reflection of what could happen or what people might want--in the same way as Red Delicious was once far and away the most popular apple in the United States because it was basically the only apple you could get. The FAO is simply observing that fish farming is the fastest growing form of food production in the world--growing at 9 percent a year and by 12-13 percent in the United States. Nobody is asking us whether we want this. It is just happening. The continued destruction of mangrove swamps in poor countries to provide shrimp for people living in rich countries is simply the market operating in a vacuum untroubled by ethics. It is a reflection of what will go on happening if we do not find ways of exercising any choice in the matter.

I will suggest that we do not only teach poor people how to fish but how to farm the fish—aquaculture!

The combined activities of our enormous population are already producing breathtaking effects. Our planet is only 12,700 kilometers in diameter—about three times the distance between New York and Los Angeles—and we can easily travel halfway around it in less than a day. We have turned much of its land surface into a patchwork of cities, industrial parks, farms, and rangeland. We have laid on this land a web of roads, canals, and pipelines. We have dug out of it hundreds of billions of tons of material, moved this material around, processed it, and dumped it. Our factory ships and trawlers crisscross the world’s oceans to exploit every valuable fishery. Our planes and satellites weave themselves around its sphere. We are moving so much rock and dirt, blocking and diverting so many rivers, converting so many forests to cropland, releasing such huge quantities of heavy metals and organic chemicals into air and water, and generating so much energy, carbon dioxide, methane, and nitrogen compounds that we are perturbing the deepest dynamics of our global ecosystems. Between one-third and one-half of the planet’s land area has been fundamentally transformed by our actions: row-crop agriculture, cities, and industrial areas occupy 10 to 15 percent of Earth’s land surface; 6 to 8 percent has been converted to pasture; and an area the size of France is now submerged under artificial reservoirs. We have driven to extinction a quarter of all bird species. We use more than half of all accessible fresh water. In regions of major human activity, large rivers typically carry three times as much sediment as they did in pre-human times, while small rivers carry eight times the sediment. Along the world’s tropical and subtropical coastlines, our activities—especially the construction of cities, industries, and aquaculture pens—have changed or destroyed 50 percent of mangrove ecosystems, which are vital to the health of coastal fisheries. And about two-thirds of the world’s marine fisheries are either overexploited, depleted, or at their limit of exploitation. The decline of global fish stocks has followed a predictable pattern: like roving predators, we have shifted from one major stock to another as each has reached its maximum productivity and then begun to decline.30

It's stunning how, under the weight of ecological collapse, a hundred years of culture can be gutted overnight. The metronome of our music and poetry isn't the ocean, it's fish. With cod gone meaning was swept away, dignity soon replaced with anger.

It is said give a man a fish, you would feed him for a day, but if you teach a man to fish you feed him for a lifetime. I say, Teach a wo(man) how to culture fish, you will empower the entire country

Hydrolectricity is the largest modern non-fossil source of primary energy; the combination of relatively low cost, high suitability to cover peak demand, and the multi-purpose nature of most large reservoirs (they serve as sources of irrigation and drinking water, a protection against downstream flooding, recreation sites, and, increasingly, places for aquacultural production) should make it one of the most desirable choices in a world moving away from fossil fuels.

No Fishermen , no fish.

I've swallowed fish-eyes whole like an endoscope. I once ate a trout cooked inside a dolphin. Felt like a shark eating another shark, inside the cold-blooded womb of yet another shark.

most respected broad certifications are those from the Marine Stewardship Council (MSC; the logo is a blue fish in the shape of a checkmark) for wild-caught fish, and Global Aquaculture Alliance’s Best Aquaculture Practices (BAP) for farmed fish.
