Close to 5,000 people gathered this past weekend, the culmination of a 500 km march, led by biologist Alexandra Morton, to protest open ocean fish farms and the impacts they are having on wild fish in British Columbia. As we open our doors to open ocean farms for ahi in Hawai’i, do we have something to learn from their experience in B.C.?

From Dr. Neil Frazer, a UH Professor (SOEST) born and raised in British Columbia:

In BC, native peoples (called “First Nations”) are very angry with farms. Near farms they have lost their subsistence fishing, their salmon and clams.

Many BC tourism companies are very unhappy because sportfish and wildlife have greatly declined near farms. Farmers have shot many marine mammals.

Salmon farming in BC is controlled by two large Norwegian companies: Marine Harvest and Cermaq.

First Nations from BC have gone to Norway twice to plead with the Norwegians to move their farms. Imagine native Hawaiians having to fly to Norway some day to plead for removal of farms.

Many lawsuits against sea-cage farmers are now in the BC courts. Solid citizens are marching down the highways in protest. It’s a mess.

Problems with sea-cage farms are not confined to BC. Many people in other countries are very unhappy with sea-cage fish farms.

Hawaii should look into it. Why import the mistakes of other countries?

The Pacific garbage patch is so large it cannot be precisely measured. It is estimated to be twice the size of Texas and  one of five in the world. Out of sight, out of mind? I think not.

Light bulbs, bottle caps, toothbrushes, Popsicle sticks and tiny pieces of plastic, each the size of a grain of rice, inhabit the Pacific garbage patch, an area of widely dispersed trash that doubles in size every decade and is now believed to be roughly twice the size of Texas. But one research organization estimates that the garbage now actually pervades the Pacific, though most of it is caught in what oceanographers call a gyre like this one — an area of heavy currents and slack winds that keep the trash swirling in a giant whirlpool.

PCBs, DDT and other toxic chemicals cannot dissolve in water, but the plastic absorbs them like a sponge. Fish that feed on plankton ingest the tiny plastic particles. Scientists from the Algalita Marine Research Foundation say that fish tissues contain some of the same chemicals as the plastic. The scientists speculate that toxic chemicals are leaching into fish tissue from the plastic they eat.

The researchers say that when a predator — a larger fish or a person — eats the fish that eats the plastic, that predator may be transferring toxins to its own tissues, and in greater concentrations since toxins from multiple food sources can accumulate in the body.

It may be out of sight, but it should be on your mind. After all, the effects could end up in your body. 

For the captain’s first mate, Jeffery Ernst, the patch was “just a reminder that there’s nowhere that isn’t affected by humanity.”
