Where the gringa lives in the gulf coast of Texas, oyster farming is big business. The gringa’s farming experience is limited to my father’s cattle ranch and my own egg farming. Is that how oyster farming works? Do you just leave the little guys alone most of the time to do what oysters do? Toss them a bit of feed, protect them from predators, stuff like that? Well, actually oyster farming has gone hi-tech. For young people who are interested in a beach bum lifestyle with the edge of technology, oyster farming or working with the technology related to the industry may be your thing if you love science as much as beach bumming.
Oysters don’t need their human overseers to bring them a bale of hay or toss out some nutrient enriched scratch. They are living filters that live on the bottom of a bay. Oyster farmers really don’t have that much to do, it would seem, unless it is harvest time. Sounds like the perfect beach bum job.
However, there is one thing that can happen that can interrupt an oyster farmer’s hiatus between harvests. If storm clouds gather, oyster farmers have to get out of their hammocks, put away the surfboard and forego the margaritas and head out for some serious relocating work in the estuaries.
You see, as bottom feeding filters, rain in this polluted day and age can be deadly for oysters. And even if contaminants in run off don’t kill the slimy, little buggers they could, in turn, kill a human if eaten. A local thunderstorm with a heavy downpour means one of two things:
- Completely relocate their stock, or,
- Quarantine the area and delay harvest until it is safe.
Now, even if an oyster farmer was willing to relocate their oysters, often weather conditions can change rapidly and unexpectedly in coastal regions. Usually an oyster farmer simply doesn’t have enough time to respond. So, the oysters bide the storm and everyone hopes for the best. But considering how heavily polluted most of the soil is in populated areas around the world, it’s usually not good news when it’s all over.
The gringa doesn’t have the numbers for industry loss or farm closures in the Gulf of Mexico area I call home. However, I can tell you about what’s been going on in Tasmania. Since 2013 industry research has recorded a loss of over $4.3 million (Australian currency!) for Tasmanian oyster farmers due to contamination related farm closures, caused by pollutants in rainfall water runoff that entered estuaries. This sounds awful, right? Well, take heart, dear readers. There is good news for Tasmanians as well as oyster farmers everywhere thanks to an agriculture technology start-up company, The Yield.
The Yield has designed a system of sensors that were tested in 14 Tasmanian oyster farm estuaries. This comprised about 80% of the entire oyster industry for the state. The technology measured:
- Water depth
- Barometric pressure
Oyster farmers use their smartphone, or other device, to access the handy little app that is updated every five minutes with new data about their squishy, little, hard-shelled babies. Access is also available to food safety regulators so everybody that matters is in the loop.
But the gringa wants to know if this has made oyster farming better. I mean, it’s always fun to have new gadgets but where business is concerned, is there a point to the expense? Here are the benefits of this new technology:
- Reduces paperwork between farmers & food service regulators.
- Food quality and safety has improved.
- Accurate measurements has resulted in fewer farm closures.
- Fewer farm closures has resulted in higher production, yields and profits.
Well, it looks like this technology is worth the investment for oyster farmers. It also looks like the investment of time and effort of scientists and meteorologists for more than a century was also a worthy investment. That is the backbone of the information that went into designing this system. If you have a habit or hobby of recording weather related “stuff”, who knows, one day what you may consider a hobby or pre-occupation could change the world! More than a hundred years worth of weather and tidal related data helped developers understand weather and tidal patterns, how they changed with the seasons, and how this would affect the performance of the technology to predict weather events. So, basically, Tasmania’s oyster farmers are more successful because of digital fortunetellers.
