Whether or not you like them or hate them, you possibly can’t deny that oysters are a staple within the Gulf Coast weight-reduction plan. That’s why it’s large information that Texas will lastly be allowed to participate in and financially profit from oyster farming.

Solely this sort of farming doesn’t contain tractors, seeds or soil, says Texas A&M College at Galveston Seafood Security Lab Supervisor Mona Hochman ‘94.

“Suppose floating cages, longlines and a visibly segmented space inside a bay,” she mentioned.

As supervisor of Texas’ solely oyster-testing lab, Hochman is  conscious of the myriad points related to consuming oysters and the way correct development and harvesting strategies can translate to the brand new oyster farming business.

The farming course of largely makes use of floating cage, from which the oysters will be harvested as soon as they attain the suitable dimension. Nationally, the farmed or cultured oyster business generates within the a whole bunch of tens of millions of {dollars}. In Texas, the apply might change into equally worthwhile.

All through the opposite gulf states, Louisiana, Mississippi, Alabama and Florida, this apply is already pretty commonplace. However for Texas, the final state within the gulf to legalize off-bottom oyster mariculture, the method continues to be being put in place and laws are nonetheless being cemented.

Simply final month, the Texas Parks and Wildlife Fee (TPWD) accepted a algorithm for oyster mariculture, laying the groundwork for the state’s latest business. Thus, Texans at the moment are in a position to apply for permits permitting for the lease of public water for farming functions. That mentioned, the places of those operations will have to be accepted by TPWD and different state companies, and farmers shall be topic to annual charges, obligatory transport paperwork, reporting necessities and different laws set forth by each the state and federal governments regarding security precautions.

Hochman says Texas might’ve been late to the sport for numerous causes, together with provide and demand, hurricanes, and the massive funding crucial to interrupt into the business.

“Texas bays traditionally have been mass producers of untamed oysters, that means we didn’t want oyster farms,” she mentioned. “In 1999, roughly 6.four million kilos of oysters have been harvested from Texas bays, with 95% of that popping out of Galveston Bay. Following Hurricanes Ike and Harvey, Galveston Bay has suffered nice loss in pure oyster beds resulting from siltation and influxes of recent water.”

The Nationwide Oceanic & Atmospheric Administration (NOAA) echoes Hochman’s sentiments. In response to a current report, international wild oyster harvests have declined by 43% since 2000, seemingly prompting the necessity for alternate avenues of manufacturing.

Hochman says that as a result of the oysters will seemingly be suspended in floating cages, they received’t be topic to siltation, which is once they change into lined by sediment like mud, sand or different pure and unnatural particles. Siltation can come from runoff because of storms or hurricanes, and even from vessel site visitors in close by waters.

“These culturing methods will be positioned in areas with optimum water situations (circulation price, vitamins, and so forth.) and moved if crucial,” Hochman mentioned. “Cultured oysters develop individually, versus being in a conglomerate when wild (with many oysters connected to one another). These particular person oysters are in a position to develop with a deeper cup and extra uniform shell, which is most popular by the restaurant business and oyster connoisseurs. Moreover, oysters cultured within the water column are much less more likely to home or change into prey for benthic worms and crabs.”

Hochman additionally says one of these farming or culturing system permits for the cages holding the oysters to be lifted out of the water intermittently to cut back biofouling, when microorganisms like algae or animals like barnacles can develop on the oysters’ shells.

As for the opposite marine life like corals, fish and even birds that may very well be impacted by these watery farm areas, the state additionally has that lined.

“TPWD can also be setting a large number of laws concerning the place farming can happen primarily based on the pure substrate, oyster reefs, seagrass beds, and so forth. They are going to be regulating all oyster farming and, I consider, be at the very least partially answerable for granting permits to farm,” she mentioned.

Additional making farming engaging is decreased development time.

Whereas wild oysters usually take 18 months to 2 years to achieve harvestable dimension, Hochman says the cultivated oysters will seemingly be harvestable inside a 12 months’s time, although after sure strains are established.

“As a result of cultivated oysters shall be triploid (sterile) they’ll commit all their vitality to rising as an alternative of copy, permitting them to develop sooner. Additionally, cultured oysters shall be legally harvestable at 2.5-inches, whereas the restrict for wild oysters is 3-inches,” she mentioned.

Final is the problem of meals security, about which Hochman mentioned she’s not too nervous.

“The general public who will seemingly start with these methods are already oyster harvesters themselves who’re conscious of the problems with micro organism and different ailments,” she mentioned. “In any occasion, the Seafood Security Lab is out there to work with oyster farmers to make sure they’re producing a secure product for the consuming public.”
