August 2021 PACK Meeting overview

Hey all, If you missed the meeting, here are a few key points from our speaker, Bill Rodney, this past Tuesday. The discussion was mainly about the state of oyster fisheries in Galveston Bay and efforts taken to rebuild them.

 

Club Business

  • Elections for board positions are coming in a few short months, so if you feel like you can/want to contribute to PACK, consider running for a position. The president position will also be open this election, so we will be needing a new one after this year. 
  • Upcoming Trips

Speaker Notes

  • Restoration Projects (click for the link for location - sourced from a Hook-n-Line Map (FULL MAP))
    • Frenchy’s Reef - located a few miles west of Frozen point, this is a grouping of reefs that had restoration efforts done
    • Dollar Reef - This is another well-known reef that is a mile or two NE of Moses Lake that has somewhat declined from oystering that was rebuilt to allow for more oyster growth
    • Eagle Point Reef - This is located just west of Red Fish Island that was included in one of Bill’s first restoration efforts.
    • Middle Reef - As of this meeting, Middle Reef is in the sweet spot for salinity, and a 5” layer of river stone was dropped (20 acres), allowing for spat (juvenile oyster larvae) to form new reefs.
    • Hannah Reef - Hanna Reef is one of the more well-known reefs in Galveston with a large natural reef. Next to the reef, a rectangular plot of a new oyster reef was created. This was a larger project, partly funded through Deepwater Horizon
    • Peppergrove Reef (1)  (2)  (3) - This cluster of reefs NW of Goat Island got hit fairly hard by Ike and restoration funds from the Deepwater Horizon allowed for more reef construction in the area.
    • Pasadena Reef - This reef is closer to the middle of Galveston Bay and 10 acres of new, thick domed reefs were added to this area, which makes this a unique reef with plenty of habitat for both fish and oysters.
    • Todd’s Dump - This slightly more recent restoration right off of Eagle Point in San Leon. A new method of reef development using mounds was utilized which helps juvenile oysters (spat) better cling to the rocks that were dumped there. This reef also has a depth gradient, as the north end is shallower, gradually getting deeper to the south.
  • General Oyster info I found interesting
    • Salinity-wise, oysters thrive in between 10-20 PPT (parts per thousand), meaning that closing off Rollover Pass allowed for a less saline environment for oysters to thrive in.
    • Oyster harvesting boats can have up to an 80% reduction of harvestable oysters on a given reef. Oyster season in Texas spans from November 1st to April 30th and opening day can have hundreds of boats congregated on a given reef.
    • Data he collected before and after constructing a reef had an increase in biodiversity for that area, indicating a healthier ecosystem.
    • The reason Ike was so much more destructive to oysters was because of the debris that was moved due to the storm surge, which essentially buried the oysters in silt/mud. Most reefs constructed were in efforts to "revive" the reefs destroyed from this hurricane.
    • When scanning for oyster reefs, a depth finder with side-scan is a powerful tool and it allows you to not only see the reef but how dense it is as well.

Sorry this is coming out a bit late,

Ryan W.
