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.
- 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
- 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,
