Commission reduces mariculture fees, loosens triploid parentage rule to expand oyster aquaculture
Summary
The commission adopted rule changes reducing annual cultivated oyster mariculture fees and allowing Atlantic/Gulf Northern broodstock to be used for triploid seed, moves intended to lower barriers for small growers and improve seed availability.
The Texas Parks and Wildlife Commission on May 22 adopted rule changes that lower annual fees for cultivated oyster mariculture permits and expand allowable broodstock origins for triploid oysters to include Northern Gulf states (Texas, Louisiana, Mississippi and Alabama).
Dr. Lindsey Glass Campbell of the Coastal Fisheries Division presented the two items. Staff proposed lowering annual fees for grow‑out and nursery hatchery sites to $150 per acre per year for public water and $57 per acre per year for private‑water portions; staff said a minimum fee remains for very small hatcheries to help cover inspection costs. Campbell said the change responds to industry input and is intended to encourage small business growth.
On parentage for triploids, staff recommended allowing triploid seed produced from Northern Gulf broodstock so growers have more suppliers. Tracy‑style triploids are desired for faster growth and year‑round meat quality; staff said origin documentation and biosecurity testing remain required.
The rule changes were supported by the Oyster Advisory Committee and the Texas Conservation Alliance. At the public meeting on the fee change staff recorded 18 comments (14 supportive, four opposed or asking for different fees); for triploid parentage there were 15 comments (14 supportive). Two industry speakers — Jim Mein of PMAR (a Texas hatchery nonprofit) and David Aparicio of Oyster Brothers — urged the commission to approve the changes, saying more seed suppliers and lower fees will help new growers enter the market.
Commissioners asked questions about regional production and regulatory overlap. Campbell said other Gulf states have more permitted acres and longer‑established mariculture programs; Alabama, Mississippi and Louisiana reported hundreds of permitted acres in their programs. The commission approved the amendments by unanimous voice vote.
Staff said broodstock origin must still be documented and biosecurity testing will continue to be required.
