July 29, 2019 — SEAFOOD NEWS — Scientists at the NMFS Southeast Fisheries Science Center’s Galveston Laboratory have prepared the following information on prospects for the 2019 brown shrimp season (July 2019–June 2020) in the western Gulf of Mexico.
According to NOAA fisheries, although local environmental factors (temperature, rainfall amounts, and tidal heights) should have contributed to favorable conditions for brown shrimp recruitment and growth in Texas, freshwater inflow into Galveston Bay (on which the forecast model is based) from the Trinity River watershed resulted in salinities near zero in much of the bay. Subsequently, the availability of suitable nursery habitat was limited to West and Lower Galveston Bay. Likewise, growth may have been affected by the lower salinities.
They add, similarly, early spring temperatures in Louisiana would have suggested favorable conditions for an average production. However, Louisiana was inundated with freshwater runoff due to unprecedented Mississippi River flows this spring. These freshwater events have offset the early spring favorable conditions to a much less favorable environment for brown shrimp production.
Overall, the western Gulf of Mexico could expect an annual brown shrimp production of approximately 40.6 million pounds during the 2019–2020 season.
