Understanding the Impacts of Climate Change on Economically Important Fish Species

October 26, 2020 — The following was released by NOAA Fisheries:

Researchers at NOAA’s Southeast Fisheries Science Center and Atlantic Oceanographic and Meteorological Laboratory are teaming up. They want to understand how changing ocean conditions might be influencing commercially important fish stocks. The project will identify key physical processes that affect the biology and chemistry of waters used by coastal migratory species. They will pool their modeling capacities to investigate factors influencing fish stocks in the Gulf of Mexico and South Atlantic Bight. These stocks are managed by NOAA Fisheries and the regional Fishery Management Councils.

Building on previous research collaborations, the scientists will continue advancing these modeling efforts to support marine resources management and conservation. “We have configured several high-resolution models for the Gulf of Mexico, Caribbean Sea, and South Atlantic Bight,” said Laboratory scientist Dr. Sang-Ki Lee. “Using these models, we have built close collaborations between our laboratory and the science center addressing key scientific questions, including the impacts of increasing ocean temperatures on coral bleaching and spawning of Atlantic bluefin tuna in the Gulf of Mexico and Caribbean Sea, impacts of El Niño and increased rainfall on plankton patterns in the Texas-Louisiana shelf, and seasonal variability in ocean carbon chemistry in the Gulf of Mexico.”

Coastal migratory species, such as king mackerel, greater amberjack, red porgy, and red grouper, are key commercial and recreational species that support a billion-dollar economy. The most recent stock assessments for these species indicated that the stocks began declining in the late 2000s. This indicates either reduced population reproductivity, migration out of the management area, or both.

A stock assessment is the process of collecting, analyzing, and reporting demographic information to determine changes in the abundance of fishery stocks in response to fishing. They are also used to predict future trends of stock abundance. The stock assessments track the age structure of the adult population to determine how many new fish are expected in the future. When the actual number does not match the expected number, it reflects that something other than stock abundance is affecting the population, such as the environment or a predator species.

NMFS, SSA Report Poor Gulf of Mexico Shrimp Landings in July

August 29, 2019 — SEAFOOD NEWS — Shrimp landings in the Gulf of Mexico have been some of the worst in recent history, according to the Fishery Monitoring Branch of the NMFS Southeast Fisheries Science Center and the Southern Shrimp Alliance.

NMFS reported shrimp landings in the Gulf for July were only 7 million pounds, well below the 7.9 million pounds in July 2018 and the 8 million pounds in July 2017. The July commercial shrimp landings were 37.8 percent below the prior 17-year historic average of 11.3 million pounds for July.

Only 1.6 million pounds of shrimp were reported as landed in Louisiana — the third lowest volume for the state for a July in the last 18 years. All told, Louisiana landings were 62.1 percent below the prior 17-year historic average of 4.2 million pounds in July.

In Mississippi, only 415,000 pounds of shrimp were reported as landed, the second lowest total reported for any July from that state in the last 18 years, according to a Southern Shrimp Alliance press release.

For the year, landings of shrimp in Louisiana and the west coast of Florida are at the lowest levels they have ever been through the first seven months. Outside of 2010, the landings reported in Mississippi for the year are the lowest they have been in the past 18 years.

Shrimp harvests at historical levels in Texas and significantly above historical levels in Alabama have somewhat offset the low numbers from the rest of the Gulf, but landings in the region, at 35.6 million pounds, are the second lowest volume reported in the last 18 years.

Last month, NMFS reported ex-vessel prices for four of six count sizes of shrimp landed in the eastern Gulf (west coast of Florida) and five of six count sizes of shrimp landed in the northern Gulf (Alabama, Louisiana, and Mississippi). In the northern Gulf and western Gulf, the ex-vessel prices showed a large divergence between prices for large shrimp, U15, and all other shrimp. In the western Gulf, prices for U15 size shrimp were the highest reported for any July (not adjusting for inflation) in the 19-year database maintained by the Southern Shrimp Alliance.

Gulf of Mexico June Shrimp Landings Higher than in Previous Years; Overall Landings Still Down

July 26, 2019 — SEAFOOD NEWS — NMFS is reporting that shrimp landings in the Gulf of Mexico last month were slightly higher than in June last year and also in 2017 — but still below the 17-year historic average.

The Fishery Monitoring Branch of the NMFS Southeast Fisheries Science Center released shrimp landings data from the Gulf of Mexico for June 2019 this week. The data showed June landings of 11.1 million pounds were higher than the 10.9 million pounds in June 2018 and June 2017, the Southern Shrimp Alliance said in a press release.

The 17-year historic average for June is 16.7 million pounds.

Although landings volumes appear to have recovered somewhat in June, the commercial shrimp harvest remains substantially below previous years for the year so far. Roughly 28.6 million pounds of shrimp have been landed in the Gulf of Mexico since January, 34 percent below the 17-year historic average of 43.4 million pounds. It is also the second lowest amount reported for a January-to-June time period since 2002.

For 2019 thus far, the landings in Louisiana,10.5 million pounds, and the west coast of Florida, 2.0 million pounds, are the lowest reported in the historic dataset maintained by the Southern Shrimp Alliance, while landings in Mississippi, 1.1 million pounds, are the second lowest total reported.

Last month, NOAA reported ex-vessel prices for just two count sizes of shrimp landed in the eastern Gulf (west coast of Florida) and just three count sizes of shrimp landed in the northern Gulf (Alabama, Louisiana, and Mississippi). The ex-vessel prices reported for shrimp landed in the western Gulf (Texas) were roughly in line with the ex-vessel prices reported for the same count sizes in June 2018.

NOAA’s monthly reporting of shrimp landings in the Gulf of Mexico continues to include the disclaimer that the summaries collected or estimated from federal port agents may not reflect individual states’ landings.

As noted, the numbers reported – and the ex-vessel prices that have not been reported – over the last several months by NMFS appear to indicate that port agents may have been unable to collect information in the same manner as they have done historically, the SSA said in the statement.

Ex-vessel prices for 26-30, headless/shell-on shrimp in June show prices roughly the same as the historical averages, but more than $2 a pound less than the high prices reported in June 2014. June ex-vessel prices for U15 shrimp show a general increasing trend for northern Gulf and west coast Florida shrimp but a roller coaster ride for shrimp from the western Gulf. Still, the average ex-vessel price for June for U15 shrimp was $9.52 a pound for both western and northern Gulf shrimp, according to the SSA report.

October was record low month for US wild-caught shrimp in Gulf of Mexico

November 23, 2018 — It’s no wonder US wild-caught shrimp have been a little harder to find of late.

The 10.4 million pounds of shrimp caught by US commercial harvesters in the Gulf of Mexico during the month of October was the lowest for that month since records have been maintained, going back to 2002, reports the Southern Shrimp Alliance (SSA), a trade association that represents the harvesters.

Based on data provided Wednesday by the fishery monitoring branch of the National Oceanic and Atmospheric Administration’s Southeast Fisheries Science Center, total landings for the month were about 30% below the prior 16-year historical average (14.8m lbs).

In particular, the low volumes were driven by a lack of reporting of any shrimp landings from the west coast of Florida, as well as only 3.6m lbs reported as landed in Louisiana – by far the lowest total for any October going back to 2002 and less than half of the prior 16-year average (7.7m lbs) for the state, according to SSA.
