Fatty Acid Dynamics In The Fish Gulf Menhaden

March 6, 2019 — “Essential fatty acids” are critical to organismal growth and development and, because they cannot be synthesized, they must be obtained through the diet. The role of essential fatty acids have been known to the medical community for decades – these components of the diet play a critical role in human health, growth, and development.

The well known omega-3 fatty acids are one example and are used to reduce the risk of heart disease, pain from rheumatoid arthritis, and depression. Other animals, like fishes, also rely on essential fatty acids for their growth and development, and the importance of fatty acid composition is critical in the success in aquaculture because they play an important role in growth, reproduction, and swimming abilities of fishes.

Omega-3 fatty acids like EPA and DHA have recognized physiological functions and are critical during endogenous and early exogenous feeding. Poor growth and survival may occur without sufficient levels of essential fatty acids. Because these biological precursors are so important to organismal development, we sought to describe the intra-annual changes in the fatty acid composition of Gulf Menhaden. This small fish is termed a “forage fish” because it is thought to be a major prey item, and a major ecological role, to a variety of avian, fish, and mammal predators. The Gulf Menhaden stock also supports the largest commercial fishery in the Gulf of Mexico. This fishery is a called a “reduction” fishery because it converts the live fish to both fish oil and fish meal. Fish oil from Gulf Menhaden is rich in EPA and DHA and is widely used for human consumption. Similarly, the fish meal produced is used in a variety of aquaculture and agriculture applications. The implications of seasonal variation in the characteristics of fish oil and fatty acid composition have implications to the dynamics of the reduction fishery as well as to the predators that rely on Gulf Menhaden. In this work, we describe general and specific characteristics of oil content and fatty acid composition of Gulf Menhaden.

Fish shrinking as ocean temperatures rise

October 4, 2017 — One of the most economically important fish is shrinking in body weight, length and overall physical size as ocean temperatures rise, according to new research by LSU Boyd Professor R. Eugene Turner published today. The average body size of Menhaden—a small, silver fish—caught off the coasts from Maine to Texas—has shrunk by about 15 percent over the past 65 years.

Menhaden make up about one-half of the Atlantic and Gulf of Mexico fish harvest and had a dockside value of about $129 million in 2013. They are coastal species that spawn offshore and move to estuaries where juveniles grow to one- and two-year old fish. The air and off the Atlantic coast and the Gulf of Mexico has steadily increased, especially in estuaries, where heat exchange occurs efficiently between air and sea. Adult menhaden return offshore where they are harvested with purse seine nets.

U.S. Gulf and Atlantic Menhaden Fisheries Enter MSC Sustainability Assessment

HOUSTON — June 15, 2017 — The following was released today by Omega Protein:

Last week, the Marine Stewardship Council (MSC) announced that the U.S. Atlantic menhaden and U.S. Gulf of Mexico menhaden fisheries have entered the evaluation process in order to acquire the respected blue ecolabel for sustainable fishing. The assessments are being conducted by third-party independent auditors SAI Global at the request of Omega Protein.

Atlantic Menhaden

Atlantic menhaden (Brevoortia tyrannus) are small, oily fish that are caught commercially in a fish meal and fish oil fishery and a bait fishery. They appear in estuaries and coastal waters from northern Florida to Nova Scotia. While considered unfit for direct human consumption, menhaden caught via the modern purse seine method are used in fish meal and fish oil for human and animal nutrition, due to their high natural concentration of healthy omega-3 fatty acids. Menhaden are also valuable as bait for fishermen targeting other commercially valuable species, such as lobster.

Gulf Menhaden

Gulf menhaden (Brevoortia patronus) have a similar biology to Atlantic menhaden and are also caught in both a fish meal and fish oil fishery and a bait fishery. They have a Gulf-wide range, from the Yucatan Peninsula in Mexico, across the western and northern Gulf to eastern Florida. Adults are found in nearshore waters and lower bays, while juveniles are found in fresh and brackish estuaries and rivers.

The Second Largest U.S. Fishery

Between the Atlantic and Gulf Coasts, the U.S. menhaden fishery is the second largest in the country by weight, trailing only Alaska pollock. The purse seine fishery is notable for being extremely clean; according to the National Oceanic and Atmospheric Administration’s Chesapeake Bay Office, it is “one of the most selective, and effective fisheries,” as evidenced by an insignificant bycatch.

Commercial landings of Atlantic menhaden peaked in the 1950s, while commercial landings of Gulf menhaden peaked in the early 1980s. Harvest levels of menhaden have significantly decreased, essentially tracking fishing effort, since those high points, and the most recent stock assessments of Gulf menhaden and Atlantic menhaden confirm that neither species is undergoing overfishing or being overfished.

Statements from Omega Protein and MSC

“The MSC blue ecolabel is the gold standard for sustainable fishing worldwide. We are extremely proud of the work we’ve done to conduct our fishing operations sustainably, and we’re excited to share this work with the auditors as they undertake this assessment to the MSC Standard,” said Ben Landry, the Director of Public Affairs for Omega Protein. “We are confident that the menhaden fishery will meet the MSC Standard, recognizing its advances in responsible harvesting methods as we continue to pursue the most sustainable fishing practices available.”

“We welcome the U.S. Gulf of Mexico and Atlantic menhaden purse seine fisheries’ decision to enter MSC assessment,” said Eric Critchlow, MSC U.S. program director. “This is an important milestone for the MSC and for fishing in the United States.”

MSC’s Standard for Sustainable Fishing

The MSC Fisheries Standard is designed to assess the sustainability of fishery practices and management methods. The standards used to evaluate fisheries have been developed in deliberation with scientists, industry, and conservation groups, and reflect the most up-to-date fisheries science and management practices.

The MSC Standard is based on three core principles that every fishery must meet in order to be MSC certified:

  1. Sustainable fish stocks: Fishing activity must be at a level which ensures it can continue indefinitely.
  2. Minimizing environmental impact: Fishing operations must be managed to maintain the structure, productivity, function, and diversity of the ecosystem.
  3. Effective Management: The fishery must comply with relevant laws and have a management system that is responsive to changing circumstances.

The assessment is being carried out by the certification body SAI Global Assurance Services and has an expected completion date of December 2017. The MSC assessment process is open for public input. Those interested in the menhaden fishery can participate by contacting Jean Ragg at Jean.Ragg@saiglobal.com.

LOUISIANA: Season opens early for bait fish to meet demand

March 6, 2017 — The Louisiana Wildlife and Fisheries Commission  announced a  Declaration of Emergency to open the commercial season for the harvest of bait menhaden starting Wednesday, March 15, 2017.

The actions on this declaration by the LWFC comes after request from the bait menhaden industry.

The commercial season for the harvest of bait menhaden typically opens on November 1 and runs through November 30 with a 3,000 metric ton quota. In the event that quota is not harvested during the normal November season, the bait season may resume April 1 of the following year.

Louisiana menhaden season to open March 15

March 3, 2017 — The commercial season for the harvest of bait menhaden will open March 15, the state Wildlife and Fisheries Commission decided today.

The season typically runs Nov. 1-20 with a 3,000-metric-ton quota. But when quota is not harvested during the normal season, the agency can reopen the fishery April 1 of the following year.

The bait industry asked the commission to open the season two weeks earlier to meet customer demand, officials said. The quota was not met in 2016, and opening the season two weeks earlier is not expected to negatively impact the quota or regular commercial menhaden season.

Latest report says menhaden thriving in the Gulf

October 25th, 2016 — A commission that assesses the health and viability of the menhaden population in the Gulf released a report this week that says despite massive commercial hauls, the menhaden population is sound.

It’s called a stock assessment for menhaden — a fish caught for catfood and fish oil supplements and a favorite food of large game fish. If fact, there’s been controversy this year over how many redfish commercial menhaden boats in the Gulf should be allowed to keep in the bycatch while fishing for menhaden.

Gulf States Marine Fisheries Commission evaluated the status of the Gulf menhaden in U.S. waters and concluded the “Gulf of Mexico’s menhaden stock is not experiencing overfishing,” said Steven J. VanderKooy, a fisheries coordinator with the commission, which has an Ocean Springs office.

The assessment was completed as a cooperative effort of Mississippi, Alabama, Florida, Louisiana, Texas and the National Oceanic and Atmospheric Administration.

Menhaden catches support the second largest commercial fishery by weight in the United States. Menhaden are small filter feeders that don’t grow much longer than a foot and only live for three or four years.

Despite the fact that millions of pounds are hauled in each year, they are thriving, VanderKooy said. “They are really, really resilient. It’s a great fish and short-lived.”

RONNIE SHELDON: Menhaden aren’t being ‘decimated’

August 16, 2016 — The following is an excerpt from a letter-to-the editor in the Mississippi Sun Herald.

Lately, I’ve read several opinion articles about the menhaden fishery and problems with Omega Protein.

I’m a lifelong resident of Pascagoula and a sport fisherman. I have no connections or interests in Omega Protein, but most of my spare time is spent fishing for trout and redfish, and I typically fish the same area (Round Island) where Omega Protein fishes for menhaden.

I have no issue with menhaden fishing. Their industry provides hundreds of jobs and pumps millions of dollars into our local economy. Indirectly, their product helps provide food for many as animal feed.

Their bycatch is closely regulated and very small. I’ve never personally seen evidence of any bycatch dumped overboard.

In his “Menhaden haven’t been ‘researched’” (July 31) letter, Steve Shepard’s statement that “menhaden are being decimated by boats during the hot summer months” doesn’t seem to be viable. The commercial menhaden fleet has been operating in our area for 60 years now. If Omega Protein were to decimate the menhaden fishery, they would put themselves out of a job, so it’s not probable.

KENNY HEBERT: CCA is telling fish tales about Omega Protein

April 20, 2016 — On April 2, the Sun Herald published an op-ed from the spokesman of the Coastal Conservation Association — Mississippi, F.J. Eicke (“A most important fish raises need for public scrutiny”), that was filled with more holes than a fisherman’s net. Sadly, time and time again, Mr. Eicke has demonstrated dismissiveness toward sustainable fisheries and the hardworking men and women of Mississippi’s commercial fishing industry.

A major contention offered by Mr. Eicke is that Mississippi’s resident menhaden stock is troubled. This statement is 100 percent incorrect and is little more than a scare tactic. There is no such thing as “Mississippi menhaden.” Due to their very nature — their biology and habitat — menhaden are a Coastwide migratory species, which is why menhaden stock assessments are conducted on a Coastwide basis.

As such, Mr. Eicke’s claim that the public “has no basis for assessing the catch in Mississippi waters” is nonsensical. Menhaden cross state borders routinely as they move around the Gulf. To assess the amount of menhaden in Mississippi waters at any given time is pointless, since, due to migratory patterns, the stock size would be completely different in subsequent days, weeks or months.

Contrary to Mr. Eicke’s claim that menhaden regulations are “minimal,” existing management has been successful in maintaining a sustainable fishery. According to the most recent, peer-reviewed Gulf States Marine Fisheries Commission stock assessment, the menhaden stock is healthy: It is neither overfished nor experiencing overfishing. The same results have been consistent going back 20 years.
