Fishermen who haul in greater amberjack may also get an unexpected $250 and an opportunity to contribute to the Greater Amberjack Count. The Gulf of Mexico greater amberjack recreational fishing season will reopen later this year pending a final decision by the Gulf of Mexico Fishery Management Council.聽聽聽聽聽聽聽聽聽聽聽

Dr. Sean Powers of the University of South Alabama is leading a 鈥淒ream Team鈥� of researchers in an $11.7 million study of the greater amberjack species. 亚洲色吧视频鈥檚 Marcus Drymon, an assistant extension professor at the university鈥檚 Coastal Research and Extension Center in Biloxi, is playing a key role in the project. Similar to the Great Red Snapper Count, the Greater Amberjack Count鈥檚 overarching goal is to estimate the number of greater amberjack in the U.S. South Atlantic and Gulf of Mexico, though additional objectives focus on understanding movement patterns and collecting biological information.聽聽聽聽聽聽聽聽聽聽聽

Funded by the National Sea Grant College Program and National Oceanic and Atmospheric Administration (NOAA) Fisheries, the project could have significant implications for commercial and recreational fishing and coastal economies supported by those industries.

According to NOAA Fisheries, greater amberjack in the U.S. Gulf of Mexico are overfished despite a decades-long rebuilding effort. In contrast, the U.S. South Atlantic stock is not overfished. Understanding how these two separately managed stocks are connected is vital for enacting proper management guidelines.

Recognizing a lack of biological and ecological information about greater amberjack, Congress appropriated $5 million to NOAA Fisheries and $5 million to Sea Grant for the amberjack study. Matching funds from institutions bring the total budget to $11.7 million. A team of 18 scientists from 13 institutions are working on the Greater Amberjack Count. In addition to 亚洲色吧视频, these include Auburn University, Texas A&M University, Louisiana State University and the University of South Florida. Also involved are Sea Grant programs from several states ranging from North Carolina to Texas.聽聽聽聽聽聽聽聽聽聽聽

The Greater Amberjack Count is well underway. Thus far, scientists have synthesized existing greater amberjack sightings and catch data from various fisheries datasets. This summer, they will begin a wide-scale tagging effort involving two different types of tags.聽聽聽聽聽聽聽聽聽聽聽

Some greater amberjack will be fitted with acoustic tags 鈥� electronic transmitters surgically implanted inside a fish鈥檚 body cavity. These tags emit signals unique to each fish, and the signals are recorded by an array of strategically placed underwater acoustic receivers or 鈥渓istening stations.鈥� A total of 450 acoustic tags 鈥� one per greater amberjack 鈥� will be deployed throughout the U.S. South Atlantic and Gulf of Mexico from North Carolina to Texas.聽聽聽聽聽聽聽聽聽聽聽

Many more greater amberjack will be fitted with conventional tags. These simple, plastic-coated objects are applied externally and resemble colorful streamers. They will be deployed across the same geographical range as the acoustic tags. Some greater amberjack will have one conventional tag, while others will have two (鈥渄ouble-tagged鈥�). This strategy will help scientists determine how often greater amberjack shed their conventional tags. A total of 750 greater amberjack will be tagged with conventional tags during this project. Notably, all acoustically-tagged greater amberjack will also be tagged with one or two conventional tags.聽聽聽聽聽聽聽聽聽聽聽

The conventional tags used for this project are designed for high visibility, with yellow coating at the base (closest to the fish鈥檚 body) and red coating at the end. One side of the tag contains the tag number (鈥淎J鈥� followed by five digits) and instructions to clip the tag for a $250 reward. The other side contains a phone number and reprinted tag number. The conventional tags will be placed on each fish鈥檚 back beneath its second dorsal fin. If a fish is double-tagged, there will be one tag on each side of the fish.聽聽聽聽聽聽聽聽聽聽聽

The success of the conventional tagging study critically depends on participation from fishermen of all sectors. Upon catching a conventionally-tagged greater amberjack, fishermen should call the phone number printed on the tag(s) to report the recapture to the Greater Amberjack Count project team. In addition to the tag number(s), fishermen will be asked to provide other information, including the fishing sector, date the fish was caught, fish鈥檚 length and weight, and latitude and longitude where the fish was caught. Each tagged greater amberjack, regardless if it has one or two tags, will carry a reward of $250.聽聽聽聽聽聽聽聽聽聽聽

Fishermen who catch a conventionally-tagged greater amberjack, and return the conventional tag(s) to the research team will receive a $250 reward. The physical tag must be mailed in to claim the reward, so fishermen should clip off and save the tag(s), even if they plan to release the fish. If a fish is double-tagged, fishermen will need to clip, report and return both tags to receive the reward.聽聽聽聽聽聽聽聽聽聽聽

The U.S. South Atlantic greater amberjack recreational fishing season is currently open. Although the U.S. Gulf of Mexico season is currently closed and set to reopen later this year, fishermen in the Gulf may incidentally catch conventionally-tagged greater amberjack while the season is closed. Even though these greater amberjack must be released, fishermen should still clip, report, and return the conventional tags. Some sublegal greater amberjack will be fitted with conventional tags; the same steps should be followed for these fish.聽聽聽聽聽聽聽聽聽聽聽

Data from the conventional tag returns and other components of the Greater Amberjack Count will ultimately be used by scientists to estimate the number of greater amberjack in the U.S. Gulf of Mexico.聽聽聽聽聽聽聽聽聽聽聽
