“Bluefish!” … “It’s just a school of bluefish!” So yelled the lifeguard in Jaws II when Chief Brody had mistaken a school of bluefish for the rogue great white shark that was plaguing the town. He would not have been the first to mistake these large schools for a larger fish, particularly a predatory shark, but as some know, bluefish are quite predatory themselves.

Growing up along the Florida panhandle we heard little about this species. We had heard stories of large bluefish schooling along the Atlantic coast killing prey with their razor-sharp teeth and, at times, biting humans. But not much was mentioned about them swimming along our shores. But they do, and I have caught some.
Bluefish are one of several in a group Hoese and Moore refer to as “mackerel-like fish” in Fishes of the Gulf of Mexico. They differ in that they lack the finlets found along the dorsal and ventral sides of the mackerel body and mackerels lack scales having a smoother skin. Bluefish are the only members of the family Pomatomidae. They can reach three feet in length and up to 30 pounds. They travel in large schools viciously feeding on just about anything they can catch and seem to really like menhaden. They move inshore for feeding and protection from larger ocean predators but do move offshore for breeding.
Bluefish landed from the Gulf of Mexico are much smaller than their Atlantic cousins, rarely weighing in more than three pounds. They do have a deep blue-green color to them and thin caudal peduncle and forked tail giving them the resemblance of a mackerel or jack. Some say they are bit too oily to eat while others enjoy them quite a bit. There is a commercial fishery for them in Florida and, as you would expect, it is a larger fishery along the east coast. Most of the panhandle counties have had commercial landings, albeit small ones.
Biogeographically, the blue fish are found all along the Atlantic seaboard and into the Gulf of Mexico. It is listed as worldwide but seems to be absent from the Caribbean and other tropical seas. This could be due to a distaste of warmer waters, or the lack of their prey targets.
They are an interesting and less known fish in our region. Swimming in a school of them should be done with caution, there are reports of nips and bites from these voracious predators.

I am going to be honest and say that I know very little about this fish. I did not know they even existed until I attended college. Shortly afterwards, my father-in-law asked “hey, have you ever heard of a tilefish?” – to which I responded yes… He was having lunch at a restaurant in Apalachicola, and it was on the menu. My father-in-law was an avid fisherman and knew most of the edible species, but he had not heard of this one. The rumor was that it was pretty good, though my father-in-law chose not to eat it that day.

I have never seen it on a menu, and only a few times in the local seafood markets, but according to Hoese and Moore1 by the late 1970s there was a small commercial fishery for this fish emerging in Louisiana, as was a small recreational fishery. In Florida, since 2000, there have been 15,435 commercial trips for this fish with an average of 321 each year. The value of this fishery over that time is $33,118,554 with an average of $689,969.90 each year. The average price for the fishermen was $2.62 per pound with the highest being $5.14/lb. on the east coast and that in 2022; the Gulf fishermen are getting $4.16/lb. right now.
The highest number of landings per county since 2000 was 340 in Palm Beach County in 2000. Only eight times has there been more than 200 landings in a single year over the last 22 years. Five of those were in Monroe County (Florida Keys) and three were again in Palm Beach County. The vast majority were less than 100 landings in a single year, this is not a large fishery in Florida either.
Are they harvested here in the Florida panhandle?
Yes… Bay, Escambia, Franklin, Okaloosa, Wakulla, and Gulf Counties all reported landings. Bay County seems to be the hot spot for panhandle with landings between 50-100 each year since 2000. Most of the other counties report less than 10 a year and several only reported one. Again, this is not a large fishery, but it was sold at a restaurant in Apalachicola and is said to be good. Hence, I decided to include in this series.
Hoese and Moore report four species of tilefish in the Gulf of Mexico. The sand tilefish (Malacanthus plumeri) is a more tropical species. The tilefish (Lopholatilus cheamaeleonticeps) and the gray tilefish (Caulalatilus microps) seem to be the target ones for fishermen. Both are reported from deep cold water near the edge of the continental shelf. FWC reports them from 250 – 1500 feet of water where the temperatures are between 50 – 60°F. Because of their tolerance to cold water, their geographic range is quite large; extending across the Gulf, up the east coast to Labrador. They live in burrows on hard sandy bottoms and feed on crustaceans. The National Oceanic and Atmospheric Administration2 reports this as a slow growing – long lived fish, up to 50 years of age. In their cold environment, this makes sense.
This is not a well-known fish along the Florida Panhandle but maybe one day you will see it on the menu, remember this article, and take a chance to see if you like it.

There are several considerations to be taken in fishpond management. During the first of a three-part webinar series, Dr. Laura Tiu and Daniel Leonard talk about how to manage your pond to optimize its health.
Considerations on liming your pond, fertilizing your aquatic vegetation and how to manage dissolved oxygen are topics address in this recording.
The webinar in its entirety can be viewed at: Fish Camp: Pond Health
One of the recommended methods of tracking the health of your pond is enjoyable! As a pond manager you should be gathering simple information about the fish you catch. By tracking the fish that you catch, you can look at presence, size distribution and relative abundance of adult fish populations, which is directly linked to the health of your body of water.
When logging your catch, the following should be considered:
- Date – You will want to evaluate the catches from the same time of year over several years
- Weight- not only is the length of the fish important but also collect the weight
- Type/Species of each fish caught and approximate maturity of that fish
By logging your catches over the years, you will begin to see trends and have more information to make pond management decisions. More helpful information can be found at:

How to Assess the Fish in Your Farm Pond

Spring can be a busy time of year for those of us who are interested in improving wildlife habitat on the property we own/manage. Spring is when we start many efforts that will pay-off in the fall. If you are a weekend warrior land manager like me there is always more to do than there are available Saturdays to get it done. The following comments are simple reminders about some habitat management activities that should be moving to the top of your to-do list this time of year.
Aquatic Weed Management – If you had problematic weeds in you pond last summer, chances are you will have them again this summer. NOW (spring) is the time to start controlling aquatic weeds. The later into the summer you wait the worse the weeds will get and the more difficult they will be to control. The risk of a fish-kill associated with aquatic weed control also increases as water temperatures and the total biomass of the weeds go up. Springtime is “Just Right” for Using Aquatic Herbicides
Cogongrass Control – Spring is actually the second-best time of year to treat cogongrass, fall (late September until first frost) is the BEST time. That said, ideally cogongrass will be treated with herbicide every six months, making spring and fall important. When treating spring regrowth make sure that there are green leaves at least one foot long before spraying. Spring is also an excellent time of year to identify cogongrass patches – the cottony, white blooms are easy to spot.

Warm-Season Food Pots – There is a great deal of variation in when warm season food plots can be planted. Assuming warm-season plots will be panted in the same areas as cool-season plots, the simplest timing strategy is to simply wait for the cool-season plots to play out (a warm, dry May is normally the end of even the best cool-season plot) and then begin preparation for the warm-season plots. This transition period is the best time to deal with soil pH issues (get a soil test) and control weeds. Seed for many varieties of warm-season legumes (which should be the bulk of your plantings) can be somewhat hard to find, so start looking now. If you start early you can find what you want, and not just take whatever the feed store has. Warm Season Food Plots for White-tailed Deer
Deer Feeders – Per FWC regulations deer feeders need to be in continual operation for at least six months prior to hunting over them. Archery season in the Panhandle will start in mid-October, meaning deer feeders need to be up and running by mid-April to be legal to hunt opening morning. If you have plans to move or add feeders to your property, you’d better get to it pretty soon. FWC Feeding Game
Dove Fields – The first phase of dove season will begin in late September. When you look at the “days to maturity” for the various crops in the chart below you might feel like you’ve got plenty of time. While that may be true, don’t forget that not only do you need time for the crop to mature, but also for seeds to begin to drop and birds to find them all before the first phase begins. Because doves are particularly fond of feeding on clean ground, controlling weeds is a worthwhile endeavor. If you are planting on “new ground”, applying a non-selective herbicide several weeks before you begin tillage is an important first step to a clean field, but it adds more time to the process. As mentioned above, it’s always pertinent to start sourcing seed well in advance of your desired planting date. Timing is Crucial for Successful Dove Fields
There are many other projects that may be more time sensitive than the ones listed above. These were just a few that have snuck up on me over the years. The links in each section will provide more detailed information on the topics. If you have questions about anything addressed in the article feel free to contact me or your county’s UF/IFAS Extension Natural Resource Agent.

Cobia Researchers use Transmitters as well as Tags to Gather Data on Migratory Patterns
I must admit to having very limited personal experience with Cobia, having caught one sub-legal fish to-date. However, that does not diminish my fascination with the fish, particularly since I ran across a 2019 report from the Gulf States Marine Fisheries Commission titled “Management Profile for Gulf of Mexico Cobia.” This 182-page report is definitely not a quick read and I have thus far only scratched the surface by digging into a few chapters that caught my interest. Nevertheless, it is so full of detailed life history, biology and everything else “Cobia” that it is definitely worth a look. This posting will highlight some of the fascinating aspects of Cobia and why the species is so highly prized by so many people.
Cobia (Rachycentron canadum) are the sole species in the fish family Rachycentridae. They occur worldwide in most tropical and subtropical oceans but in Florida waters, we actually have two different groups. The Atlantic stock ranges along the Eastern U.S. from Florida to New York and the Gulf stock ranges From Florida to Texas. The Florida Keys appear to be a mixing zone of sorts where Cobia from both stocks go in the winter. As waters warm in the spring, these fish head northward up the Atlantic and Gulf coasts of Florida. The Northern Gulf coast is especially important as a spawning ground for the Gulf stock. There may even be some sub-populations within the Gulf stock, as tagged fish from the Texas coast were rarely caught going eastward. There also appears to be a group that overwinters in the offshore waters of the Northern Gulf, not making the annual trip to the Keys. My brief summary here regarding seasonal movement is most assuredly an over-simplification and scientists agree more recapture data is needed to understand various Cobia stock movements and boundaries.
Worldwide, the practice of Cobia aquaculture has exploded since the early 2000’s, with China taking the lead on production. Most operations complete their grow-out to market size in ponds or pens in nearshore waters. Due to their incredible growth rate, Cobia are an exceptional candidate for aquaculture. In the wild, fish can reach weights of 17 pounds and lengths of 23 inches in their first year. Aquaculture-raised fish tend to be shorter but heavier, comparatively. The U.S. is currently exploring rules for offshore aquaculture practices and cobia is a prime candidate for establishing this industry domestically.
Spawning takes place in the Northern Gulf from April through September. Male Cobia will reach sexual maturity at an amazing 1-2 years and females within 2-3 years. At maturity, they are able to spawn every 4-6 days throughout the spawning season. This prolific nature supports an average annual commercial harvest in the Gulf and East Florida of around 160,000 pounds. This is dwarfed by the recreational fishery, with 500,000 to 1,000,000 pounds harvested annually from the same region.
One of the Cobia’s unique features is that they are strongly attracted to structure, even if it is mobile. They are known to shadow large rays, sharks, whales, tarpon, and even sea turtles. This habit also makes them vulnerable to being caught around human-made FADs (Fish Aggregating Devices). Most large Cobia tournaments have banned the use of FADs during their events to recapture a more sporting aspect of Cobia fishing.
To wrap this up I’ll briefly recount an exciting, non-fish-catching, Cobia experience. My son and I were in about 35 feet of water off the Wakulla County coastline fishing near an old wreck. Nothing much was happening when I noticed a short fin breaking the water briefly, about 20 yards behind a bobber we had cast out with a dead pinfish under it. I had not seen this before and was unaware of what was about to happen. When the fish ate that bait and came tight on the line the rod luckily hung up on something in the bottom of the boat. As the reel’s drag system screamed, a Cobia that I gauged to be 4-5 feet long jumped clear out of the water about 40 yards from us. Needless to say, by the time we gained control of the rod it was too late; a heartbreaking missed opportunity. Every time we have been fishing since then, I just can’t stop looking for that short, pointed fin slicing towards one of our baits.
