Parasite are animals that lives on or in another organism, the host, causing it some harm. However, for a biologist, parasites are fascinating and often represent the most interesting cases of evolution.

In addition, parasites may well constitute the majority of life on earth, both in the number of species and individual animals. We chose to study the parasites of emblematic fishes, the groupers.

Attaching themselves firmly to soft tissue requires a special organ, the raptor, which contains sharp hooks that penetrate the gill's surface. The name “monogenean” was given by Belgian parasitologist Pierre-Joseph Van Bender more than a century ago, and means that their life cycle involves only a single host fish.

Studies in recent decades revealed that most monogeneans on the gills of groupers belonged to a single, hyper-diverse group. This is how evolution works, and having a different sexual morphology prevents incompatible species from copulating with each another, therefore avoiding wasting energy in mating that would not produce progeny.

All its species are hermaphrodite, so for each individual there are two complete sets of sexual organs, one male and one female. All Pseudorhabdosynochus species have a male ovulatory organ that is a highly specialized pump that inserts sperm into the female genitalia.

Previous results had shown that the groupers in warm sea, including coral reefs, harbored a rich fauna of parasites, especially monogeneans on fish gills. However, a single big grouper can harbor hundreds of monogeneans, so a few fish provide ample work for the passionate parasitologist (and, occasionally, opportunities for nice meals).

To our surprise, it was identical to Pseudorhabdosynochus sulamericanus, a species from the western Atlantic. The surprising distribution of Pseudorhabdosynochus sulamericanus (asterisks), found both along the American coasts and in the Mediterranean.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. Out of the hundreds of fish I've caught I've seen some weird stuff but it seems like about 1 in 8 red grouper I catch has worms.

Some people say you can cook them inside the fillet and eat them but that's just not going to happen to me. Not harmful, but they look nasty and you kinda lose your appetite for fish.

Just gotta look past the worms when you eat the fish. The last red grouper I caught had ones the size of a maggot and about 15 of them all throughout the meat.

Can't pay me to eat one, just sucks throwing out a nice grouper. Iv seen worms in reds for years pretty tasty little things when u fry them they taste just like fish.

But do you know why they prefer red grouper and sea trout? I've found lots of worms in amber jack and Yahoo, just to name two species.

Can't pay me to eat one, just sucks throwing out a nice grouper. They won't hurt you and you can pull em out easy enough.

They are easily removed if you are going to broil or bake the fish and you worried about someone a little squeamish eating it. If the meat is cooked it is just extra protein.

But then again I have eaten (and enjoyed) sushi, raw oysters, raw clams, rare beef, and an occasional ant, grub, or grasshopper. Parasites are worse in a fish with a weakened immune system.

Attaching themselves firmly to soft tissue requires a special organ, the raptor, which contains sharp hooks that penetrate the gill’s surface. The name “monogenean” was given by Belgian parasitologist Pierre-Joseph Van Bender more than a century ago, and means that their life cycle involves only a single host fish.

Studies in recent decades revealed that most monogeneans on the gills of groupers belonged to a single, hyper-diverse group. This is how evolution works, and having a different sexual morphology prevents incompatible species from copulating with each another, therefore avoiding wasting energy in mating that would not produce progeny.

Left: whole body; right: hard parts. Chaabane & Justine In this aspect Pseudorhabdosynochus is certainly not disappointing, and for three reasons: All its species are hermaphrodite, so for each individual there are two complete sets of sexual organs, one male and one female.

Previous results had shown that the groupers in warm sea, including coral reefs, harbored a rich fauna of parasites, especially monogeneans on fish gills. However, a single big grouper can harbor hundreds of monogeneans, so a few fish provide ample work for the passionate parasitologist (and, occasionally, opportunities for nice meals).

When groupers are reared in a small pond of seawater, monogeneans can proliferate exponentially and species of Pseudorhabdosynochus are a well-known cause of death. This article is published in collaboration with researchers from Islet (Institute de Systématique, Evolution, Biodiversity, Museum national d’History naturally, Sorbonne Universities).

Every month they propose a scientific chronicle of biodiversity: “En direct DES species”. Objective: to understand the interest of describing new species and cataloging living things.

Grouper are often targeted because their flesh has an amazing texture and consistency that people love on sandwiches, blackened on a plate, or in a salad. If you haven’t had a grouper sandwich, you’re missing one of life’s true pleasures.

Only three species cannot be caught and eaten, you can see in the black cells in the chart below. And stay at the bottom (3 to 230 feet deep) eating crustaceans and smaller fish.

Coney Grouper have color variations including hues of red, brown, and yellow. Body with many small blue spots unless in bright yellow phase coloration.

Identification isn’t difficult when the Goliath Grouper is mature at 400 to 800 lbs. Goliath Grouper Identifying Features Can grow to 8 feet in length and over 800 lbs.

Grays by Groupers are best identified with series of spots below dorsal fin. Operate with 3 flat spines (by anus) 4 dark or white spots at base of dorsal fin.

Strict regulations are in place to attempt to bring back a healthy Florida population of these fish. This grouper eats fish, crabs, and squid and can grow to around 5 feet in length and over 200 lbs.

Misty Grouper Identifying Features Easily recognizable by 8-11 dark bands, similar to Sleepyhead fish. These Red Grouper spawn more than twenty times between February and June each year.

Lives on rocky reefs and feeds on crabs mostly and fish secondarily. Rock Hind Grouper Identifying Features Coloration varies, but overall tan color with large oval/circular spots of reddish brown, red, and dark gray and black that get larger toward the ventral side (belly).

Scamp grouper have almost decorative fins, which can make them easy to identify. Scamp Grouper Identifying Features Scamp Grouper have a brown or reddish body, sometimes it is light gray Lateral (sides) are covered with dark spots, sometimes in small groups.

Upper and lower caudal fin rays are long in a spot, giving appearance of an oriental style fish. Tail is also unique with top and bottom having lengthy spines.

Sub-adults are dark brown and have white spots in vertical rows on head and body. Speckled Hind Grouper Identifying Features Adults (15 inches +) are dark reddish brown and covered all over by small bright white spots.

Yellow mouth Grouper Identifying Features Inside of mouth is yellow. IUCN Realist Status: The Goliath Grouper is listed as Vulnerable and populations declining.

Other Grouper species in Florida State waters are plentiful and not in danger of being overfished. Appearance: Grouper have a thicker body than some other fish with respect to length.

Some Grouper are found in the Caribbean, Cuba, Portugal, Trinidad, Brazil, and the West Indies. Young grouper spend their early years near submerged rocks and other structure close to the beach, so they don’t become prey for Shook, Jacks, Redfish, other Grouper, Tarpon, and Sharks.

Diet: Pinkish, mullet, other bait fish, crabs, squid, octopus, lobster. This section was easy to write because all three grouper world records were caught in Florida, so they’re the same.

The Biggest Goliath Grouper was caught on hook and line in 1961 at Fernanda Beach, Florida. I remember talking to some people who’d seen a massive Goliath Grouper at the Sunshine Skyway Bridge that they named Hitler.

The Biggest Red Grouper was 42 pounds, 4 ounce fish that was caught on hook and line off St. Augustine, in the Atlantic side of Florida in 1997. Grouper is one of the most often targeted species of fish by anglers all over the USA for a couple of reasons.

If you’ve never had a blackened grouper sandwich at a restaurant along the coast in Florida, you’re missing an incredible experience. Grouper is thick and juicy and has an odd texture that most fish don’t possess.

Besides being great for a meal, Grouper takes your bait and immediately pulls hard when it realizes it is attached to your line. It’s a real fight to get a grouper up off the bottom of the sea, especially if it’s down 100 feet or more.

They’re heavy, strong, and tough fighting fish that will give you a workout. Small grouper can be found generally inshore, and in water 15 feet deep or more usually.

I’ve caught small black, red, and gag grouper in shallow areas near the Sunshine Skyway Bridge in south Pinellas County. To find adult grouper you’ll need to take a charter off the coast and ride out for a while to reach deeper water.

Around 60 feet deep is a good starting point, and any structure, wrecks, or rocks will probably hold at least a grouper or two, but bigger areas will hold dozens, possibly hundreds. Don’t get me wrong, you CAN find grouper in shallower water when it’s cooler, and I’ve seen them pull 12 lb.

Gag Grouper out of 10 feet of water off the Gulf Coast. You basically drop your pinkish down to the bottom and hold on for dear life.

It doesn’t really matter how much weight you used to get your bait down there, you’ll certainly feel it when the Grouper inhales your bait fish! If you’re fishing with artificial, you can get some larger Your Minnows with 2 treble hooks and try those retrieved at a fast (but not blinding) rate.

Hit the piers, wrecks, rocks, and fallen trees to try to find some Grouper in the shallows if you are in a Kayak fishing or other small boat. Every year there are some good size Grouper pulled in at most of the big piers in Florida.

Between Thanksgiving and Christmas is prime time for Grouper in Florida. Big Grouper bait casting reels and strong rods are essential if targeting fish over 50 lbs.

Bait casting / Trolling Reels This PENN REEL (at Amazon) for Inshore Fishing (Grouper, Redfish, Cobra) Made in America (Philadelphia, PA.) Of course if you get in the middle of huge fish, you should increase the size of your hook.

The easiest way to set up a Grouper Rig is to use a simple egg sinker, swivel, and leader on the end of your braided line. Mono with an 8/0 Circle Hook holding live bait like a Pinkish, Pilchard, or other similarly sized fish.

You don’t set a circle hook, you’ll likely just pull it free of the mouth before it has a chance to work itself into the jaw of the fish. You can Troll for Grouper in the Gulf, and that works well for people who feel like they have to be on the move and want to fish shallow water.

Hook and line, and spearfishing are legal options for harvesting most Grouper Species. Grouper species are regulated differently, and it’s quite daunting to try to comb through the official website and figure out what you can and can’t catch, when and where.

We’ve combined all Grouper Laws into this graphic to make it easier, but to be honest, it’s a bit easier, but you still need to read a lot to understand how to take Grouper legally in Florida and in International Waters. If you also want to know about which fishing license and permits you need in Florida, we just created a new page for that HERE which easily explains it.

Grouper are farm raised in some areas of the world, primarily Asia. Here’s an interesting and informative article about some challenges Grouper farmers faced in Thailand.

The best way to cook Grouper is to blacken it with some Cajun spices or something that adds some spiciness or other flavor to it. I always bleed the grouper immediately after catching by cutting the gills with scissors or a knife after I’ve put him out of his misery.

Trying to bleed a fish after icing, is an exercise in futility as not all the blood comes out easily. I also coat each side in some finely ground black pepper because I love the taste.

Put the Grouper Fillets in the pan and cover, leaving room for the steam to gather, and escape. Cut your Italian bread into sandwich-sized portions and smear butter and minced garlic pieces on them.

Put in oven on top shelf on Broil until lightly brown, remove quickly. Even thick Grouper should cook through in 3-4 minutes per side.

As telecasts, all types of grouper have a stout body and a large mouth and are weak swimmers. However, once caught, a grouper will put up a vicious fight and use their vast bulk to full advantage.

If you are casting in the shallows, use jerk bait and retrieve it erratically to lure the fish out in the open. You will need heavy tackle, especially if there are a lot of rocks under the water where you are fishing and a braided line that can withstand the powerful pull of a caught grouper.

If you are using spinning tackle, make sure that the reel is heavy enough to withstand an 80 to 100-pound test mainline and a low gear ratio to give you more control. This tackle will come in handy when the panicking grouper fish tries to swim under a ledge to break the line.

For live bait, use pinkish, grunts, blue runner, sardines, and mullet. The grouper is a lean and moist fish that has a mild flavor, and the flesh is firm and flaky.

Among the species most popularly sought after by fishing enthusiasts is the gag grouper, a bottom feeder with less distinguished color markings than its cousins. All groupers put up quite a fight when hooked, making them a favorite among anglers of all ages and experience levels.

They prefer waters in the 50-75 foot depth range, although the younger juveniles spend time closer to the shore. Most often, large harems of this grouper variety swim near the sea floor underneath outcroppings of rock, below stands of coral, and around sunken vessels.

Unlike other members of the grouper family, the gag does not develop yellow lines around the mouth, nor does it grow streamer points at the end of the tail fin. Like all groupers, the gag variety reproduces only females, with a few of the largest adults undergoing a sex change brought on by behavioral triggers.

Dropping in a heavier line straight to the bottom with a live bait hook is the preferred method of attracting this species. Experienced anglers usually prefer heavier equipment, especially if bottom fishing in waters exceeding a depth of 60 feet.

Using a lighter line or softer drag often results in the fish escaping to a nearby hole or underneath an outcropping. Both fish have similar habitats, and most experienced fishermen suggest using the same bait for groupers that has been proven reliable for snappers and other locally found bottom feeders.

Nearly every fishing tour company in the Key West area will book day trips for those wanting to catch gags and other groupers.
