Unlike pelagic such as king fish, tuna and dolphin, grouper generally remain in one area except seasonal migrations into deeper or shallower water. Examples of likely grouper spots include rock formations, structure such as a wreck or sharp channel edge, rocky ledges with washouts and deepwater springs offering cover and a temperature change.

Clear water is a must for grouper, as mud irritates their gills and prompts them to move. By far, the best way to find good grouper bottom is through charts with the GPS and Loan coordinates.

In very clear water, with good sunlight and polarized glasses, you can often see the hard bottom structures. Sea turtles, especially big loggerheads, usually live around rocky bottom, so spotting one that has come up for air is a lucky break.

Search the area with your depth recorder and you’ll probably find a new grouper spot. Trolling large plugs such as Mirror, Mann’s Stretch 30, Rebel Jawbreakers and Magnum Rap alas on planers or down riggers will help you locate grouper concentrations.

On a strike, throw a marker buoy, return and search the spot with your bottom recorder. If you don’t immediately catch fish, drift near the buoy and search for peripheral structure.

Always save good spots in the memory of your GPS or Loan, as well as in a computer program if one’s available to you. Electronic memory is vulnerable to accidental erasure, so keep your data in multiple forms in two or three different places in case you lose one.

At faster speeds there is pressure on your down rigger cable creating blow back and raising your lures off the bottom. Diving planes with a big plug or large spoon attached to a rod and reel or heavy stainless cable work well because you can troll them faster and cover more ground.

Soft model wire on a rod and reel with a lead or diving plane gets down deep and it can be trolled at faster speeds. What Lures- Big diving plugs like the Mirror, Mann’s Stretch 30, Rebel and Papal work good.

Whether red, gag, black, yellow fin, or Warsaw, a good grouper in the ice chest means a successful day for lots of folks. Some species of grouper range from New England to southern Brazil and Texas.

They prefer to be able to seek shelter and hide, and although their name implies that they stay together, they can also be very solitary fish. Their coloration and ability to change hues and shades to identify with their surroundings give them that ambush capability.

Anglers find that medium heavy bottom fishing tackle is the best way to approach the grouper. Conventional reels in the thirty- to fifty-pound class teamed with a medium heavy boat rod will do the trick.

Grouper feed on other small fish, crustaceans like crabs or crawfish, and squid. When an easy opportunity swims buy they rush out, inhale their prey, and quickly return to their lair.

A good rod and reel, with fifty-pound test monofilament line, can handle almost all the grouper you may encounter. The terminal tackle consists of a sinker, leader, and hook arranged one of two ways.

Even when the rig is dropped right into the bottom structure, it seldom hangs up, something charter captains love. More serious grouper anglers will opt for the second approach, called a live bait rig.

Advertised as virtually invisible to fish, it does seem to draw more strikes than regular monofilament. Serious grouper anglers will crank the drag down on their reel as hard as they can, often using a pair of pliers to lock it down.

The idea is to stop the grouper from taking the line and returning to his structure home. When a grouper strikes, anglers will lay their rod on the rail and start winding as hard as they can.

When a grouper makes it into a rock or reef, many anglers will simply break off the line and try again. In the Gulf of Mexico, grouper anglers use magnum diving plugs that will go as deep as thirty feet or more.

The water in the Gulf of Mexico is comparatively shallow, and this method works well there. Strip baits are cut and attached to a double hooked trolling feather.

The wire line method is popular in and around south Florida in the winter when big black grouper move into the shallower reefs. Sometimes thirty yards in diameter, they are an ideal habitat for black grouper.

When one occurs, the boat moves directly away from the reef to drag the fish away from its hole. A head boat that provides the bait and tackle is an ideal way to bring some home to eat.

Grouper Malabar grouper, Epimetheus malarious Scientific classification Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Performed Family: Serranidae Subfamily: EpinephelinaeBleeker, 1874 Tribes and genera Not all errands are called 'groupers'; the family also includes the sea basses. The common name grouper is usually given to fish in one of two large genera : Epimetheus and Mycteroperca.

In addition, the species classified in the small genera Hyperion, Completes, Dermatologist, Graciela, Scotia, and Trio are also called 'groupers'. However, some hamlets (genus Affected), the hinds (genus Cephalopods), the lyre tails (genus Various) and some other small genera (Gonioplectrus, Nippon, Paranoia) are also in this subfamily, and occasional species in other serrated genera have common names involving the word grouper “.

Nonetheless, the word grouper on its own is usually taken as meaning the subfamily Epinephrine. Groupers are Telecasts, typically having a stout body and a large mouth.

They can be quite large, and lengths over a meter and the largest is the Atlantic Goliath grouper (Epimetheus Tamara) which has been weighed at 399 kilograms (880 pounds) and a length of 2.43 m (7 ft 11 1 2 in), though in such a large group, species vary considerably. They do not have many teeth on the edges of their jaws, but they have heavy crushing tooth plates inside the pharynx.

They habitually eat fish, octopuses, and crustaceans. Reports of fatal attacks on humans by the largest species, such as the giant grouper (Epimetheus lanceolatus) are unconfirmed.

They also use their mouths to dig into sand to form their shelters under big rocks, jetting it out through their gills. The word grouper is from the Portuguese name, group, which has been speculated to come from an indigenous South American language.

In New Zealand, “groper” refers to a type of wreck fish, Poly prion oxygenate, which goes by the Mori name haiku. In the Middle East, the fish is known as hammer ', and is widely eaten, especially in the Persian Gulf region.

The species in the tribes Grammistini and Diploprionini secrete a mucus like toxin in their skin called Rammstein and when they are confined in a restricted space and subjected to stress the mucus produces a foam which is toxic to nearby fish, these fishes are often called soap fishes. Jordan, 1923 Tribe Epinephrine Sleeker, 1874 Aethaloperca Fowler, 1904 Affected Bloch & Schneider, 1801 Anyperodon Gunther, 1859 Cephalopods Bloch & Schneider, 1801 Chromites Swanson, 1839 Dermatologist Gill, 1861 Epimetheus Bloch, 1793 Gonioplectrus Gill, 1862 Graciela Randall, 1964 Hyporthodus Gill, 1861 Mycteroperca Gill, 1862 Paranoia Guillemot, 1868 Plectropomus Pen, 1817 Scotia J.L.B.

Smith, 1964 Trio Randall, Johnson & Lowe, 1989 Various Swanson, 1839 Groupers are mostly monastic protogynous hermaphrodites, i.e. they mature only as females and have the ability to change sex after sexual maturity.

The largest males often control harems containing three to 15 females. As such, if a small female grouper were to change sex before it could control a harem as a male, its fitness would decrease.

If no male is available, the largest female that can increase fitness by changing sex will do so. Gonochorism, or a reproductive strategy with two distinct sexes, has evolved independently in groupers at least five times.

The evolution of gonochorism is linked to group spawning high amounts of habitat cover. Both group spawning and habitat cover increase the likelihood of a smaller male to reproduce in the presence of large males.

Fitness of male groupers in environments where competitive exclusion of smaller males is not possible is correlated with sperm production and thus testicle size. Gonochoristic groupers have larger testes than protogynous groupers (10% of body mass compared to 1% of body mass), indicating the evolution of gonochorism increased male grouper fitness in environments where large males were unable to competitively exclude small males from reproducing.

Many groupers are important food fish, and some of them are now farmed. Unlike most other fish species which are chilled or frozen, groupers are usually sold live in markets.

Groupers are commonly reported as a source of Ciguatera fish poisoning. DNA barcoding of grouper species might help in controlling Ciguatera fish poisoning since fish are easily identified, even from meal remnants, with molecular tools.

In September 2010, a Costa Rican newspaper reported a 2.3 m (7 ft 7 in) grouper in Cieneguita, Limón. The weight of the fish was 250 kg (550 lb) and it was lured using one kilogram of bait.
