U.S. wild-caught black grouper is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations. Fishing gears used to harvest black grouper have minimal impacts on habitat.

They also have teeth plates inside their throat that prevent prey from escaping after being swallowed. Black grouper take advantage of other species’ reproductive aggregations for feeding.

Black grouper are found in the western Atlantic from Massachusetts to Brazil. They are particularly associated with the southern Gulf of Mexico, Florida Keys, Cuba, the Bahamas, and throughout the Caribbean.

Annual catch limits are used for black grouper in the commercial and recreational fisheries. These fisheries are closed when their annual catch limit is projected to be met.

Both the commercial and recreational fisheries have size limits to reduce harvest of immature black grouper. The commercial and recreational fishing seasons are closed from January through April to protect black grouper during their peak spawning period.

To reduce by catch, there are restrictions on the type of gear fishermen may use and where they can fish. Year-round and/or seasonal area closures for commercial and recreational sectors to protect spawning groupers.

Groupers are managed separately by commercial and recreational sector in Puerto Rico. Seasonal closure for black, red, tiger, yellow fin, and yellow edge groupers from February 1 through April 30.

Similar Species: Gag, M. microbes (spur on properly is serrated); and yellow fin grouper, M. Vanessa (pectoral fins trimmed in bright yellow) Adults are associated with rocky bottoms, reef, and drop off walls in water over 60 feet deep.

They are protogynous hermaphrodites, meaning that young predominantly female who transform into males as they grow larger. Larger individuals of this species are generally found in greater depths, and they feed on fish and squid.

They prefer the rocky bottoms around reefs in the Western Atlantic, where they eat smaller fish and crustaceans, and grow to almost 52 inches long. The meat generates a fairly high price and is considered very good quality.

Ciguatera poisoning is caused by dinoflagellates (micro algae) found on dead corals or macro algae. By feeding on these corals and macro algae, herbivorous fishes accumulate a toxin generated by these dinoflagellates.

If accumulated levels of the toxin are great enough they can cause poisoning in humans whom consume the flesh of these fishes. Poisoned people report having gastrointestinal problems for up to several days, and a general weakness in their arms and legs.

Black grouper are fished both recreationally and commercially in waters around Florida, in particular the Gulf of Mexico. The IUCN is a global union of states, governmental agencies, and non-governmental organizations in a partnership that assesses the conservation status of species.

It is also present in the Gulf of Mexico and the Caribbean Sea, including the Florida Keys and Cuba. Juvenile black groupers are also found in seagrass beds off of the coast of Florida.

The preopercule is rounded without the presence of a notch, which distinguishes it from the gag grouper (Mycteroperca microbes). Black groupers are olive or gray with dark blotches and bronze spots.

These teeth are not used to tear flesh as with the barracudas and sharks, but rather to prevent small fish from escaping. Size, Age, and Growth Black groupers can reach up to 52 inches (133 cm) in length and can weigh up to 179 pounds (81 kg).

Food Habits Adult black grouper feed primarily on other smaller reef fishes, including grunts, snapper, and herrings. Since they will need to hide in the seagrass bed as well as tidal pool for protection until they are more mature.

They will also need to eat small microorganism inside the seawater such as micro algae, plankton, and even crustaceans. Then for adult grouper fish habitat, they will choose to live in the bottom area of the sea.

In their natural habitat they are able to find various fish that they feed on such as wrasse, parrot fish, snapper and dam selfish. Besides those fishes the adult grouper will also eat various other sea creatures such as crustaceans, octopus, lobster, and crab.

When it comes to their habitat, the grouper fish will stay in the same place for a long time. They will lie hidden in a place where they will wait, so they can ambush their prey that comes near into their hiding spot since their jaws are fast and powerful to do this method.

This grouper fish has form a habit to follow down an ell when they go foraging in the reef. Besides hiding, turns out grouper fish also have unique ability that allows them to change their body coloration which will give them a lot of advantage.

Another unique thing that also happens inside the grouper fish habitat is when their reproduction period arrive which usually in the full moon of winter season. However, during their reproduction period, then they will form very large school which may even consist of 100,000 grouper fish at once.

The reason why they gather in large number like this is because they want to increase the probability for their mating to be successful. Furthermore, when large amount of grouper fish spawn in the same time, then they will also have higher chance for survive.

This grouper fish is also able to control the population of other sea creature inside their habitat so it would not overpopulate the area where they live in. This is why; it is important to maintain the grouper fish population in that area and also to protect their habitat so there is no bad thing happens that can damage the entire ecosystem.

The closer food is to the right edge of the map, the more essential nutrients per calorie it contains. For a more nutritious diet, select foods that fall on the right half of the map.

How to interpret the values: Experts vary on their recommendations for what your total glycemic load should be each day. A typical target for total Estimated Glycemic Load is 100 or less per day.

NUTRIENT BALANCENutrient Balance Indicator for Fish, grouper, mixed species, raw The spoke for dietary fiber is colored green, protein is blue, vitamins are purple, minerals are white, and yellow represents a group of commonly over consumed nutrients: saturated fat, cholesterol, and sodium.

PROTEIN QUALITYProtein Quality for Fish, grouper, mixed species, raw If one or more amino acid is not present in sufficient amounts, the protein in your diet is considered incomplete.

Each spoke on the Protein Quality graph represents one of the nine essential amino acids, and the graph shows how close the protein in your diet is to the optimal distribution of amino acids recommended by the Institute of Medicine's Food and Nutrition Board. An Amino Acid Score of 100 or higher indicates a complete or high-quality protein.

Foods that are both nutritious and filling are considered better choices for weight loss. Foods that are nutritious without being filling are considered better choices for healthy weight gain.
