Grouper fish are some of the most fascinating creatures that inhabit our oceans. These large, powerful fish are known for their impressive size and strength, making them a popular catch among anglers and a favorite dish for seafood lovers. But just how big do these fish get? In this blog, we’ll dive into the world of grouper fish and explore their impressive size and growth patterns. From the massive Goliath grouper to the colorful and agile rock hind, we’ll take a closer look at the incredible variety of grouper species and uncover the secrets behind their impressive size and longevity. So if you’re curious about these impressive fish and want to learn more about their incredible size and growth patterns, then read on!
What is the Largest Species of Grouper
The grouper is part of a large family of fish called Serranidae.
It takes effort to determine how large they can grow and which grouper species are the largest, as there are more than 30 species.
I saved you time by researching and found that the Atlantic goliath grouper is the largest type of grouper.
Because I could not include all grouper species with their different sizes in this article, it would take too much space. We’ll be focusing on the goliath grouper.
What Is the Maximum Size of Groupers?
Atlantic goliath groupers may reach up to 8 feet in length and 800 pounds in weight. The majority of fish will not exceed 400 pounds.
They are often called the ocean’s gentle giants because of their size and the way they approach divers with extreme calmness and caution.
They are giants! However, if they are hooked up with a rod or reel, they will not be as gentle.
These giants are well-known for being one of the most intelligent and hardy fighting game fish in the world. A grouper of more than 100 pounds is the ultimate catch (if it can be gotten into the boat).
It’s hard to imagine how it must feel to be surrounded by a 500+ pound goliath grouper.
Unfortunately, this species, which is the home of the Southwestern Atlantic fish, has been overexploited for many years and is slowly recovering.
The Florida Fish and Wildlife Conservation Commission and other authorities still consider it an endangered species. However, the FWC has authorized a restricted recreational harvest of goliath groupers to be taken in state waters by 2022. That’s a great sign!
Who knows what giant grouper may be lurking in the Atlantic ocean’s deepest depths? It is possible to find a 1000-pound fish out there!
What is the Average Size of Groupers
The sizes of goliath groupers caught by hook and line are very different. Their average weight ranges between 50 and 200lb, according to all records.
This type of grouper is rare among sport anglers so let’s take a look at some other species that are commonly fished for and caught and their average sizes.
Type of Grouper Average Size
- Warsaw Grouper, 30-80 lb
- Snowy Grouper, 20-40 lb
- Black Grouper, 10-25 lb
- Yellowfin Grouper, 10-20 lb
- Gag Grouper, 5-20 lb
- Red Grouper, 5-10 lb
- Scamp Grouper, 2-5 lb
You can expect decent-sized fish regardless of which grouper you are after.
You’ll often find yourself hauling in a trophy grouper more often than you think!
What Is the Largest Grouper Ever Caught?
The all-tackle record for the Atlantic goliath grouper, which is the largest grouper in the family, is naturally held by this species.
A 680 lb monster fish is the largest ever hooked and caught grouper. Since then, many 400- and 500-pounders have been captured, but no one has ever been able to break that record.
It’s possible to be the lucky one to catch a 700 lb goliath grouper, but they’re still out there!
What Is the Smallest Type of Grouper?
The coney grouper (Cephalopholis.fulva) is one of the smallest known groupers, with a maximum size of around 10 to 12 inches.
Ten inches is dwarf-like when compared to the coney’s monstrous relatives, the warsaw grouper and the goliath grouper.
Even though the coney grouper may be a subspecies within the larger grouper family, it is still a grouper.
This grouper species can be found at depths up to 200 feet in coral reefs.
It is found in the Atlantic Ocean’s Western part, from South Carolina to the Gulf of Mexico, and the Florida Keys off South Florida.
How Fast Do Groupers Grow?
Groupers, despite being a large species of fish, have a slow growth rate once they reach the adulthood stage.
However, young goliath groupers grow very quickly until they reach the age of five to six years. They will average 6 inches in height per year. Their growth rate will be much slower once they reach adulthood, which is around five years old.
Their average annual growth rate between ages 5 and 15 is just 1.2 inches. After they turn 25, the rate of growth slows to less than 0.4% per year. The goliath grouper’s 8-foot (96 inch) length means they must be very old.
What Age Do Groupers Get?
The smaller grouper species (scamp, yellowfin and red) live an average of 10 to 15 years and can reach their maximum age of 25-30 years. However, larger groupers can live longer.
The average life expectancy for big groupers like black and warsaw groupers is 20-30 years. They can live up to 50 years.
The Snowy grouper stands out because a research team found a specimen in the 1990s that was around 54 years old. This makes it the oldest member of the larger grouper family.
