This week we are going to cover a group of iconic fish in both inshore and offshore waters of the SE United States. So what exactly is a snapper? Snapper are fish that belong in the family Lutjanidae, and are characterized by primarily nocturnal, predatory fish that associated with coral reef, rock, concrete, oyster, and mangrove structures in their environment. Generally during the day they hide around their structure and in the evenings they actively ambush smaller fish in the open waters around the structure. The body style of snapper can vary somewhat but they all have notoriously strong mouths full of very sharp teeth and are known to actively snap their jaws shut repeatedly when out of the water as a defense mechanism. Most of snapper identification is achieved by looking at body shape and body and fin colors and patterns which may change somewhat from juveniles to adults.

I need to clear up one misconception before we get started. There are some fish that are called snappers that aren’t really snappers and will be excluded from my list. The most common example is the hogfish snapper, or hogfish. Despite their similarities in body shape and teeth, these fish are actually a wrasse, a totally different group of fish. Some fisherman also lump grunts in the same family as snapper. Despite similarities, grunts are also an entirely different family of fish (thankfully because there sure is a lot of them).

I’m going to go over the 13 species of snapper an inshore and offshore angler would want to know as they all have different regulations relating to minimum sizes, closed seasons, and bag limits. I did exclude one snapper on this list, the wenchman snapper. I did this because it’s only common in gulf and in very deep water, but please note that this is a potential species of snapper that could be caught as well. Please see the diagrams and photos below where I denoted whether they commonly occur offshore or inshore, or both.

Here’s the list of snappers we will cover:

  • American Red Snapper
  • Silk Snapper (aka Yelloweye Snapper)
  • Blackfin Snapper
  • Vermillion Snapper (aka Beeliner Snapper)
  • Yellowtail Snapper
  • Queen Snapper

I want to briefly discuss the American red snapper regulation problem since we are on the topic. Please note my intent of including this is not to change people’s minds and forcibly inject my ideas upon everyone else, but rather I would like to stimulate thought on the issue and help others think about problems from a different perspective.

A little background incase you are unfamiliar: the red snapper population decreased dramatically in past several decades mostly due to the increase in BOTH the commercial fishing effort for them as well as the huge increase in recreational effort on both of Florida’s coasts. Strict federal regulations with closed seasons were placed on the species; rarely opening up for only a couple days at a time each year on good years.

A lot of recreational fisherman in the Atlantic complain that the regulations are still far too strict there, yet the gulf gets much more relaxed open seasons. Fisherman in the Jacksonville – Port Canaveral area are especially vocal because red snapper is a common catch for many people in these areas, and on some reefs that is all people catch.
Jokes circulate about catching the ‘endangered red snapper’ but the reality is that the population AS A WHOLE remains a fraction of its historical numbers.

Please consider some facts about the American red snapper:

  1. Red snapper are not evenly distributed along the coasts. The Jacksonville area has a large amount of hard bottom reefs that extends over 70 miles off the coast in relatively shallow (less than 300ft). This is perfect red snapper habitat and there is a lot of it. The bulk of the population is in these waters. Compared to south Florida where the perfect red snapper habitat may end only 10 miles (or less) off the coast, there is significantly less individuals in those areas.
  2. The gulf has significantly different hard bottom habitats than the Atlantic and a drastically different bottom topography. Not surprisingly this means a different concentration of snapper.
  3. The gulf also has less people than the Atlantic. Less people means less fisherman which means less fish being caught, hence different regulations.
  4. Like all snapper, they associate with hard bottom reefs and wrecks, rarely moving from their territories except to spawn. This makes them easy targets for over fishing since they don’t move to avoid heavy fished areas (at least not very far).
  5. Snappers spawn in aggregations, massive schools offshore. Experienced fisherman can locate these spawning aggregation and easily wipe out large amounts of the largest most fecund (potentially reproductive) fish.

So what I want fisherman to take away from this is that the red snapper population problem is one of many many dimensions. Just because you can catch a boat load of them in Jacksonville doesn’t mean the population is near as numerous, and may actually be struggling in some other areas. Offshore bottom fish are particularly vulnerable to overfishing which is why most have strict regulations.

I will not pretend to say I believe the fisheries have been managed in the best way over the years, they certainly have not. But I just wanted to bring an appreciation to how difficult the task of fisheries management can be and to shed a new light on one of the problems most fisherman can relate too.
