It’s early fall and you’re standing on a muddy bank watching tide ebb away. Thirty feet off, a big redfish busts the surface as it pursues crab on seagrass fringe. The rush of the sight fishing experience hits your heart and so does weight decision that stares back at you. Should I hook this fish, which would violate state law and keep me from dinner? Or should I release her to swim another day? That’s when what you know meets your gut. It’s also why knowing how weight relate to length is important on the water.
Before you ever set the hook, you can use this chart (above) to make that call, point-blank. That’s important information to take away since it details exactly how these fish accumulates their mass. In particular, the chart highlights the most important visual indicator in that graphic: the slot limit zone, which defines the legal fish size limit in almost every state. They’re typically anywhere from eighteen inches on the low end to twenty-seven inches on the upper limit. This establishes a very thin line for us to cut across during heat of battle, when our hands are wet, cold and covered in mud and we’ve got to estimate on a mucky measuring board.
Why Fish Size Matters for Anglers
According to the info-graphic however, if a redfish measures fifteen-inches around in your net, it may appear quite large but it’s actually sub-legal by biological standards. That means it has to go right back into the water instantly to protect young fish. On the other hand, anything over that twenty-seven-inch mark goes into safe harbor no matter how tempting its meat might be for your hungry stomach.
To a lot of anglers, it’s surprising how unevenly red drum gain weight; most assume they pack on roughly equal amounts of poundage for every inch of length. But the numbers reveal an exponentially increasing chart, one where knowledge and appropriate tackle can be extremely rewarding… and waiting pays off. A 22-inch redfish weights approximately five pounds, a doable dinner-fish that can be handled with reasonable rod-and-reel combos. At thirty inches, however, there’s a dramatic increase in the structure of the fish (girth) and you’re looking at a fifteen pounder. And that change necessitate beefier braids and stouter rods.
Knowing the transition prevents you from tying on six-pound test and heading offshore hoping to catch bull reds. This happens far more often because of a poor choice in tackle instead of a lack of skill. It’s less about reputation and more about aligning your tackle with the fish’s physical make-up.
Add a wrinkle: Tailing behavior adds another layer to the connection between strategy and size. On one end of the spectrum, smaller slot fish, cruising shallow flats singly and in twos, root out small crabs and shrimp from grass. Encounters are delicate, and light fluorocarbon leaders is needed to avoid spooking wary targets. On the other hand, bull reds behave more aggressively when schooling along deeper channels and inlets on their late-summer/fall spawning runs. As the chart indicates, those bigger fish top forty inches and easily goes to nearly fifty pounds or more. They don’t get tired quickly. Their huge endurance means a brief release becomes a drawn-out fight should you be unprepared for such a challenge.
Using circle hooks is more than just good conservation ethics; it is also a matter of mechanics. Circle hooks is less likely to hook a fish in the gut, and increase the odds of survival for those you choose to release.
This hidden factor that impacts all of it is temperature. Redfish are incredibly active on shorelines from sixty-five to eighty degree water temperatures. When temperatures is outside this range, they will stay deep in the channels or simply lie still, which will change how you predict their length. The bigger the fish, the less actual time they have to fight since cold water slows their metabolism. Hot summer days push them into early morning bites only. Knowing this allows you to manage what you expect regarding when and where size limits is most important.
For anglers, fishing red drum is a sport and a conservation measure. In protected areas, they can live for many decades and reach ages well over forty years old. During spawning season, every big female deposit millions of eggs into the estuary ecosystem where she knows her offspring will thrive. This ensures another generation of tiling flats fish can be enjoyed by future generations of redfish anglers.
It’s obvious; measuring before keepers seems like an easy rule to follow, but rushed judgment or misunderstanding local rules results in violations daily. Just take a few more seconds to double check against your bump board. You would of protect yourself from a fine and protect the resource from being over harvested. Holding them flat until they swim away strong is the best way to release a bull red while preserving the very biology that has made them such a legendery fishery. The next time you spot that dark form rolling on the surface remember that restraint can be the largest catch of all.
