Fish Talk . . . Really!

Who knew?

Fish talk. And often they talk about sex.

Of course, they don’t “speak” in words because they don’t have vocal cords.

Rather, they are “soniferous,” meaning they make sounds. They use their teeth, bladders, and other means to grunt, croak, click, drum, and squeak, saying things like “Swim over here, fishy, fishy” and “Get outta here, you fat flounder. This is my nest.”

Up to 1,000 species of fish are believed to be chatty and, yes, the sunfish family, which includes bass, is in the conversation. In fact, hydrophones were used to study bluegill courtships sounds more than 40 years ago.

“Some centrarchids do make noise,” said Gene Wilde, professor of fish ecology at Texas Tech. “But it seems to be only during breeding season, and we’re not sure how they do it. Possibly by rubbing mouth parts together.

“Some species make sounds year around,” he added. “But most fish sounds are associated with breeding. For example, drum attract mates that way.”

The gizzard shad, an important forage fish, is one species that makes sounds year around, and what a Texas Tech graduate student recently discovered about those sounds when the fish are exposed to environmental stressors is significant.

“Gizzard shad are widespread, in about 2/3 of the country,” said Matt Gruntorad. “They produce calls when stressed, and these calls could be an early warning system when there’s a  (water quality) problem. They could help protect valuable game fish and water supplies.”

The Texas Tech researcher exposed the shad to various levels of salinity, pH, and toxicity (ammonia hydroxide). As levels increased, the fish became louder--- up to a point. At the highest levels, they were quieter. “There could be a threshold when they are too stressed to make sounds,” Gruntorad said.

Sounds made by fish of 2 inches or so were too soft to analyze. But 12-inch shad yielded strong signals for the hydrophones.

Even so, though, their calls would be difficult, if not impossible, for the human ear to detect.

“They don’t croak,” the graduate student said. “Their calls are very simple, very quiet. They release gas through the anal duct. It’s like a fish fart.”

Compared to saltwater, much work remains to be done to recognize and understand sounds made by fish in freshwater, Gruntorad said.

Wilde agreed, adding that drum make their unique sound by playing muscles against their swim bladders, while catfish create their characteristic “grunts” by rubbing the pectoral spine against the pectoral girdle. “Smaller fish click their teeth together,” he said.

The fish behavior expert also said that any fish sounds that an angler hears above the water is not the same as what would be heard under.

“It’s tough for people to hear fish noises (in the water),” he explained. “For schooling fish, like herring, sound is a close-range thing to keep the integrity of the school.”

With tongue planted firmly in cheek, Wilde assured animal rights activists that fish do not scream when hooked. “We put a hydrophone in a phone where we catch a lot of bass,” he said. “And that did not happen.”

 Fish Sounds

 One of the reasons that the learning curve regarding soniferous fish has improved in recent years is that researchers have modified their diving gear. For years, they were unaware of conversations because sounds of bubbles released by SCUBA gear masked them, as well as frightened the fish.

Now researchers use self-contained breathing systems so no gas bubbles are released.

“Increasingly scientists are discovering unusual mechanisms by which fish make and hear secret whispers, grunts, and thumps to attract mates and ward of the enemy,” said LiveScience.com.

“In just one bizarre instance, seahorses create clicks by tossing their heads. They snap the rear edge of their skulls against their star-shaped bony crests.”

Meanwhile, the swim bladder, also used to control buoyancy, is one of the most common instruments for fish sounds. A muscle attached to the swim bladder contracts and relaxes in rapid sequence, causing the organ to produce a low-pitched drumming sound.

Some species use stridulation, pushing teeth and/or bones together. And still others use body movements to make sounds by altering water flow.

 Fish Hearing

 Yes, fish have ears --- of a sort. Actually they possess ear bones known as “otoliths.” Also used to age fish, they vary in shape and size according to species, just as human ears vary from individual to individual.

Only fish otoliths can’t be seen eternally.

Sound travels through water as waves or vibrations, and, because a fish’s body is of similar density, the waves pass through it. But they cause the ear bones to vibrate.

Additionally, a fish can sense vibrations and movement with its lateral line, which is a sensory organ consisting of fluid-filled sacs with hairlike cells, open through a series of pores along the side. And the swim bladder works in a similar fashion, according to Robert Castenada, founder of Livingston Lures, which mimic distress sounds from shad.

“A fish has three ways to pick up sounds, but only one way to see and smell,” he added. “That’s why, in my opinion, sound plays the biggest role in bass locating prey.”

But because sound travels farther and 4.4 times faster in water than in air, a fish can struggle to hear through the “clutter” of outboard engines and recreational activity, according to Hydrowave, which makes a sound device designed to attract bass and other game fish by imitating the sound of baitfish and predatory fish feeding on them.

“This speed, combined with the poor visibility characteristics of water is the reason that a fish is so dependent on vibration and water displacement . . . for location of prey,” the company said.

“The source of sound clutter is always present. This forms the basis of how fish have developed keen senses that allow them to specifically identify clutter from prey and feeding activities of other fish.”

Four-time Classic winner Kevin VanDam said that the Hydrowave works in two ways. “It excites the fish because they hear the sound of other bass eating,” he explained. “And it excites the bait. It draws it up.”

On the other hand, Castenada’s topwaters, jerkbaits, wakebaits, and crankbaits replicate the distress sounds that shad make when they are assaulted by bass. For years, anglers have used rattling baits. But the lure designer said those just make noise, while his make “an actual biological noise.”

Setting Hook Properly Is Key for Catching More Fish

Photo by Robert Montgomery

(Author's note: This article was written a few years ago for young anglers. But the advice applies to anglers of all ages who want to catch more fish.)

You feel the fish bite. It even pulls the line and bends your rod. But you don’t catch it.

What happened?

Maybe the fish was too small to get the hook in its mouth.  Maybe it bit and spit.

Or maybe you didn’t set the hook properly.

Along with mastering a level-wind reel, one of the biggest challenges for young anglers is learning how to set the hook.

Remember when you first went fishing? When you saw your bobber bounce that first time, you were so excited that you started reeling as fast as you could. Probably your dad or your grandpa or maybe even your mother was yelling, “Set the hook! Set the hook!”

You just kept reeling. You didn’t know what “set the hook” meant.

Now, you know that it means to pull back on the rod when you see or feel a fish bite, and that’s what you do. But still you miss bass. What’s wrong?

Maybe nothing. We all miss fish occasionally--- even professionals such as Kevin VanDam.

But you definitely can improve your catch rate if you will listen and learn from the best.

“With a Texas rig, you have to drive the hook through the plastic,” says VanDam. “I like to do it with a little slack line. I drop the rod tip and hit real hard.”

Others say to tighten your line all the way before setting the hook. The problem with that is a tight line can make it easier for a bass to feel you--- and possibly drop the bait--- before you set the hook.

Whichever method you use--- tight or a little slack--- act quickly when you feel a bite on a soft plastic. And jerk hard.

With another single-hook bait, the spinnerbait, you should pull more than jerk. “Let the rod load up and pull into the fish,” VanDam explains. “Reel hard and pull.”

“Load up” means the weight of the fish is putting bend into the rod, especially the tip.

Topwaters and crankbaits, meanwhile, make it easier to connect with the fish because they have treble hooks. But be careful.

“You want to let the fish load up on a crankbait or topwater,” says Florida pro James Charlesworth. “And then you want to do a sweeping hook set. If you set too hard, you can jerk the hooks right out.”

VanDam adds, “Today’s hooks are so good, so sharp, that you don’t need to set the hook hard.”

With a topwater, the Michigan pro advises that you wait until you feel the weight of the fish pulling down before you react.

It’s tough to do that when you see a big bass wallowing all over your bait. Your first instinct is to jerk as soon as you see the fish going after the topwater. Setting the hook too soon, however, will just pull the bait away from the bass.

If you’re fishing with a spinning rod, light line, and finesse baits, you don’t want to jerk at all. Doing so might break the line. Plus, you don’t need as much force to stick a bass with a light wire hook as you do with a big worm hook.

Instead of jerking, use a “reel set.” When you feel the fish, reel as fast as you can, allow the rod to load up and pull straight up and back.

“I do a lot of smallmouth fishing with a spin rod,” says VanDam. “With this hook set, if you miss the fish, you can let the rod back down, and the smallmouth will be right there to hit the bait again.”

Join KVD, Ike, and Other Pros in Supporting Autism Awareness

Here’s a shout-out to professional anglers Kevin VanDam, Mike Iaconelli, John Crews, Fred Roumbanis, Kelly Jordon, Edwin Evers, Bub Tosh, and Scott Martin. They all support autism awareness by displaying the “Fishin’ with a Mission” decal on their boats or tow rigs.

“Fishin’ with a Mission” is the creation of Eli Delany, a Massachusetts angler whose son Luke has autism. And he’s not the only one.

According to a pediatrics report at Talk About Curing Autism website, 1 in 91 children has autism, with a new case diagnosed nearly every 20 minutes. No medical detection or cure for the disability exists, which is why being aware of its symptoms, especially in children, is so important.

You also can support autism awareness by educating yourself at Delany’s website and buying a decal.

In a letter to the sponsors of the above anglers, Delany said, “In today’s very difficult times, your sponsored angler was willing to give away very valuable advertising space in support of children and families affected by autism.

“This shows true humility and a genuine willingness to give back to the sport and the community. You should be very proud that you sponsor such an individual.”

Fishin' With a Mission to Raise Awareness About Autism

This website isn’t just about activism to promote and protect recreational fishing. It’s also about using the power of our sport to support good causes.

One of those is autism awareness. My friend Eli Delany leads the charge on this one at MyLittleBuddysBoat. His little buddy is son Luke, who has autism.

But Eli and Luke also have some great company in raising awareness about the disorder that is now being diagnosed in 1 in every 92 children or about 1 in every 50 households, since most families have two children or more. Bass pros Mike “Ike” Iaconelli, Kevin VanDam, Edwin Evers, Kelly Jordon, Scott Martin, Fred Roumbanis, and Bub Tosh generously support the campaign.

Delany raises funds to benefit the cause by selling Fishin’ with a Mission decals on his website. “At the end of 2010, we were able to make our first donation to purchasing life vests and swim boards for the aquatics program at the New England Center for Children (school for autism treatment and education),” says Eli, who adds that Ike has been “tireless” in his support.

“It’s also very humbling to have the continued support of KVD who still displays the decal right next to his name on this boat,” he says. “Considering what he is achieving is unheralded in our sport, I’m incredibly honored to have his continuing support when there are many other worthwhile charities that he could be supporting just as easily.”
