1. Drumming: Fish with muscles linked to the swim bladder can make deep sounds like drums. Redfish and croakers are well-known for this.
2. Growling: Fish that are aggressive or territorial, like Grouper, make growling sounds by grinding their teeth or by using their lower caudal fin against the swim bladder.
3. Grunting: Many fish grunt as a territorial signal. It may sound like a pig. The origin of these sounds can be the dorsal fin or the anal fin.
4. Popping: Pops and clicks made by fishes like Anglerfish are used to attract prey. This sound is created by opening and closing the mouth and moving water over the swim bladder.
5. Rasping: Parrotfish use rasping sounds to communicate and mark their territory. They make these sounds by rubbing their upper caudal fin and pharyngeal teeth.

Recognizing the special sounds of fish helps anglers and researchers identify them better. Listening to the fish’s sounds can help anglers know what kind of fish they have and increase their chances of catching one.

Audio examples and spectrograms of select fish species’ vocalizations

Fish vocalizations are essential for recognizing different fish species. Audio samples and spectrograms can help decode the fish sounds and identify the species.

Oyster Toadfish: Grunting sounds are made by contracting their swim bladder muscles. The sound is heard when the swim bladder vibrates and amplifies the sound. Listen for 100-150Hz frequency range and the timing of the grunt.

Haddock: Produce loud, rumbling sound by rubbing the lower lobe of the caudal fin against the preopercle bone. Listen for the low-frequency, rhythmic sound lasting several seconds.

Cod: Drumming sound is created by contracting muscles around the swim bladder. Listen for the low-frequency drumming sound that varies in pitch and duration.

Striped Bass: Vibrate muscles around the swim bladder to make sounds. Amplified by the gas-filled swim bladder, then expelled through the mouth. Listen for a 100-200 Hz frequency range and the timing of the pulses.

Each fish species uses sound for various reasons like mating, defense, and communication. Identifying fish species by their vocalizations can help to understand their behaviour and biology.
