Material and Acoustic Properties of Swimbladders of Tilapia and Channel Catfish
Acoustically, teleost swimbladders have been considered resonant underwater bubbles. Contrary results indicating that bladders are tuned less sharply than such a bubble have been explained by damping of surrounding fish tissue. Recent findings in toadfish and weakfish, however, suggest that the …

Reproductive Manipulation and Larval Rearing Techniques of Yellow Perch (Perca flavescens)
… 6 days. The percentage of fry with inflated swimbladders and absorbed yolksacs did not differ by day 6. While T3 larvae began ingesting food earlier than T1 and T2, the percentage of fry ingesting food did not differ among treatments by day 6 (p >0.1). The total percentage of skeletal …

The effect of attenuation from fish on long-range active and passive acoustic sensing in the ocean
… fish, where scattering losses from the fish swimbladders and damping from fish flesh is most significant. Negligible attenuation was observed in previous OAWRS and POAWRS surveys because the frequency of the acoustic signals was sufficiently far from the swimbladder resonance peak of the …
