Fish Sound Production: The Swim Bladder
Acoustics Today, 2022Analogous to the syrinx in birds and larynx in mammals, the swim bladder is a major sound-producing organ in fishes. It also functions in hearing and is responsible for most returns from sonar. Historically, the swim bladder has been modeled as an underwater resonant bubble, whereas we provide evidence for a forced-response model in which viscous ...

Swim bladder as an alternative biomaterial for bioprosthetic valves
Biomaterials Science, 2021Valvular structural deterioration and calcification are the main indications for secondary intervention after bioprosthetic valve replacement, promoting an urgent requirement for more durable cardiovascular biomaterials for clinical applications.

Neoplasms in the swim bladder of juvenile cod
Doklady Biological Sciences, 2011340 The mariculture of anadromous and marine fish steadily develops in many countries worldwide. The cod is one of promising species for mariculture. The improvement of biotechnology for mass propagation of this species necessitates clarification of the causes of poor quality of juvenile cod.

The swim bladder is a common target of infectious disease conditions. Primary bacterial and fungal infections due to direct invasion of the pneumatic duct occur in physostomes. A wide variety of Gram-negative and Gram-positive bacteria have been implicated in infections of the swim bladder including acid-fast Mycobacterium spp.

Detecting Swim Bladder Inflation in Fingerling Walleyes
The Progressive Fish-Culturist, 1993Abstract The lack of swim bladder inflation has been recognized as a problem in intensively reared walleyes (Stizostedion vitreum) for many years. This phenomenon has also been recently observed in extensively reared walleye fingerlings. Four methods for detecting the presence of an inflated swim bladder – light table, anesthesia, saltwater float, and ...

Collagen films from swim bladders: Preparation method and properties
Colloids and Surfaces B: Biointerfaces, 2008This paper describes the preparation and characterization of collagen films extracted from swim bladders of three species of tropical fishes: Arius parkeri (Gurijuba), Cynoscion acoupa (Pescada Amarela) and Cynoscion leiarchus (Pescada Branca). Collagen was extracted under acidic conditions (CH(3)COOH, 2.5 pH) and precipitated by the addition of NaCl ...

Swim-bladder surfactants of Amazon air-breathing fishes
Canadian Journal of Zoology, 1978Minimum surface tension and phospholipid composition of fish lung and swim-bladder wash and tissue extract were determined on an obligate water breather, Hoplias malabaricus, two species of facultative air breathers, Hoplerythrinus unitaeniatus and Erythrinus erythrinus, and two species of obligate air breathers, Arapaima gigas and Lepidosiren ...

Nature, 1958
THE enigmatic secretion of gas into the teleostean swim-bladder has been attributed to the acidification of the blood bathing the gas gland epithelium1. The resultant local changes of pH, pCO2 and pO2 are thought to be sequestered from the rest of the circulation by counter-current exchange in the rete mirabile.
