“…The main evidence that this fish produce sounds is provided by the presence of a pair of muscles, one on either side of the swimbladder, similar to those found in known vocalists (as e.g., haddock, cod, lythe (Pollachius pollachius), and tadpole-fish (Raniceps raninus)) (Sørensen 1884;Hagman 1921 Marshall 1953;Templeman and Hodder 1958). In cod, Delaroche (1809) and Sørensen (1884) describe the weak, flattened muscles which pass from the sides of the swimbladder at its anterior end to the ribs of the anterior vertebrae.…”

“…In cod, Delaroche (1809) and Sørensen (1884) describe the weak, flattened muscles which pass from the sides of the swimbladder at its anterior end to the ribs of the anterior vertebrae. Jones and Marshall (1953) label these external swimbladder muscles of the cod as drumming muscles (DM). In the European haddock, special groups of muscles attached to the ventral wall of the swimbladder defined as well as drumming muscles were described by Templeman and Hodder (1958).…”

“…Another function of the gas bladder is the use as a resonating chamber to produce or receive sound and in some species is equipped with drumming muscles (DM) for sound production. Sounds are produced by contracting DM associated with the swimbladder and thereby vibrating the swimbladder wall (Jones and Marshall 1953;Brawn 1961).…”

Sexual dimorphism of drumming muscles in European hake (Merluccius merluccius)

Dissections of mature and non-mature European hake males and females (N=142) collected in waters off the western coast of Norway and in the Bay of Biscay (France) in 2004-2006 demonstrate for the first time that this gadoid species contains drumming muscles. There were differences in drumming muscles weight with body length, sex and maturity stage. This study shows that the difference between females and males is primarily manifested during the spawning season, seen both in the French and Norwegian samples. For the mature females the drumming muscles dry weight increases only slightly, if at all, with increase in total length. For mature males there is a corresponding rapid increase. There does not seem to be any consistent difference between the average dry weight of the drumming muscles in immature male and immature and mature female hake of the same length, tested on the Norwegian samples.Our results suggest that male hake, like the males of other gadoids studied, may produce sounds in the context of spawning.

“…Physostomous fish can maintain their body density at near neutral buoyancy by retaining a certain amount of gas in their swim bladder. When the gas is exhaled, the body density becomes negatively buoyant, enabling the fish to glide during descent and rest on the bottom (Jones and Marshall, 1953). For example, Watanabe et al (2008) reported that when Chinese sturgeons, Acipenser sinensis, did not have gas in their swim bladders in deep water; the fish exhibited gliding during descents owing to their negative buoyancy.…”

Physostomous channel catfish, Ictalurus punctatus, modify swimming mode and buoyancy based on flow conditions

The employment of gliding in aquatic animals as a means of conserving energy has been theoretically predicted and discussed for decades. Several studies have shown that some species glide, whereas others do not. Freshwater fish species that widely inhabit both lentic and lotic environments are thought to be able to adapt to fluctuating flow conditions in terms of locomotion. In adapting to the different functional demands of lentic and lotic environments on fish energetics, physostomous (open swim bladder) fish may optimise their locomotion and activity by controlling their net buoyancy; however, few buoyancy studies have been conducted on physostomous fish in the wild. We deployed accelerometers on free-ranging channel catfish, Ictalurus punctatus, in both lentic and lotic environments to quantify their swimming activity, and to determine their buoyancy condition preferences and whether gliding conserves energy. Individual comparisons of swimming efforts between ascent and descent phases revealed that all fish in the lentic environment had negative buoyancy. However, all individuals showed many descents without gliding phases, which was contrary to the behaviour predicted to minimise the cost of transport. The fact that significantly fewer gliding phases were observed in the lotic environment, together with the existence of neutrally buoyant fish, indicated that channel catfish seem to optimise their locomotion through buoyancy control based on flow conditions. The buoyancy optimisation of channel catfish relative to the flow conditions that they inhabit not only reflects differences in swimming behaviour but also provides new insights into the adaptation of physostome fish species to various freshwater environments.

“…Actual use of this mechanism would be possible if two kinds of physiological measurements were combined: a measurement of the fractional rate of change of swim-bladder volume with respect to time ( _ V =V ), and a measurement of the vertical speed of the fish ( _ D). Vertical speed might in principle be measured by flow sensors in the vertically oriented canals of the lateral line system, such as the pre-opercular canal, while changes in swim-bladder volume might in principle be detected by sensing stretching of the swim-bladder wall ( Jones & Marshall 1953;Qutob 1962;Nilsson 1972Nilsson , 1980Nilsson , 2009McLean & Nilsson 1981;Wahlqvist 1985;Finney et al 2006)-at least in fish that keep the swim-bladder wall under tension (Alexander 1966). In fact, there is no need to keep track directly of the swim-bladder volume, because the fractional rate of change of swim-bladder volume is expected to be proportional to the rate of linear extension of a representative wall element divided by the total length of that element.…”

Fractional rate of change of swim-bladder volume is reliably related to absolute depth during vertical displacements in teleost fish

Fish must orient in three dimensions as they navigate through space, but it is unknown whether they are assisted by a sense of depth. In principle, depth can be estimated directly from hydrostatic pressure, but although teleost fish are exquisitely sensitive to changes in pressure, they appear unable to measure absolute pressure. Teleosts sense changes in pressure via changes in the volume of their gas-filled swim-bladder, but because the amount of gas it contains is varied to regulate buoyancy, this cannot act as a long-term steady reference for inferring absolute pressure. In consequence, it is generally thought that teleosts are unable to sense depth using hydrostatic pressure. Here, we overturn this received wisdom by showing from a theoretical physical perspective that absolute depth could be estimated during fast, steady vertical displacements by combining a measurement of vertical speed with a measurement of the fractional rate of change of swim-bladder volume. This mechanism works even if the amount of gas in the swimbladder varies, provided that this variation occurs over much longer time scales than changes in volume during displacements. There is therefore no a priori physical justification for assuming that teleost fish cannot sense absolute depth by using hydrostatic pressure cues.
