“…In South America, Characiformes dominate the ichthyofauna, and species of this order make up a good part of the fish assemblages in floodplain lakes (Siqueira-Souza and Freitas, 2004;Granado-Lorencio et al, 2012;Borie et al, 2019;Dagosta and Pinna, 2019;Virgilio et al, 2020). The preference of riverine communities for consumption of species of this order has already been observed in other studies (Garcez et al, 2009;Silva et al, 2017;Begossi et al, 2019).…”

The riverine population of the Amazon Basin are among the largest consumers of fish in the world, but the consumption patterns could be regionally distinct. Moreover, their total fish catches are not fully known. The objective of this work was to estimate the per capita fish consumption of the riverine people that inhabit the Paciência Island (Iranduba, Amazonas), where there is a fishing agreement in force. A total of 273 questionnaires were applied during the first two weeks of each month between April 2021 and March 2022. The sample unit was the residences. The questionnaire contained questions about the species captured and their quantities. Consumption was calculated by dividing the average monthly capture with the average number of residents per household interviewed, which was multiplied by the number of questionnaires applied. Thirty groups of consumed fish species belonging to 17 families and 5 orders were recorded. The total catch was 3,388.35 kg and the highest monthly catch was 602.60 kg during the falling-water season in October. Daily per capita fish consumption averaged 66.13 ± 29.21 g/day, with a peak of 116.45 g/day during the falling-water season in August. The high fish consumption rate highlighted the importance of fisheries management to food security and the maintenance of the community’s lifestyle.

“…One is a partial constriction toward the back of the anterior end at the rostral edge of the sonic muscles. The constriction may represent an intermediate condition between a simple swim bladder and one that has divided into two chambers as in silver perch and several other sciaenids 25 , 50 and many otophysan fishes including some catfishes, characiforms, and cyprinids 51 – 53 . The anterior neck region bears a number of projections: a rostral pair heads toward the ears 26 and six (typically) on each side project in a caudal direction ending near the termination of the swim bladder lumen.…”

A sciaenid swim bladder with long skinny fingers produces sound with an unusual frequency spectrum

Swim bladders in sciaenid fishes function in hearing in some and sound production in almost all species. Sciaenid swim bladders vary from simple carrot-shaped to two-chambered to possessing various diverticula. Diverticula that terminate close to the ears improve hearing. Other unusual diverticula heading in a caudal direction have not been studied. The fresh-water Asian species Boesemania microlepis has an unusual swim bladder with a slightly restricted anterior region and 6 long-slender caudally-directed diverticula bilaterally. We hypothesized that these diverticula modify sound spectra. Evening advertisement calls consist of a series of multicycle tonal pulses, but the fundamental frequency and first several harmonics are missing or attenuated, and peak frequencies are high, varying between < 1–2 kHz. The fundamental frequency is reflected in the pulse repetition rate and in ripples on the frequency spectrum but not in the number of cycles within a pulse. We suggest that diverticula function as Helmholz absorbers turning the swim bladder into a high-pass filter responsible for the absence of low frequencies typically present in sciaenid calls. Further, we hypothesize that the multicycle pulses are driven by the stretched aponeuroses (flat tendons that connect the sonic muscles to the swim bladder) in this and other sciaenids.

“…The hypothesis that these anterior hypaxial bundles are the precursor to the drumming muscles found in carnivorous species is also reinforced by soundproduction abilities in at least some prochilodontids (e.g. Semaprochilodus insignis, Prochilodus argenteus, Prochilodus costatus, Prochilodus lineatus) (Godinho et al, 2017;Smith et al, 2018;Borie et al, 2019) and anostomids (e.g. Megaleporinus muyscorum, Leporinus microcephalus) (Reynalte-Tataje et al, 2013;Ramirez et al, 2017).…”

Among piranhas, sound production is known in carnivorous species, whereas herbivorous species were thought to be mute. Given that these carnivorous sonic species have a complex sonic apparatus, we hypothesize that intermediate forms could be found in other serrasalmid species. The results highlight the evolutionary transition from a simple sound-producing mechanism without specialized sonic structures to a sonic mechanism involving large, fast-contracting sonic muscles. Hypaxial muscles in basal herbivores primarily serve locomotion, but some fibres cause sound production during swimming accelerations, meaning that these muscles have gained a dual function. Sound production therefore seems to have been acquired through exaptation, i.e. the development of a new function (sound production) in existing structures initially shaped for a different purpose (locomotion). In more derived species (Catoprion and Pygopristis), some fibres are distinguishable from typical hypaxial muscles and insert directly on the swimbladder. At this stage, the primary function (locomotion) is lost in favour of the secondary function (sound production). In the last stage, the muscles and insertion sites are larger and the innervation involves more spinal nerves, improving calling abilities. In serrasalmids, the evolution of acoustic communication is characterized initially by exaptation followed by adaptive evolution.
