reaching nearly to the tail, and a notch between the rays and spines of the dorsal, although the two parts are actually separate. Drums are somberly coloured, usually in shades of brown, with a lateral line on each side that extends to the tip of the caudal fin. The anal fin usually has two spines, while the dorsal fins are deeply notched or separate. Most species have a rounded or pointed caudal fin. The mouth is set low and is usually inferior. Their croaking mechanism involves the beating of abdominal muscles against the swim bladder

fishery statistics, it was the 25th most important fishery species worldwide.[ However, a large proportion of the catch is not reported at species level; in the FAO fishery statistics, the category "Croakers, drums, not elsewhere included", is the largest one within sciaenids, with annual landings of 431,000–780,000 tonnes in 2000–2009, most of which were reported from the western Indian Ocean (FAO fishing area 51) and northwest Pacific (FAO fishing area 61).]
The future of croakers, like many other fish species in the United States and around the world is uncertain because overfishing continues to be a major threat. The population has decreased significantly which will affect their ability reproduce. In United States Croakers are managed by the federal and state governments to ensure that they're harvested sustainably.
Croaking mechanism
A notable trait of sciaenids is the ability to produce a "croaking" sound. However, the pitch and use of croaking varies species to species. The croaking ability is a distinguishing characteristic of sciaenids. The croaking mechanism is used by males as a mating call
A mating call is the auditory signal used by animals to attract mates. It can occur in males or females, but literature is abundantly favored toward researching mating calls in females. In addition, mating calls are often the subject of mate choi ...
in some species.
To produce the croaking sound, special muscles vibrate against the swim bladder
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ (anatomy), organ in bony fish that functions to modulate buoyancy, and thus allowing the fish to stay at desired water depth without having to maintain lift ...
. These muscles are called sonic muscle fibres, and run horizontally along the fish's body on both sides around the swim bladder, connected to a central tendon
A tendon or sinew is a tough band of fibrous connective tissue, dense fibrous connective tissue that connects skeletal muscle, muscle to bone. It sends the mechanical forces of muscle contraction to the skeletal system, while withstanding tensi ...
that surrounds the swim bladder ventrally. These sonic muscle fibres are repeatedly contracted against the swim bladder to produce the croaking sound that gives drum and croaker their common name, effectively using the swim bladder as a resonating chamber. The sciaenids' large swim bladder is more expansive and branched than other species, which aids in the croaking. In some species the sonic muscle fibres are only present in males. These muscles strengthen during the mating season
Seasonal breeders are animal species that successfully mate only during certain times of the year. These times of year allow for the optimization of survival of young due to factors such as ambient temperature, food and water availability, and ch ...
and are allowed to atrophy the rest of the time, deactivating the croaking mechanism. In other species, most notably the Atlantic croaker, the croaking mechanism is present in both sexes and remains active year-round. These species are thought to use croaking for communication, such as announcing hazards and location when in turbid water.
Croaking in communication
In some species, croaking is used for communication aside from attracting mates. For those species that have year-round croaking ability, the croaks may serve as a low-aggression warning during group feeding, as well as to communicate location in cloudy water. In those species that lack the ability to croak year-round, croaking is usually restricted to males for attracting mates. A disadvantage to the croaking ability is that it allows bottlenose dolphin
The bottlenose dolphin is a toothed whale in the genus ''Tursiops''. They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. Molecular studies show the genus contains three species: the common bot ...
