Sciaenidae

(Redirected fromCroakers)

Sciaenidaeis afamilyofray-finned fishesbelonging to theorderAcanthuriformes.[3]They are commonly calleddrumsorcroakers[3][4]in reference to the repetitive throbbing or drumming sounds they make.[5]The family consists of about 293[4]to 298 species[6]in about 66[4]or 67 genera.[3]

Taxonomy

edit

Sciaenidae was first proposed as a family in 1829 by the FrenchzoologistGeorges Cuvier.[2]The 5th edition ofFishes of the Worldclassifies the family in thesuborderSciaenoidei,alongside the rover familyEmmelichthyidae,in the orderAcanthuriformes.[3]Other authorities classify the Sciaenidae and the Emmelichthyidae asincertae sediswithin the seriesEupercaria.[7]TheCatalog of Fishesretains this family within the Acanthuriformes but does not recognise the suborder Sciaenoidei.[8]

The 5th edition ofFishes of the World,FishbaseandCatalog of Fishesdo not recognisesubfamilieswithin the Sciaenidae[3][4][8]but many workers on these fishes do recognise subfamilies and tribes within the family. For example, in 1989 Kunio Sasaki erected a number of subfamilies andtribes.[9]

Genera

edit

The following genera are classified within the family Sciaenidae:[6]

Juvenilespotted drumfish,Bonaire,Netherlands Antilles
Adult and juvenile spotted drumfish,St. Kitts

Etymology

edit

Sciaenidae takes its name from itstype genusSciaenawhich is derived from theGreekskiaina,which was used to refer to marineperch-like fishes.[12]

Characteristics

edit

A sciaenid has a longdorsal finreaching nearly to the tail, and a notch between the rays and spines of the dorsal, although the two parts are actually separate.[13]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 usuallyinferior.Theircroakingmechanism involves the beating of abdominal muscles against theswim bladder.[13]

Sciaenids are found worldwide, in both fresh and salt water, and are typicallybenthiccarnivores, feeding oninvertebratesand smaller fish. They are small to medium-sized, bottom-dwelling fishes living primarily in estuaries, bays, and muddy river banks. Most of these fish types avoid clear waters, such as coral reefs and oceanic islands, with a few notable exceptions (e.g.reef croaker,high-hat,andspotted drum). They live in warm-temperate and tropical waters and are best represented in major rivers inSoutheast Asia,northeastSouth America,theGulf of Mexico,and theGulf of California.[13]

In the United States most fishers consider freshwater drum to berough fishnot suitable for eating, similar tocarp,gar,andbuffalo fish,although there are a number of people that enjoy fishing for these species and eating them, despite their limitations.[14]

Fisheries

They are excellent food and sport fish, and are commonly caught by surf and pier fishers. Some are important commercial fishery species, notablysmall yellow croakerwith reported landings of 218,000–407,000 tonnes in 2000–2009; according toFAOfishery statistics, it was the 25th most important fishery species worldwide.[15]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).[15] 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 threats. 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.[16]

Croaking mechanism

edit

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.[5]The croaking mechanism is used by males as amating callin some species.

To produce the croaking sound, special muscles vibrate against theswim bladder.[17]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 centraltendonthat 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.[18]In some species the sonic muscle fibres are only present in males. These muscles strengthen during themating seasonand are allowed to atrophy the rest of the time, deactivating the croaking mechanism.[17]In other species, most notably theAtlantic 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.[17]

Croaking in communication

edit

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 allowsbottlenose dolphinto easily locate large groups of croaker and drum as they broadcast their position, indicating large amounts of food for the dolphins.[17]
