Biology

provided by Fishbase
Usually found offshore but was also recorded from shore pools (Ref. 5299). Found in shoals (Ref. 27121). Juveniles epipelagic, adults migrate to deeper waters, and large adults are only recorded from demersal trawls (Ref. 27121). Feeds on phytoplankton and preyed upon by fishes, penguins, Cape cormorants, and fur seals (Ref. 27121). Although targeted by purse seines, it may also be caught incidentally in trawls (Ref. 27121). Prefer cooler waters of 11° to 15°C (Ref. 36731).

Pelagic goby

provided by wikipedia EN

The pelagic goby (Sufflogobius bibarbatus), also known as the bearded goby , is a species of true goby from the family Gobiidae, native to the southeastern Atlantic Ocean. It is currently the only known member of its genus.[1]

Description

It reaches a maximum length of 17 centimeters (6.7 in). It has 7 dorsal spines and 12-13 dorsal soft rays. It has a single anal spine and 12-13 anal soft rays. Its fins are dusky to black in color.[1]

Range and habitat

This goby is demersal, inhabiting depths of 0–340 metres (0–1,115 ft) in subtropical waters ranging from 11–15 °C (52–59 °F) in the coastal waters of Namibia and South Africa.[1]

The bearded goby is usually found offshore but was also recorded in shore pools. Juveniles are epipelagic, while adults migrate to deeper waters, and large adults are only recorded from demersal trawls.[1]

The gobies can stay on the ocean floor for at least 10 to 12 hours at a time in an area of de-oxygenated "toxic sludge" rich in hydrogen sulfide H
2
S
where hardly anything lives except bacteria and nematodes. When settled on the bottom, they remain alert, showing rapid escape responses. They use the toxic mud as a refuge. Their population is growing despite the fact that they are now the main prey species in this unusual ecosystem.[2]

Feeding

In 2010 was observed to feed on a species of jellyfish which was understood to be its main predator.[2][3] Jellies provide up to 1/3 of the fish's diet. It hides from mackerel amongst the jellies' stinger-covered tentacles when it rises from the seafloor for nighttime feeding.[4]

Predation

Fishes, penguins, Cape cormorants, crested terns and fur seals and jellies eat this fish.[1]

This goby hides from predators within jelly tentacles when it rises to feed and reoxygenate its blood.

Although targeted by purse seines, it may also be caught incidentally in trawls.

Sufflogobius bibarbatus ( Dutch; Flemish )

provided by wikipedia NL

Vissen

Sufflogobius bibarbatus is een baarsachtige uit de familie der Gobiidae.

Kenmerken

Sufflogobius bibarbatus wordt maximaal 17 centimeter lang en heeft donkere vinnen.

Leefwijze

Hij leeft in scholen en leeft vooral van fytoplankton en is zelf een prooi voor pinguïns, zeevogels, grotere vissen, bruinvissen en zeeberen.

Onderzoek van de Pennsylvania State University wees uit dat deze grondel ook overleeft in water met een laag zuurstofgehalte. Ze werden waargenomen in water dat in de jaren 60 en 70 van de 20ste eeuw, na overbevissing op sardines, werd overspoeld door kwallen. De grondel eet deze kwallen, hoewel de grondel zelf ook op het menu van die kwallen staat. Sufflogobius bibarbatus is hiermee één van de weinige organismen die kan overleven in het zuurstofarme water, dat hem beschermt tegen roofdieren en hem voedsel verschaft. Hoewel hij na het wegvallen van de sardine ook het enige prooidier is in de omgeving, weet hij er toch in aantal toe te nemen. Door op kwallen te leven, brengt de grondel ook die dieren weer in de voedselketen; andere dieren laten kwallen meestal links liggen. Hoe de vis tot meer dan 10 uur lang kan overleven in het zuurstofarme water is nog niet bekend. Het water is bovendien ook giftig, te wijten aan bacteriën die er waterstofsulfide uitscheiden. Het is evenmin bekend of de grondel de kwallen actief bejaagt of dode exemplaren van de bodem opruimt.

Verspreiding en leefgebied

Sufflogobius bibarbatus komt voor in volle zee in de Atlantische Oceaan nabij Namibië en Zuid-Afrika, maar werd ook al aangetroffen bij de kust. Hij leeft er op de zeebodem op dieptes tot 340 meter en bij temperaturen tussen 11 en 15 °C. De jonge exemplaren leven meer aan het wateroppervlak, de oudere exemplaren op de bodem.
