Trophic Strategy

provided by Fishbase
Was observed to feed at virtually all times of the day, indicating that this fish is neither strictly diurnal or nocturnal foragers. Feeds in groups. By preying on benthic meiofauna and macrofauna, these gobies transfer the immense productivity of the estuary to higher trophic levels (Ref. 26474).

Biology

provided by Fishbase
Inhabits coastal lagoons and brackish bays at mouth of freshwater streams (Ref. 2850). IS subjected to wide variation in salinity (1-28 ppt.) and temperature (9-25°C) both within and among habitat types. The substrate and vegetation can also differ among lagoon, creek and marsh habitats (Ref. 26474). Feeds mainly on crustaceans, dipteran larvae, gastropods, and invertebrate eggs (Ref. 26474). Oviparous (Ref. 56079). Males construct nesting burrows (Ref. 56079).

Northern tidewater goby

provided by wikipedia EN

Eucyclogobius newberryi, the Northern tidewater goby, is a species of goby native to lagoons of streams, marshes, and creeks along the coast of California, United States. The Northern tidewater goby is one of six native goby species to California.[2][3][4]

Etymology

The genus name translates as "true cycloid goby", referring to the scales, while the species epithet is in honor of J. S. Newberry[5][6] (1822-1892), an American geologist, physician and explorer, who collected fishes for the species describer, Charles Frédéric Girard, just not this species.[7]

Description

A small fish, only rarely longer than 5 cm (2 in), the northern tidewater goby is elongate with a blunt tail. Color is a mottled gray, brown, or olive; living fish are translucent or mostly transparent. Tidewater gobies, like many fish, exhibit countershading and tend to be mottled slightly darker on the dorsal side. The upper part of the first dorsal fin is clear or cream-colored, while the second dorsal is longer than the first, and close in size to the anal fin.

The large mouth extends back to or past the posterior edge of the eye, and is angled upwards. The eyes are spaced far apart. Unusually among gobies, the scales are cycloid instead of ctenoid; they are always absent from the head, and often from the underside too.

Breeding individuals will demonstrate color changes, with the males becoming more black with white spots as females become tan or reddish-brown with golden or dark-brown sides. Females may also take on a darker color while fighting.

Similar fish include the longjaw mudsucker, which can be distinguished from the northern tidewater goby by its more horizontal mouth and shorter rays in the anal fin compared to the 2nd dorsal fin.

Distribution and habitat

Their range extends from Tillas Slough at the mouth of the Smith River in Del Norte County, California, south to Agua Hedionda Lagoon in San Diego County.[8] While once recorded in at least 87 coastal locations, they are now gone from many, including San Francisco Bay, although they can still be found nearby at Rodeo Lagoon in Marin County[9][10] and in San Pedro Creek in Pacifica.[11]

Despite the common name, this goby inhabits lagoons formed by streams running into the sea, as well as semi-closed estuaries. The lagoons are blocked from the Pacific Ocean by sand bars, admitting salt water only during particular seasons, and so their water is brackish and cool. The northern tidewater goby prefers salinities of less than 10 ppt. Juveniles have been found as far upstream as 12 km, e.g. in Ten Mile River, Mendocino County, and San Antonio Creek and the Santa Ynez River, Santa Barbara County, sometimes in sections of stream impounded by California Golden beavers (Castor canadensis subauratus) which provide ideal slow-moving water habitat for northern tidewater gobies.[10] These fish also prefer sandy bottoms with depths of 20–100 cm, near emergent vegetation beds. The northern tidewater goby may be found in small groups of less than a dozen or occasionally in large aggregations of hundreds.

Behavior and reproduction

Male northern tidewater gobies burrow into sand and mud in the spring, cementing together grains of sand with a mucous, and shutting the burrow off from the waters above with a mucous and sand plug. Females will become aggressive during the spring and fight over a potential mate, slapping each other with their tails and biting when posturing is insufficient to drive their rivals away. The female will then attempt to entice the male to open his burrow.

If the female is successful (which may be infrequent - Camm Swift reports that 23 observed courtships resulted in only a single successful entry into the burrow by the female,) she will lay eggs on the burrow's sides and roof. The male protects the eggs for 9–10 days before they hatch. Although their life expectancy is not well known, tidewater gobies may live for only a year.

Diet

The diet of the adult northern tidewater goby consists mostly of benthic invertebrates and local insects, though their diet's exact composition can vary by season. In some lagoon populations, gobies have been found to feed on seasonally available invasive New Zealand mud snails, reflecting the fish's adaptive foraging behavior to non-native species in its environment.[12][13]

Conservation status

National Park Service biologist releasing tidewater gobies in Tomales Bay as part of a restoration program.

The northern tidewater goby was listed by the state of California for protection in 1987, and federally listed in 1994. However, there has been some controversy over this, since many populations in its range are apparently secure, and the fish is even abundant at times. However, the fish's need for specific kind of habitat means that the populations are isolated from each other, and subject to extirpation due to various human activities, such as draining of wetlands, sand bar breaches for the purpose of tidal flushing, pollutant accumulation in lagoons, and so forth. Even so, studies have shown that it is a resilient species, and populations have been successfully restored to wetlands that have been protected.

Eucyclogobius newberryi ( French )

provided by wikipedia FR

Eucyclogobius newberryi (nom vernaculaire : le Goujon de mer) est un poisson de la famille des Gobiidae qui vit dans des lagons formés par les cours d’eau le long de la côte de l’océan Pacifique en Californie.

Taxonomie

Le nom de genre signifie vrai gobie cycloïde, en référence à ses écailles, et le nom d'espèce est attribué en l'honneur de John Strong Newberry. Ce poisson était le seul membre du genre Eucyclogobius mais une autre espèce a été décrite en 2016 : Eucyclogobius kristinae Swift, Spies, Ellingson & Jacobs, 2016 (en anglais, Southern tide-water goby). Eucyclogobius newberryi fut en premier lieu classé par Girard en 1854 en tant que Gobius newberryi et actuellement Eucyclogobius newberryi (Girard, 1854).

Habitat

Sa zone d’habitat s’étend au nord de Tillas Slough à l’embouchure du fleuve Smith au Agua Hedionda Lagoon dans le comté de San Diego au sud. Dans le passé présent dans 87 localisations différentes, il a aujourd’hui disparu de plusieurs d’entre elles comme dans la baie de San Francisco.

Le poisson apprécie les lagons formés aux embouchures de cours d’eau. Ces lagons sont protégés des courants marins par des bandes sableuses. L’eau salée n’est ainsi présente que par périodes. Il préfère les salinités faibles (environ un tiers de la salinité des océans) ce qui fait qu’on le trouve essentiellement du côté proche de la rivière plutôt que de l’océan. Des jeunes poissons ont été retrouvés jusqu’à 12 km en remontant le cours de la rivière par rapport à l’embouchure.

Description

Le poisson, rarement plus grand que 5 cm a une couleur gris brun ou olive. Les jeunes poissons sont d’abord transparents ou translucides. Ils peuvent changer de couleur selon les périodes. Le mâle devient ainsi noir avec des taches blanches et les femelles rouge brun avec des pointes dorées ou foncées.

Ses écailles sont cycloïdes ce qui est inhabituel parmi les gobies. Les écailles ne sont pas présentes sur sa tête et sur son côté inférieur. Ils se déplacent en groupes de quelques poissons jusqu’à des groupes de centaines d’individus. Il se nourrit de crustacés, de mollusques et de larves d’insectes.

Espèce menacée

Le goujon fait partie de la liste des espèces menacées de l’État de Californie depuis 1987 et des États-Unis depuis 1994. Ce n’est pas qu’il est rare d’en trouver car par endroits ils sont nombreux mais parce que ces zones d’habitats sont rares et isolées les unes des autres. Les lagons sont de plus des zones sensibles à toutes les pollutions provenant des cours d’eau ce qui fait qu’il est potentiellement plus en danger que si son habitat était moins morcelé.
