Trade-offs between ontogenetic changes and food consumption in Brazilian silverside Atherinella brasiliensis from two tropical estuaries.

Journal of Fish Biology, 2020
Salinity variation in estuarine environments influences the distribution of fish species as well as the availability of food resources to be used by them. This study examines the effect of the range of salinity on the trade-off between growth and feeding

Reproductive Rhythmicity of the Atlantic Silverside

Transactions of the American Fisheries Society, 1984
Abstract The reproductive periodicity of the Atlantic silverside Menidia menidia was studied at two locations on the North Edisto River estuary in South Carolina during March-July 1976–1978. Spawning runs occurred in the upper intertidal zone and coincided precisely with daytime high tides.

Female reproductive biology of the silverside Odontesthes regia

Fisheries Research, 2011
Abstract Histological observations of gonads, size frequency distribution of oocytes, seasonal changes in the gonadosomatic index and fecundity were used to assess the reproductive biology of females of the silverside Odontesthes regia from October 2006 to November 2007 in southern Chile. Six developmental stages were characterised as a function of

Within-population morphological differences in the New World silverside Odontesthes argentinensis inhabiting two coastal lagoons of Uruguay (southwestern Atlantic)

, 2020
Silversides are renowned for their phenotypic plasticity with different populations coexisting as incipient species. The New World silverside Odontesthes argentinensis is an estuarine-resident fish with known populations inhabiting the Rio de la Plata ...

Poblana alchichica: A threatened silverside species?

SIL Proceedings, 1922-2010, 2010
The status of local endemic species such as Poblana alchichica is difficult to assess, and therefore conservation measures are not efficiently implemented. However, in recent years several methods have helped compare status of different species based on objective criteria.

Overwintering of the Inland Silverside in Southern Illinois

North American Journal of Fisheries Management, 1988
Abstract The objectives of this study were to determine if the inland silverside Menidia beryllina could survive over winter in southern Illinois, north of its native range, and if power-plant cooling reservoirs or aquaculture systems could be used to maintain brood stocks of the species during especially cold winters.

Androgen synthesis in the silverside Odontesthes bonariensis

2008
Though it is generally accepted that steroids are able to affect the sex ratio in many teleost species, the role of androgens in the sex determination/differentiation process in fish species with temperature-dependent sex determination systems (TSD) has not been established.

Mississippi Silversides, Menidia audens (Atherinidae), Established in California

Transactions of the American Fisheries Society, 1970
Abstract Menidia audens were introduced into Upper and Lower Blue Lakes, and in Clear Lake, Lake County, during the fall of 1967, as a result of previous study indicating a high potential for this species as a biological control agent for aquatic midges, and as a forage species for game fishes.
