Silversides of the genus Labidesthes (Atheriniformes: Atherinopsidae)
Zootaxa, 2015The two species of Labidesthes, L. sicculus and L. vanhyningi, are herein redescribed. Labidesthes sicculus is separated from L. vanhyningi by the presence of an anterolateral process of the post temporal that is longer than it is wide (versus wider than long), a ratio of thoracic length to abdominal length greater than two (versus less than two), and ...

Reproductive Rhythmicity of the Atlantic Silverside
Transactions of the American Fisheries Society, 1984Abstract 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.

Silverside neutron detector performance
2017 IEEE International Symposium on Technologies for Homeland Security (HST), 2017We report on the performance of productized neutron detectors. The detectors employ large, thin sheets of enriched lithium in a gas-filled multi-wire proportional chamber. Using low-cost design methods, readout electronics, and manufacturing procedures, the detector has the capability of being the building block for large area networked scanning and ...

Overwintering of the Inland Silverside in Southern Illinois
North American Journal of Fisheries Management, 1988Abstract 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.

Assessment of the photoenhanced toxicity of a weathered oil to the tidewater silverside
Environmental Toxicology and Chemistry, 2000AbstractStudies were conducted to determine the interactive toxicity of a water-accommodated fraction (WAF) of a weathered middle distillate petroleum and solar radiation to an estuarine organism, the tidewater silverside (Menidia beryllina). Juvenile silversides were monitored for survival and growth during a 7-d static renewal exposure to dilutions ...

Female reproductive biology of the silverside Odontesthes regia
Fisheries Research, 2011Abstract 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

Effects of Diet on Survival and Growth of the Atlantic Silverside
The Progressive Fish-Culturist, 1980Abstract Effects of two live and seven prepared diets on the survival and growth of postlarval and juvenile Atlantic silversides (Menidia menidia) were determined. Two experiments were conducted, one with 23-day-old postlarvae and one with 57-day-old juveniles. In both experiments, growth rate and survival were greatest on the live diet of brine shrimp

Androgen synthesis in the silverside Odontesthes bonariensis
2008Though 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.

The role of amides in seminal cryopreservation of wild silverside, Odontesthes bonariensis
Cryobiology, 2016Amides were tested as internal cryoprotectants for the preservation of wild silverside (Odontesthes bonariensis) sperm. The semen was diluted in modified Mounib's medium and cryopreserved by adding 2, 5, 8 or 11% of dimethyl acetamide (DMA), dimethyl formamide (DMF) or methyl formamide (MF).
