Salinity effects on osmoregulation and growth of the euryhaline flounder Paralichthys orbignyanus [PDF]

Journal of Experimental Marine Biology and Ecology, 2002
Abstract The flounder, Paralichthys orbignyanus, is found in coastal and estuarine waters of the Western South Atlantic Ocean. It is being considered for aquaculture due to its high market price and wide tolerance to environmental factors such as salinity, pH, and nitrogenous compounds.

Seasonal Seminal Quality Variations and Vitrification Prospects in Black Flounder Paralichthys Orbignyanus

Theriogenology, 2023
Long-term preservation of gametes has been identified as a tool to improve broodstock management and increase the number of juveniles produced by artificial fertilization. Paralichthys orbignyanus is an important commercial and recreational species distributed in marine and estuarine waters from Rio de Janeiro (Brazil) to the San Matías Gulf (Argentina)

Evaluation of DNase activity in seminal plasma and uptake of exogenous DNA by spermatozoa of the Brazilian flounder Paralichthys orbignyanus [PDF]

Theriogenology, 2009
Sperm mediated gene transfer (SMGT) has been successfully used in mammals, amphibians, birds, and some invertebrates. In fish, this methodology has failed or had poor efficiency for the production of transgenic specimens, presumably because the processes regulating the interaction between spermatozoa and exogenous DNA are not well understood. Therefore,

NPY and sbGnRH gene expression in juvenile and adult male Brazilian flounder Paralichthys orbignyanus Expressão gênica do NPY e do sbGnRH em machos juvenis e adultos de linguado Paralichthys orbignyanus [PDF]

Ciência Rural, 2011
The objective of this study was to evaluate neuropeptide Y (NPY) and sea bream gonadotropin-release hormone (sbGnRH) gene expression in juvenile and adult males of Brazilian flounder. Hypothalamuses from fish were sampled for total RNA extraction.

Effects of salinity on Brazilian flounder Paralichthys orbignyanus from fertilization to juvenile settlement [PDF]

Aquaculture, 2007
Abstract The Brazilian flounder, Paralichthys orbignyanus , is a promising candidate for aquaculture, especially due to the euryhalinity demonstrated experimentally for large juveniles (3 g) and sub-adults. Flounder are observed in estuaries and were already reared in fresh and salt water, however little is known with respect of salinity tolerance ...
