Neuropeptide Y Gene Expression Around Meal Time in the Brazilian Flounder Paralichthys orbignyanus [PDF]

open access: yesJournal of Biosciences, 2012
Neuropeptide Y (NPY) is considered the major stimulant for food intake in mammals and fish. Previous results indicate that NPY is involved in the feeding behaviour of the Brazilian flounder, Paralichthys orbignyanus. In this study, we evaluated hypothalamic NPY expression before (-2 h), during (0 h) and after feeding (+2 h) in two independent ...

Larval Culture Technique and Quality Control in Juveniles of Flounder Paralichthys orbignyanus (Valenciennes, 1839) in Argentina [PDF]

open access: yesSpanish Journal of Agricultural Research, 2009
Paralichthyds are the most economically important fish in the Southern Atlantic due to their abundance, flesh quality, high market price and increasing fishery demand. In Argentina, the first juvenile mass production of flounder Paralichthys orbignyanus i orbignyanus follow those described for olivaceus. At 40 days post-hatching (dph) and 798 degrees-

Identification, Tissue Distribution and Evaluation of Brain Neuropeptide Y Gene Expression in the Brazilian Flounder Paralichthys orbignyanus [PDF]

open access: yesJournal of Biosciences, 2010
Neuropeptide Y (NPY) is one of the most potent stimulants of food intake in vertebrates, mammals and fish. However, the present knowledge about feeding behaviour in fish is still limited and based on studies in a few species. The Brazilian flounder Paralichthys orbignyanus is being considered for aquaculture, and it is important to understand the ...

Food and Feeding Habits of Flounder Paralichthys orbignyanus (Jenyns, 1842) in Bahía Blanca Estuary, Argentina [PDF]

open access: yesHydrobiologia, 2005
Specimens of flounder Paralichthys orbignyanus (Jenyns, 1842) were collected in Bahia Blanca estuary between February 1997 and January 1998, and their feeding habits were examined in relation to season and size class. The stomach contents of 823 specimens, ranging from 70 to 875 mm total length, were analysed. Their diet included organisms from 17 taxa.

Cryopreservation of Brazilian flounder (Paralichthys orbignyanus) sperm

Aquaculture, 2008
Abstract The Brazilian flounder, Paralichthys orbignyanus, is being considered for aquaculture due to its high demand and market price. Reproduction and larviculture studies have demonstrated the feasibility of massive fingerling production, and techniques that prolong life and increase gamete viability can assist in the culture development of this ...

On the Age and Growth of Flounder Paralichthys orbignyanus (Jenyns, 1842) in Bahía Blanca Estuary, Argentina

open access: yesHydrobiologia, 2005
Estimates of age and growth of flounder Paralichthys orbignyanus (Jenyns,1842) were made by analysing fish from commercial catches in Bahia Blanca estuary (39° LS). A total of 823 fish caught by fishing fleets operating in the estuary were collected between February 1997 and January 1998.
