The influence of triiodothyronine (T3) on the early development of piracanjuba (Brycon orbignyanus)

Fish Physiology and Biochemistry, 2010
This paper reports the triiodothyronine's (T3) effects on the early growth and survival of piracanjuba (Brycon orbignyanus) produced from fertilized eggs hormone exposed. The study was carried out in two phases. In the first phase, eggs divided in 6 batches were immersed in T3 solutions: 0.01; 0.05; 0.1; 0.5 ppm; 1 ppm and control (no T3).

Physiological and biochemical changes of females of Piracanjuba, subjected to induced reproduction

Journal of Animal Physiology and Animal Nutrition, 2015
SummaryThe aim of this experiment was to compare the level of fish female stress during induced reproduction with pituitary extract by two different methods, natural and semiextruded. The reproductive efficiency was 62.5% in the seminatural treatment and 100% in the extruded.

Gradiometria fluxgate no sítio Guarani Piracanjuba, Piraju-SP

9th International Congress of the Brazilian Geophysical Society & EXPOGEF, Salvador, Bahia, Brazil, 11-14 September 2005, 2005
We present fluxgate gradiometric maps obtained at the Piracanjuba archaeological site. Our geophysical study allowed the identification of an ancient fire hearth place that was important to site understanding and coal sampling for C14 dating.

Cannibalism rate and mLeptin expression are influenced by photoperiod and diets in Piracanjuba, Brycon orbignyanus (Valenciennes, 1850) larvae

Research in Veterinary Science, 2022
Piracanjuba (Brycon orbignyanus) is a species with great productive potential, and during its larval phase, it presents intense cannibal activity. The photoperiod and diet are primary feed behaviour and cannibalism modulators to fishes. This experiment aimed to verify the effect of different photoperiods and diets in Piracanjuba larviculture.

Cryopreservation and transplantation of spermatogonia stem cells in piracanjuba Brycon orbignyanus (Characiformes: Characidae), an endangered fish species [PDF]

Fish Physiology and Biochemistry
Piracanjuba (Brycon orbignyanus) is an endangered fish species from the Neotropical region. The establishment of a cryobank using spermatogonial stem cells (SSCs) and subsequent production of a germline chimera is thus a promising strategy for such ...

Hatching, survival and deformities of piracanjuba (Brycon orbignyanus) embryos subjected to different cooling protocols

Cryobiology, 2014
Groups of one hundred Brycon orbignyanus embryos at the stage of blastopore closure were subjected to different cooling protocols. Different combinations and concentrations of cryoprotectants were tested: sucrose, methanol, ethylene glycol and dimethyl sulfoxide (Me2SO); at different temperatures (0.0±2.0°C and 8.0±2.0°C) and refrigeration times (6, 10,

Crecimiento y supervivencia de postlarvas de piracanjuba (brycon orbignyanus)

Archivos De Zootecnia, 2009
This work was conducted in the fish laboratory of the Environmental Station of Itutinga, CEMIG in January 2002. The objective was to evaluate the behavior of piracanjunba (Brycon orbignyanus) post-larvae at different stocking densities and feeding frequencies. The post-larvae were manteined into eighteen plastic rectangular-shaped boxes of 30 liters of

Optimization of Artificial Propagation in Piracanjuba Fish Brycon orbignyanus Using Cryopreserved Semen.

Cryo letters, 2017
BACKGROUND: Cryopreserved semen could facilitate procedures during the artificial reproduction in fish. Factors affecting cryopreservation efficiency are important to define efficient protocols.This study investigated the application of cryoprotectants on the quality of piracanjuba fish semen, the sperm concentration required for oocyte fertilization ...
