Curvas de crescimento morfométrico de piracanjuba (Brycon orbignyanus)

Ciencia E Agrotecnologia, 2009
Conduziu-se um experimento no setor de piscicultura da Universidade Federal de Lavras M.G., com o objetivo de estabelecer curvas de crescimento morfométrico em função do peso corporal para a piracanjuba (Brycon orbignyanus). Alevinos de piracanjuba foram cultivados em viveiros de terra e alimentados com ração comercial até atingirem peso aproximado de ...

Avaliação espermática pós-descongelamento em piracanjuba (Brycon orbignyanus, Vallenciennes, 1849) [PDF]

Revista Brasileira De Zootecnia, 2003
O experimento foi realizado com o objetivo de testar o efeito de dois meios diluidores (Glicose 5% e água de côco) no congelamento do sêmen de piracanjuba (Brycon orbignyanus, Vallenciennes, 1849) e dois descongelamentos do sêmen (60ºC durante 5 segundos e 50ºC durante 10 segundos).

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).

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.
