V. dos; FREITAS, L. E. L. de; FRACALOSSI, D. M. Apparent digestibility coefficients (ADCs) of nine protein ingredients were determined for pirarucu Arapaima gigas, a Neotropical fish species with great aquaculture potential in the Amazon. ADCs of c... ... Repository: BDPA Publication year: 2019
Comparative proteome and peptidome analysis of the cephalic fluid secreted by Arapaima gigas (Teleostei: Osteoglossidae) during and outside parental care. Author(s): TORATI, L. S.; MIGAUD, H.; DOHERTY, M. K.; SIWY, J.; MULLEN, W.; MESQUITA, P. E. C.; ALBALAT, A. Parental investment in Arapaima gigas includes nest building and guarding, followed by a care provision when a cephalic fluid is released from the parents' head to the offspring. This fluid has presum... ... Repository: BDPA Publication year: 2017
