RELAÇÃO PESO/COMPRIMENTO E FATOR DE CONDIÇÃO DE JUVENIS DE Hoplias lacerdae EM DUAS DENSIDADES DE ESTOCAGEM [PDF]

Revista Brasileira De Engenharia De Pesca, 2016
Este trabalho foi realizado com objetivo de avaliar a relação peso/comprimento e o fator de condição de juvenis de trairão, Hoplias lacerdae, estocados em duas densidades. Animais previamente treinados a receber dietas artificiais, com 9,6 cm de comprimento total, foram distribuídos em seis tanques de alvenaria de 5m2 cada nas densidades de 1 juvenil ...

Cardio-respiratory responses in two ecologically distinct erythrinids (Hoplias malabaricus and Hoplias lacerdae) exposed to graded environmental hypoxia

Environmental Biology of Fishes, 1993
Ecologically distinct species of Hoplias were studied as to the cardio-respiratory responses to graded hypoxia. Hoplias malabaricus maintained a constant oxygen uptake down to a PiO2 of 20 mmHg. Oxygen uptake declined markedly at lower PiO2 and, concomitantly, cardiac frequency decreased.

Optimal dietary L-glutamine level improves growth performance and intestinal histomorphometry of juvenile giant trahira (Hoplias lacerdae), a Neotropical carnivorous fish species

Aquaculture, 2022
Abstract Even though glutamine is a non-essential amino acid, its inclusion in diets can be used as a tool to optimize the intestinal health and growth of fish, reason why it has been considered as a functional amino acid. Thus, the aim of this study was to evaluate the dietary supplementation with different levels of L-glutamine for juvenile giant ...

Respiratory responses to hypoxia in relation to mode of life of two erythrinid species (Hoplias malabaricus and Hoplias lacerdae)

Journal of Fish Biology, 1992
Predominantly, Hoplias malabaricus inhabits stagnant O2 poor environments, whereas Hoplias lacerdae occurs in well‐aerated streams. The present study evaluates the influence of mode of life on O2 uptake and gill ventilation in equally‐sized (300 g) specimens of this genus at 25° C. Comparing the species, H.
