Crescimento de juvenis de Pseudoplatystoma reticulatum e Pseudoplatystoma spp. em viveiro Growth of juvenile Pseudoplatystoma reticulatum and Pseudoplatystoma spp. in pond

The growth of the ?sh is an important factor that determines the potential of various species for economic exploitation. The aim this work was evaluates the growth juvenile cachara and hybrid grown in pond. Information was collected of weight and morphometric measures during the experimental period. Total length gain, body height gain, body width gain, weight gain, growth index, morphometric ratios and body percentage were calculated. The methodology of generalized linear models was used, considering Gamma distribution and inverse link function. The variances and averages of variables were submitted tests F of the Snedecor and Chi-Square, respectively. The hybrids gained more weight in second and
