Biological parameters of Luciobarbus callensis populates Beni-Haroun dam, north-eastern Algeria
The fish age and growth data mainly assist many ichthyologists to understand the life history features of species and population. The growth is a major process of fish biology, and considered as one of the key processes of length-structured models of fishes. Thus, the present study was devoted to...
