This species has been widely distributed in the rivers of Algeria, and was studied for the first time in the Beni Haroun dam. The samples were obtained using a trammel net during the years of 2015-2016. On a total of 168 specimens examined, the biometric and anatomical measurements have shed light on a multitude aspects related to the growth and development of fish studied in relation to the infestation by endohelminth parasites. The evaluation of parasite indices according to size, sex and seasons showed that all the specimens of this fish species were likely to be parasitized, but with varying degrees.

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 studying the growth of an autochthonous species (Luciobarbus callensis), populating the dam of Beni-Haroun (Mila city, northeast Algeria), and is known by its socio-economic value and aquaculture interest. The study was conducted on a sampling of 257 fish individuals during the year 2015 – 2016. The age of Luciobarbus callensis was determined by using the described method or the scalimetry method, providing an easier sampling and reading procedures, and also a high precision. Fish sexes were identified via the observation of gonads, by naked eye based on gonad shape and color, where the number of females was higher (165) than males (92). The obtained results revealed a maximum longevity ...

This study was, therefore, aimed to investigate the ectoparasite copepods, infesting 277 fishes including 135 of Cyprinus carpio (Linnaeus, 1758) and 142 of Abramis brama (Linnaeus,1758), collected from Beni-Haroun dam (Mila, northeast Algeria). The fishes were subjected to some morphometric measurements and gill dissections and the harvested parasites were afterwards stored and identified. The parasitic indices were determined to examine the effect of size, sex, season and microhabitat on the parasitic infestation by using χ2 test. The gill examination of individuals of the two host fishes led to harvest 135 copepods, including 127 individuals from Cyprinus carpio belonging to five species (Ergasilus sieboldi,...

Some parasitic copepods are responsible for a massive mortality of stocks, however, there has been a lack of knowledge on the Algerian freshwater fish. Therefore, the present work aimed to study the infestation of copepod ectoparasites of 499 fish, including 257 individuals of Luciobarbus callensis (Valencienne ,1842) and 242 of Carassius carassius (Linnaeus, 1758) species found in Beni Haroun Dam (Mila, Algeria). The fish were subjected to some morphometric measurements, and thereby, a gill dissection was measured, harvested, preserved and identified, as well the parasitic indices were calculated. The effect of some parameters (size, sex season, and microhabitat) on the parasite infestation was tested by using χχ2 test. The gill examination of the individuals of the two host populations led to an inventory of eight parasitic species in Luciobarbus call...
