Editorial 2018: The Croatian Journal of Fisheries: Ribarstvo 80th Anniversary

Abstract

The Croatian Journal of Fisheries (Croat J Fish) was launched 80 years ago, in 1938, as Ribarstvo, so the current issue of Croat J Fish celebrates this significant event. Since 1992, the Journal was issued quarterly on a regular basis under the name Ribarstvo. However, in 2012 the Journal changed its name to Croatian Journal of Fisheries: Ribarstvo to attract more international audiences. The scope of the Journal has not changed much during its development and has mainly focused on ichthyology, aquaculture, ecology, fish pathology, marine and inland waters and other issues related to fisheries. Nowadays, the Journal tends to be a highquality open-access scientific journal, visible online, of interest to a wide scientific community. Expanding the number of international associate editors also indicates this process. In the segment of publishing strategies, more effort is needed to increase citation activity of the Journal. The Editorial 2018 also provides information on the articles published and the list of reviewers who participated in the review process in 2017.

Evaluation of Genetic Damage in Oreochromis mossambicus Exposed to Selected Nanoparticles by Using Micronucleus and Comet Bioassays

Abstract

The purpose of the present study is to extend knowledge on the adverse effects of nanoparticles by evaluating genotoxicity as environmental risk assessment in Oreochromis mossambicus. Fish were exposed to sublethal concentrations of the selected nanoparticles, namely silicon dioxide (SiO2NPs-12mg/L), aluminium oxide (Al2O3NPs-4mg/L), titanium dioxide (TiO2NPs-16.4mg/L) and iron oxide (Fe3O4NPs-15mg/L) for short-term (24, 72 and 96 h) and long-term durations (15, 30 and 60 days). Genetic damages such as cytoplasmic, nuclear and DNA damage were measured in the erythrocytes of fish by using standard genotoxicity tests such as micronucleus test and comet assay. The frequencies of micronuclei along with nuclear and cytoplasmic abnormalities were scored and compared with the control group. The intensity of micronuclei along with other nuclear and cytoplasmic anomalies are found to be increased significantly (p<0.05) in time-dependent manner in all exposure groups when compared to the control group, thereby indicating chromosomal damage as a result of contact with nanoparticles. The tail length and percent of tail DNA within the comet significantly (p<0.05) increased in time-dependant manner after exposure to all nanoparticles, demonstrating an increase in DNA damage. Taken together, by using micronucleus test and comet assay, it is evident that the selected nanoparticles at sublethal concentrations induced genetic damage in Oreochromis mossambicus.
