“…The water quality of the aquatic environment is the main factor controlling the health of cultured as well as wild fish [ 36 ]. Pollution of the aquatic environment by metals is a serious threat to the growth and survival of aquatic organisms including fish [ 37 , 38 ]. Shaw et al [ 7 ] reported 85% mortality of rainbow trout in 100 μ g Cu L −1 as CuSO 4 and 14% mortality in 100 μ g Cu L −1 as Cu-NPs after 4 days.…”

Copper nanoparticles (Cu-NPs) are components in numerous commercial products, but little is known about their potential hazard in the marine environments. In this study the effects of Cu-NPs and soluble Cu on juvenile Epinephelus coioides were investigated. The fish were exposed in triplicate to control, 20 or 100 µg Cu L−1 as either copper sulphate (CuSO4) or Cu-NPs for 25 days. The growth performance decreased with increasing CuSO4 or Cu-NPs dose, more so in the CuSO4 than Cu-NPs treatment. Both forms of Cu exposure inhibited activities of digestive enzymes (protease, amylase, and lipase) found in liver, stomach, and intestine. With an increase in CuSO4 and Cu-NPs dose, crude protein and crude lipid decreased, but ash and moisture increased, more so in the CuSO4 than Cu-NPs treatment. The Cu-NPs treatment caused pathologies in liver and gills, and the kinds of pathologies were broadly of the same type as with CuSO4. With an increase in CuSO4 or Cu-NPs dose, the total polyunsaturated fatty acids decreased, but total monounsaturated fatty acids and total saturated fatty acids increased compared to control. Overall, these data showed that Cu-NPs had a similar type of toxic effects as CuSO4, but soluble Cu was more toxic than Cu-NPs.

“…Apart from these species, a high extent of genetic isolation is characteristic of the only species, the Siberian round whitefish Prosopium cylin draceum, which is isolated in a separate genus in the family Coregonidae and shows no intercrosses with other species. The separation of the genus Prosopium from the other cluster is even more distinct on a UPGMA tree [14].…”

Repetitive DNA sequences as an indicator of the level of genetic isolation in fish

Although the functional role is still unknown for most types of nuclear noncoding repetitive sequences, some of them proved to provide adequate phylogenetic and taxonomic markers for studying the genetic relationships of organisms at the species and within species levels. Several markers were used in this work. First, microsatellite markers were used to examine populations varying in the extent of genetic subdi vision in marine and anadromous fish, including the Chilean jack mackerel Trachurus murphyi, anadromous brown trout Salmo trutta, and isolated and anadromous char populations. Locus polymorphism was propor tional to the gene flow between populations in all cases. Second, satellite DNA was used to study the phylo genetic relationships within the genera Salmo, Oncorhynchus, Salvelinus, and Coregonus. Genetic distances agreed well with the taxonomic relationships based on morphological traits and various biochemical markers and correlated with the evolutionary ages estimated for the groups by other markers. Third, RAPD PCR with a set of 20 mer primers was performed to study the genus Coregonus and anadromous and isolated popula tions and species of the genus Salvelinus. The resulting phylogenetic trees may help to resolve some disputable taxonomic issues for the groups. A comparison showed that several RAPD detected sequences contain con served fragments of coding sequences and polymorphic repeats (minisatellites) from intergenic regions or introns. The finding point to a nonrandom nature of repetitive DNA divergence and may reflect the evolution of the fish groups examined. Heterochromatic satellite repeats were assumed to contribute to generating a reproductive barrier.
