“…Despite the rich species diversity of Clarias , a few species ( C. batrachus , C. gariepinus , and C. macrocephalus ) have been repeatedly studied from different biological and ecological perspectives [ 10 , 11 ]. Further, the North African catfish, C. gariepinus , has been used extensively for decades in aquaculture both within and outside its native range in South and Southeast Asian countries (Bangladesh, China, India, Indonesia, Malaysia, Myanmar, North Korea, Philippines, and Thailand), and this great success of aquaculture in tropical countries suggests that this species can be used for cross-breeding with other clariid catfishes [ 12 , 13 , 14 , 15 ].…”

The mitogenome of an endemic catfish Clarias camerunensis was determined from the Cameroon water. This circular mitogenome was 16,511 bp in length and comprised 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and a single AT-rich control region. The heavy strand accommodates 28 genes, whereas the light strand is constituted by ND6 and eight transfer RNA (tRNA) genes. The C. camerunensis mitochondrial genome is AT biased (56.89%), as showcased in other Clarias species. The comparative analyses revealed that most of the Clarias species have 6 overlapping and 11 intergenic spacer regions. Most of the PCGs were initiated and terminated with the ATG start codon and TAA stop codon, respectively. The tRNAs of C. camerunensis folded into the distinctive cloverleaf secondary structure, except trnS1. The placement of the conserved domains in the control region was similar in all the Clarias species with highly variable nucleotides in CSB-I. Both maximum likelihood and Bayesian-based matrilineal phylogenies distinctly separated all Clarias species into five clades on the basis of their known distributions (South China, Sundaland, Indochina, India, and Africa). The TimeTree analysis revealed that the two major clades (Indo-Africa and Asia) of Clarias species might have diverged during the Paleogene (≈28.66 MYA). Our findings revealed the separation of Indian species (C. dussumieri) and African species (C. camerunensis and Clarias gariepinus) took place during the Paleogene, as well as the South Chinese species (Clarias fuscus) and Sundaland species (Clarias batrachus) splits from the Indochinese species (Clarias macrocephalus) during the Neogene through independent colonization. This pattern of biotic relationships highlights the influence of topography and geological events in determining the evolutionary history of Clarias species. The enrichment of mitogenomic data and multiple nuclear loci from their native range or type locality will confirm the true diversification of Clarias species in African and Asian countries.

“…The extent of organ damage was in a time-and dose-dependent manner, with longer duration and larger dosages and causing fusion between adjacent lamellae, maximizing the oxygen diffusion distance between blood and water [41] . Furthermore, the area available for gas exchange is substantially reduced due to the fusion of the respiratory epithelia, resulting in hypoxia and stress [42] . The preceding actions harm the physiology of fish, resulting in death.…”

Acute Toxicity of Epigallocatechin Gallate and C-Phycocyanin in ZebrafishEpigallocatechin gallate and C-phycocyanin are natural food supplements, gaining a lot of popularity in biomedical researches. The lethal concentration 50 value for the zebrafish model was determined using a 96 h semi-static acute toxicity test. Zebrafish were transferred into a 1 l water tank starting with a minimal dose of 8 mg of epigallocatechin gallate and 1 g of C-phycocyanin, which further increased to the concentration of 30 mg for epigallocatechin gallate and 5 g for C-phycocyanin. Lethal concentration 50 of epigallocatechin gallate and C-phycocyanin was calculated to be 21.37 mg/l and 2.45 g/l respectively at 96 h in the zebrafish model. At high doses above 12 mg of epigallocatechin gallate and 1 g of C-phycocyanin, the test fish displayed various behavior responses like erratic and jerky swimming, attempts to jump out of the water, frequent surfacing and swallowing of air, normal skin color change, decreased opercular movement and finally leading to death. Histological observations showed hypertrophy, atrophy and vacuolar degeneration in the liver whereas tubular degeneration, glomerular hyper cellularity, dilation of Bowman's space, hemorrhage, and necrosis were observed in the kidneys exposed to the high doses of epigallocatechin gallate and C-phycocyanin treated fish. The gills of the test animals also expressed lamellar synechiae, hyperplasia, curling of lamellae, mucus secretion and shortening of the secondary lamella. The results demonstrated that doses above 30 mg/l and 5 g/l in the case of epigallocatechin gallate and C-phycocyanin respectively gave 100 % mortality and expressed organ-specific toxicity. Overall results revealed that exposure to high concentrations of epigallocatechin gallate and C-phycocyanin uninterruptedly may lead to severe alterations in the tissue of experimental animals.

“…Coal mine effluents contain acid, alkaline, and metal mine drainage from abandoned mines or produced during mine operations [17]. Their anthropogenic discharge, extension, and accumulation can cause the large-scale destruction of surface waters and aquatic ecosystems [18,19]. They are one of the more important factors causing a significant loss of biodiversity in the biota.…”

Coal mining activity contributes to energy security and employment occupation, but is associated with environmental deterioration. Coal combustion leads to GHG emissions, while coal mining results in the generation of saline effluents. These effluents are discharged in inland surface waters, applying significant pressure on their quality, with a negative impact on aquatic life and the economy of a region. This study includes water samples that were analyzed in order to investigate the organic compounds, heavy metals, and other physicochemical parameters. Biological monitoring was done according to the Water Framework Directive methodology. The results from an aquatic area in Southern Poland, which indirectly receives coal mine effluents, indicate elevated salinity with excessive chlorides, sulfates, and sodium ions. The water quality of another non-polluted aquatic area was also assessed to examine the impact of indirect coal mine wastewater discharge on this area. The high salinity levels hinder the use of river water for drinking, agricultural, or industrial purposes. The results obtained show high pressure on the ecological status of streams and rivers that receive mine effluents, and on the density and diversity of aquatic invertebrates. This pressure is clearly visible in the structure of benthic communities and in invertebrate diversity. It also contributes to the appearance of invasive species and increasing water salinity. Limiting discharges of mine water transporting large loads of saline substances would reduce the negative impact on the quality of river waters and biological life.
