“…Being an integral component of aquatic ecosystems, they have key role in energy flow, nutrient cycling and maintenance of community balance (Nelson, 2006;Kang et al, 2009). Freshwater fishes exhibit extraordinary taxonomic breadth, endemism and a wide range of geographic distribution (Leveque et al, 2005;Javed, 2015). The taxonomic diversity of freshwater fishes is revealed by the wide range of morphological, behavioral, and life history characteristics of the constituent species.…”

The current study investigated abundance, species richness and diversity of Ichthyofauna of hill torrents of Suleman Mountain, Range, Dera Ghazi Khan Region, Pakistan. Fish sampling was carried out from ten sites. The fishes were identified following standard taxonomic keys. Relative abundance (%) and diversity indices were calculated. One way analysis of variance (ANOVA) was used to compare the fish abundance and diversity at different sites. Twenty fish species belonging to five families were recorded. Cyprinidae was the richest family represented by sixteen fish species, demonstrating a significant dominance (P<0.05) in number of species over other families. Tor macrolepis was the most abundant species (20.87%). A significant difference (P<0.001) was observed for species abundance at various sites, with maximum abundance (21.11%) found at Hingloon. Similarly, a significant difference (P<0.001) was demonstrated for species richness between different sites, with maximum taxa number found at Barthi. The fish fauna was indigenous with three endemic species i.e. Barilius pakistanicus, Labeo dyocheilus pakistanicus and Salmophasia punjabensis. Diversity indices values did not indicate conclusive status about fish diversity of the region. Simpson diversity index indicate greater diversity, Shannon Weiner indicate moderate diversity and Margalef index indicate poor fish diversity of the region. The occurrence in wild of some high value commercial fishes indicates towards commercial fisheries potential of the area.

“…Nickel is a ubiquitous element obtained from natural resources and widely spread into the environment through anthropogenic activity. Reports on the adverse effect of lethal and high concentrations of Nickel are reported by [66], where fish species showed exploratory behaviour such as a decrease in appetite leading to significant growth retardation. Nickel exposure is said to induce some histological changes in the anatomy of Oreochromis niloticus.…”

Trace metals occur during natural processes and are also obtained during anthropogenic activities. Streams, lakes and rivers surrounded by farmlands engaged in the use of Trace metal-enriched fertilizers have shown a possible and positive correlation to the rise of Trace metals in the use of chemical, organic and water-soluble fertilizers for a long period. there is a tendency for high correlations of trace metals in source waters. Furthermore, the increasing level of trace metals in fish is alarming and has spurred scientists to make research on the dangers caused by the trace metals resulting in trace metal accumulation and bioaccumulation of life cells. This study aims at assessing the possible sources of trace metals in the aquatic environment, the impact of Trace metals in the aquatic environment, their bioaccumulation in fish and human health risk impact, negative effects in fish have been attributed to the accumulation of trace metals such as irritation of the gastrointestinal mucosa, nephritis, necrosis, neurological and behavioural disorders and death amongst others). The ingestion, absorption and uptake of trace metals in fish are usually toxic and result in harmful damage to the fish and fish life. Since most of the metals taken up are non-biodegradable, such metals can bioaccumulate and bio-magnify. Over time, the accumulated metals affect the growth and development stages of fish from the production of viable eggs, hatchability laval, fingerlings and juvenile life stages. This is so because the early life stages are more sensitive than during maturing and adulthood. In conclusion, negative results of the presence of trace metals and the effect of bioaccumulation and bio-magnification have been reviewed in this paper. This study recommends that the proper assessment and treatment of all forms of wastewater, agricultural waste, sewage, and industrial effluents be carried out before their discharge into the environment.
