two fresh water fishes

A study on stream morphology of some selected streams hill streams of district Nainital with special reference to its biotic communities. 2005;67:1266–79. Therefore, we recommended that the streams particularly large pools should be protected from excessive pumping for irrigational use and pollution because they can be used as a refuge, feeding and spawning sites of stream fishes. B. W. Coad and N. Najafpour, “Barbus sublimus, a New species of Cyprinid fish from Khuzestan Province, Iran,” Ichthyological Exploration of Freshwaters 7/3, 1997, pp. NT non-testable, NS non-significant, *significant at P < 0.05, **significant at P < 0.01. L. S. Berg, 1913. 2003). XX. Schlosser IJ, Ebel KK. Figure 7. 2018; in press. Fisheries. In addition, surface water temperature was varied from12.4 °C to 26.8 °C in Elala, 17 °C to 25.1 °C in Gereb Tsedo, and 19.3 °C to 26.7 °C during the study period. The quality and quantity of fish habitat in a water body directly affect fish populations. VIII-XIII. However, if you pick one or two breeds, make sure you have all their requirements put in place, so they will thrive in the new aquarium. The venom has both neurotoxic and haemotoxic components, and documented fatalities have occurred in India. The Shannon index of diversity was calculated as H’ = −Σpi ln (pi), where pi = ni/N; ni is the number of individuals of “ith” species and N = Σni. Riffles had significantly lower species richness between the streams than pools or runs (Fig. In addition, the streams did differ in the abundance of macroinvertebrate taxa, riparian cover, and waste dumping sites. 2003;60:849–63. 209–16. Knowledge and prediction of community characteristics in response to different environmental factors is one of the main objectives of community ecology. Only the loaches, the carps, and the minnows are found in all Persian basins. Fish Habitat Factsheet. We are here to introduce you to one of the most beautiful members of the group, the Texas Cichlid. However, we can safely say that key macroinvertebrate taxon affects fish abundance independently of stream type and habitat type. Gray arrows indicate the important variables as determined by forward selection in the redundancy analysis (Corixidae, Tabanidae, Lymnaeidae, Damselfly larvae, DO, velocity, transparency, depth). 1-20. Blue arrows represent fish community abundances. An overview of labeonin relationships and the phylogenetic placement of the Afro-Asian genus Garra Hamilton, 1922 (Teleostei:Cyprinidae), with the description of five new species of Garra from Ethiopia, and a key to all African species. According to variation partitioning, an RDA model based on the streams explained 25% of the variation (P < 0.01). Here, I have shared some of the most beautiful and colorful freshwater fishes in the world. Habitat selectivity and ecology of freshwater fishes were studied in two selected streams and their junction point which consist a total of 39 microhabitats. 6, pp. This fish needs various physiological adaptations to keep their bodies’ ion concentration balanced. 1 C). N. A. Dmitriev, “Kefal’ v iranskikh vodakh Kaspiya” (Mullet in the Iranian waters of the Caspian), Priroda 12, 1946, pp. The construction of dams, pollutants from industry and farming, poaching, and excessive commercial catches, have all contributed to a decline in their numbers. Negi RK, Negi T. Assemblage structure of stream fishes in the Kumaon Himalaya of Uttarakhand State, India. Understanding the ecology and stream habitats is of vital importance to ensure better water quality management and conservation activities. 2, Table 2). Hawkins CP, Kershner JL, Bisson PA, Bryant MD, Decker LM, Gregory SV, McCullough DA, Overton CK, Reeves GH, Steedman RJ, Young MK. Map of study area showing Mekelle City and the two study streams with their respective study sites indicated by yellow triangles labeled with their corresponding names (abbreviated) along the streams (Key: MW= May Weini, MTE= May Tsaeda Egam, CAS= Castle, MG=May Gifaf, K11= Kebele 11, GTS =Gereb Tsedo, E1= Elala1, E2= Elala 2, E3= Elala3, E4= Elala4, E5= Elala 5, E6= Elala 6, MD= Mariam Dahan). 16-19. In association with this commission, Major St. John made collections from 1869-71 with a collector from the Indian Museum, Calcutta. Influence of drainage connectivity, drainage area and regional species richness on fishes of the interior highlands in Arkansas. SFCC. These include the herring (Tenualosa ilisha; Figure 6), the milkfish (Chanos chanos), the tooth-carp (Aphanius dispar; Figure 7), three goby species, and possibly the mullet (Liza abu; Figure 8). Minnow (Capoeta damascina). The bitterling, Rhodeus amarus (Figure 2), is particularly colorful in the spawning season when males have a bright red iris and iridescent violet and steel-blue flanks, the throat and belly are orange to blood-red, the dorsal and anal fins are bright red, margined with black, and the caudal fin is green at the base and yellow at the edge. The most important early work on the fishes of Persia is that of Jakob Heckel, inspector at the Imperial Royal Court Collection of Natural History in Vienna. Moreover, fish abundance increased with pool habitat type (P < 0.01) and with availability of key macroinvertebrate taxa (P < 0.01). Parasiewicz P. The MesoHABSIM model revisited. Exotics have been imported for food, aquaculture, sport, research, ornamentation, weed control, health reasons, or accidentally. The large and significant amount of variation explained by habitat type may indicate that habitat use is indeed potentially an important factor determining total fish abundance.

Ecological diversity and its measurement: Cambridge University Press; 1988. p. 179. Rostami). Overexploitation (unsustainable fishing) poses a serious threat to fish and aquatic biodiversity and also to the livelihoods of people in riverine and lake communities. Freshwater fish need to maintain their internal salinity. 581-84. Fame Consortium. Fish size and habitat depth relationship in a headwater stream. Freshwater makes up less than 3 percent of Earth’s water supply but almost half of all fish species live in rivers, lakes, ponds, and wetlands. William Thomas Blanford accompanied the Persian Boundary Commission in 1872, publishing a two-volume account in 1876, but fish collections were minor and were not included. The influence of habitat structure on fish assemblage composition in a southeastern black water streams. R Development Core Team. Also known as the Lace Gourami, this cool tropical freshwater fish is one of the most popular Gourami fish for aquarium lovers, thanks to its beautiful appearance and its hardy build. 1). B. W. Coad and A. Abdoli, “Exotic Fish Species in the Fresh Waters of Iran,” Zoology in the Middle East 9, 1993, pp. This article is available in print.Vol. To visually explore patterns of associations among habitats, streams, key environmental conditions, and between these variables and variation of fish species abundance and total abundances, principal component analysis (PCA) was used. 453-75, pl. Nelson Annandale, founder and director of the Zoological Survey of India, co-authored a review of the fishes of Sīstān with Sunder Lal Hora, based on specimens collected by the Seistan Arbitration Commission of 1901-4, and by officers of the Zoological Survey of India in the winter of 1918. The Cyprinidae are the commonest and most individually numerous fishes in qanāts (Coad, 1996f), springs, and small streams in the vast desert basins. Community indices, parameters and comparisons. 1988;23(3):215–24. 3). Based on this fish abundance, all pools support the highest fish abundance among the studied habitats of the streams and this might be due to its greatest depth which allows the fish species to get sufficient feed and refuge. 4). 69-79. The distribution of fishes in Persian freshwater basins is summarized in Table 2. Article  Species richness was calculated as the total number of species per site or habitat (Magurran 1988). Still other species are threatened because of their restricted habitat—a single event such as a chemical spill or a natural disaster could eliminate them. The sharks seize people who are bathing, swimming, washing clothes or vehicles, or fishing. His three-volume summary work on the freshwater fishes of the U.S.S.R. and adjacent countrieswas published in Russian in 1948-49 and in English translation in 1962-65. Photo about Two freshwater fishes in metal smokehouse. 163-72. Among the explanatory (environmental) variables, only a few of them were significantly cause a variation in fish abundance on the study streams (Table 4). In addition, macrophyte cover (%) was checked along the electrofishing areas (fish sampling trajectory in all sites of both streams). Figure 14. Purchase Freshwater Fishes - 1st Edition. Idem, “Range Extension for the Snakehead Ophiocephalus gachua Hamilton-Buchanan (Osteichthyes: Channidae) in Iran,” Journal of the Bombay Natural History Society 75/2 (1978), 1979b, pp. A number of freshwater fishes are potentially dangerous to man if the eggs are consumed, although there are no documented fatalities in Persia. 2006;45(1):114–23. 238-45. Version, 1; 2005. The Sīstān basin has large rivers and extensive marsh habitat, but is remote from the sea and from the centers of faunal diversity. Environ Biol Fish. 2007;88:1687–95. 51-80. a minnow (Capoeta damascina; Figure 5) is found in six basins. For the prediction of fish diversity and abundance, it was found that stream type, habitat type, and the availability of key macroinvertebrate taxa (food resources) were the best predictors for fish abundance and species richness, compared to physicochemical variables. 1985;66(5):1484–90. “Systematics of the Tooth-carp Genus Aphanius Nardo, 1827 (Actinopterygii: Cyprinodontidae) in Fars Province, Southern Iran,” Biologia (Bratislava) 51/2, 1996a, pp. P.

V. Nestorov, who worked with the Turko-Persian Demarcation Commission in 1914 and collected fishes in the Tigris basin along the present Persian-Iraq frontier. 1). Idem, “A Re-description of Aphanius ginaonis (Holly, 1929) from Southern Iran (Osteichthyes: Cyprinodontiformes),” Journal of Natural History 14/1, 1980c, pp. Macroinvertebrate field collections were also undertaken along with the fish sampling period 13 sites and 39 microhabitats (Fig. Freshwater ecosystem and its resources are an indispensable part of human life and activity. A higher total fish abundance was recorded from Gereb Tsedo (4870; 74.3%) than from Elala stream (1684; 25.7%). These are known as catadromous fish. Data of Gereb Tsedo (GTS) stream are represented by filled circles, Elala (ELA) by filled squares, and Mariam Dahan (MD), the common stream of the two streams below their junction, are indicated by filled diamonds. The aims of this study were to describe the habitat preference and its availability to fish assemblage, as well as ecology, habitat use, and habitat characteristics.
