A total of 671 specimens representing 7 genera and 10 species were collected. Species collected were Barilius pakistanicus, Barilius vagra, Tor putitora, Crossocheilus diplocheilus, Garra gotyla, Schizothorax labiatus, Schizothorax esocinus, Schizothorax plagiostmus, Carassius auratus and Cyprinus carpio. Schizothorax plagiostmus was found to be the most abundant species with a relative density (RD) of 21.01 and relative frequency (RF) of 13.04. It was the only species qualifying the criterion to be ranked as eury species. Schizothorax esocinus was rare in the study area with a RD 0.45 and RF 2.17.

    The status of the endangered freshwater fishes in China and The analysis of the endangered causes HE Shunping, CIIEN Yiyu Institute of Hydrobiology, CAS, Wuhan, ITubei Province, 430072 Abstract More than 800 species of freshwater fishes are precious biological resources in inland water system of China. Among them, there are a great number of endemic and precious group, and a lot of monotypic genera and species. Recently, owing to the synthetic effects of the natural and human-beings, many of these fishes gradually became endangered. The preliminary statistic result indicates that 92 species are endangered fishes and account for 10% of the total freshwater fishes in China. For the purpose of protection of the biodiversity of fishes, it is necessary to analyse these causes which have led the fishes to become endangered. This report could be used as a scientific reference for researching and saving the endemic precious freshwater fishes in China. Key words Endangered freshwater fishes, Endangered causes, China In the process of the evolution of living things, along with the origin of life, the extinction of life also existed. In the long_ life history, the speciation and the extinction of living things often keep a relative balance. As time goes on, especially after by the impact of human beings activity of production and life, the pattern of the biodiversity were changed or damaged, more or less. At last, in the modern society, human beings activity not only accelerate the progress of society and the development of economy, but also, as a special species, become the source of disturbing_ to other species.

After the death of Al-Mustansar Bi’llah, the caliph of Egypt, his descendants for four generations from Sultan Yasin to Shah Muzammil remained in Egypt. But Shah Muzammil’s son Sultan Ahmad II left the country between l366-70 in the reign of Abu al- Fath Mumtadid Bi’llah Abu Bakr, the sixth ‘Abbasid caliph of Egypt, 1 and came to Sind. 2 He was succeeded by his son, Abu Nasir, followed by Abu Qahir 3 and Amir Muhammad Channi. Channi was a very competent person. When Prince Murad Bakhsh, son of the Mughal emperor Akbar, came to Multan, 4 he appreciated his services, and awarded him the mansab of “Panj Hazari”5 and bestowed on him a large jagir .

  • Deforestation in the Princely State of Dir on the North-West Frontier and the Imperial Strategy of British India
    Central Asia Journal No. 86, Summer 2020 CONSERVATION OR IMPLICIT DESTRUCTION: DEFORESTATION IN THE PRINCELY STATE OF DIR ON THE NORTH-WEST FRONTIER AND THE IMPERIAL STRATEGY OF BRITISH INDIA Saeeda & Khalil ur Rehman Abstract The Czarist Empire during the nineteenth century emerged on the scene as a Eurasian colonial power challenging British supremacy, especially in Central Asia. The trans-continental Russian expansion and the ensuing influence were on the march as a result of the increase in the territory controlled by Imperial Russia. Inevitably, the Russian advances in the Caucasus and Central Asia were increasingly perceived by the British as a strategic threat to the interests of the British Indian Empire. These geo- political and geo-strategic developments enhanced the importance of Afghanistan in the British perception as a first line of defense against the advancing Russians and the threat of presumed invasion of British India. Moreover, a mix of these developments also had an impact on the British strategic perception that now viewed the defense of the North-West Frontier as a vital interest for the security of British India. The strategic imperative was to deter the Czarist Empire from having any direct contact with the conquered subjects, especially the North Indian Muslims. An operational expression of this policy gradually unfolded when the Princely State of Dir was loosely incorporated, but quite not settled, into the formal framework of the imperial structure of British India. The elements of this bilateral arrangement included the supply of arms and ammunition, subsidies and formal agreements regarding governance of the state. These agreements created enough time and space for the British to pursue colonial interests in Ph.D.

Accepted 17 February, 2012 Cytogenetic studies have helped in clarifying the problem of disagreement amongst taxonomists on the identity of a given species. Cytogenetic studies were performed on two fishes of the genus Schizothorax viz. Schizothorax curvifrons Heckel and Schizothorax niger Heckel (Cyprinidae: Schizothoracinae) obtained from Sindh Stream and Dal Lake Srinagar Kashmir, respectively. These fishes are considered to be the subspecies of the same species. The two species showed a diploid number of 98 in S. niger and 94 in S. curvifrons. The karyological data are analyzed in terms of the taxonomic aspects within this genus, and the validity of their existence as species chromosomally distinct from each other is emphasized.

Degree College, Oghi, Pakistan E-mail: [email protected] Received 12 August 2020; Accepted 20 September 2020; Published 1 December 2020 Abstract Ichthyofaunal composition is the most important and essential biotic component of an aquatic ecosystem. There is worldwide distribution of fresh water fishes. Pakistan is blessed with a diversity of fishes owing to streams, rivers, dams and ocean. In freshwater bodies of the country about 193 fish species were recorded. There are about 30 species of fish which are commercially exploited for good source of proteins and vitamins. The fish marketing has great socio economic value in the country. Unfortunately, fish fauna is declining at alarming rate due to water pollution, over fishing, pesticide use and other anthropogenic activities. Therefore, about 20 percent of fish population is threatened as endangered or extinct. All Mashers are ‘endangered’, notably Tor putitora, which is also included in the Red List Category of International Union for Conservation of Nature (IUCN) as Endangered. Mashers (Tor species) are distributed in Southeast Asian and Himalayan regions including trans-Himalayan countries like Pakistan and India. The heavy flood of July, 2010 resulted in the minimizing of Tor putitora species Khyber Pakhtunkhwa and the fish is now found extinct from river Swat.

  • Modeling the Efficacy of the Ganga Action Plan's Restoration of The
    Modeling the Efficacy of the Ganga Action Plan’s Restoration of the Ganga River, India By Shaw Lacy A thesis submitted In partial fulfillment of the requirements For the degree of Master of Science Natural Resources and Environment at The University of Michigan August 2006 Thesis Committee: Professor Michael Wiley Professor Jonathan Bulkley Abstract. To combat rising levels of water pollution in the Ganges River, the Indian gov- ernment initiated the Ganga Action Plan (GAP) in 1984. After twenty years, it is a com- mon perception that the GAP has failed to achieve the goals of a cleaner river. Using available government data on pollution levels and hydrology, I undertook an of the GAP efficacy for fifteen pollution parameters across 52 water quality sampling points moni- tored by India’s Central Pollution Control Board (CPCB) within the Ganga Basin. Dis- solved oxygen, BOD, and COD showed a significant improvement of water quality after twenty years. In addition, fecal and total coliform levels, as well as concentrations of cal- cium, magnesium, and TDS all showed a significant decline. Building on this analysis, a GIS analysis was used to create a spatial model of the majority of the Ganga River net- work using a reach-based ecological classification approach. Using recent GAP monitor- ing data, a multiple linear regression model of expected pollutant loads within each reach (VSEC unit) was created. This model was then used to inventory water quality across the entire basin, based on CPCB criteria. My analysis showed 208 river km were class A, 1,142 river km were class B, 684 river km were class C, 1,614 river km were class D, and 10,403 river km were class E.

The current work is design to highlight the facts, real causes and impacts of deforestation and forest degradation in P “Dir Kohistan” of K.P.K Pakistan, by incorporating the view of local people through a questionnaire. According to this survey about 83% of the local people are dependent on these forests and contribute to deforestation in one of different ways regardless of any rule regulation. The current study shows that the extensive deforestation in the mention area occurs for household needs (cooking, furniture, heating, earning etc). Another growing cause is the cutting of these forests for livestock purposes. Along this the nonscientific grazing is a key point in the deforestation. Unemployment and poverty is another attractive factor in the degradation of these forests. However the role of black marketing and role of stake holders on these forests should not be neglected in deforestation.
