“…Fishery management is a dependent field, and in order to implement management plans and conservation actions, concrete data on demography parameters (growth and mortality rates), status of populations (stock assessments), and number of fish harvested (exploitation levels and rates) is the primary requirement (Raghavan et al, , 2013(Raghavan et al, , 2018a. Nonetheless, such data are readily available and confined to a few of the large-growing tropical cyprinids such as the members of the genus Tor (Bhat, Nautiyal, & Singh, 2000;Raghavan et al, 2011Raghavan et al, , 2018a, with complete absence of information available on other groups, including P. khavalchor which is presently categorized as the data-deficient species with possible speculation of its loss in the near future (Dahanukar, 2011;Dahanukar et al, 2012;IUCN, 2018;Menon, 1999). In this regard, the detailed investigation of the population dynamics of the data-deficient species inhabiting the Western Ghats of India is the key solution for imposing the conservation action plans.…”

“…The catfish genus Pachypterus consists of three species viz. Pachypterus acutirostris (Day, 1870) distributed in Irrawaddy, Sittang, and Bago rivers, Myanmar (Eschmeyer, Fricke, & van der Laan, 2018;Kottelat, 2013); Pachypterus atherinoides (Bloch, 1794) distributed in river drainages of the Indian subcontinent north of the Cauvery, Bangladesh, Nepal, and Pakistan (Ahamed et al, 2018;Buragohain, 2018;Eschmeyer et al, 2018); and Pachypterus khavalchor (Kulkarni, 1952) which inhabits the Krishna River basin of Peninsular India (Dahanukar, Paingankar, Raut, & Kharat, 2012;Eschmeyer et al, 2018). Each of these species is extremely delicious and having good market demands in their distribution range and thus provides dietary and financial advantage to the local community (Buragohain, 2018;Gosavi, Kharat, Kumkar, & Navarange, 2018;Kumbar & Lad, 2014).…”

“…Menon (2004) and Molur et al (2011) further suggested that it could be a threatened species due to its fragmented population and non-availability of population data. As a result, presently, P. khavalchor is categorized as the "data deficient" species by IUCN (Dahanukar, 2011;Dahanukar et al, 2012;IUCN, 2018). However, despite of the variety of threats operating on the P. khavalchor presently, no conservation action plans are specifically directed towards conservation of this species.…”

Background: The Western Ghats of India, one of the global biodiversity hotspots and freshwater eco-regions, harbors several fish species which not just form the important part of the world's freshwater biodiversity yet in addition are the vital segment of livelihood of the neighborhood population. The rate of fish decline in the Western Ghats is alarming. The absence of organized study and data scarcity on basic biology and life history traits of several species could be one reason behind the decline, and thus it is difficult to execute conservation action/s. This is especially true, particularly for data-deficient species for which definite data related to distribution, population size, and trend is not available. The present study deals with the detailed investigation of population dynamics of catfish species, Pachypterus khavalchor, which is data-deficient species inhabiting the Western Ghats of India and forms an important component of freshwater inland fishery, providing nutritional and financial security to the local community. Methods: Specimens for the present study were collected monthly for a period of 1 year from the River Panchaganga and length-frequency data were analyzed using FiSAT II software. Results: Length-weight analysis of pooled (male + female) data suggested the fish exhibited higher exponent than expected under isometry, indicating the positive allometric growth of P. khavalchor in the Panchaganga River. The asymptotic length (L∞) and the growth rate (K) were estimated as 149.63 mm and 0.71 year −1 respectively. Potential longevity (t max ) and length at first capture (Lc) were estimated as 4.22 years and 73 mm respectively. The total (Z), natural (M), and fishing mortality (F) were estimated as 2.23 year −1 , 0.88 year −1 , and 1.35 year −1 respectively. The current exploitation rate (E cur = 0.60) was found to be almost 90% that gives the maximum relative yield per recruit (E max = 0.67). Recruitment pattern revealed two peaks, suggesting the fish have two spawning bouts each year. Conclusions: The stock of P. khavalchor in the Panchaganga River may be in near full exploitation under the current harvesting strategy, with a high chance of recruitment failure in the future. Additional studies on the reproductive biology of P. khavalchor would be particularly welcome for the imposition of the seasonal closure for effective conservation of stock.

“…Although, a few studies are available on diversity and conservation of freshwater fish fauna of Krishna River system at Satara District, Kharat et al (2012) reported six species of catfish, out of 51 species of freshwater fishes from Krishna River at Wai and Dhom reservoirs. Dahanukar et al (2012) reported 11 species of catfish, out of 57 species of freshwater fishes of Indrayani River, a tributary of Bhima River. Jadhav et al (2011) reported 10 species of catfish of a total 58 species, close to the present study area; their data is confined only to Koyna tributary which is a major tributary of Krishna, which joins it at Karad City.…”

“…Encroachment of hill slopes and river beds by informal settlements is also a result of migration of the poor from the nearby villages and other drought prone regions of the state. Exotic plantations due to city beautifying approaches are also changing the nature of the green cover by reducing the local biodiversity and thus leading to local extinction [30][31][32][33]. The changed nature of green cover and housing has already resulted in the drastic decline e.g., of the common house sparrow once seen commonly across the city.…”

Growing ‘Smart’? Urbanization Processes in the Pune Urban Agglomeration

Abstract:The Indian city of Pune witnessed rapid growth and deep transformation processes in the last three decades. This paper assesses past developments and recent structures and processes against the concept of urban sustainability. Following an overview of the historical development, the dimensions of sustainability are discussed separately, based on empirical findings. Urban growth puts enormous pressure on Pune's land and water resources, changing the ecology of the area. The increasing water demand of Pune's growing population competes with growing energy and water demands. An assessment of future climate change impacts indicates that the storage capacity of the reservoirs is more frequently not met during the rainy season. In addition, extreme dry years can aggravate the effects of land use change on water resources in the future. The city's growth and especially the large in-migration has also changed Pune's social fabric significantly. Wealth is distributed unevenly in the city and social disparities can be observed along two fault lines, namely along classes and caste groups. The population development and the increasing socioeconomic polarization are linked to the economic development of the city. Pune's formal economy has a robust base. However, as in many cities of the Global South, the informal economy is the most relevant source of income for large parts of the population. Pune's development is challenged by informality, poor infrastructure and inadequate planning and governance. Recently new approaches towards urban renewal and smart city development were launched. These new approaches aim at overcoming blockades in the traditional planning. A special challenge for urban planning is the transformation of urban fringe areas of the city, as this process is currently taking place in an unsustainable manner. The paper concludes that urban development has to become holistic, integrative and participative and should abandon the stereotype vision of the world class city in favor of a sustainable, locally adjusted pathway of development.
