    321 CMR: DIVISION OF FISHERIES AND WILDLIFE 321 CMR 5.00: COLDWATER FISH RESOURCES Section 5.01: Introduction and Purpose 5.02: Definitions 5.03: Criteria and Procedure for Designating Coldwater Fish Resources 5.04: Requests that the Division Evaluate the CFR Status of a Waterbody 5.01: Introduction and Purpose Certain species of fish are sensitive to increases in temperature and require coldwater to fulfill one or more of their life stage requirements. Since the 1940's, the Division has documented the presence of coldwater fish resources (CFRs) in the Commonwealth where these fish occur. In the 1990's, the Division established a list of CFRs to facilitate the tracking and effective monitoring, management and protection of these resources by the Division, other state agencies, and local regulatory authorities, including conservation commissions and planning boards. Under the Department of Environmental Protection's Water Management Act regulations at 310 CMR 36.00: Massachusetts Water Resources Management Program, an applicant proposing a water withdrawal that may affect a CFR designated by the Division pursuant to 321 CMR 5.00 will be required to minimize any impact on the CFR. The Division has not assessed all of the waterbodies in the Commonwealth to determine their status as a CFR. 321 CMR 5.00 codifies the criteria, procedures and related definitions used by the Division to designate waterbodies as CFRs. 321 CMR 5.00 also provides notice of where the Division's current list of CFRs is available for review by regulatory authorities

  • The Fish Communities of the Toronto Waterfront: Summary and Assessment 1989 - 2005
    THE FISH COMMUNITIES OF THE TORONTO WATERFRONT: SUMMARY AND ASSESSMENT 1989 - 2005 SEPTEMBER 2008 ACKNOWLEDGMENTS The authors wish to thank the many technical staff, past and present, of the Toronto and Region Conservation Authority and Ministry of Natural Resources who diligently collected electrofishing data for the past 16 years. The completion of this report was aided by the Canada Ontario Agreement (COA). 1 Jason P. Dietrich, 1 Allison M. Hennyey, 1 Rick Portiss, 1 Gord MacPherson, 1 Kelly Montgomery and 2 Bruce J. Morrison 1 Toronto and Region Conservation Authority, 5 Shoreham Drive, Downsview, ON, M3N 1S4, Canada 2 Ontario Ministry of Natural Resources, Lake Ontario Fisheries Management Unit, Glenora Fisheries Station, Picton, ON, K0K 2T0, Canada © Toronto and Region Conservation 2008 ABSTRACT Fish community metrics collected for 16 years (1989 — 2005), using standardized electrofishing methods, throughout the greater Toronto region waterfront, were analyzed to ascertain the current state of the fish community with respect to past conditions. Results that continue to indicate a degraded or further degrading environment include an overall reduction in fish abundance, a high composition of benthivores, an increase in invasive species, an increase in generalist species biomass, yet a decrease in specialist species biomass, and a decrease in cool water Electrofishing in the Toronto Harbour thermal guild species biomass in embayments. Results that may indicate a change in a positive community health direction include no significant changes to species richness, a marked increase in diversity in embayments, a decline in non-native species in embayments and open coasts (despite the invasion of round goby), a recent increase in native species biomass, fluctuating native piscivore dynamics, increased walleye abundance, and a reduction in the proportion of degradation tolerant species.

  • Piscine Mycobacteriosis
    Piscine Importance The genus Mycobacterium contains more than 150 species, including the obligate Mycobacteriosis pathogens that cause tuberculosis in mammals as well as environmental saprophytes that occasionally cause opportunistic infections. At least 20 species are known to Fish Tuberculosis, cause mycobacteriosis in fish. They include Mycobacterium marinum, some of its close relatives (e.g., M. shottsii, M. pseudoshottsii), common environmental Piscine Tuberculosis, organisms such as M. fortuitum, M. chelonae, M. abscessus and M. gordonae, and Swimming Pool Granuloma, less well characterized species such as M. salmoniphilum and M. haemophilum, Fish Tank Granuloma, among others. Piscine mycobacteriosis, which has a range of outcomes from Fish Handler’s Disease, subclinical infection to death, affects a wide variety of freshwater and marine fish. It Fish Handler’s Nodules has often been reported from aquariums, research laboratories and fish farms, but outbreaks also occur in free-living fish. The same organisms sometimes affect other vertebrates including people. Human infections acquired from fish are most often Last Updated: November 2020 characterized by skin lesions of varying severity, which occasionally spread to underlying joints and tendons. Some lesions may be difficult to cure, especially in those who are immunocompromised. Etiology Mycobacteriosis is caused by members of the genus Mycobacterium, which are Gram-positive, acid fast, pleomorphic rods in the family Mycobacteriaceae and order Actinomycetales. This genus is traditionally divided into two groups: the members of the Mycobacterium tuberculosis complex (e.g., M. tuberculosis, M. bovis, M. caprae, M. pinnipedii), which cause tuberculosis in mammals, and the nontuberculous mycobacteria. The organisms in the latter group include environmental saprophytes, which sometimes cause opportunistic infections, and other species such as M.

  • Major Challenges Through the Transforming Coldwater Fisheries in India
    Journal of Coldwater Fisheries 1(1):1-3, 2018 Major challenges through the transforming coldwater fisheries in India A K SINGH National Bureau of Fish Genetic Resources, Canal Ring Road, P.O. Dilkusha, Lucknow-226002 (Uttar Pradesh) E-mail:[email protected] ABSTRACT Himalayan River systems in India comprises of the Indus, the Ganges and the Brahmaputra being distinct entities harbouring precious ichthyofaunal diversity. The Schizothoracines are important dominant fishery of these river systems followed by cyprinids while there are numerous small fish species having ornamental value. Unfortunately, the fishery of Himalaya is suffering from anthropogenic stresses, physical barriers in the form of damming and hydropower projects and resulting habitat loss. Since societal development, climate change and ecosystem degradations are stemming into big threats to the natural aquatic resources and their fish germplasm, scientists and policy makers are facing several challenges for sustainable management of the aquatic germplasm resources and aquaculture production enhancement: Keywords: Fishery resources, Sustainable development, Aquaculture diversification; Recreational fishery; Policy framework Development of sustainable fishery resources regulatory measures and public awareness and sensitization (Singh & Akhtar, 2015, Singh & Sarma, 2017; Singh, 2018).

  • Fish Fauna of River Ujh, an Important Tributary of the River Ravi, District Kathua, Jammu
    Environment Conservation Journal 16 (1&2)81-86, 2015 ISSN 0972-3099 (Print) 2278-5124 (Online) Abstracted and Indexed Fish fauna of river Ujh, an important tributary of the river Ravi, District Kathua, Jammu V. Rathore and S. P. S. Dutta Received:16.03.2015 Accepted:18.05.2015 Abstract Fish survey of river Ujh, an important clean water tributary of the river Ravi, in Kathua district, has revealed the presence of 42 fish species belonging to 5 orders, 10 families and 27 genera. Fish fauna is dominated by Cypriniformes (27 species), followed by Siluriformes (10 species), Synbranchiformes (2 species), Perciformes (2 species) and Beloniformes (1 species). Fishing methods commonly employed include cast net, rod and hook, pocket net, poisoning, hand picking, stick, sickle and simple cloth. Fish diversity is fast depleting due to over exploitation, illegal fishing methods and fishing during breeding season. There are great prospects of increasing fish production in this river by stocking various carps in seasonal Ujh barrage at village Jasrota. Keywords: Fish fauna, river, fish diversity Introduction Riverine fish resources are fast depleting due to passes through narrow valley, deepens more and lack of fish resource information and over more to assume the character of gorge. Further exploitation. Sustainable exploitation of water bodies require detailed analysis of fish fauna down, at Panjtirthi, the valley widens and four inhabiting lotic waters and scientific streams viz. Bhini, Dangara, Sutar and Talin join management through regular monitoring and the Ujh. The Bhini is perennial and the remaining proper check on fishing pressure, including three streams are seasonal.It ultimately joins the unscientific fishing methods.

    Coldwater Fish Diversity of India and Its Sustainable Development A. K. Singh* and M. S. Akhtar ICAR-Directorate of Coldwater Fisheries Research, Bhimtal-263136, Nainital, Uttarakhand *Email: [email protected] Introduction India is one of the mega biodiversity hotspots in the world and occupies the 9th position in terms of freshwater mega biodiversity (Mittermeier et al., 1997). Biodiversity is essential for stabilization of ecosystems, protection of overall environmental quality, for understanding intrinsic worth of all species on the earth (Ehrlich and Wilson, 1991). The country is bestowed with vast and varied coldwater/hill fishery resources which are spread over the Himalayan and peninsular regions as upland rivers, streams, high and low altitude natural lakes and reservoirs. There are around Fig. 1 : Number of species present in the North-East India 8,243 km long streams and rivers, 20,500 ha (Ali, 2010) natural lakes, 50,000 ha of reservoirs, both natural and manmade, and 2500 ha brackish water lakes in central Himalaya and 91 from the Deccan plateau the high altitude (Mahanta & Sarma, 2010).

An experiment was performed in an outdoor large-scale mesocosm three times from 2011 to 2012 by comparing the responses to adjustment as a function of the volume of JFS in the control and experimental groups. Analysis results of the environmental monitoring over three periods indicated only minor differences in the physicochemical characteristics of the water quality and phyto- and zoo-plankton biomass, thereby enabling a comparative analysis of the feeding ecology. However, the water temperature exhibited large fluctuations, ranging from 16.4 to 27.6 ◦C, and high water temperature conditions (Period 1, 25.6 ± 2.0 ◦C) enhanced the predation activity of the piscivorous fish Coreoperca herzi (C.
