Available in PDF, EPUB and Kindle. Book excerpt: The authoritative guide to understanding and managing the ecological impacts of recreational activities in wildlands This third edition provides an updated and thorough examination of the ecological impacts of recreational use on wildlands and the best management practices to employ in places where recreation and preservation of natural conditions are both important - and often conflicting - objectives. Covering the latest research, this edition provides detailed information about the environmental changes that result from recreational use. It describes spatial patterns of impact and trends over time, then explores the factors that determine magnitude of impact, including amount of use, type and behavior of use, and environmental durability. Numerous examples, drawn from parks and recreation areas around the world, give readers insight into why certain areas are more heavily damaged than others, and demonstrate the techniques available to mitigate damage. The book incorporates both the first-hand experience of the authors and an exhaustive review of the world’s literature on the subject. Boxes provide quick access to important material, and further resources are referenced in an extensive bibliography. Essential reading for all park and protected area management professionals, this book is also a useful textbook for upper division undergraduate and graduate students on recreation ecology and recreation management courses.

Download or read book Striped Bass and Other Morone Culture written by R.M. Harrell and published by Elsevier. This book was released on 1997-05-23 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an up-to-date discussion of the culture of striped bass and other Morone spp. The subject matter is broken down into functional components of the spawning, husbandry, and economics of the industry, and is written by some of the leading scientists in each of the respective areas of discussion. The chapters on reproduction, nutrition, environmental requirements, transportation, economics and fish processing are not found anywhere else in the striped bass literature. The chapter on water quality takes a very non-traditional approach to considering the impact water quality has on the production success of Morone and offers some very thought-provoking ideas on water management.Primarily written as a reference work, this book is intended to complement existing technique manuals.

This book was released on 1961 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were conducted to determine the effect of abrupt temperature and salinity changes on adult and juvenile striped bass (Roccus saxatilis) and American shad (Alosa sapidissima). Transfers were made at specific temperature and salinity differences over the range 45° to 80° F. and 0 to 35°/00. Adult and juvenile striped bass were tolerant to transfers between salt and fresh water at most temperature differences. Adult shad were tolerant to transfers from fresh to salt water and displayed some tolerance to transfers from salt to fresh water at limited temperature differences. Juvenile shad survived salinity and temperature differences from salt to fresh water, but did not survive these differences from fresh to salt water.

This book was released on 2019 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change projections estimate a 2-3°C increase in water temperatures by the end of the century. The amount of habitat with suitable temperature and oxygen concentration for aquatic organisms will also be reduced. Striped bass (Morone saxatilis) inhabiting the rivers in Southeastern Georgia make an interesting study system as they do not participate in summer coastal migrations typical of their northern conspecifics. Instead, fish in this southern population remain in freshwater environments that experience warming and decreases in dissolved oxygen. The present study aims to determine the thermal and low oxygen tolerance of juvenile striped bass collected from southeast Georgia through the measurement of aerobic metabolic scope (AMS), loss of equilibrium (LOEcrit), and critical oxygen tension (Pcrit). Fish were acclimated to one of four experimental temperatures (20, 25, 30, and 33°C), representing the range of temperatures typical of the natural environment in the summer as well as the anticipated increase in temperature due to climate change (33°C). Additionally, plasma samples were analyzed for lactate levels to assess the metabolic state of the fish. Results indicate fish acclimated to 30 and 33°C have reduced performance (lower AMS) and low oxygen tolerance (LOEcrit). The findings of this study determined that southern striped bass are susceptible to projected increases in temperature where an increase of 3°C will push them close to the thermal lethal limit and lower their ability to survive in hypoxic environments.

This book was released on 2007 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of field and laboratory studies were conducted from 1998--2005 to examine the relationship between nutritional status and mycobacteriosis in Chesapeake Bay striped bass (Morone saxatilis). A review of archived tissue blocks of wild striped bass collected from 1975--1995 revealed that this is not a new disease of the species. Application of genus specific PCR and multi-gene sequencing from 1984-1985 samples identified the species as one of the tuberculosis clade common in the current epizootic in Chesapeake Bay. Closest identity was found with the recently described M. pseudoshottsii . These findings, 13 years before the initial isolations from Chesapeake Bay fish, suggest that other factors may be relevant in enhancing an endemic disease to the current elevated prevalence (> 50% in age 3+ fish). Field surveys and feeding trials were conducted from 1998-1999 to determine the overall nutritional condition of striped bass and the association with disease state. Proximate composition revealed elevated moisture (~80%) and low storage lipids ( 0.5% ww), characteristic of a poorly nourished population. Wild collected fish (age 3 and 4) were not significantly different in chemical composition, weight at length, or mesenteric body fat than fish experimentally deprived of food for two months (p 0.05). These findings were not consistent with data collected in 1990-1991, or with experimentally fed fish used as benchmarks for this study. Mycobacteriosis explained little of the variance in chemical composition (p > 0.2); however elevated moisture and low lipid concentration were associated with fish with ulcerative lesions (p 0.05). This suggests that age 3 and 4 striped bass were in poor nutritional health in 1998-1999, which may be independent from the disease process. Based on these findings, challenge studies were performed to address the hypothesis that disease progression and severity may be altered by nutritional status of the host. Intraperitoneal inoculation of 104 colony forming units (CFU) M. marinum resulted in high mortality, elevated bacterial density, and poor granuloma formation in low ration (0.15% bw/d) groups while adequately fed fish (1% bw/d) followed a normal course of granulomatous inflammation with low associated mortality to a steady, equilibrium state. Further, we demonstrated that an active inflammatory state could be reactivated in fish through reductions in total diet. The energetic demand of mycobacteriosis, determined by tissue chemical composition, was insignificant in comparison to sham inoculated controls in adequately fed fish (p 0.05). Declines in total body energy were only apparent during active, inflammatory stages of disease. Overall, these findings suggest that: (1) mycobacteriosis is not a new disease of Chesapeake Bay striped bass, (2) the disease has little energetic demand in the normal, chronic progression, and (3) poor nutritional health can greatly enhance the progression and severity, and reactivation of disease. The implications of this research are that management strategies focused on enhancing the nutritional state of striped bass could potentially alter the disease dynamics in Chesapeake Bay.
