Increasing fishing pressure and uncertainty surrounding recreational fishing catch and effort data promoted the development of alternative methods for conducting fisheries research. A pilot investigation was undertaken to engage the Australian game fishing community and promote the non-lethal collection of tissue samples from the black marlin Istiompax indica, a valuable recreational-only speci...
This manuscript evaluates the U.S. Recreational Water Quality Criteria (RWQC) of 2012, based upon discussions during a conference held 11-13 March 2013, in Honolulu, Hawaii. The RWQC of 2012 did not meet expectations among the research community because key recommended studies were not completed, new data to assess risks to bathers exposed to non-point sources of fecal indicator bacteria (FIB) ...
Recreational waters should be considered as risks for Enterococcal infections in regions with high utilization and long exposure periods. The aim of this study was to investigate the resistance of Enterococci to selected antibiotics and some heavy metals [Pb+2, Fe+2, Zn+2 and Cr+2]. A total of 75 Enterococcal isolates was obtained from 54 bathing and ...
The use of enterococci as the primary fecal indicator bacteria (FIB) for the determination of recreational water safety has been questioned, particularly in sub/tropical marine waters without known point sources of sewage. Alternative FIB (such as the Bacteroidales group) and alternative measurement methods (such as rapid molecular testing) have been proposed to supplement or replace current ma...
Human exploitation of fi sh and other aquatic animals such as crustaceans and mammals is virtually ubiquitous on Earth and since ancient times has provided humanity with food, income and other social goods such as recreation. Fishing where the primary objective is not to produce food or generate income through the sale or trade of fi shing products is commonly termed ‘recreational fi shing’ or ...
Nonpoint, or diffuse, sources of water pollution include urban sources such as runoff from residential, commercial, industrial, transportation, and recreational land uses; construction activities; and onsite sewage disposal systems and rural sources such as runoff from cropland, pasture, and woodland, atmospheric contributions, and livestock wastes. These sources of pollutants discharge to surf...
ECONOMIC VALUE OF QUALITY IN WATER THE original abundance of water in the state of New York its very commonness, has dulled her people's appreciation of the subtle qualit;y value of their heritage. M\Iomentarily shut off from their supply the cities and industr-ies would instantly realize its vital necessity. Precipitate ruin of the wonderfully rich, living waters of the state would awaken imme...
BACKGROUND Geothermal waters could be suitable niches for thermophilic free living amoebae including Naegleria and Hartmannella. Ardebil Province, northwest Iran is popular for having many hot springs for recreational and health purposes activity. The present research is the first molecular based investigation regarding the presence of Naegleria and Hartmannella in the hot springs of Ardebil Pr...
