Bangor Naval Submarine Base, on the Hood Canal in the State of Washington, provides fine recreational facilities for service people stationed there, as well as for civilian employees. A proposal to divert runoff from munitions-contaminated areas towards the recreational fishing pond, Cattail Lake, led to a decision to identify hazard levels for the compounds of interest. In addition to trout, there was concern over contamination of bivalves, such as oysters, cockles, and clams, at the pond s outlet to Hood Canal. Bioconcentration factors (BCFs), assumed applicable for both fish and bivalves, were developed for three compounds (Table III). BCFs, together with Uj. values and worst-case levels of fish or bivalve consumption (0.4 kg/day) provided PPLVs for the pond water, according to the equation...

Biological. Algae isolated from a stagnant fish pond degraded 24.4% of the applied endrin to ketoendrin (Patil et al., 1972). Microbial degradation of endrin in soil formed several ketones and aldehydes of which ketoendrin was the only metabolite identified (Kearney and Kaufman, 1976). In four successive 7-d incubation periods, endrin (5 and 10 mg/L) was recalcitrant to degradation in a settled domestic wastewater inoculum (Tabak et al., 1981).

You have a fish pond on your property that s a perfect circle with a diameter of 100 feet. In the exact center of your fish pond, there s a flagpole. You want to tie a rope to that flagpole, but your rope is only 101 feet long, and you don t... 

Vegetation in fish ponds may be controlled by treatment with white arsenic or commercial sodium arsenite if applied in concentrations of 1 to 2 parts As203 per million.3 Several applications each year may be needed. Under these conditions the natural fish foods are uninjured and small fish are not adversely affected. Hard waters require a somewhat higher concentration of arsenic. The latter disappears rapidly from the waters, probably owing to precipitation.

A large source of water for reuse may be obtained by reclaiming polluted water. Sources of polluted water emanate from domestic wastewater, industrial waste solutions, agricultural effluent as runoff water, recirculated greenhouse water, and fish pond waste. All these must be treated to a tolerable quality to prevent deterioration of the soil and aquifers, and pollution of lakes, rivers, and the sea. Above all, this is a source of usable water.

Fresh-water fish have disappeared from many lakes and fish-ponds in Scandinavia and Canada, causing serious economic loss. The first to disappear, due to their greater susceptibility, are the salmonids. So, for example, in the south of Norway where there is high acid precipitation whereas the neutralizing action of the soil is poor, about half of the lakes have lost their trout population. In an area of 13,000 km almost all the lakes have lost their fish. In another further area of 20,000 km the number of fish has been drastically reduced and they will soon disappear altogether. Between Telemark and Lista there are 14...

Mortalities of fish have been reported for cyanobacterial blooms in earthen fish ponds and experiments have shown that microcystins were involved, indicating that cyanotoxins may enter the food chain throngh fish farming (Kaya, 2005). In addition, in a fishpond in Wuhan, China, the cyanobacterium, Raphidiopsis curvata was found to produce the hepatotoxins, cylindrospermopsin at 0.56 pg/g and deoxycylindrospermopsin at 1.3 mg/g (Carmichael et al., 2001). 

The toxin production of the prymnesiophyte Prymnesium parvum has been known for 60 years it has been shown that the alga excreted the toxin extracel-lularly [151-152]. The alga has caused fish deaths in brackish fish ponds and other brackish habitats and lately in a large marine fjord system [153]. 

My introduction to the field of chemical mediation in crustaceans is yet another example of the importance of individual mentors. My early interest in zoology began with my observations of all sorts of animals in my family s ornamental fish ponds. My first formal exposure to marine biology was in my high school biology class with additional training in the extracurricular marine biology club.

The main environmental problems are due to the low quality peat. The drained peat is vulnerable to fires in the summer. Farmers are unable to control soil humidity in a way that enables raising crops on the one hand, but avoids soil decomposition on the other hand. Often, decomposed soil is removed by the wind or washed to the Lake of Galilee. As time passes, the valley is sinking, to a degree that has caused concern that the swamp will return. Fishing ponds and a second lake were later built in order to reduce this risk (Alon, 1996 Goren, 1995 Shacham, 1994). The current conclusion is that, unfortunately, the warnings of the experts proved to be accurate and the benefits of the project proved to be minimal.
