Commercial and recreational fisheries managers often develop catch and effort estimates from information gathered in location or on-site surveys. However, a limited on-site sample cannot produce unbiased estimates of fishing effort or socioeconomic traits of the anglers unless weighting procedures are adopted to account for the varying frequencies of fishing of the fishermen. The corrective procedure involves establishing the relative probability of capturing a fisherman in the sample, then weighting the number of contacts with anglers in each frequency of use category. Unless information on the probability of including particular fishermen and fishing vessels in the sample is available the sample must be drawn with replacement.

Microbiological Aspects

This paper firstly reviews the microbiological aspects of the accumulation of xenobiotic and non-xenobiotic substances from industrial and domestic waste water treatments, with particular reference to hydrocarbons, pesticides and inorganic plant nutrients. The paper goes on to argue that if water bodies are to be used to establish recreational fisheries as well as for water supply and effluent disposal, then the management aim may need to be one of controlled eutrophy. Ramifications of this proposal are considered. The biological aspects of the impact of other recreational and amenity uses of water bodies on water and environmental quality is briefly described. The paper concludes by discussing the training required by potential water managers.
