A Method of Estimating Fishing Pressure and Harvest as Used on Logan River, Utah

Regenthal, Albert Frank 01 May 1952 (has links)
Completely accurate statements of fishing pressure and harvest can only result from an ennumeration of all anglers and their catch. On most bodies of water it has not been economically feasible for management agencies to effect a complete census of fishermen and harvest. Practically, absolute accuracy is not necessary for management. The development of creel census methods resulting in estimates of known accuracy, yet requiring only a practical outlay of time and money, would be a step toward more effective management.

Analýza návštěvnosti revírů Českého rybářského svazu v rámci celosvazového rybolovu / Analysis of fishing pressure at sport fisheries managed by Czech Angling Union under the united fishing system.

ŠMÍD, Pavel January 2012 (has links)
The goal of the thesis was to analyse the fishing pressure, number of visits and number of catches in sport fisheries managed by Czech Angling Union (CAU). The selected data, mainly concerning the sport fisheries managed by South Bohemian Board of CAU, were graphically presented. At the trophy fishery Vltava 24, daily data were evaluated and the behaviour of fishermen was compared during the first two years of the new management (2010 and 2011). The second part of the thesis is aimed at the analysis of the united system of fishing management within the whole CAU and suggests a new system of financial flow. CAU is composed by 7 regional boards; however, it is possible to buy united fishing permit valid in all the fisheries of CAU. The financial budget coming from these permits is redistributed only according to the weight of killed and recorded fish. This system is advantageous mainly for regional boards with a big amount of fishermen and high fishing pressure at their fisheries; it is less advantageous for regional boards managing large areas. Within the thesis, a new model for redistribution of the financial budget was created. Except for the weight of killed fish, it includes other expenses connected with the management (fishing guards, lease of fishing waters, etc.) and the number of fishing visits. The model was provided to CAU for future negotiation.
