Strategy of recreational anglers and estimated eel (Anguilla anguilla) catches in a large European catchment basin, the Loire (France)

The European Council Regulation (18 September 2007) for the recovery of eel stocks required European states to report on eel stocks and anthropic mortalities. The data sources for France reveal gaps in our knowledge about angling in the public domain, and catches from privately-owned rivers. We tested a simple method, using a survey, for estimating the strategy employed and the catches landed b...

Valuing a change in a fishing site without collecting characteristics data on all fishing sites: a complete but minimal model

Resource economists are often asked to value a proposed change at one, and only one, recreational site; the model we develop and estimate is applicable for those cases. The application is valuing the elimination of fish-consumption advisories on a large bay on Lake Michigan. The model is a minimal but complete: complete in that the choice set is not restricted, minimal in that only two conditio...

Gaussian Quadrature versus Simulation for the Estimation of Random Parameters: Some Evidence from Stated-Preference Choice Data

In environmental economics, numerical simulation using random draws is the method most commonly used to estimate joint probabilities of individual choices in discrete-choice, random-parameters models. This paper compares simulation to another method of estimation, Gaussian quadrature, on the basis of speed and accuracy. The comparison is done using stated preference data consisting of the answe...

Exploration of fishing gear and fisheries diversity of Agunmukha River at Galachipa Upazila in Patuakhali District of Bangladesh

Agunmukha River is an important water body having plentiful aquatic resources. The fisheries communities in the river are familiar with a diverse range of fishing gear and crafts to catch fish. Therefore, the objectives of the present study were to explore fishing gear and fishing crafts, catch composition of the respective gearand identification of fish biodiversity of Agunmukha River. A step ...

Study on the fishing performance of an alternative tubular-type pot for the common octopus, Octopus minor, in Korean coastal waters

We aimed to develop alternative fishing gear for catching the common octopus, to decrease the use of bait and operating costs in comparison to commercial net pots. A tubular-type pot was designed, and behavioral responses of the common octopus were experimentally monitored in tank and replicated 10 times to compare fishing performances between 300 experimental and 300 commercial net pots in the...
