Catch-per-unit-effort: which estimator is best?
In this paper we examine the accuracy and precision of three indices of catch-per-unit-effort (CPUE). We carried out simulations, generating catch data according to six probability distributions (normal, Poisson, lognormal, gamma, delta and negative binomial), three variance structures (constant, proportional to effort and proportional to the squared effort) and their magnitudes (tail weight). ...
متن کاملMark-recapture and catch per unit effort measures of walleye (Sander vitreus) abundance in Otsego Lake, NY
In this study, the adult population of Otsego Lake walleye was estimated in order to evaluate the success of the walleye stocking program. Spawning walleye were trap netted at five locations in April 2008, marked with a dorsal fin punch and visible implant elastomer, and recaptured in May using boat electro-fishing and in September by NYSDEC experimental gill net survey. Catch per unit effort a...
متن کاملSpecies diversity and catch per unit effort (CPUE) of Gobiidae in Salmanshahr, coastal area of the southern Caspian Sea
The gobies are non-commercial fishes in the Iranian waters of the Caspian Sea for which population dynamics and stock status are poorly known. In this survey, we tried to define species diversity and catch per unit effort (CPUE) of Gobiidae by using beach seine nets in Salmanshahr, the southern Caspian Sea. From March 2011 to April 2012, 224 specimens representing 4 gobiid species, belonging to...

متن کاملStudy on length frequency and catch per unit effort of sturgeon spawners in the fishing grounds of Mazandaran province
In this study, the catch composition and the catch per unit effort (CPUE) of sturgeon spawners caught by the gill net were investigated in the fishing grounds of Mazandaran province in two regions 3 and. Sampling and data collection of sturgeon spawning fish was done seasonally from 7 fishing grounds using gill nets with a mesh size of 150 mm. The results of the Chi-square test showed that the...
