Length frequency, length-weight relationship and catch per unit of effort (CPUE) of Longtail tuna (Thunnus tonggol) and Yellowfin tuna (Thunnus albacares) caught by purse seine in Oman Sea
Length frequency, length-weight relationship and catch per unit of effort (CPUE) for longtail tuna and yellowfin tuna in purse seine fishing were studied in Oman Sea between July and August 2015. Length range and mean of longtail tuna were obtained 56-98 and 74.13±0.41 cm, respectively. Length range and mean of yellowfin tuna were obtained 51-128 and 74.62±0.46 cm, respectively. The length-weig...
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 کاملCatch-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 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...
