Sustainable fisheries management requires accurate stock assessment and an understanding of how targeted populations vary over space time respond to external stressors. Commercial fishery catch rate data (i.e. per unit effort; CPUE) are widely used assess performance can provide a measure abundance. However, changes in environmental conditions influence the two determinants CPUE, i.e. catchabil...

In this study it is aimed that determining effect of some social and demographic properties on Catch Per Unit Effort (CPUE) in Uluabat Lake anglers. A total 375 interview applied with angler from April – 2015 to May 2016 monthly period. Mean CPUE values each was estimated as 1.36 fish/hr (0.08-5.67). Generalized additive models (GAMs) used for evaluating the data set. Variables model were age (...

the present study considered the situation of kilka stocks in last decades by using overfished biomass threshold, fishing effort ratio and fishing mortality proxy during 1991-2010. the cpue index of anchovy and mixed-species of kilka indicated an undepleted from 1991 to 2000. in 2000, the cpue ratio declined to close to the “in danger” region, and subsequently collapsed to “overfished” region f...

The relationship between growth in white crappie, Pomoxis annularis Rafinesque, and climate, lake morphometry and population density was studied in 103 Texas reservoirs. Growth of age-0 through age-3 white crappie was significantly (P £ 0.05) related to latitude, growing season and surface area. Growth of age-1 through age-5 white crappie also was related to annual precipitation. Multiple linea...

The purpose of this study was to analyze the catch per fishing effort (CPUE) Red Snapper (Lutjanus sp) resources and comparison catches based on gear used. results showed that in waters Lewalu Village period January – December 2021 fluctuated tended decrease with an average CPUE value 11,499 kg/trip/year. from Fishing Line Rawai Units shows there is a difference catch.

The purpose of this study is to determine the effect escape gap cylinder folding trap on catch per unit effort (CPUE), rate, composition, and size fish caught in coastal waters Tuban Regency. research was conducted November 2019 by deploying 60 units ten experimental fishing trips at different locations. traps were 20 without gap, with an 3 cm x 6 cm, 4 7 cm. Overall, experiments resulted a col...
