Akaike's information criterion ( AIC), which is widely used as a criterion of model selection in fish population dynamics, is known to have a bias in not only small samples but also large samples. Consistency was proposed as a property of the information criteria available in large samples. We carried out model selection in ANOVA-type model corresponding to catch per unit effort (CPUE) standardization using consistent information criteria (Bayesian information criterion, Hannan–Quinn, or consistent AIC), which satisfy the asymptotic desirable property called consistency. The results of the model selections between these consistent criteria and AIC are different. Computer simulations using a linear regression model show that the selection performances of consistent information criteria in large samples are good compared with that of AIC.

    The skipjack tuna is the main tuna species caught in Brazil with pole and live-bait. Samples taken during 1984-1986 and the 2004-2009 periods provided length, weight and age data. A comparison of the population structure was made showing a decrease in the median and means of fork length in the...

    The common dentex Dentex dentex (Linnaeus, 1758) is an iconic marine coastal fish in the Mediterranean Sea. It is a demersal sparid fish (0-200 m), that grows to a maximum length of 100 cm and a weight of 13 kg, with a relatively long life span (more than 20 years). As a high trophic level...

    The stock size of sandfish in the northern Sea of Japan was estimated by a virtual population analysis (VPA) and sensitivity analyses were attempted on the VPA estimate. The stock size estimates were approximately 600–900 million until 1975, but since 1976 they have rapidly decreased. In...
