SEAPODYM is a model developed for investigating spatiotemporal dynamics of fish populations under the influence of both fishing and the environment. The model simulates age-structured population dynamics using advection–diffusion–reaction equatio

We present a modelling approach to estimate and predict the dynamics of highly migratory albacore tuna populations in the South Pacific and Atlantic oceans. We use the previously developed model SEAPODYM (Spatial Ecosystem And POpulation DYnamics Mod

Archival and pop-up satellite archival tags have been widely used to study the move- ment dynamics in many marine pelagic species. Recent advances in light-based geolocation models have enabled better estimation of the geographical positions of tagge

A Spatial Ecosystem and Population Dynamic Model (SEAPODYM) is used in a data assimilation study aiming to estimate model parameters that describe dynamics of Pacific skipjack tuna population on ocean-based scale. The model based on advection–diffu

Tracking marine animals with electronic tags has become an indispensable tool in understanding biology in relation to movement. Combining light based geolocation estimates with an underlying movement model has proved helpful in reconstructing the mos

A coherent model is presented to estimate the most probable track of geographic positions directly from a series of light measurements. The model estimates two geographic positions per day, without reducing the daily light data to two threshold cross

Data from pop-up satellite archival tags (PSATs) deployed on Atlantic bluefin tuna (Thunnus thynnus) in 1999, 2000, and 2002 were analyzed synthetically using variants of a state–space statistical model to estimate tag shedding positions, in situ p

An approach to integrate sea surface temperature (SST) measurements into estimates of geolocations calculated by changes in ambient light level from data downloaded from pop-up satellite archival tags (PSAT) is presented. The model is an extension of

Despite being one of the most common pieces of information used in assessing the status of fish stocks, relative abundance indices based on catch per unit effort (cpue) data are notoriously problematic. Raw cpue is seldom proportional to abundance ov
