Calibrating virtual population analysis for fisheries stock assessment

Population dynamics and potential of fisheries stock enhancement: practical theory for assessment and policy analysis.

The population dynamics of fisheries stock enhancement, and its potential for generating benefits over and above those obtainable from optimal exploitation of wild stocks alone are poorly understood and highly controversial. I review pertinent knowledge of fish population biology, and extend the dynamic pool theory of fishing to stock enhancement by unpacking recruitment, incorporating regulati...

ss3sim: An R Package for Fisheries Stock Assessment Simulation with Stock Synthesis

Simulation testing is an important approach to evaluating fishery stock assessment methods. In the last decade, the fisheries stock assessment modeling framework Stock Synthesis (SS3) has become widely used around the world. However, there lacks a generalized and scriptable framework for SS3 simulation testing. Here, we introduce ss3sim, an R package that facilitates reproducible, flexible, and...

Estimation of Otolithes ruber stock with virtual population analysis in the Northwest area of the Persian Gulf

Stock assessment of Otolithes ruber was carried out using Virtual Population Analysis (VPA) method in the coastal waters of Northwest Persian Gulf. Catch and length frequency data during 2002-2012 were converted to age frequency. The maximum of stock number and biomass were observed in age group 1 and 2 respectively. The minimum of stock number and biomass were observed age group 6. The maximum...
